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.
