Rancang Bangun Aplikasi Presensi Siswa Berbasis Website Menggunakan Teknologi QR Code

Abstract

Attendance recording (presence) is a crucial activity in the educational environment to monitor student participation. However, the attendance system at SMK Perkasa 2 Cimanggung, which still relies on manual methods, has proven to have various significant weaknesses, including process inefficiency, high vulnerability to recording errors, and difficulties in effectively supervising students. This problem is exacerbated by the absence of a direct notification system to parents regarding student absences and the potential for forgery of permission letters, which can interfere with data accuracy. Therefore, this research aims to design and build a web-based student attendance application utilizing QR Code technology as a modern solution to overcome this series of problems. To achieve this goal, this research applies the waterfall model of system development. This approach was chosen because of its structured and systematic workflow, covering sequential stages starting from in-depth system requirements analysis, followed by architectural and user interface design, implementation through coding, to thorough system functionality testing to ensure the application can run in accordance with the expected objectives and provide a concrete solution for the school.
