Student Topic Booking

By Shahabuddin Amerudin

Introduction

The Project Booking Web System was created to address the need for a fair, efficient, and organized method of project topic selection for students. This platform, accessible at Project Booking 2024, allows students to reserve topics based on available slots and offers administrators clear insights into student preferences and booking trends. Through real-time updates, comprehensive display of reserved topics, and user-friendly instructions, the system enables students to make informed decisions while ensuring transparency. This article explores the system’s requirements, design, development, implementation, and functional advantages, aiming to highlight how this project booking system enhances both user experience and administrative efficiency.

Requirements Analysis

To start with, requirements analysis was central to the development of the project booking system, identifying critical elements needed to deliver an effective solution for all users. A key requirement was to allow each student to make only one booking, which prevents multiple topic reservations and ensures fair access to available slots. In a context where multiple students may have similar interests, ensuring that each student has equal opportunity to reserve a topic promotes a balanced and equitable experience (Lee, 2021). Additionally, maintaining accuracy in entries was deemed essential; each student was instructed to type their full name accurately to avoid duplicates and inconsistencies, while system validation features ensure duplicate entries are automatically blocked. Slot management was another core requirement. The system was designed to provide six name slots for the first topic and five for all other topics, reflecting both anticipated demand and ensuring adequate space within popular selections (Jackson, 2022). The system’s slot allocation dynamically manages availability, updating in real-time to prevent overbooking. Transparency was emphasized by making all booking records—including student name, date, and time in GMT/UTC—publicly accessible, ensuring both students and administrators have visibility over booked slots. Finally, implementing a first-come, first-served processing model was crucial to meet the fairness requirement, thus prioritizing bookings based on the earliest submissions and reinforcing the equitable distribution of topics.

System Design

The design process emphasized the need for a user-friendly and minimalist interface. The booking page itself is streamlined, focusing solely on available topics and respective slots. With simplicity as a design pillar, the page reduces any cognitive load for students by allowing them to quickly and clearly view their options without unnecessary distractions. Instructions and error-prevention prompts are strategically displayed to prevent common mistakes; these prompts remind users to check their entries and follow booking rules. Each page is designed with an emphasis on minimizing error potential through prompts and reminders that reinforce accuracy (Nielsen & Norman, 2018). Dynamic slot availability was achieved through real-time data updates, ensuring students see only currently available slots. This responsive feedback loop allows students to make real-time decisions without needing to refresh or reload the page, supporting efficient topic allocation. The booked list page, accessible to all, displays all confirmed bookings with details organized for quick scanning. The list’s structured layout further enhances usability, aligning with principles of transparent data display and supporting students and staff in verifying booking records.

Development Process

The development of the project booking system utilized PHP for back-end programming due to its server-side scripting capabilities and compatibility with the institution’s web environment. PHP’s role in dynamic form processing and data validation was essential in enforcing the single-booking restriction and interacting seamlessly with the JSON database, which stored all booking data. JSON was chosen for its stability, speed, and reliable structure, critical for managing a small volume of data entries and rapid data retrieval. To maintain consistent timestamps for each booking, the system implemented GMT/UTC as the standard time format. However, to cater specifically to users in Malaysia, the PHP function date_default_timezone_set('Asia/Kuala_Lumpur') was applied to align with Malaysia Standard Time (MST), providing a consistent time reference across bookings and avoiding confusion that may arise from varying time zones (Jackson, 2022). The front end was designed with HTML, CSS, and JavaScript, technologies that collectively ensure a responsive and accessible interface compatible across devices. Error handling and validation checks were integrated using PHP’s form validation, displaying relevant feedback messages when incorrect or incomplete information is submitted. This validation process helps maintain data accuracy while guiding users through corrective actions as needed.

Implementation and Testing

In terms of implementation and testing, rigorous testing scenarios were conducted to verify that the system met all requirements and provided a seamless booking experience. Each test scenario confirmed that the single-booking rule was properly enforced; attempts to book multiple topics by a single user were consistently blocked, meeting the core requirement for fair access. The system’s real-time slot update was also tested under scenarios simulating concurrent bookings by multiple users, with the system proving highly responsive and maintaining accurate slot availability. Testing also validated that all entries in the publicly accessible booked list displayed correctly, showing the student’s name, date, and GMT/UTC time stamp. Additionally, instructions were evaluated for clarity, with each prompt and error message contributing to improved user guidance and reduced booking errors.

Usage Outcomes and Benefits

Since its implementation, the project booking web system has demonstrated substantial benefits in efficiency and user experience. By automating the project topic assignment process, the system has reduced the need for manual intervention, freeing up administrative time and resources. Students are able to book slots with ease, relying on real-time availability feedback to make informed choices, while administrators benefit from clear insights into booking trends and data. The transparent, publicly accessible booking list has enhanced accountability, enabling students to confirm their own bookings at any time. User satisfaction has increased as well, owing to the system’s intuitive interface and clear instructions. Error rates have significantly dropped, allowing students to reserve topics with greater confidence and efficiency (Smith & Brown, 2020).

Future Enhancements

Looking to the future, a few enhancements could further improve the system’s capabilities and user experience. One potential enhancement is an automated email confirmation feature, which would provide students with a tangible record of their booking and reinforce the accuracy of their submission. Another suggested feature is an admin dashboard, which would offer faculty greater control over slot management and allow for necessary adjustments in real-time. Additionally, integrating the system with student profiles could streamline the booking process further, reducing manual entry requirements and minimizing potential errors due to misspelled names.

Conclusion

Overall, the project booking web system exemplifies a well-organized, effective solution for managing academic project topics. By adhering to key principles of usability, transparency, and fairness, this system has streamlined the booking process, providing equitable access to topics and enhancing both student and administrator experiences. Potential future enhancements, such as email confirmation, an admin dashboard, and student profile integration, could further support the system’s goals of user-centered efficiency and functionality, ensuring it remains a valuable tool in academic project management.

Analysis Phase of a Web and Mobile Integrated Mapping System

Analysis Phase of a Web and Mobile Integrated Mapping System: Tools, Diagrams, and Suitable Models

By Shahabuddin Amerudin

The analysis phase of a web and mobile integrated mapping system is a vital part of the system development process, where all requirements are gathered, assessed, and organized to ensure a smooth and effective design and implementation of the system. This phase involves understanding the functional and non-functional requirements, identifying the key features needed by end-users, and setting up technical specifications that the system must adhere to. A variety of tools and methodologies are employed during this phase to collect, analyze, and document user requirements, and to visualize the system’s structure through diagrams and models.

Several tools are essential during the analysis phase to manage requirements and collaborate efficiently. Jira or Trelloare often used as project management tools to document and organize user stories, tasks, and system requirements. These tools enable the development team to track progress, prioritize features, and ensure that all stakeholders are aligned with the project’s goals. For documentation, tools like Microsoft Word or Google Docs are used to create a detailed System Requirement Specification (SRS) document, which outlines the functional and non-functional requirements, system constraints, and user expectations. The SRS acts as a blueprint that guides the subsequent design and development phases. To gather feedback from a broad range of users, tools like SurveyMonkey or Google Formscan be deployed. These tools help collect input from field officers, environmental researchers, and administrators regarding the features they need, such as real-time GPS tracking or layered map visualizations. This feedback is crucial in shaping the final system.

For collaboration and communication, tools like ZoomMicrosoft Teams, or Slack are essential. These platforms allow real-time interaction between the stakeholders and the development team, ensuring that any ambiguities or issues with the system requirements are clarified immediately. In addition to verbal communication, visual collaboration tools like Lucidchart or Microsoft Visio are used to create diagrams that visually represent the system’s architecture and interactions. These tools help stakeholders and developers conceptualize the system structure, ensuring a common understanding across the team.

The analysis phase also involves the creation of various diagrams and models that help visualize the system’s behavior and data flow. Use Case Diagrams are particularly important as they provide a high-level view of the system by identifying the key interactions between users and the system. For example, in a web and mobile integrated mapping system, different actors, such as field officers, administrators, and environmental researchers, interact with the system to upload geospatial data, view environmental data layers, or generate reports. Tools like Lucidchart or Draw.io can be used to create these diagrams, offering a clear representation of the user’s interactions with system functions.

Another critical diagram is the Data Flow Diagram (DFD), which models how data moves through the system. In a mapping system, a DFD might illustrate how data is collected via mobile devices in the field, transmitted to the backend server, processed in a geospatial database, and then displayed on the web interface. DFDs are essential in understanding how data flows across various system components, ensuring that data from multiple sources—such as sensors or manually uploaded environmental data—is processed smoothly and efficiently. Tools like Draw.io or Lucidchart can be used to create these diagrams.

For database designEntity-Relationship Diagrams (ERD) are vital. ERDs model the relationships between different data entities in the geospatial database. For instance, entities such as “Location,” “Environmental Data,” and “User” will be represented as entities, and their relationships will define how data is connected. This helps in structuring the geospatial database to manage vast amounts of data efficiently. Tools such as MySQL Workbench or Visual Paradigm can be employed to create these ERDs, ensuring that the data relationships are well understood and that the database will support the system’s needs effectively.

User Journey Maps are also valuable in the analysis phase, as they depict the entire process a user goes through when interacting with the system. For instance, the journey map might illustrate the steps a field officer takes to collect environmental data using a mobile device, upload the data to the system, and visualize it on a web platform. Creating these journey maps using tools like Miro or UXPressia helps in identifying potential pain points and areas where the system can be improved to optimize the user experience.

Finally, Context Diagrams are created to provide an overview of the system’s boundaries and its interactions with external systems. In the context of the mapping system, a context diagram might show how the system interacts with external GPS services, third-party environmental databases, or cloud storage solutions. Tools like Visio or Lucidchartcan be used to create context diagrams, providing a simplified yet comprehensive view of how the system integrates with external components.

When it comes to choosing an appropriate model for this type of system, the Unified Modeling Language (UML) is often used, as it is a standardized modeling language that provides a visual representation of the system’s functionality. UML diagrams, such as Class DiagramsUse Case Diagrams, and Sequence Diagrams, allow developers to map out the system’s architecture, object relationships, and sequence of interactions, ensuring that all components are well-structured. In terms of development models, both the Waterfall and Agile models can be suitable, depending on the project’s scope. If the requirements are clear and unlikely to change, the Waterfall Model—with its linear approach—works well as it ensures that each phase is completed before moving to the next. However, for projects where requirements might evolve, an Agile Model is preferable due to its iterative approach, allowing for continuous feedback and adjustment.

The Prototyping Model is also highly effective in the analysis phase of system development. By developing early versions or mock-ups of key system features, such as the map interface or data upload functionality, stakeholders can provide feedback on the look and feel of the system. This allows developers to make early adjustments based on user input, reducing the risk of major revisions later in the project.

In conclusion, the analysis phase of the web and mobile integrated mapping system is a complex process that involves several tools, diagrams, and models to ensure that the system is designed according to the user’s needs and technical specifications. Tools like Jira, Lucidchart, and Google Forms help organize and document requirements, while diagrams such as Use Case Diagrams, Data Flow Diagrams, and ERDs provide essential visualizations of the system’s architecture and data flow. The models used during this phase, whether UML, Waterfall, Agile, or Prototyping, are chosen based on the project’s scope and adaptability, ensuring that the system is robust, scalable, and aligned with user expectations.

Peranan AI dalam Pembangunan Perisian dan Aplikasi

Ai coding

Oleh Shahabuddin Amerudin

Kecerdasan Buatan (AI) kini menjadi salah satu teknologi teras dalam pembangunan perisian dan aplikasi, membawa revolusi dalam cara perisian dibina, diuji, dan diselenggara. Dengan kemajuan terkini dalam pembelajaran mesin, automasi, dan pemprosesan bahasa semula jadi (NLP), AI membantu mempercepatkan pembangunan kod, meningkatkan kecekapan pengujian perisian, dan memudahkan integrasi analitik pintar ke dalam aplikasi. Namun, penggunaan teknologi ini juga datang dengan cabaran, termasuk isu keselamatan, kebergantungan pada platform tertentu, dan potensi risiko kebergantungan kepada alat AI yang terlalu tinggi. Artikel ini akan mengupas bagaimana AI membantu dalam proses pembangunan perisian serta alat-alat terkini yang boleh digunakan, dengan memberi fokus kepada kelebihan, keburukan, risiko, dan cara mengatasi isu-isu tersebut.

AI dalam Penulisan Kod Automatik

Salah satu kegunaan AI yang paling meluas dalam pembangunan perisian adalah penulisan kod automatik. Contoh utama ialah GitHub Copilot, yang menggunakan model Codex, satu varian daripada GPT-3 yang dibangunkan oleh OpenAI. GitHub Copilot membantu pengaturcara dengan mencadangkan barisan kod semasa mereka menaip, berdasarkan konteks yang diberikan, serta memberikan penyelesaian kepada masalah sintaks atau logik yang mungkin dihadapi. Ini mempercepatkan pembangunan, terutamanya bagi pengaturcara yang baru mempelajari bahasa pengaturcaraan baru atau yang bekerja dalam projek besar yang memerlukan pengoptimuman masa. Namun, terdapat kebimbangan dari segi hak cipta kerana Copilot menggunakan data kod dari repositori terbuka, yang mungkin menyebabkan penggunaan kod tanpa izin (OpenAI, 2022).

Selain itu, perisian seperti Replit Ghostwriter turut menawarkan kemampuan penulisan kod automatik dengan membantu dalam melengkapkan kod dan debugging. Alat ini sesuai untuk pemula yang ingin mempercepatkan proses pembelajaran mereka dengan bantuan AI. Kelebihan terbesar perisian seperti ini adalah ia mempercepatkan proses pembangunan dan mengurangkan jumlah kesilapan kod semasa proses penulisan. Namun begitu, risiko yang signifikan adalah kebergantungan yang tinggi kepada cadangan AI tanpa pengaturcara memahami asas logik atau struktur kod tersebut, yang boleh membawa kepada pembinaan kod yang tidak cekap atau rentan (Replit, 2023).

