The increasing integration of information and communication technology in education has accelerated the transformation from conventional classroom-based learning to digital platforms. This study presents the design and development of a web-based online examination system for the Faculty of Engineering at Universitas Jabal Ghafur. The system aims to provide an effective and efficient alternative to traditional examinations, ensuring that assessments can be conducted anytime and anywhere without requiring physical meetings. The research applies a mixed methodological approach, combining theoretical review and field research to analyze operational needs and user expectations. The platform is built using the CodeIgniter framework, PHP programming language, and MySQL database, and it integrates core academic functions such as course management, lecturer and student data, class scheduling, exam creation, and learning material distribution. System modeling employs both Entity Relationship Diagram (ERD) and Data Flow Diagram (DFD) to ensure structured and maintainable development. Implementation results show significant improvements in time efficiency, resource optimization, and administrative cost reduction. Beyond improving examination management, this system supports a more flexible, accessible, and technology-driven learning environment that aligns with the ongoing digital transformation in higher education.

Rural development has become a strategic pillar in Indonesia’s national agenda following the enactment of Village Law No. 6 of 2014, which empowers villages to manage resources and finances independently. Despite the significant increase in village fund allocations, challenges such as limited administrative capacity, lack of transparency, and data fragmentation persist, particularly in regions like Glumpang Baro Sub-District. This study developed a Geographic Information System (GIS) designed to map and monitor infrastructure projects funded by the village fund program. The system was constructed using the waterfall development model, employing PHP as the main programming language, MySQL as the database management system, and Google Maps API for spatial visualization. Data were collected through observation, documentation, and literature analysis to ensure system relevance and accuracy. The resulting web-based GIS enables centralized storage, real-time access, and transparent reporting of development activities for both administrators and the public. Empirical evaluation shows substantial efficiency improvements: operational costs decreased by 86%, data entry time by 80%, and workforce requirements by 40% compared to the previous manual approach. Beyond technical functionality, the system fosters participatory governance, accountability, and informed decision-making, providing a scalable model for digital transformation in local development management.

This study aimed to design and develop a website for the Student and Alumni Development Institute (LPKA) of Universitas Muhammadiyah Tasikmalaya as a digital service platform that integrates student and alumni activities, improves data management, and facilitates institutional communication. The project adopted the Research and Development (R&D) approach combined with the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The website was developed using WordPress due to its flexibility, scalability, and accessibility, supported by various plugins and custom features to meet institutional needs. Functionality testing through the Black Box method confirmed that all features—such as activity publication, scholarship announcements, report uploads, and discussion forums—operated correctly. Validation by software experts (84%), institutional staff (91.5%), and students/alumni (87.3%) demonstrated a high level of usability and system reliability. These findings indicate that the LPKA website effectively improves service efficiency, enhances transparency, and fosters stronger engagement between the university, students, and alumni. The system also serves as an example of how CMS-based development can be applied to support digital transformation in higher education. Future enhancements should include the integration of academic databases, the development of automated notification features, and the implementation of analytics tools for real-time monitoring to ensure long-term adaptability and institutional sustainability.

This study presents the design and implementation of an Internet of Things (IoT)-based monitoring system for indoor temperature and humidity using an ESP32 microcontroller and a DHT11 sensor, aimed at preventing wall mold growth in humid environments. The system continuously collects environmental data, transmits it to a Firebase Realtime Database, and visualizes it through a web-based dashboard accessible via desktop or mobile devices. The research was conducted through stages of hardware assembly, software programming, and real-time testing under varying indoor conditions. Experimental results showed that the DHT11 sensor recorded temperature errors ranging from −0.5°C to +0.8°C (1.21%–2.67%) and humidity errors between −2% and +3% RH (2.86%–7.50%), both within acceptable tolerance limits for environmental monitoring. The dashboard effectively displayed temperature and humidity trends, with clear visual cues indicating mold-risk conditions when humidity exceeded 70%. The system achieved a 98% data transmission success rate and operated reliably over continuous 24-hour testing. These findings confirm that the integration of DHT11, ESP32, and Firebase provides a low-cost, stable, and accurate platform for continuous environmental monitoring. The web dashboard enhances user engagement through intuitive visualization and real-time feedback. Future improvements are recommended, including higher-accuracy sensors, automatic notifications, and adaptive control mechanisms for ventilation or dehumidification. Overall, the system demonstrates that IoT-based monitoring can serve as an effective early warning tool for indoor mold prevention and environmental quality management in tropical climates.

This study presents the design and implementation of an Android-based Geographic Information System (GIS) for mapping souvenir shops in Aceh Province. The system was developed to address the lack of an integrated digital platform that provides reliable information about local souvenir vendors. Using GIS technology, the application enables users to view shop locations, product details, and navigation routes through interactive map visualization. The system development followed the Waterfall model, consisting of five main stages: requirements analysis, design, implementation, testing, and maintenance. Data were collected through literature review, field observation, and interviews. The application was built using Flutter for the mobile interface, PHP for the web server, and MySQL for database management, supported by the Google Maps API for spatial data integration. The resulting system features two main interfaces: a web-based dashboard for administrators and an Android application for end users. Testing showed improvements in efficiency, with reductions of approximately 43% in data entry time, 80% in report generation, and 40% in manpower requirements, along with an 86% reduction in annual operational costs. These findings demonstrate that the GIS-based system is effective, secure, and practical for managing and distributing information about Acehnese souvenir shops. Beyond its functional benefits, the application supports local tourism and strengthens small business visibility by providing accessible, location-based information.
