Perancangan Teknologi Radio Frequency Identification Dalam Sistem Presensi Peserta Didik Berbasis Internet of Things di Sekolah Menegah Pertama Sejahtera 2 Cileungsi

The manual student attendance system at SMP Sejahtera 2 Cileungsi presents several inefficiencies, such as susceptibility to recording errors, time-consuming procedures, and difficulties in accurately summarizing attendance data. Previous studies have proposed RFID and IoT-based systems to improve efficiency, yet most lack features for real-time parental notification. This study aims to develop an automated student attendance system using Radio Frequency Identification (RFID) integrated with the Internet of Things (IoT) and a Telegram bot for immediate communication with parents. The system was developed using the prototyping method, allowing for iterative refinement based on user needs. Attendance is recorded through RFID cards tapped on a reader device, with data stored in a database and exportable to PDF and Excel formats. Black box testing was conducted to validate system functionality. The results indicate that the system enhances accuracy, efficiency, and parental involvement by providing real-time updates. This research contributes to smart education technology by offering a scalable and interactive attendance model that supports administrative digital transformation in schools.