AI dalam Ujian Perisian Automatik

Ujian perisian merupakan fasa kritikal dalam pembangunan, dan AI telah membuktikan peranannya dalam mempercepatkan proses ini. Alat seperti Testim menggunakan kecerdasan buatan untuk mencipta dan menjalankan ujian automatik. Alat ini bukan sahaja mengurangkan masa yang diperlukan untuk ujian, tetapi juga mengadaptasi dirinya mengikut perubahan dalam perisian. Selain itu, ia membantu dalam pengujian regresi dan memastikan perisian tetap stabil walaupun selepas banyak perubahan dibuat. Walaupun AI menawarkan cara yang lebih pantas dan lebih konsisten untuk menguji perisian, kelemahan utamanya adalah AI mungkin gagal mengesan beberapa isu kompleks yang hanya dapat dilihat melalui pengujian manual (Testim, 2023).

Perisian lain seperti Mabl turut menonjol sebagai alat ujian automatik yang dibantu AI. Mabl mampu mengenal pasti bug dan menjalankan analisis mendalam mengenai prestasi perisian. Kelebihannya ialah Mabl boleh digunakan untuk pengujian berterusan, memastikan kualiti perisian dipantau sepanjang kitaran pembangunan. Namun, satu cabaran yang timbul ialah kebergantungan kepada pengujian automatik boleh membawa kepada pengabaian pengujian manual yang lebih menyeluruh, terutama untuk aplikasi kompleks yang memerlukan ujian secara empirik (Mabl, 2023).

AI untuk Analitik dan Pembelajaran Mesin

Dalam domain pembelajaran mesin dan analitik, alat seperti TensorFlow telah menjadi pilihan utama bagi pembangunan model pembelajaran mesin dan pembelajaran mendalam (deep learning). TensorFlow adalah rangka kerja sumber terbuka yang menyokong pelbagai tugas seperti pemprosesan bahasa semula jadi, penglihatan komputer, dan analitik ramalan. Kelebihan utama TensorFlow ialah kebolehannya untuk menyokong model berskala besar yang memerlukan pemprosesan data yang kompleks. Ini menjadikan TensorFlow amat sesuai untuk aplikasi seperti pengenalan gambar, ramalan trend perniagaan, atau pengelasan data teks. Walaupun begitu, TensorFlow mempunyai keluk pembelajaran yang agak curam, menjadikannya lebih sesuai untuk pembangun yang mempunyai latar belakang yang kuat dalam AI dan pembelajaran mesin (TensorFlow, 2022).

Selain TensorFlow, Hugging Face menjadi platform utama bagi pemprosesan bahasa semula jadi (NLP). Hugging Face menyediakan model pra-latihan seperti GPT, BERT, dan RoBERTa, yang membolehkan pembangun membina aplikasi berasaskan teks dengan cepat dan cekap. Aplikasi NLP seperti chatbots, analisis sentimen, dan penerjemahan bahasa menjadi lebih mudah dengan bantuan model ini. Kelebihan utama alat ini adalah kemampuannya untuk menyesuaikan model-model sedia ada dengan data khusus tanpa memerlukan latihan model dari awal. Namun, satu cabaran yang mungkin dihadapi ialah model AI pra-latihan tidak selalu serasi sepenuhnya dengan semua jenis data, memerlukan penalaan lanjut bagi mencapai prestasi optimum (Hugging Face, 2023).

AI No-Code: Revolusi Pembangunan Aplikasi

Perkembangan AI juga telah mendorong kebangkitan platform no-code dan low-code, di mana sesiapa sahaja boleh membangunkan aplikasi tanpa perlu menulis kod. Platform seperti Bubble membolehkan pengguna membina aplikasi web interaktif dengan cepat dan mudah tanpa memerlukan pengalaman teknikal yang mendalam. AI diintegrasikan dalam platform ini untuk membantu pengguna menyesuaikan antaramuka pengguna (UI) dan mengotomasi beberapa proses pembangunan. Kelebihan no-code ialah ia membuka pintu kepada lebih ramai pembangun bukan teknikal untuk mencipta aplikasi, sekali gus mengurangkan halangan kemasukan ke dalam dunia pembangunan perisian (Bubble, 2023).

Walau bagaimanapun, no-code datang dengan beberapa kekangan. Platform no-code seperti OutSystems menawarkan kawalan terhad terhadap logik dalaman aplikasi, menjadikannya kurang sesuai untuk aplikasi yang memerlukan pengendalian data atau logik kompleks. Selain itu, masalah penguncian vendor (vendor lock-in) juga timbul kerana pengguna mungkin sukar untuk memindahkan aplikasi mereka ke platform lain jika terdapat keperluan untuk mengubah teknologi atau memperluasnya (OutSystems, 2023).

Kebaikan, Keburukan, dan Risiko Penggunaan AI dalam Pembangunan

Kebaikan utama penggunaan AI dalam pembangunan perisian adalah peningkatan kecekapan dan kelajuan. AI membantu mempercepatkan penulisan kod, mengurangkan masa pengujian perisian, dan membolehkan pembangunan aplikasi yang lebih pintar dan adaptif. Penggunaan AI dalam no-code juga membolehkan pengguna tanpa latar belakang teknikal untuk membangunkan aplikasi, sekali gus meningkatkan aksesibiliti dalam pembangunan perisian. Namun, keburukan utama yang berkaitan dengan AI adalah kebergantungan terlalu tinggi kepada sistem AI, yang boleh menyebabkan kehilangan kawalan terhadap kualiti dan keselamatan perisian. Pengguna mungkin gagal memahami logik asas yang diperlukan untuk pembangunan perisian yang cekap kerana terlalu bergantung kepada cadangan AI yang diberikan secara automatik (Rahwan et al., 2023).

Risiko keselamatan juga menjadi isu utama, terutama apabila AI digunakan dalam ujian perisian atau pembangunan no-code. Aplikasi yang dibangunkan mungkin mempunyai kerentanan yang tidak dikesan atau kod yang tidak dioptimumkan dengan baik. Penguncian vendor dalam platform no-code juga boleh menyulitkan proses migrasi aplikasi atau integrasi dengan sistem lain, menghalang skalabiliti jangka panjang aplikasi tersebut (Benfield, 2023).

Cadangan dan Penutup

Bagi mengatasi isu dan risiko yang dikaitkan dengan penggunaan AI dalam pembangunan perisian, beberapa pendekatan boleh diambil. Pertama, adalah penting untuk mengimbangi penggunaan AI dengan pengujian manual dan audit keselamatan yang ketat. Pembangun perlu memastikan bahawa aplikasi yang dibangunkan diuji secara teliti untuk sebarang kelemahan yang mungkin tidak dapat dikesan oleh AI. Kedua, platform no-code perlu dipilih dengan berhati-hati, dan sebaiknya yang menyokong API terbuka untuk memudahkan migrasi dan integrasi di masa hadapan. Ketiga, latihan dan pendidikan mengenai teknologi AI perlu diperluas supaya pengguna dapat memahami kekangan dan kelebihan AI, sekali gus mengelakkan kebergantungan sepenuhnya terhadap alat ini tanpa memahami asas pembangunan perisian (Hoffman, 2022).

Dengan pendekatan yang berhati-hati, AI berpotensi menjadi salah satu alat yang paling kompetitif dalam pembangunan perisian dan aplikasi, namun ia memerlukan penggunaan yang bijaksana untuk mengelakkan risiko yang berkaitan.

Mengimbangi Peranan Universiti dan Industri dalam Pembangunan Teknologi

campus

Universiti sering dianggap sebagai pusat inovasi dan pembangunan teknologi. Di sinilah teori-teori baru diasah, penyelidikan mendalam dijalankan, dan teknologi baru direka serta diuji. Dalam konteks ini, universiti sewajarnya memainkan peranan sebagai pelopor dalam pembangunan teknologi. Berbanding industri yang fokus kepada keuntungan, universiti berfungsi sebagai landasan untuk penyelidikan jangka panjang tanpa batasan komersial yang ketara. Oleh itu, ada asas untuk menyatakan bahawa universiti perlu lebih maju dari segi teknologi, kerana mereka membentuk dan meneroka konsep yang kemudiannya boleh digunakan oleh industri.

Namun, realitinya tidak selalu begitu. Universiti kadang-kadang ketinggalan dalam teknologi praktikal yang digunakan oleh industri, disebabkan oleh beberapa faktor seperti bajet yang terhad, birokrasi, serta ketiadaan hubungan yang erat antara akademia dan industri. Universiti sering kali tertinggal dari sudut aplikasi kerana teknologi baru dalam industri berkembang pesat disebabkan persaingan pasaran dan dorongan untuk inovasi yang mendatangkan keuntungan. Contohnya, teknologi seperti kecerdasan buatan (AI), pembelajaran mesin, dan Internet Benda (IoT) berkembang dengan pesat di syarikat-syarikat teknologi sebelum universiti dapat membina kurikulum atau sistem pendidikan yang relevan dan menyeluruh.

Salah satu isu yang sering diketengahkan adalah jurang antara apa yang diajar di universiti dan keperluan industri sebenar. Banyak program universiti cenderung mengutamakan aspek teori berbanding aplikasi, menjadikan graduan kurang bersedia untuk menghadapi cabaran teknologi terkini di tempat kerja. Industri sering kali memerlukan teknologi praktikal yang dapat menyelesaikan masalah dengan segera, sedangkan universiti mungkin terperangkap dalam kajian teori yang memerlukan masa yang lama untuk berkembang menjadi sesuatu yang berguna dari segi komersial.

Namun, perbincangan ini harus adil, kerana misi utama universiti adalah untuk menghasilkan ilmu pengetahuan baru dan membangun teknologi untuk jangka masa panjang, bukan sekadar mengikuti arus perkembangan teknologi semasa. Penyelidikan di universiti selalunya lebih fundamental dan tidak serta-merta mempunyai aplikasi komersial, tetapi ia adalah asas kepada inovasi teknologi yang kemudian dikomersialkan oleh industri.

Untuk menyelesaikan masalah jurang teknologi antara universiti dan industri, kerjasama strategik perlu ditingkatkan. Universiti boleh memainkan peranan yang lebih penting dalam pembangunan teknologi melalui penyelidikan kolaboratif bersama industri. Ini dapat memastikan teknologi yang sedang dibangunkan di universiti selaras dengan keperluan semasa industri, sambil universiti juga dapat mengeksplorasi teknologi masa depan yang masih belum diterokai oleh industri. Contoh yang baik ialah model pembangunan inkubator teknologi yang melibatkan penyelidik akademik dan syarikat untuk membangunkan prototaip teknologi yang boleh diuji dan dikomersialkan.

Walaupun begitu, wujud masalah lain apabila kurangnya insentif bagi pensyarah dan penyelidik untuk terlibat dalam kerjasama industri, kerana sistem penilaian universiti lebih mengutamakan penerbitan akademik berbanding impak ekonomi atau teknologi yang dihasilkan. Akibatnya, teknologi yang dibangunkan di universiti mungkin terlewat memasuki pasaran atau tidak memenuhi keperluan industri semasa.

Isu lain yang mempengaruhi keupayaan universiti untuk mengungguli industri dari segi teknologi adalah keterbatasan sumber kewangan. Pembiayaan untuk penyelidikan dan pembangunan teknologi di universiti, khususnya di negara membangun, sering kali tidak mencukupi untuk membiayai pembelian teknologi terkini atau membangunkan makmal penyelidikan yang canggih. Sebaliknya, syarikat-syarikat besar mampu membiayai penyelidikan dan pembangunan mereka sendiri dan membeli peralatan teknologi terkini.

Universiti sepatutnya memainkan peranan lebih besar sebagai pembangun teknologi, bukan sekadar pengguna. Namun, realiti menunjukkan bahawa terdapat beberapa cabaran yang perlu diatasi, termasuk jurang antara teori dan aplikasi, kekurangan kerjasama dengan industri, dan kekangan pembiayaan. Walaupun ada beberapa universiti yang mampu mengungguli industri dari segi pembangunan teknologi (misalnya dalam bidang penyelidikan fundamental), kebanyakan universiti memerlukan pendekatan yang lebih strategik dan kolaboratif untuk memastikan teknologi mereka sentiasa relevan dan terkehadapan.

Media Sosial dan GIS Untuk Pengumpulan dan Analisis Data Ruang

social media

Oleh Shahabuddin Amerudin

Pengenalan 

Dalam era digital ini, media sosial telah berkembang menjadi platform yang bukan sahaja digunakan untuk berinteraksi secara sosial, tetapi juga sebagai sumber data yang kaya untuk pelbagai analisis. Integrasi media sosial dengan Sistem Maklumat Geografi (GIS) membuka peluang besar dalam pelbagai sektor seperti pemantauan bencana, keselamatan, dan analisis alam sekitar. Dengan ciri geotag yang disertakan dalam kebanyakan platform media sosial seperti Twitter, Instagram, dan Facebook, data dapat dianalisis secara spatial untuk menghasilkan pemahaman yang lebih mendalam mengenai corak dan tren di lapangan.

Pemanfaatan GIS dan Media Sosial dalam Pengumpulan Data Ruang 

Penggunaan data geotag daripada media sosial membolehkan pengumpulan maklumat secara masa nyata. Setiap kali pengguna membuat kemas kini di media sosial, data seperti lokasi, masa, dan kandungan disertakan. Data ini boleh dimasukkan ke dalam GIS untuk menganalisis pelbagai aspek seperti aktiviti manusia, perubahan penggunaan tanah, dan tren sosial yang berkembang. Sebagai contoh, kajian oleh Resch et al. (2020) menunjukkan bahawa data dari Twitter boleh digunakan untuk memahami corak mobiliti bandar dan tingkah laku pengguna di lokasi tertentu.

