Abstract

The attendance system at SMK Negeri 1 Talamau has so far been focused mainly on teachers and relies on a fingerprint method that frequently experiences problems such as reading failures, system errors, and delayed data synchronization. This research aims to develop a QR Code-based online attendance mobile application that can be used by both teachers and students in real time. The research method used is Research and Development (R&D) with the Waterfall software development model, covering the stages of requirements analysis, design, implementation, testing, deployment, and maintenance. The application was developed using WebApp as the mobile platform, Laravel as the backend, and MySQL as the database. The student attendance process is carried out by scanning a QR Code displayed by the teacher, after which attendance data is automatically stored in the database via a REST API. System testing was conducted through alpha testing (white box and black box) as well as beta testing involving experts and end users. The test results show that all primary system functions run according to the design. Beta testing with experts obtained an average score of 86%, categorized as very good, while beta testing with users obtained an average score of 96%, also categorized as very good. The developed application is considered feasible for use and able to improve the effectiveness and efficiency of the attendance process at the school.
