Perancangan sistem absensi online berbasis qr-code studi kasus: dosen dan mahasiswa program studi sistem informasi universitas pgri silampari menggunakan metode prototipe
This research aims to design and develop a QR Code-based attendance information system for lecturers and students in the Information Systems Study Program at Universitas PGRI Silampari using PHP and MySQL. The system was developed to overcome problems associated with the existing manual attendance process, including recording errors, delays in data processing, and the potential for attendance data manipulation. The system was developed using the Prototype development method, which consists of requirements analysis, prototype design, evaluation, refinement, implementation, and system testing. System testing was conducted using the Black Box Testing method to ensure that all system functions operated according to user requirements. The test results indicated that all system features, including user login, lecturer and student data management, QR Code generation, attendance recording, and attendance report generation, functioned successfully with a 100% success rate. Therefore, the developed system is considered valid and capable of improving the efficiency and accuracy of attendance management, simplifying attendance monitoring, and supporting faster, more accurate, and well-structured report generation.