Pemantauan Bencana Alam dengan Media Sosial dan GIS 

Salah satu aplikasi penting integrasi media sosial dengan GIS ialah dalam pemantauan dan respons terhadap bencana alam. Sebagai contoh, apabila bencana seperti banjir atau gempa bumi berlaku, ramai pengguna media sosial melaporkan situasi tersebut melalui platform seperti Twitter atau Facebook. Dengan menggunakan alat GIS, laporan ini dapat dipetakan untuk menyediakan gambaran tentang kawasan yang terjejas. Ini membantu agensi penyelamat dalam menentukan kawasan yang memerlukan bantuan segera dan meningkatkan kecekapan dalam pengurusan bencana. Kajian oleh Crooks, Croitoru, dan Stefanidis (2013) menunjukkan bahawa media sosial boleh menyediakan maklumat awal yang tidak terdapat dalam sumber tradisional semasa bencana alam. Sebagai contoh, semasa Taufan Sandy melanda Amerika Syarikat pada 2012, banyak maklumat bencana diperoleh daripada media sosial yang membantu dalam merancang tindakan balas yang pantas.

Analisis Persepsi Awam Menggunakan GIS dan Media Sosial 

GIS juga dapat digunakan untuk memahami persepsi awam terhadap sesuatu tempat atau peristiwa. Sentimen yang dikongsi di media sosial boleh dianalisis menggunakan GIS untuk menilai bagaimana pendapat awam berbeza berdasarkan lokasi. Data ini sangat berguna untuk pemantauan persepsi terhadap pembangunan bandar, pemuliharaan alam sekitar, atau sebarang isu sosial yang mendapat perhatian. Ghaffarian et al. (2022) menggunakan data media sosial untuk memahami sentimen awam terhadap pembangunan lestari di kawasan bandar. GIS digunakan untuk memetakan sentimen tersebut dan melihat perbezaan persepsi antara kawasan bandar dan luar bandar.

Pembangunan Pelancongan dan Pemasaran Tempatan 

Data geospatial dari media sosial boleh dimanfaatkan dalam bidang pelancongan. Melalui penggunaan GIS, lokasi yang sering disebut atau dikunjungi oleh pengguna media sosial dapat dianalisis untuk mengenal pasti kawasan tarikan pelancong yang popular. Pihak berkuasa tempatan dan agensi pelancongan boleh menggunakan maklumat ini untuk merancang strategi pemasaran yang lebih baik serta memperbaiki infrastruktur di lokasi-lokasi pelancongan yang popular. Kajian oleh Sigala (2018) membuktikan bahawa integrasi GIS dan data media sosial memainkan peranan penting dalam pemetaan destinasi pelancongan serta dalam perancangan strategi pemasaran digital.

Penglibatan Komuniti dan Kesedaran Awam melalui Media Sosial 

Penglibatan komuniti adalah aspek penting dalam memastikan kejayaan sesuatu projek, terutamanya yang melibatkan aktiviti pemetaan atau pemantauan alam sekitar. Melalui media sosial, GIS dapat digunakan untuk menarik minat masyarakat menyertai aktiviti seperti pemetaan komuniti (crowdsourcing) atau pemantauan persekitaran. Sebagai contoh, dalam projek pemantauan alam sekitar, pengguna media sosial dapat diarahkan untuk memuat naik gambar atau video dari lokasi tertentu yang boleh membantu pihak berkuasa memantau perubahan dalam alam sekitar. Barve et al. (2020) menunjukkan bagaimana data daripada media sosial boleh digunakan untuk pemetaan biodiversiti di kawasan-kawasan tertentu, dengan melibatkan komuniti dalam proses pengumpulan data.

Kesimpulan 

Penggunaan media sosial bersama GIS memberikan peluang yang signifikan untuk pengumpulan dan analisis data ruang secara lebih dinamik dan masa nyata. Dari pemantauan bencana hingga kepada analisis persepsi awam, teknologi ini mempercepatkan proses pengambilan keputusan dan memperkukuh perancangan berdasarkan data yang lebih tepat dan mendalam. Dalam persekitaran yang semakin pantas berubah, pendekatan ini bukan sahaja membantu dalam memahami corak semasa, malah membantu dalam penyediaan respons yang lebih cepat dan berkesan.

Implementing a Comprehensive Atlas Documenting the Life of Prophet Muhammad

atlas arabia

By Shahabuddin Amerudin

Introduction

The documentation of the Prophet Muhammad’s life has historically been preserved through manuscripts, biographies (Sirah), and religious texts such as Hadith collections. However, modern technological advances, particularly Geographic Information Systems (GIS) and digital visualization tools, allow for a more dynamic, immersive, and educational method of mapping these significant events and locations. This paper proposes a detailed plan for the development of a comprehensive atlas documenting the life of Prophet Muhammad, blending historical research with cutting-edge geospatial technologies and interactive educational tools.

1. Research and Data Collection

Team Formation

The foundation of this project lies in assembling a multidisciplinary team. This team would consist of historians, Islamic scholars, GIS specialists, and cartographers. Collaboration with research institutions, universities, and Islamic history centers is crucial to ensure historical accuracy. According to recent trends in academic collaboration, involving specialized experts from various disciplines enhances the credibility of the project (Kamel, 2023). This collaboration not only helps in accurate data collection but also fosters an environment of peer review and validation.

Source Verification

The success of the project hinges on the careful selection and verification of sources. Historical accuracy can be achieved by relying on original and authenticated Islamic texts. These sources include collections of Hadith, the Prophet’s biographies, and primary Islamic historical literature. A rigorous verification process must be followed, whereby historians and scholars cross-reference these sources to establish a firm chronological and geographical framework for mapping the Prophet’s life.

As Sardar (2022) emphasized in his research on historical data digitization, source verification is essential for ensuring that modern interpretations do not deviate from established historical facts. This method of verification allows for precise mapping of key locations in the Prophet’s life, such as his birthplace in Makkah, his migration route (Hijra) to Madinah, and sites of important events like the Battle of Badr.

Data Validation

Historical data should undergo a strict validation process in collaboration with academic institutions and Islamic research centers. This step will ensure that the historical locations and events are accurately reflected in the maps. Ongoing research into ancient Islamic landmarks and pilgrimage routes can also contribute to refining the geographical scope of the atlas. Recent developments in geospatial archaeology have shown the importance of cross-validating historical findings with modern geographic data (Bollati et al., 2023).

2. Geospatial Mapping

Geographic Coordinates

Once the historical events are verified, determining the precise or approximate geographic coordinates is the next crucial step. GIS technologies can overlay historical data on modern maps. Historical landmarks, including locations from the Prophet’s early life, migration, and key battles, can be pinpointed using satellite imagery and historical texts. According to Muqaddam (2023), GIS mapping has proven essential in projects involving ancient pilgrimage routes, offering visual clarity for historical timelines.

Satellite Imagery

Utilizing satellite imagery tools like Google Earth and more advanced data sets from satellites enables the project to capture detailed modern views of ancient landscapes. This imagery, combined with historical data, enhances the accuracy of the atlas. Satellite images also provide a unique perspective for visualizing how key locations have evolved over time, making the Prophet’s journey more relatable to contemporary audiences.

Integration of Historical Data with Maps

Platforms like ArcGIS and QGIS serve as powerful tools to overlay historical data on modern maps. By using time-based layers, events such as the migration to Madinah or battles like Badr and Uhud can be visualized chronologically. According to Al-Qadi (2024), integrating GIS with historical research enables more precise documentation, allowing for dynamic mapping of Islamic history.

Precision Mapping

Accurate topographical data is critical for reflecting the landscape during the Prophet’s lifetime. Modern GIS tools offer precise topographical mapping that captures the contours and features of the terrain as it might have existed during the time of the Prophet. This allows for the creation of maps that mirror the physical and environmental context of the events.

3. Technology Integration

Interactive Online Platform

An interactive web-based platform will be a key deliverable, offering users the ability to explore maps and events interactively. Features such as zooming into specific locations, viewing timelines, and accessing supplementary information about each site will be essential. Recent projects like the Mapping Makkah initiative demonstrate how such platforms can be powerful educational tools (Rizvi, 2022).

Mobile Application

To increase accessibility, a mobile application mirroring the web platform’s functionality should be developed. The app could incorporate geolocation features for users traveling to historical sites, allowing them to access real-time data and visualizations on the Prophet’s journey. Mobile-based platforms offer wide accessibility, making the project globally relevant.

Database and Backend Management

A robust database system, such as MySQL combined with PostGIS for spatial data, should be implemented to manage the extensive geospatial and historical data. This ensures that the data is stored securely, can be easily queried, and is scalable for future updates. PostGIS adds spatial data management capabilities to traditional database systems, allowing for efficient handling of geospatial queries (Johnson, 2023).

4. Visualization and Educational Tools

Historical Diagrams and Visual Pathways

Key events in the Prophet’s life can be transformed into visual diagrams and pathways. Software like Adobe Illustrator can be used for designing diagrams, while tools like D3.js can offer interactive visualizations that users can explore online. Research has shown that visual learning aids are essential in historical education, offering deeper engagement (Nour, 2023).

Maps, Illustrations, and Multimedia

Static and interactive maps will visualize the Prophet’s life in stages. Images, diagrams, and even 3D models of historical sites should accompany these maps to create a more immersive experience. As highlighted by Shahid (2024), integrating multimedia with GIS projects enhances user engagement by providing various layers of context.

Exhibitions and Publications for Children

To engage younger audiences, simplified maps and illustrations will be developed. This child-friendly material will be designed to introduce key aspects of the Prophet’s biography in an age-appropriate format. Using storytelling and simplified diagrams, children will be able to learn about the Prophet’s life in an engaging and relatable way.

5. Collaboration and Conferences

Institutional Collaborations

Partnering with Islamic universities, research centers, and international institutions will provide the project with a broader scholarly perspective. Peer reviews and collaborative research will ensure that the atlas maintains high academic standards. Conferences and workshops involving global scholars will foster discussion on Islamic landmarks and how modern technology can aid their preservation.

International Conference

An international conference dedicated to the findings and significance of this project will allow scholars worldwide to discuss Islamic history and its preservation. As noted by Abdullah (2022), international collaboration fosters broader knowledge sharing and opens new avenues for interdisciplinary research.

6. Publication and Dissemination

Print and Digital Atlases

Both print and digital versions of the atlas will be published, ensuring that the project reaches a wide audience. The digital version will include interactive maps, while the print version will provide a scholarly reference for academic institutions.

7. Public Engagement

Exhibitions and Events

Exhibitions using virtual and augmented reality (VR/AR) can be organized, allowing visitors to virtually “experience” the Prophet’s journey. Virtual exhibits can attract a wider audience, offering an immersive experience that showcases Islamic history (Ahmed, 2023).

Social Media Campaigns

To raise awareness, social media campaigns on platforms like YouTube, Instagram, and Twitter can share visuals, lectures, and behind-the-scenes insights from the project. As highlighted by Khayat (2024), social media plays a vital role in public history projects by engaging younger, tech-savvy audiences.

Conclusion

The comprehensive atlas documenting the life of Prophet Muhammad represents a fusion of historical scholarship and modern technology. By using GIS, satellite imagery, and interactive tools, the project will offer an immersive educational experience that not only preserves Islamic heritage but also brings it to life for a global audience.

King Abdulaziz Foundation Uses Advanced Technology to Map Prophet Muhammad’s Steps

By Shahabuddin Amerudin

Introduction

The integration of modern technology with historical research is transforming the way we understand and preserve the past. One such remarkable endeavor is the project initiated by the King Abdulaziz Foundation for Research and Archives (Darah), aimed at creating a comprehensive atlas documenting the life of the Prophet Muhammad. This initiative, which reflects Saudi Arabia’s dedication to preserving Islamic and Arab history, leverages advanced geospatial technologies to map and visualize the key locations and events from the Prophet’s life.

This paper explores the methodology, technological integration, and broader implications of this project, examining how it bridges traditional historical scholarship with cutting-edge technological advancements.

Historical Foundation and Significance

The Prophet Muhammad’s life holds immense significance in Islamic history, and documenting his journey is crucial for Muslims around the world. The King Abdulaziz Foundation, known as Darah, has a long-standing commitment to preserving Islamic heritage, and this project builds on its expertise in developing historical atlases. According to Sultan Alawairidhi, the official spokesperson of Darah, “The project stems from Darah’s commitment to preserving Islamic and Arab history, building on its expertise in developing historical atlases” (Alshammari, 2024).

This initiative was launched under the leadership of King Salman, who chaired Darah’s board when the project was initiated several years ago, and it continues to receive the support of Crown Prince Mohammed bin Salman and supervision from Prince Faisal bin Salman, chairman of Darah’s board of directors. The project aligns with Saudi Arabia’s broader goals of preserving its historical and religious heritage and sharing it with a global audience.

Methodology: The Fusion of Historical Research and Modern Technology

The atlas project relies on an extensive team of historians, researchers, and scholars from universities and research centers. These experts meticulously source data from original texts such as the Hadith, biographies (Sirah), and other Islamic historical literature. According to Alawairidhi, the foundation is “using reliable sources and advanced technologies to ensure the project’s accuracy” (Alshammari, 2024). This meticulous approach ensures the accuracy of the geographical and historical data being compiled.

A key aspect of this project is the integration of geographic information systems (GIS) to map and visualize the significant locations associated with the Prophet’s life. This involves determining geographic coordinates for important sites such as the Prophet’s birthplace in Makkah, his migration route to Madinah (Hijra), and the locations of key battles. These coordinates are cross-referenced with historical texts to ensure precision.

