RANCANG BANGUN DAN IMPLEMENTASI SISTEM ABSENSI SANTRI MENGGUNAKAN ESP32 BERBASIS RFID DI PONPES DAARUL HUDA SUKOHARJO

Abstract

Pondok Pesantren Daarul Huda Sukoharjo still relies on a manual handwritten attendance system, which is prone to recording errors, data loss risks, slow recapitulation, and potential attendance manipulation. This study aims to design and implement an Internet of Things (IoT)-based automated attendance system utilizing Radio Frequency Identification (RFID) technoLogy and the ESP32 microcontroller to enhance the accuracy and efficiency of student attendance recording. The development methodoLogy employed is the Waterfall model, comprising requirement analysis, design, implementation, testing, and maintenance. The hardware architecture integrates the RFID RC522 sensor, ESP32, a Buzzer, and LED indicators, while the software infrastructure leverages the Python Flask Framework for the backend server and Web Monitoring Dashboard. The built Python Flask-based Web monitoring application successfully delivers core features, including a Real-Time attendance monitoring Dashboard, data visualization through daily and weekly charts, and attendance Log recapitulation tables, facilitating pondok administrators in digitally managing, filtering, and tracking student discipline. Black Box Testing results demonstrate that all system functions executed successfully with 100% functional accuracy in card recognition and attendance recording. Performance testing indicates a highly responsive system, achieving an average data transmission latency of 1.17 seconds and an optimal RFID reading range of 0–5 cm. Under extreme condition testing, the system achieved a 74% Success Rate, which rose to 90% under normal operating conditions, complemented by a Wi-Fi auto-reconnection feature with a 100% Success Rate. The implementation of this system has successfully digitized attendance administration for 17 students and simplified Real-Time discipline monitoring.
