Development of an Android-Based Online Attendance System as a Learning Support Tool for Students in the Computer and Information Technology Education Study Program UNIMED

Student attendance is a critical component in managing academic activities, serving both administrative purposes and as a tool for evaluating the learning process. However, manual attendance systems commonly used in universities still suffer from several weaknesses, including proxy attendance, slow recording processes, and lack of integration with digital academic systems. This study aims to develop an Android-based online attendance system equipped with QR code scanning, GPS location validation, and face photo documentation to verify student presence. The system is designed to provide ease of use for both students and lecturers while improving the validity and efficiency of attendance data. The research employs a software engineering approach using the Waterfall development model, which includes requirements analysis, user interface design, system implementation, and testing. Test results show that the system functions effectively, features an intuitive interface, and can accurately and in real time record student attendance. Integration with GPS and the Android device's camera allows the system to validate presence based on both location and facial identity. This system is expected to support a more secure, efficient, and comprehensive digitalization of attendance management in higher education.