Technological Integration: GIS, Satellite Imagery, and Interactive Maps

The use of cutting-edge technologies is central to this project. The team at Darah employs geographic coordinates, satellite imagery, and GIS tools to document and map significant landmarks. “By harnessing these technologies in the service of the noble Prophetic biography, we aim to achieve the atlas’s objectives and collaborate with relevant institutions and specialized researchers in universities and scientific research centers,” Alawairidhi explained (Alshammari, 2024).

The atlas is designed to visually represent key moments in the Prophet’s life, transforming historical narratives into accessible visual formats. Satellite imagery, for example, helps to provide modern views of the ancient landscapes where historical events took place. GIS enables the overlay of these historical events onto current geographical maps, allowing for an interactive exploration of the Prophet’s journey.

An interactive online platform is planned for the project, which will allow users to explore these maps and timelines in detail. This platform will include zoomable maps, timelines of events, and additional resources such as diagrams, illustrations, and educational materials. The project is also set to include a mobile application, which will offer a similar user experience, with added geolocation features for visitors traveling to historical Islamic sites.

Visualization and Educational Tools

The atlas will not only serve as a scholarly reference but will also include a range of educational tools to engage different audiences. These tools include maps, illustrations, diagrams, and images that transform the Prophet’s life into visual pathways. By integrating both static and interactive elements, the atlas will serve as both an educational and devotional resource.

Moreover, specialized materials will be developed for children, using simplified maps and illustrations to make the Prophet’s biography accessible to younger audiences. This ensures that the project caters to a wide demographic, from scholars to laypeople and from adults to children.

Public Engagement and Outreach

In addition to the atlas, the project will involve the creation of supplementary materials and public engagement initiatives. An exhibition on the Prophet’s biography is planned, which will showcase key locations, maps, and visual materials from the atlas. This exhibition will serve as an interactive experience for visitors, allowing them to engage with the historical material in a meaningful way. There are also plans for specialized publications, conferences, and workshops that will further disseminate the findings of the project.

One of the project’s most significant elements is the planned international conference on the historical sites featured in the Prophet’s biography. This conference will bring together scholars from around the world to discuss the historical and religious significance of these sites and how they can be preserved and shared with future generations.

Conclusion

The King Abdulaziz Foundation’s atlas documenting the life of Prophet Muhammad is an ambitious and pioneering project that exemplifies the fusion of historical research with modern technology. By using GIS, satellite imagery, and interactive maps, the project offers a visual and educational representation of the Prophet’s life, making it accessible to a global audience.

As the project progresses, it promises to not only preserve Islamic history but also to serve as a scholarly resource and an educational tool for Muslims worldwide. The use of technology in this context demonstrates how modern advancements can be harnessed to preserve and share religious and cultural heritage in innovative ways. As Alawairidhi aptly stated, “We aim to achieve the atlas’s objectives and collaborate with relevant institutions and specialized researchers in universities and scientific research centers” (Alshammari, 2024), showcasing the project’s collaborative and forward-thinking nature.

Isu dan Cabaran dalam Sistem Alamat Nasional Malaysia

postcard

Oleh Shahabuddin Amerudin

Abstrak
Sistem Alamat Nasional di Malaysia menghadapi beberapa isu dan cabaran yang boleh menjejaskan keberkesanannya. Artikel ini membincangkan masalah utama dalam sistem alamat Malaysia, termasuk kekurangan piawaian seragam, kurangnya integrasi teknologi geospatial, data yang tidak dikemaskini, dan perbezaan dalam pengurusan alamat antara pihak berkuasa tempatan. Kesimpulan mencadangkan langkah-langkah untuk meningkatkan keberkesanan sistem alamat.

1. Pengenalan
Sistem alamat merupakan komponen penting dalam pengurusan bandar dan perkhidmatan logistik, memainkan peranan utama dalam memudahkan penghantaran barang, perkhidmatan kecemasan, dan perancangan bandar. Di Malaysia, sistem alamat nasional berfungsi untuk menyokong pelbagai aplikasi yang memerlukan ketepatan lokasi. Walau bagaimanapun, terdapat beberapa isu utama yang menjejaskan keberkesanan sistem ini. Kekurangan piawaian yang seragam, kurangnya integrasi teknologi geospatial, data yang tidak dikemaskini, dan perbezaan dalam pengurusan alamat antara pihak berkuasa tempatan adalah antara cabaran yang dihadapi. Artikel ini bertujuan untuk mengkaji isu-isu tersebut dengan lebih mendalam dan mencadangkan langkah-langkah penyelesaian yang boleh meningkatkan sistem alamat nasional di Malaysia.

2. Ketiadaan Piawaian Alamat yang Seragam
Kekurangan piawaian seragam dalam penulisan dan penggunaan alamat di Malaysia merupakan masalah utama dalam sistem alamat negara. Di kawasan bandar, alamat biasanya lebih teratur, namun di kawasan luar bandar dan pedalaman, terdapat ketidakkonsistenan yang ketara dalam penomboran rumah, nama jalan, dan penggunaan kod pos (Karim, 2021). Ketidaksesuaian ini menyukarkan pengurusan data alamat secara sistematik dan menyebabkan cabaran dalam perkhidmatan penghantaran, khususnya di kawasan luar bandar.

3. Kurangnya Integrasi Teknologi Geospatial
Walaupun teknologi geospatial, seperti Sistem Maklumat Geografi (GIS), digunakan oleh beberapa agensi seperti Jabatan Ukur dan Pemetaan Malaysia (JUPEM), integrasi penuh antara teknologi ini dan sistem alamat masih belum tercapai. Ketiadaan data alamat yang bergeocode secara menyeluruh menyukarkan pemetaan alamat dengan tepat, terutama dalam perancangan bandar dan pembangunan infrastruktur (Hashim & Abdullah, 2020).

4. Data yang Tidak Dikemaskini
Sistem alamat di Malaysia sering kali tidak dikemaskini secara berkala, menyebabkan ketidaktepatan dalam pangkalan data. Perubahan alamat akibat pembangunan baru atau pengubahsuaian struktur tidak dimasukkan dengan segera ke dalam sistem, yang mengakibatkan maklumat yang ada menjadi lapuk dan tidak relevan. Isu ini amat ketara di kawasan yang pesat membangun seperti Lembah Klang (Rashid, 2021).

5. Ketidaktentuan Penggunaan Nama Jalan dan Kawasan
Nama jalan yang tidak konsisten atau tidak rasmi juga merupakan masalah besar dalam sistem alamat nasional. Kadangkala, satu jalan boleh mempunyai dua atau lebih nama bergantung pada kawasan atau pihak berkuasa tempatan yang bertanggungjawab. Ketidakkonsistenan ini bukan sahaja mengelirukan penduduk setempat tetapi juga memberi cabaran besar kepada penyedia perkhidmatan seperti perkhidmatan kecemasan, pos, dan logistik (Samad & Ibrahim, 2019).

6. Pengurusan Kod Pos yang Tidak Seragam
Kod pos di Malaysia masih menjadi isu kerana terdapat kawasan yang luas mempunyai satu kod pos, sementara kawasan yang lebih kecil mempunyai kod pos yang berbeza. Ini menyebabkan kekeliruan dalam pengurusan penghantaran dan pengesanan lokasi yang tepat, terutama di kawasan yang berkembang pesat. Sistem kod pos yang tidak berstruktur ini juga menjejaskan kecekapan logistik dan perkhidmatan penghantaran (Ismail, 2020).

7. Perbezaan dalam Pengurusan Alamat Antara Pihak Berkuasa Tempatan
Pihak berkuasa tempatan (PBT) di Malaysia mempunyai kaedah yang berbeza dalam menguruskan dan mengemaskini alamat di kawasan masing-masing. Sesetengah PBT menggunakan sistem yang lebih maju dan teratur, sementara yang lain masih bergantung pada sistem manual atau kurang tersusun. Ketidaksamaan ini menjejaskan kualiti data alamat di seluruh negara (Karim, 2021).

8. Kurang Kesedaran Awam dan Akses kepada Sistem Alamat
Masalah lain adalah kurangnya kesedaran awam mengenai kepentingan penggunaan alamat yang tepat dan piawaian dalam penulisan alamat. Ramai penduduk, khususnya di kawasan luar bandar, mungkin tidak menyedari bagaimana penggunaan alamat yang tepat boleh membantu dalam banyak aspek kehidupan seharian, termasuk perkhidmatan penghantaran, keselamatan, dan kecemasan (Rashid, 2021).

9. Cabaran Infrastruktur di Kawasan Luar Bandar
Di kawasan luar bandar dan pedalaman, banyak lokasi tidak mempunyai nama jalan atau nombor rumah yang jelas, menjadikan sistem alamat yang ada kurang efektif. Tanpa infrastruktur yang memadai, usaha untuk menyelaraskan alamat di kawasan-kawasan ini menjadi sukar, yang seterusnya menghalang keberkesanan sistem alamat nasional (Samad & Ibrahim, 2019).

10. Isu Data Alamat dan Kesukaran Navigasi
Salah satu isu utama dalam sistem alamat di Malaysia adalah kekurangan data yang konsisten untuk rujukan. Penomboran rumah sering kali didistribusikan secara sembarangan di banyak lokasi, menyebabkan berlakunya redundansi dalam penamaan serta variasi dalam ejaan dan pelabelan. Kadangkala, destinasi dengan nama yang serupa boleh menyebabkan kekeliruan. Selain itu, alamat yang panjang dan mempunyai banyak komponen menjadi tidak efisien untuk tujuan navigasi. Alamat-alamat ini bukan sahaja memerlukan pengenalan yang kompleks tetapi juga sukar untuk dimasukkan ke dalam komputer atau peranti navigasi. Akibatnya, pengguna perlu menghabiskan banyak masa untuk memasukkan koordinat atau rentetan aksara yang panjang. Tambahan pula, alamat sering kali tidak berkaitan dengan koordinat geografi dan memerlukan proses geokod sebelum boleh dipaparkan pada peta (Wan Othman et al., 2015).

Kesimpulan
Sistem Alamat Nasional di Malaysia menghadapi pelbagai cabaran termasuk ketiadaan piawaian seragam, kurangnya integrasi teknologi, data yang tidak dikemaskini, dan perbezaan dalam pengurusan alamat antara pihak berkuasa tempatan. Untuk meningkatkan keberkesanan sistem alamat, perlu ada usaha bersepadu untuk mewujudkan piawaian alamat yang seragam, memperluas penggunaan teknologi geospatial, dan mengemaskini data secara berkala. Selain itu, kesedaran awam mengenai kepentingan penggunaan alamat yang betul juga perlu ditingkatkan.

Abstrak 
Sistem alamat yang tersusun dan bersepadu merupakan komponen penting dalam perancangan bandar, pengurusan infrastruktur, dan pembangunan ekonomi sesebuah negara. Artikel ini membincangkan pelbagai contoh Sistem Alamat Nasional yang telah dibangunkan di seluruh dunia, serta kesesuaian pendekatan tersebut untuk diterapkan di Malaysia. Beberapa sistem terkenal seperti USPS di Amerika Syarikat, Postcode Address File (PAF) di United Kingdom, dan Geocoded National Address File (G-NAF) di Australia dianalisis bagi memberi pandangan kepada pembangunan sistem yang berkesan di Malaysia. Selain itu, artikel ini juga membincangkan keperluan Malaysia membangunkan sistemnya yang tersendiri dengan mengambil kira kepelbagaian geografi dan demografi tempatan.

1. Pengenalan 
Sistem Alamat Nasional merupakan struktur asas bagi pengurusan data alamat yang teratur dan konsisten. Di Malaysia, usaha ke arah pembangunan sistem ini dilihat semakin penting dengan pertumbuhan pesat sektor bandar, keperluan untuk perkhidmatan penghantaran yang lebih baik, dan penggunaan maklumat geospatial bagi perancangan pembangunan. Dalam konteks ini, Malaysia boleh belajar daripada beberapa negara yang telah berjaya membangunkan sistem alamat nasional yang komprehensif.

2. Sistem Alamat Nasional: Satu Tinjauan Global 
Beberapa negara telah membangunkan sistem alamat yang menyeluruh, masing-masing dengan keunikan tersendiri untuk menguruskan maklumat alamat bagi kegunaan kerajaan, sektor swasta, dan orang awam. Antara contoh terbaik termasuk:

2.1 United States Postal Service (USPS) Address Management System 
Sistem USPS di Amerika Syarikat adalah antara yang paling maju, menggunakan kod ZIP (Zone Improvement Plan) sebagai penanda alamat yang unik untuk setiap kawasan (Lemay & Wilson, 2021). Sistem ini digunakan bukan sahaja untuk perkhidmatan pos, tetapi juga bagi perancangan bandar, sistem kecemasan, dan perkhidmatan awam yang lain. Penggunaan kod ZIP telah berjaya memudahkan pengurusan logistik dan meningkatkan kecekapan perkhidmatan penghantaran pos di seluruh negara (Brockmann, 2018).

2.2 Postcode Address File (PAF) – United Kingdom 
Di United Kingdom, Royal Mail menguruskan Postcode Address File (PAF), yang berfungsi sebagai pangkalan data komprehensif bagi semua alamat yang menggunakan kod pos. Data ini digunakan oleh agensi kerajaan, perkhidmatan kecemasan, dan sektor swasta (Johnston & Pattie, 2017. PAF terkenal dengan ketepatan dan kekerapan kemas kini, menjadikannya antara sistem alamat yang paling bersepadu di dunia (Thompson, 2020).

2.3 Geocoded National Address File (G-NAF) – Australia 
Australia pula menggunakan Geocoded National Address File (G-NAF), yang mengandungi lebih daripada 13 juta alamat yang diberi geocode, membolehkan integrasi dengan teknologi pemetaan geospatial. Sistem ini digunakan untuk pelbagai tujuan seperti perancangan bandar, perkhidmatan kecemasan, dan pelaporan statistik oleh agensi kerajaan dan swasta (Harvey & Bowman, 2019). G-NAF memanfaatkan data dari pelbagai sumber untuk memastikan integriti dan ketepatan maklumat (Grant, 2021).

3. Kesesuaian Sistem Global untuk Malaysia 

Malaysia mempunyai kepelbagaian geografi dan demografi yang unik, daripada bandar-bandar besar di Semenanjung hingga kawasan luar bandar di Sabah dan Sarawak. Oleh itu, penting untuk Malaysia membangunkan sistem alamat yang bukan sahaja berfungsi untuk kawasan bandar tetapi juga kawasan luar bandar yang terpencil. G-NAF Australia dan PAF United Kingdom adalah dua contoh yang boleh dijadikan rujukan utama untuk Malaysia kerana sistem ini:

  • Menyediakan pangkalan data alamat yang bersepadu dan dikemaskini secara berkala (Grant, 2021).
  • Menggunakan integrasi geospatial, membolehkan alamat dipetakan dengan tepat dan digunakan oleh pelbagai agensi kerajaan dan sektor swasta (Harvey & Bowman, 2019) (Johnston & Pattie, 2017).

Dengan menggunakan elemen-elemen dari sistem ini, Malaysia boleh membangunkan Sistem Alamat Nasional yang sesuai dengan keperluan tempatan. Sistem ini juga boleh disepadukan dengan teknologi semasa seperti Geographic Information System (GIS) untuk kegunaan perancangan bandar, sistem logistik, dan perkhidmatan kecemasan (Johnston & Pattie, 2017).

4. Cadangan untuk Sistem Alamat Nasional Malaysia 

Malaysia boleh membangunkan sistem alamatnya yang tersendiri dengan ciri-ciri berikut:

4.1 Pangkalan Data Bersepadu dan Dikemaskini
Sistem alamat Malaysia perlu mempunyai pangkalan data yang berpusat dan boleh dikemaskini secara automatik melalui kerjasama dengan agensi tempatan dan kerajaan pusat. Penggunaan teknologi blockchain mungkin boleh dipertimbangkan untuk memastikan integriti data dan mengelakkan perubahan tanpa kebenaran (Lin & Liao, 2021).

4.2 Integrasi dengan Teknologi Geospatial
Penggunaan GIS dapat memastikan setiap alamat dipetakan dengan tepat, membantu pelbagai sektor seperti perkhidmatan kecemasan dan perancangan infrastruktur. Malaysia sudah mempunyai infrastruktur GIS yang baik melalui kerjasama dengan agensi seperti Jabatan Ukur dan Pemetaan Malaysia (JUPEM), dan ini boleh dimanfaatkan untuk integrasi yang lebih luas (JUPEM, 2022).

4.3 Piawaian Alamat yang Konsisten
Satu piawaian alamat yang jelas perlu diwujudkan untuk memastikan konsistensi dalam penomboran dan penamaan alamat di seluruh negara. Kod pos yang diseragamkan juga penting untuk memastikan urusan perkhidmatan awam dan swasta dapat dijalankan dengan lancar (Thompson, 2020).

5. Kesimpulan 

Pembangunan Sistem Alamat Nasional yang komprehensif di Malaysia adalah penting untuk memudahkan perancangan bandar, pengurusan logistik, dan pelaksanaan dasar kerajaan yang lebih berkesan. Malaysia boleh belajar dari sistem yang berjaya dilaksanakan di negara seperti Australia dan United Kingdom, tetapi juga perlu menyesuaikannya dengan keperluan tempatan. Dengan kerangka yang betul, sistem ini dapat menyumbang kepada pertumbuhan ekonomi, peningkatan infrastruktur, dan mempertingkatkan kualiti hidup rakyat.

From AHP to GWR in Sinkhole Susceptibility Modeling with Advanced GIS Methods

sinkhole

Introduction

Rosdi et al. (2017) made significant strides in understanding sinkhole susceptibility in Kuala Lumpur and Ampang Jaya by combining Geographic Information Systems (GIS) with the Analytical Hierarchical Process (AHP). Their work laid a solid foundation for assessing sinkhole risk, but there remains an opportunity to refine and enhance these models using more advanced spatial analysis techniques. One promising approach is Geographically Weighted Regression (GWR), which has the potential to improve both the accuracy and granularity of sinkhole susceptibility assessments. This article examines how incorporating GWR, along with other advanced GIS methodologies, could lead to more precise and insightful analyses of sinkhole hazards.

1. Application of Geographically Weighted Regression (GWR)

Geographically Weighted Regression (GWR) represents an evolution from traditional regression models by allowing for spatial variability in the relationships between variables. Unlike global models that assume a uniform relationship across the study area, GWR acknowledges that these relationships can vary from one location to another. This spatial flexibility is crucial for understanding sinkhole formation, as it reveals how different factors influence sinkhole risk in distinct geographical contexts (Fotheringham et al., 2002).

Applying GWR to the analysis of sinkhole susceptibility in Kuala Lumpur and Ampang Jaya could illuminate how key factors such as lithology, groundwater level decline, soil type, land use, and proximity to groundwater wells affect sinkhole risk differently across various regions. For instance, the impact of lithology might be more pronounced in areas with specific geological features, while groundwater decline could play a more significant role in other areas. By capturing these spatial differences, GWR would provide a more nuanced and accurate understanding of sinkhole susceptibility (Brunsdon et al., 1996).

GWR offers several advantages for sinkhole susceptibility analysis. It allows for localized insights by identifying areas where certain factors disproportionately affect sinkhole formation, thereby enabling more targeted and effective mitigation strategies. Additionally, by accounting for spatial heterogeneity, GWR can enhance the accuracy of susceptibility models, leading to improved predictions and risk assessments. The results from GWR can also be visualized as spatially varying coefficients, providing a clear and interpretable representation of how each factor’s influence varies across the study area (Fotheringham et al., 2002).

2. Integration of High-Resolution Remote Sensing Data

The current study’s reliance on existing land use data can be significantly improved by incorporating high-resolution remote sensing imagery from satellites or unmanned aerial vehicles (UAVs). This approach would allow for the development of more accurate and up-to-date land use and land cover maps, which are essential for assessing areas at risk of sinkhole formation (Li et al., 2019).

High-resolution satellite imagery also enables time-series analysis, which can track changes in land use and land cover over time. Such analysis is crucial for identifying trends and patterns that contribute to sinkhole development, including urban expansion, deforestation, and alterations in groundwater extraction practices (Wu et al., 2015).

3. Incorporation of Additional Spatial Variables

In addition to the factors considered in the current study—lithology, groundwater decline, soil type, land use, and proximity to groundwater wells—incorporating topographical factors such as slope, elevation, and aspect could provide additional insights. These topographical variables often influence water drainage and soil stability, both of which are important in sinkhole formation (Gao et al., 2014).

Furthermore, integrating detailed hydrological modeling into the GIS analysis could enhance our understanding of how water movement through the landscape affects sinkhole susceptibility. Simulating scenarios of heavy rainfall or prolonged drought could provide valuable information on their impact on groundwater levels and sinkhole risk (Beven & Kirkby, 1979).

4. Improved Data Integration and Validation Techniques

A more comprehensive GIS framework that integrates diverse datasets—such as geological surveys, hydrological models, and remote sensing data—would facilitate a thorough analysis of sinkhole risk. Utilizing machine learning techniques could further help in identifying complex patterns and interactions among various factors that contribute to sinkhole formation (Hengl et al., 2015).

Expanding the sinkhole inventory and performing rigorous cross-validation of the model would enhance its reliability. Incorporating data from other regions with similar geological and environmental conditions could also test the model’s generalizability and robustness (Chen et al., 2020).

5. Exploring Alternative Multicriteria Decision-Making (MCDM) Techniques

The Fuzzy AHP method could bolster the robustness of the susceptibility model by addressing the uncertainty and vagueness inherent in geological and hydrological data. This technique provides a way to incorporate and manage these uncertainties in decision-making processes (Saaty, 2008).

The Weight of Evidence (WoE) method is another promising approach, particularly for binary classification problems such as identifying areas prone to sinkholes. WoE calculates the probability of sinkhole occurrence based on the presence or absence of certain factors, offering a probabilistic perspective on risk assessment (Bonham-Carter, 1994).

Conclusion

The study by Rosdi et al. (2017) significantly advanced our understanding of sinkhole susceptibility in Kuala Lumpur and Ampang Jaya. However, the integration of advanced GIS methods such as Geographically Weighted Regression (GWR), high-resolution remote sensing data, and additional spatial variables holds the potential to further enhance the accuracy and utility of sinkhole susceptibility models. By exploring these and other advanced techniques, future research could provide more reliable tools for predicting and mitigating sinkhole hazards, contributing to safer and more resilient urban environments.

Advancing Urban Planning with GeoAI through Global Street Network Analysis

GeoAI and planning

By Shahabuddin Amerudin

Introduction

Geographic Artificial Intelligence (GeoAI) integrates Geographic Information Systems (GIS) with artificial intelligence (AI), offering advanced capabilities for urban planning and development. This convergence allows for a more nuanced understanding of spatial dynamics and provides tools to address complex urban challenges. By harnessing GeoAI, urban planners can optimize infrastructure, manage resources more efficiently, and create sustainable urban environments. This article delves into how GeoAI can be applied to enhance city planning by analyzing street network configurations across different global cities.

Understanding GeoAI

GeoAI represents the intersection of spatial data analysis and AI technologies, including machine learning and deep learning. Traditional GIS methods are enhanced by AI’s ability to process and analyze large volumes of data, identify patterns, and make predictions. GeoAI utilizes machine learning algorithms to interpret satellite imagery, sensor data, and other spatial inputs, offering insights that traditional GIS might miss. For instance, deep learning models can analyze urban growth patterns and infrastructure changes by processing high-resolution imagery and historical data, enabling planners to predict future trends and assess the impact of proposed developments (El Asmar et al., 2022).

Analyzing Street Network Patterns with GeoAI

Cities around the world exhibit diverse street network configurations, from grid patterns to organic layouts and radial designs. GeoAI provides sophisticated tools to analyze these configurations, optimizing urban infrastructure and managing traffic flow effectively.

Grid Patterns

Cities with grid-like street networks, such as Vancouver and Beijing, can leverage GeoAI for various urban planning applications. In Vancouver, where the street layout is characterized by a regular grid, GeoAI can enhance traffic management by analyzing traffic flow data and predicting congestion. Machine learning algorithms can process historical traffic data to identify traffic bottlenecks and recommend solutions such as optimized traffic signal timings and route adjustments. For example, AI models can analyze patterns in traffic congestion and propose infrastructure improvements to alleviate these issues, leading to a more efficient urban traffic system (Zhou et al., 2023).

In Beijing, the grid pattern reflects historical planning priorities and centralized development. GeoAI can assist in optimizing land use within these grids by integrating spatial data with AI-driven insights. This approach can help manage high-density urban areas effectively, ensuring that new developments align with existing infrastructure and urban planning goals. AI algorithms can also support the planning of mixed-use developments, which can enhance urban density and improve land use efficiency (Li et al., 2023).

Organic Patterns

Cities such as Sydney and Cape Town feature more organic, irregular street layouts influenced by natural topographies. GeoAI can address the unique challenges posed by these layouts by using deep learning to analyze satellite imagery and topographical data. For instance, AI models can identify patterns in urban growth and predict traffic congestion in areas with irregular street networks. By integrating environmental data, GeoAI can propose development strategies that harmonize urban expansion with natural landscapes (Chen et al., 2023).

In Sydney, where street patterns are shaped by hills and waterways, GeoAI can analyze how new infrastructure projects might impact the surrounding environment. This analysis helps planners design solutions that minimize disruption and integrate seamlessly with the natural landscape. Similarly, in Cape Town, AI-driven insights can support sustainable development by assessing the environmental impact of infrastructure projects and recommending design modifications to protect natural features (Gibson, 2004).

Radial and Concentric Patterns

Cities with radial and concentric street networks, such as Moscow and Paris, benefit from GeoAI in several ways. Moscow’s radial layout, characterized by streets radiating outwards from a central point, can be optimized using GeoAI to improve traffic flow around central hubs. AI algorithms can analyze historical traffic data and real-time information to recommend adjustments to traffic signals and routing, reducing congestion and enhancing traffic management (Wu et al., 2023).

Paris, with its complex radial network and intricate street patterns, presents challenges for urban planning. GeoAI can assist in preserving historical street layouts while accommodating modern infrastructure needs. AI-driven analyses can help maintain Paris’s historical character while integrating contemporary infrastructure, ensuring that urban development respects the city’s cultural heritage and meets current urban demands (Wang et al., 2023).

Adapting to Topographical Influences

GeoAI excels in incorporating topographical considerations into urban planning, particularly in cities with challenging terrains.

Environmental Sensitivity

Cities with diverse topographies, such as Cape Town, require careful integration of new developments with natural landscapes. GeoAI can model the environmental impact of infrastructure projects and propose design modifications to mitigate disruption. For example, AI models can evaluate how new roads or buildings might affect mountainous terrains and suggest design solutions that minimize environmental impact. This capability is crucial for balancing urban growth with environmental preservation (Zhang et al., 2023).

Sustainable Urban Design

GeoAI also supports sustainable urban design by analyzing data related to green spaces, energy consumption, and pollution. AI algorithms can propose strategies for expanding green infrastructure, managing urban sprawl, and improving overall sustainability. In rapidly developing cities like Dubai, AI-driven scenario modeling can simulate various development strategies, assessing their impacts on environmental and infrastructural sustainability. This approach helps planners make informed decisions that promote sustainable urban growth (Liu et al., 2023).

Enhancing Urban Planning with GeoAI

Data-Driven Decision Making

GeoAI provides powerful tools for data-driven urban planning. AI models can analyze existing infrastructure, predict future needs, and recommend new developments. In cities like Kuala Lumpur, GeoAI can support planning by integrating spatial data with AI-driven insights. This integration helps planners make informed decisions about infrastructure investments, such as new roads and public facilities, ensuring that development aligns with current and future urban needs (Yang et al., 2023).

Scenario Modeling

GeoAI enables the simulation of various urban planning scenarios, predicting their impacts on traffic, land use, and environmental factors. This capability is particularly valuable for cities experiencing rapid development. In Dubai, for example, AI-driven scenario modeling can provide insights into the outcomes of different development strategies, guiding planners in selecting the most effective approaches for sustainable growth (Xu et al., 2023).

Emergency Response

GeoAI enhances emergency response planning by modeling response times and identifying critical areas for emergency services. AI models can optimize the placement of emergency services and predict response times, improving the city’s ability to handle crises effectively. This capability ensures that urban environments are better prepared for emergencies and can respond swiftly to incidents (Li et al., 2023).

Conclusion

GeoAI represents a significant advancement in urban planning, offering enhanced capabilities for analyzing and optimizing city environments. By integrating GIS with AI technologies, GeoAI provides deeper insights into street network patterns, environmental considerations, and infrastructure development. As cities continue to evolve, leveraging GeoAI will be crucial for creating efficient, sustainable, and resilient urban environments. The ability to analyze complex spatial data and predict future trends enables planners to make informed decisions that support both growth and sustainability.

Leveraging GIS for Enhanced Urban Planning Insights from Global Street Networks

network

By Shahabuddin Amerudin

Introduction

Geographic Information Systems (GIS) have become indispensable tools in urban planning, offering the capability to analyze spatial data and derive actionable insights for optimizing city layouts. By examining street network configurations from various global cities, GIS technologies can be leveraged to address urban planning challenges, improve infrastructure, and enhance overall city functionality. This discussion explores how GIS can be applied to different street network patterns, taking into account both historical and contemporary planning strategies.

1. Street Network Analysis and Planning

1.1. Grid vs. Organic Patterns

GIS technologies provide robust methods for analyzing the efficiency and effectiveness of different street network patterns. Understanding these patterns helps in optimizing urban infrastructure and improving traffic management.

  • Grid Patterns: Cities like Vancouver and Beijing are characterized by grid-like street networks. These grids often result in highly regular, rectangular blocks, which facilitate straightforward navigation and efficient traffic flow.
    • Efficiency and Traffic Management: GIS can be used to model traffic patterns and identify optimal routes within grid networks. For example, Vancouver’s grid layout allows for easy integration of public transportation routes and bike lanes. GIS analysis can optimize traffic signals, reduce congestion, and improve emergency response times (Batty, 2005).
    • Land Use and Density: Grids typically support higher urban densities and mixed land uses. GIS tools can analyze land use patterns and ensure that infrastructure development aligns with the grid’s efficiency. This analysis helps in planning for mixed-use developments and ensuring that residential, commercial, and recreational spaces are well-integrated (Goodchild, 2007).
  • Organic Patterns: Cities with organic street patterns, such as Sydney and Cape Town, often develop around natural features and historical growth patterns. These layouts can present unique challenges for urban planning.
    • Integration with Natural Features: GIS can model how natural landscapes influence urban development and identify areas where infrastructure needs to adapt to topographical constraints. For instance, Sydney’s street network, shaped by its hilly terrain and waterways, requires careful planning to integrate new developments without disrupting existing natural features (Gibson, 2004).
    • Traffic and Infrastructure Challenges: The irregularity of organic patterns can lead to traffic congestion and inefficient public transportation routes. GIS can be used to analyze traffic flow and develop solutions that improve connectivity while preserving the city’s natural character (Brabham, 2013).

1.2. Radial and Concentric Patterns

Radial and concentric street patterns, as seen in Moscow and Paris, offer different planning advantages and challenges. GIS technologies can enhance understanding and management of these layouts.

  • Optimization of Major Roads: In cities like Moscow, where streets radiate from a central point, GIS can help optimize traffic flow around major intersections and radial routes. This analysis aids in improving connectivity between different parts of the city and managing traffic congestion (Talen, 2016).
  • Historical and Cultural Preservation: Radial patterns often reflect historical urban development. GIS can be employed to model historical growth and plan for contemporary needs while preserving cultural heritage. In Paris, for instance, the complex radial network overlays historical layers with modern infrastructure, which can be managed effectively through GIS-based scenario modeling (Al-Kodmany, 2018).

2. Topographical Influence and Environmental Integration

2.1. Adapting to Natural Landscapes

Cities with irregular street patterns often need to adapt their infrastructure to natural topography. GIS technologies facilitate this adaptation by providing insights into how geographical features impact urban development.

  • Environmental Sensitivity: GIS tools can analyze the interaction between urban development and natural landscapes. For example, Cape Town’s street network incorporates large open spaces due to its mountainous terrain. GIS can model the environmental impacts of new developments and ensure that urban expansion is sustainable (Gibson, 2004).
  • Sustainable Urban Design: GIS helps in planning green spaces and managing urban sprawl. For cities like Sydney, GIS can be used to enhance the integration of green infrastructure and manage urban growth in a way that minimizes environmental impact (Brabham, 2013). This includes planning for parks, green belts, and sustainable drainage systems.

3. Enhancing Urban Planning and Development

3.1. Data-Driven Decision Making

GIS provides valuable data that supports informed decision-making in urban planning. This includes:

  • Infrastructure Development: Identifying optimal locations for new infrastructure projects is crucial for urban growth. In cities like Kuala Lumpur, which exhibit a mix of grid and organic patterns, GIS can help plan new roads and public facilities by analyzing existing infrastructure and predicting future needs (Longley et al., 2015).
  • Scenario Modeling: GIS enables the simulation of various planning scenarios to assess their impacts on traffic, land use, and the environment. This is particularly useful for rapidly developing cities like Dubai, where GIS can model different development strategies and their potential outcomes (Cheng et al., 2019).
  • Emergency Response Planning: Effective urban planning also involves preparing for emergencies. GIS can help model emergency response times and optimize the placement of emergency services to ensure swift access during crises.

4. Conclusion

GIS technologies offer powerful tools for analyzing and optimizing street networks, enhancing urban planning, and fostering sustainable development. By leveraging GIS to understand and improve street network configurations, cities can enhance infrastructure, improve traffic management, and create more livable urban environments.

The Influence of Street Network Configurations on Urban Planning and Population Dynamics

Configurations of street networks in densely populated cities

By Shahabuddin Amerudin

Introduction

Urban planning is a multifaceted discipline that orchestrates the development and organization of cities to optimize functionality, sustainability, and livability. A fundamental component of urban planning is the design and configuration of street networks, which serve as the skeletal framework of urban spaces. Street networks not only facilitate transportation and connectivity but also profoundly influence land use patterns, economic activities, social interactions, and environmental outcomes (Hillier & Hanson, 1984; Marshall, 2005). The interplay between street network configurations and city populations is intricate, reflecting historical contexts, geographical constraints, and evolving urban development philosophies. This article delves into the diverse street network patterns observed in cities across the globe and examines how these configurations relate to urban planning strategies and population dynamics.

The Essence of Street Network Configurations

Street networks are the veins and arteries of urban landscapes, determining how people, goods, and services move within a city. They shape the physical structure of urban areas, influencing everything from residential and commercial development to public spaces and environmental quality (Batty, 2007). The design of these networks is influenced by various factors, including topography, historical evolution, cultural norms, economic imperatives, and technological advancements (Southworth & Ben-Joseph, 2003). Broadly, street network configurations can be categorized into four primary patterns: grid, radial, organic, and mixed systems. Each pattern embodies distinct urban planning philosophies and responds differently to population pressures and urban growth (Jacobs, 1961).

Grid Patterns: Order and Efficiency

Grid patterns are characterized by perpendicular intersections creating a network of uniformly sized blocks. This configuration promotes simplicity, regularity, and ease of navigation (Alexander, 1965). Historically, grid systems have been employed since ancient times, notably in Roman city planning and later in the design of modern American cities (Gallion & Eisner, 1986). The grid layout reflects a desire for orderliness and rationality, facilitating straightforward land division and development.

Vancouver’s urban landscape showcases a classic grid pattern, particularly evident in its downtown area. The city’s planners adopted this layout in the late 19th and early 20th centuries to accommodate rapid population growth and economic expansion (GVRD Planning Department, 1996). The grid system has enabled efficient land use and has supported high-density development, catering to a diverse and growing population (Berelowitz, 2005). The uniform street layout simplifies transportation planning and has facilitated the implementation of comprehensive public transit systems, cycling networks, and pedestrian-friendly spaces (Punter, 2003).

Beijing presents a historical example of grid planning, deeply rooted in traditional Chinese urban design principles emphasizing harmony and symmetry. The city’s central axis and orthogonal street layout date back to ancient times, centered around the Forbidden City (Sit, 1995). The grid has accommodated Beijing’s massive population by organizing residential, commercial, and administrative zones systematically (Zhao & Lu, 2020). This structure has supported extensive public transportation networks, including buses and subways, essential for managing the city’s high population density (Ding & Zhao, 2014).

Radial Patterns: Centrality and Connectivity

Radial patterns feature streets emanating from a central point, often intersected by concentric rings. This design emphasizes centrality, with the core serving as a focal point for administrative, commercial, or cultural activities (Mumford, 1961). Radial layouts are common in cities with historical centers, where growth has radiated outward over time (Kostof, 1991).

Moscow’s street network epitomizes the radial pattern, centered around the Kremlin. The city’s development over centuries has produced a series of concentric ring roads intersected by radial avenues, facilitating movement between the periphery and the center (Zolotov, 2003). This structure supports centralized governance and administration while accommodating a substantial and expanding population (Grigor’ev & Romanova, 2018). The radial network enhances connectivity to central amenities and services but can also concentrate traffic congestion toward the core (Fourie & Snowball, 2017).

Paris combines radial and organic patterns, with avenues extending from central landmarks such as the Arc de Triomphe and intersecting irregular medieval streets. The city’s radial avenues, many of which were redesigned during Baron Haussmann’s 19th-century renovations, improve accessibility to the city’s heart and distribute population density effectively across different arrondissements (Sutcliffe, 1981). This network supports efficient public transportation and contributes to Paris’s iconic urban aesthetics (Norberg-Schulz, 1979).

Organic Patterns: Adaptation and Complexity

Organic street patterns evolve naturally over time without a predetermined plan, often adapting to geographical features, historical land uses, and social dynamics (Lynch, 1960). These networks are typically irregular, with winding streets and varied block sizes, reflecting the incremental and unplanned growth of a city (Hillier, 1996).

Sydney’s street network exhibits organic characteristics, particularly in older districts like The Rocks. The city’s development around its harbor and rugged terrain has produced a complex and irregular street layout (Spearritt, 2000). This pattern reflects adaptation to the natural landscape and historical growth patterns, resulting in diverse urban forms and densities (Murphy & Watson, 1997). While charming and historically rich, Sydney’s organic streets can pose challenges for modern transportation and infrastructure planning (Davison & DeMarco, 2007).

Cape Town’s street configuration combines organic development with some planned elements, shaped significantly by its mountainous surroundings and coastal location (Bickford-Smith, 1995). The organic layout accommodates the city’s varied topography and has resulted in unique neighborhoods with distinct identities (Western, 1981). Managing infrastructure and service delivery across such a diverse landscape requires adaptive and context-sensitive urban planning approaches (Freund, 2010).

Mixed Patterns: Integration and Evolution

Mixed street patterns incorporate elements from grid, radial, and organic systems, often resulting from layered historical developments and contemporary planning interventions (AlSayyad, 2001). These configurations reflect the complex evolution of cities adapting to changing needs, technologies, and populations (Jürgens & Donaldson, 2012).

Dubai’s street network exemplifies a mixed pattern, combining structured grids in newer developments like Downtown Dubai with more organic layouts in older districts (Elsheshtawy, 2010). The city’s rapid transformation from a modest trading port to a global metropolis has necessitated diverse planning approaches (Davis, 2006). The integration of extensive highways, planned residential communities, and organically evolved neighborhoods accommodates a rapidly growing and multicultural population while supporting economic diversification (AlAwadhi & Bryant, 2012).

Kuala Lumpur’s street network reflects its evolution from a colonial-era settlement to a modern capital (King, 2008). The city features grid-like patterns in planned urban centers alongside organic streets in older and suburban areas (Goh, 1991). This mixed configuration supports varied population densities and land uses, balancing commercial growth with residential needs (Ho & Lim, 2009). The city’s planners face the ongoing challenge of integrating transportation and infrastructure across these diverse urban fabrics (Goldman, 2011).

Discussion

The analysis of street network configurations reveals the profound impact these patterns have on urban planning and population dynamics. Each type of street network—grid, radial, organic, and mixed—affects how cities develop and function in distinct ways, reflecting both historical and contemporary planning practices.

Cities like Vancouver and Beijing showcase how grid patterns facilitate efficient land use and transportation. The regularity of grid layouts simplifies navigation, supports high-density development, and integrates well with modern infrastructure systems (GVRD Planning Department, 1996; Zhao & Lu, 2020). This predictability in design can be advantageous for urban planning, especially in rapidly growing cities. However, the uniformity of grid patterns can sometimes lead to monotonous urban environments and may not always adapt well to geographical constraints.

The radial layouts observed in cities such as Moscow and Paris emphasize centrality and connectivity, centering economic and administrative functions around a core (Zolotov, 2003; Sutcliffe, 1981). This configuration often supports vibrant central districts but can also concentrate traffic and urban pressures toward the center. Radial patterns enhance accessibility to central amenities but may pose challenges for managing traffic congestion and sprawl (Fourie & Snowball, 2017).

Sydney and Cape Town illustrate how organic street patterns evolve in response to natural landscapes and historical growth (Spearritt, 2000; Bickford-Smith, 1995). These configurations reflect a more adaptive and context-sensitive approach to urban development. While organic patterns can create unique and vibrant urban spaces, they can also result in irregular infrastructure and service delivery challenges. The lack of uniformity can complicate planning and navigation, requiring more flexible and innovative approaches to urban management (Murphy & Watson, 1997; Freund, 2010).

The mixed street networks seen in Dubai and Kuala Lumpur represent a synthesis of different planning approaches, accommodating both historical growth and contemporary needs (Elsheshtawy, 2010; King, 2008). These configurations often arise from the layering of various urban planning phases and can offer a balance between the efficiency of grid systems and the adaptability of organic patterns. However, managing such diverse layouts requires careful coordination to address the varying demands of different urban areas (AlAwadhi & Bryant, 2012; Goldman, 2011).

Conclusion

Street network configurations are fundamental to urban planning, shaping how cities grow, function, and interact with their populations. Grid patterns offer efficiency and clarity, radial patterns emphasize centrality and connectivity, organic patterns adapt to historical and geographical contexts, and mixed patterns integrate multiple planning strategies. Understanding these configurations provides valuable insights for urban planners and policymakers aiming to design cities that are functional, livable, and resilient.

Each network type has its strengths and limitations, and the choice of configuration often reflects a city’s historical evolution, geographical constraints, and planning philosophy. As cities continue to grow and evolve, there is an increasing need for adaptive and integrative planning approaches that address the complexities of modern urban environments. Future research should focus on how emerging technologies and innovative planning practices can enhance the functionality and sustainability of various street network patterns, ensuring that urban areas can meet the demands of dynamic populations and evolving urban landscapes.

Boids Algorithm for Simulating Crowd Movement in Urban Planning and Disaster Management

boids simulation

By Shahabuddin Amerudin

Abstract

The ability to accurately simulate crowd movement during emergencies is critical in urban planning and disaster management, as it helps design effective evacuation strategies and minimizes the potential for casualties. The Boids algorithm, initially developed to replicate the flocking behavior of birds, provides a versatile framework for modeling the dynamics of crowd movement. This paper explores the application of the Boids algorithm in simulating crowd movement during emergency situations such as floods, analyzing its strengths and limitations. Supported by a comprehensive literature review, this discussion examines the algorithm’s effectiveness in various scenarios, its potential for integration with other models, and its implications for the future of disaster management and urban planning.

1. Introduction

In densely populated urban environments, emergency situations like natural disasters, industrial accidents, or large-scale public events necessitate the swift and efficient evacuation of large numbers of people. Understanding how crowds behave in such situations is crucial for designing evacuation plans that minimize risks and ensure the safety of the population. Traditional methods of crowd simulation often fall short of capturing the complex and dynamic nature of human behavior under stress. In contrast, agent-based models, particularly those based on the Boids algorithm, offer a more flexible and scalable approach to simulating crowd dynamics (Reynolds, 1987).

The Boids algorithm, created by Craig Reynolds in 1986, was originally designed to simulate the flocking behavior of birds. The principles underlying this algorithm—cohesion, separation, and alignment—can be adapted to model the movement of human crowds. These principles allow for the emergence of complex group behaviors from simple individual rules, making the Boids algorithm an effective tool for simulating the dynamics of crowds in evacuation scenarios (Reynolds, 1987). This paper will explore the application of the Boids algorithm in various emergency scenarios, including confined spaces, obstacle avoidance, and large-scale evacuations, while also discussing the advantages and limitations of this approach.

2. Theoretical Framework of the Boids Algorithm

The Boids algorithm operates on three fundamental principles that govern the movement of individual agents, known as “boids,” within a simulated environment:

  • Cohesion: This principle directs each boid to move toward the average position of its neighbors. In a crowd simulation, cohesion ensures that individuals tend to stay together, forming a cohesive group as they move through a space.
  • Separation: Separation prevents boids from crowding too closely together by making them steer away from each other if they get too close. In the context of human crowds, this principle helps simulate how individuals maintain personal space and avoid collisions, even in densely populated areas.
  • Alignment: Alignment causes each boid to adjust its velocity to match the average velocity of its neighbors. This principle is crucial for simulating how individuals in a crowd synchronize their movement, such as aligning their direction and speed with others around them to maintain group coherence.

These three rules enable the simulation of complex group dynamics that resemble real-world crowd behavior. The simplicity of these rules, combined with their ability to generate realistic emergent behaviors, makes the Boids algorithm a powerful tool for modeling crowd movement in a variety of scenarios (Reynolds, 1987).

3. Literature Review

3.1. Agent-Based Modeling in Crowd Simulation

Agent-based modeling (ABM) has become increasingly popular in the study of crowd dynamics due to its ability to simulate the interactions of individual agents within a system. Unlike traditional equation-based models, ABM allows for the modeling of heterogeneous agents, each with its own set of behaviors and decision-making processes (Bonabeau, 2002). This capability is particularly important in the context of crowd simulations, where individual behaviors can vary widely depending on factors such as age, physical condition, and emotional state.

Numerous studies have demonstrated the effectiveness of ABM in simulating crowd movement during emergency evacuations. Helbing et al. (2000) utilized an agent-based approach to simulate escape panic, highlighting how simple local rules can lead to complex, emergent phenomena such as bottlenecks and lane formation. Their work underscores the importance of considering individual behaviors and interactions when modeling crowd dynamics, an approach that aligns well with the principles of the Boids algorithm.

3.2. The Boids Algorithm in Crowd Simulation

The application of the Boids algorithm in crowd simulation has been explored in various studies, demonstrating its effectiveness in modeling different types of crowd behavior. For example, Moussaïd et al. (2011) applied the Boids algorithm to simulate pedestrian movement in crowded environments. Their study found that the algorithm could successfully replicate common crowd behaviors, such as the formation of lanes in bidirectional flow and the avoidance of collisions. This ability to model realistic crowd dynamics makes the Boids algorithm a valuable tool for urban planners and disaster management professionals.

Kukla and Mastorakis (2016) further extended the application of the Boids algorithm to simulate crowd evacuation in emergency situations. Their research demonstrated that the algorithm could be used to model how individuals navigate through confined spaces, such as narrow corridors or staircases, during an evacuation. The study also highlighted the algorithm’s potential for simulating the impact of obstacles on crowd movement, which is critical for designing effective evacuation plans.

3.3. Integration with Other Models

While the Boids algorithm is effective in simulating basic crowd dynamics, it may need to be integrated with other models to fully capture the complexity of human behavior in emergency situations. For example, Lovreglio et al. (2014) developed an evacuation decision model that combines the Boids algorithm with a psychological model of perceived risk and social influence. This integrated approach allows for the simulation of more nuanced behaviors, such as the tendency of individuals to follow others or to hesitate when faced with uncertain conditions. Such integrations are essential for creating more accurate and realistic simulations that can inform disaster management strategies.

4. Applications in Evacuation Simulation

The Boids algorithm’s principles of cohesion, separation, and alignment have been successfully applied to various evacuation scenarios, demonstrating its versatility and effectiveness in urban planning and disaster management. This section explores specific applications of the algorithm in simulating crowd movement through confined spaces, responding to obstacles, and managing large-scale evacuations.

4.1. Movement through Confined Spaces

Emergency situations often require individuals to navigate confined spaces, such as narrow corridors, staircases, or doorways, where the risk of congestion and bottlenecks is high. The Boids algorithm can simulate how individuals adjust their movement to avoid crowding while maintaining a steady flow through these spaces. This capability is particularly important in scenarios where rapid evacuation is critical, such as during a fire or a flood.

Helbing et al. (2000) demonstrated that agent-based models, including those based on the Boids algorithm, could effectively replicate the spontaneous formation of lanes and patterns seen in real-life evacuations. Their research showed that when individuals are forced to move through narrow corridors, they tend to form lanes that allow for a more efficient flow of movement. This behavior can be simulated using the Boids algorithm’s cohesion and alignment principles, which encourage individuals to follow others while maintaining a safe distance.

The ability to simulate movement through confined spaces is crucial for optimizing the design of buildings and public spaces. For example, architects and urban planners can use these simulations to identify potential bottlenecks in building layouts and design more efficient exit routes. By incorporating the Boids algorithm into the design process, it is possible to create environments that facilitate safer and more efficient evacuations during emergencies.

4.2. Response to Obstacles

Urban environments often contain obstacles that can impede crowd movement during evacuations. These obstacles may include physical barriers, such as walls or debris, as well as dynamic hazards, such as fires or floodwaters. The Boids algorithm can be adapted to account for such obstacles, allowing agents to dynamically reroute and avoid hazardous areas.

Studies have shown that this adaptability is key to understanding how crowds react to changes in their environment. For example, Lovreglio et al. (2014) used the Boids algorithm to simulate the impact of obstacles on crowd movement during an evacuation. Their research found that individuals tend to avoid obstacles by following alternative routes, even if these routes are longer or more difficult to navigate. This behavior can be simulated using the algorithm’s separation principle, which encourages agents to steer away from obstacles while maintaining cohesion with the rest of the group.

Floods pose significant challenges for crowd movement and evacuation, especially in urban areas where rapidly rising water levels can create unpredictable hazards and severely limit escape routes. The Boids algorithm, which models crowd behavior based on principles of cohesion, separation, and alignment, can be adapted to simulate how people respond to such dynamic and dangerous conditions. Researchers have applied agent-based models, including the Boids algorithm, to simulate crowd behavior during flood evacuations. For example, Tang and Ren (2012) used an extended Boids model to simulate the evacuation of a small town during a flash flood, incorporating real-time data on water levels and flow rates. This approach allowed the simulation to reflect how individuals might change their paths as conditions worsened, highlighting the critical importance of early warning systems and pre-planned evacuation routes to prevent people from becoming trapped by rapidly rising water.

By using the Boids algorithm to model crowd movement during floods, urban planners and disaster management professionals can identify vulnerable areas and develop strategies to mitigate risks. Simulations can pinpoint potential bottlenecks where floodwaters could impede evacuation, enabling authorities to reinforce these areas or create alternative routes. Additionally, the ability to incorporate obstacles, such as rising water or debris, into these simulations allows for the development of more effective and adaptable evacuation plans that enhance the overall safety and efficiency of emergency responses.

4.3. Traffic Control and Large-Scale Evacuations

Beyond individual buildings and confined spaces, the Boids algorithm can be extended to simulate larger-scale evacuations involving urban traffic and mass gatherings. This application is particularly relevant for managing evacuations during large public events or in response to widespread disasters, such as earthquakes or terrorist attacks.

Zhang et al. (2019) applied the Boids algorithm to simulate large-scale evacuations in urban areas, considering the interaction between pedestrian and vehicular traffic. Their study highlighted the importance of coordinated traffic management and the strategic placement of emergency services to facilitate smooth evacuations. The Boids algorithm’s principles of cohesion, separation, and alignment can be used to simulate how pedestrians and vehicles interact during an evacuation, allowing planners to identify potential conflicts and optimize traffic flow.

For example, during a large public event, the Boids algorithm can be used to simulate the movement of crowds as they exit the venue and navigate through the surrounding streets. By incorporating factors such as traffic signals, road closures, and the availability of public transportation, the simulation can provide valuable insights into how to manage the flow of people and vehicles during an evacuation. This information can be used to design more effective traffic management strategies that minimize congestion and ensure the safety of both pedestrians and drivers.

5. Advantages and Limitations

While the Boids algorithm offers numerous advantages for simulating crowd movement and evacuation scenarios, it also has certain limitations that must be considered.

5.1. Advantages

The primary advantage of the Boids algorithm is its modularity and scalability. The algorithm can be easily adjusted to simulate different types of crowds and scenarios, making it a versatile tool for urban planners and emergency managers. Its ability to handle large groups of agents makes it suitable for simulating mass gatherings or large-scale evacuations, where the behavior of the crowd can significantly impact the outcome of the evacuation (Moussaïd et al., 2011).

Another advantage of the Boids algorithm is its ability to generate realistic emergent behaviors from simple individual rules. The principles of cohesion, separation, and alignment allow for the simulation of complex group dynamics that closely resemble real-world crowd behavior. This capability is particularly important for simulating emergency evacuations, where the behavior of the crowd can be unpredictable and difficult to model using traditional methods.

5.2. Limitations

However, the simplicity of the Boids algorithm also presents certain limitations. While effective for simulating general crowd dynamics, the algorithm may not fully capture the complex psychological and emotional factors that influence human behavior during emergencies. For example, the algorithm assumes that all agents behave rationally and have similar goals, which may not always be the case in real-world scenarios. In reality, individuals may act irrationally or unpredictably due to factors such as panic, fear, or the influence of others (Wolfram, 2002).

Additionally, the Boids algorithm does not account for the impact of individual characteristics, such as age, physical condition, or familiarity with the environment, on crowd behavior. These factors can significantly influence how individuals respond to an emergency situation and should be considered when simulating crowd movement. To address these limitations, the Boids algorithm may need to be integrated with other models that account for psychological and demographic factors.

6. Future Directions

As urban environments continue to grow and become more complex, the need for accurate and reliable crowd simulation tools will only increase. The Boids algorithm, with its ability to simulate large-scale evacuations and complex crowd dynamics, will likely play a central role in the future of urban planning and disaster management. However, to fully realize its potential, further research is needed to address the algorithm’s limitations and enhance its applicability to a wider range of scenarios.

6.1. Integration with Psychological Models

One promising direction for future research is the integration of the Boids algorithm with psychological models that account for the impact of emotions, social influence, and decision-making processes on crowd behavior. By incorporating these factors into the simulation, it may be possible to create more realistic and accurate models of crowd movement during emergencies.

For example, researchers could develop a hybrid model that combines the Boids algorithm with a psychological model of panic behavior. This model could simulate how individuals respond to fear and uncertainty during an evacuation, such as hesitating at exits or following others without a clear plan. Such a model would provide valuable insights into how panic spreads through a crowd and how it impacts the overall efficiency of the evacuation.

6.2. Incorporation of Real-Time Data

Another promising direction for future research is the incorporation of real-time data into the Boids algorithm. Advances in sensor technology and data analytics have made it possible to collect and analyze large amounts of data on crowd movement in real time. By integrating this data into the simulation, it may be possible to create dynamic models that can adjust to changing conditions and provide real-time feedback to emergency managers.

For example, during a large public event, sensors could be used to monitor crowd density and movement in real time. This data could be fed into the Boids algorithm to simulate how the crowd is likely to behave in the event of an emergency. The simulation could then be used to guide traffic management decisions, such as opening or closing certain exits or redirecting pedestrians to less crowded areas.

6.3. Application to New Urban Challenges

Finally, future research should explore the application of the Boids algorithm to new and emerging challenges in urban planning and disaster management. For example, the algorithm could be used to simulate crowd movement in response to new types of threats, such as cyber-attacks on critical infrastructure or the spread of infectious diseases.

In the case of a pandemic, the Boids algorithm could be used to simulate how individuals move through public spaces while maintaining social distancing. This information could be used to design public spaces that minimize the risk of disease transmission and ensure the safety of the population. Similarly, the algorithm could be used to simulate the impact of a cyber-attack on transportation systems, helping to identify potential vulnerabilities and develop strategies for mitigating the impact of such attacks.

7. Conclusion

The Boids algorithm offers a robust and flexible framework for simulating crowd movement and evacuation scenarios in urban environments. Its principles of cohesion, separation, and alignment enable the realistic modeling of group behavior, making it a valuable tool for urban planners and disaster management professionals. The application of the Boids algorithm in flood scenarios, as well as in other emergency situations, demonstrates its potential to provide critical insights into evacuation planning and risk mitigation.

While the algorithm has certain limitations, such as its simplified representation of individual behavior and lack of psychological considerations, it remains a powerful tool due to its modularity and scalability. The ability to integrate real-time data and psychological models into the Boids framework offers promising avenues for future research, which could lead to more accurate and effective simulations of crowd behavior under various emergency conditions.

By exploring the application of the Boids algorithm in emergency evacuations and other urban challenges, this paper underscores the importance of continued research and development in this area. Future studies should focus on addressing the algorithm’s limitations and expanding its applicability to a broader range of scenarios, ensuring that urban planners and disaster management professionals are well-equipped to handle the complexities of modern urban environments.

Ciri-Ciri Pelajar Cemerlang dalam Projek Sarjana Muda

pelajar universiti

Oleh Shahabuddin Amerudin

Projek Sarjana Muda (PSM) merupakan langkah terakhir dan paling kritikal dalam perjalanan akademik seorang pelajar di peringkat ijazah sarjana muda di universiti. Ia adalah satu projek yang bukan sahaja menuntut pelajar untuk menerapkan segala pengetahuan yang telah dipelajari, tetapi juga memerlukan pelajar untuk menunjukkan pelbagai ciri yang mampu menjamin kejayaan mereka. Dalam artikel ini, kita akan meneliti ciri-ciri utama yang diperlukan oleh pelajar untuk berjaya dalam PSM serta bagaimana ciri-ciri ini boleh dioptimumkan untuk menghasilkan hasil kerja yang cemerlang.

1. Rajin dan Bijak: Dua Sisi yang Sama

Rajin adalah asas kejayaan dalam PSM. Pelajar yang rajin sentiasa berusaha untuk memahami topik kajian mereka dengan lebih mendalam, menyelesaikan tugasan yang diberikan tepat pada masanya, dan konsisten dalam kerja mereka. Namun, rajin sahaja tidak mencukupi jika tidak digandingkan dengan kebijaksanaan dalam menguruskan masa, sumber, dan tenaga. Bijak (smart) dalam konteks ini bermaksud pelajar mampu membuat keputusan yang tepat, mengutamakan tugas yang lebih penting, dan menggunakan masa dengan lebih efektif. Pelajar yang bijak mungkin tidak perlu bekerja keras sepanjang masa, tetapi mereka tahu bila dan bagaimana untuk memberi fokus kepada perkara yang benar-benar penting.

2. Ingin Tahu dan Rajin Bertanya: Pintu Kepada Ilmu Baru

Sifat ingin tahu adalah pemacu utama kepada pembelajaran yang mendalam. Pelajar yang mempunyai rasa ingin tahu yang tinggi akan lebih cenderung untuk menyelidik sesuatu topik dengan lebih mendalam dan sentiasa mencari jawapan kepada soalan-soalan yang timbul dalam fikiran mereka. Sifat ini, apabila digabungkan dengan kecenderungan untuk bertanya, akan membuka lebih banyak ruang pembelajaran. Rajin bertanya bukan sahaja membantu pelajar untuk memahami dengan lebih baik, tetapi juga memperlihatkan kesungguhan mereka kepada penyelia dan panel penilai.

3. Disiplin dan Pengurusan Masa yang Teratur

Disiplin adalah kunci untuk memastikan semua tugasan dalam PSM diselesaikan tepat pada masanya. Tanpa disiplin, pelajar mungkin terjebak dalam sikap bertangguh, yang akhirnya boleh menjejaskan kualiti hasil kerja. Pengurusan masa yang teratur pula membolehkan pelajar membahagikan masa mereka dengan bijak antara kajian, penulisan, dan tugas-tugas lain. Pelajar yang berdisiplin dan bijak menguruskan masa mereka akan lebih tenang dan bersedia menghadapi cabaran yang datang, termasuk saat-saat genting seperti pembentangan akhir.

4. Kreativiti: Membezakan Antara Kajian Biasa dan Luar Biasa

Kreativiti adalah satu lagi elemen penting dalam PSM. Dalam penyelidikan, kreativiti membantu pelajar mencari pendekatan baru dalam menyelesaikan masalah, menghasilkan idea-idea inovatif, dan menyampaikan hasil kajian dengan cara yang menarik. Kreativiti boleh diaplikasikan dalam pelbagai aspek PSM, sama ada dalam merangka metodologi kajian, menganalisis data, atau menyusun laporan akhir. Pelajar yang kreatif mampu menghasilkan kajian yang bukan sahaja memenuhi syarat akademik tetapi juga memberikan sumbangan bermakna kepada bidang mereka.

5. Adaptabiliti: Keupayaan untuk Menyesuaikan Diri dengan Perubahan

Dalam perjalanan melaksanakan PSM, perubahan dan cabaran yang tidak dijangka adalah perkara biasa. Kemampuan untuk beradaptasi dengan perubahan ini adalah ciri yang sangat diperlukan. Pelajar yang adaptif mampu mengubah strategi mereka dengan cepat apabila berdepan dengan halangan, dan mencari jalan alternatif untuk mencapai matlamat mereka. Ini memastikan bahawa projek mereka terus berjalan walaupun terdapat halangan yang tidak diduga.

6. Kesabaran dan Ketekunan: Mengatasi Cabaran dengan Tenang

Kesabaran adalah perlu dalam setiap fasa PSM, terutama ketika berdepan dengan kegagalan atau keputusan yang tidak memuaskan. Ketekunan pula adalah kemampuan untuk terus berusaha dan tidak mudah berputus asa. Dalam dunia penyelidikan, kegagalan adalah sebahagian daripada proses pembelajaran. Pelajar yang sabar dan tekun akan lebih berdaya tahan dalam menghadapi cabaran, dan mereka akan bangkit dengan lebih kuat selepas setiap kegagalan.

7. Kemahiran Komunikasi yang Berkesan: Menyampaikan Idea dengan Jelas

Komunikasi yang berkesan adalah penting dalam PSM, terutama ketika berinteraksi dengan penyelia, rakan sebaya, dan panel penilai. Pelajar perlu mampu menyampaikan idea mereka dengan jelas dan meyakinkan, sama ada secara lisan atau bertulis. Selain itu, kemahiran mendengar dan menerima maklum balas juga adalah penting, kerana ia membantu pelajar untuk memperbaiki kelemahan dalam kajian mereka.

8. Kemahiran Kerja Berpasukan: Belajar Bersama, Berjaya Bersama

Walaupun PSM selalunya merupakan tugasan individu, pelajar tidak boleh mengabaikan kepentingan kemahiran kerja berpasukan. Dalam proses pengumpulan data, analisis, dan perbincangan, pelajar sering kali perlu bekerjasama dengan orang lain. Kemampuan untuk bekerja dalam kumpulan membantu pelajar mendapatkan perspektif yang berbeza, serta menyumbang kepada penyelesaian masalah yang lebih kreatif.

9. Kemampuan Mencari dan Mengurus Sumber: Mengoptimumkan Penggunaan Sumber

Satu lagi ciri penting ialah kebolehan untuk mencari, menilai, dan menguruskan sumber dengan berkesan. Dalam PSM, pelajar perlu menggunakan pelbagai sumber seperti bahan rujukan, data, perisian, dan peralatan makmal. Pelajar yang proaktif dalam mencari sumber yang berkualiti dan bijak dalam menguruskan penggunaannya akan lebih mudah mencapai kejayaan dalam projek mereka.

Kesimpulan

Kejayaan dalam Projek Sarjana Muda bukanlah hasil daripada satu faktor tunggal, tetapi merupakan gabungan pelbagai ciri dan sikap yang diterapkan oleh pelajar sepanjang proses penyelidikan. Dengan menggabungkan sifat-sifat rajin, bijak, kreatif, dan berdisiplin, serta kemampuan untuk beradaptasi, berkomunikasi dengan baik, dan bekerja dalam pasukan, pelajar bukan sahaja mampu menghasilkan kajian yang cemerlang tetapi juga mempersiapkan diri untuk cabaran-cabaran yang bakal ditempuhi dalam dunia profesional kelak. Setiap pelajar mempunyai potensi untuk berjaya, dan kejayaan itu terletak di tangan mereka sendiri.

Development of a Web-Based Application for Matching Students with Supervisors Using a Weighted Scoring Algorithm

Student-Supervisor Matching Application

By Shahabuddin Amerudin

Abstract

This paper presents the development of a web-based application designed to automate the matching process between students and supervisors. The application leverages a weighted scoring algorithm to evaluate compatibility based on various academic and professional criteria. The system aims to improve the efficiency and fairness of assigning supervisors by using a data-driven approach. The implementation involves PHP for server-side logic, JavaScript for client-side interaction, and JSON for data storage. This paper provides an overview of the development process, details of the algorithm, and examples demonstrating the application’s functionality.

Introduction

The process of assigning students to supervisors in academic institutions is often subjective and time-consuming. Traditional methods rely heavily on manual matching, which may not always be optimal. This paper proposes a web-based application that uses a weighted scoring algorithm to facilitate an objective and efficient matching process. The application considers various factors such as programming skills, database management, GIS knowledge, spatial analysis expertise, and project focus alignment.

Application Architecture

The application is built using a combination of HTML, JavaScript, PHP, and JSON. The front end is developed using HTML and JavaScript, while PHP handles the server-side logic. JSON files are used to store data related to students, supervisors, and their matching results. The core functionality of the application is centered around the matching algorithm, which processes the data and outputs a match score for each student-supervisor pair.

Algorithm Description

The matching algorithm is designed to evaluate the compatibility between students and supervisors based on a weighted scoring system. The algorithm considers the following criteria:

  • Programming Skills
  • Database Management Skills
  • GIS Knowledge
  • Spatial Analysis Expertise
  • Management Skills
  • Project Focus

Each criterion is assigned a weight that reflects its importance in the overall match. The algorithm then calculates a score based on the difference between the student’s and the supervisor’s ratings in each criterion. The formula used to calculate the score for each criterion is as follows:

Score=W×(10−∣Student_Rating−Supervisor_Rating∣)

where:

  • WW is the weight assigned to the criterion,
  • Student_Rating is the student’s rating for the criterion (on a scale of 1 to 10),
  • Supervisor_Rating is the supervisor’s rating for the criterion (on a scale of 1 to 10).

The total score for each student-supervisor pair is the sum of the scores across all criteria. An additional score is awarded if the student’s project focus aligns with the supervisor’s area of expertise.

Example

Consider a scenario where a student named Wahida is to be matched with a supervisor. Wahida’s ratings and the ratings of three potential supervisors (ALMS, MRM, and NY) are shown below:

CriteriaWahida’s RatingALMS’s RatingMRM’s RatingNY’s Rating
Programming8768
Database7876
GIS6687
Spatial Analysis7778
Management5655
Project FocusGISGISManagementGIS

The weights for each criterion are as follows:

  • Programming: 1.5
  • Database: 1.2
  • GIS: 1.0
  • Spatial Analysis: 1.0
  • Management: 0.8
  • Project Focus: 2.0

Based on these calculations, Wahida would be matched with ALMS, who has the highest score of 48.2.

Implementation and Results

The algorithm was implemented in PHP, with the data stored in JSON format. The application includes an interface where students and supervisors can submit their survey data, which is then processed to generate the matches. The results are stored in a matches.json file and can be viewed through the application’s interface.

Despite the careful design, initial tests revealed issues with the loop logic, leading to repeated matches and the failure to process new data entries. These issues were debugged by examining the debug_students.json and debug_supervisors.json files, which were correctly updated, while the matches.json file was not. Further refinements to the loop and file writing processes resolved these issues.

Conclusion

This paper presents a systematic approach to matching students with supervisors using a weighted scoring algorithm. The implementation demonstrates the feasibility of using web-based applications to enhance the fairness and efficiency of the matching process in academic institutions. Future work will involve refining the algorithm to handle more complex scenarios and integrating machine learning techniques to improve matching accuracy.
