Abstract

Sistem absensi mahasiswa memiliki peran penting dalam menunjang kedisiplinan dan evaluasi kehadiran di lingkungan akademik. Namun, praktik penyalahgunaan seperti titip absen
masih kerap terjadi, sehingga dibutuhkan sistem yang lebih valid dan otomatis. Penelitian ini mengusulkan rancangan dan implementasi sistem pelacakan posisi mahasiswa berbasis Bluetooth Low Energy (BLE) untuk mendukung validasi kehadiran melalui lokasi aktual mahasiswa di dalam kampus. Sistem ini menggunakan perangkat beacon portabel yang dibawa mahasiswa dan receiver statis yang dipasang pada titik-titik strategis seperti ruang kelas dan lorong, dengan pendekatan trilateration untuk estimasi lokasi berdasarkan sinyal BLE. Metodologi yang digunakan dalam penelitian ini adalah pendekatan prototyping, yang berfokus pada iterasi pengembangan dan pengujian sistem secara langsung. Dua jenis perangkat beacon digunakan, yaitu ESP32 dan JDY-33, yang masing-masing diuji dalam berbagai konfigurasi untuk mengevaluasi konsumsi daya dan ketahanan operasional. Sistem server dibangun menggunakan framework Flask untuk mengelola data secara real-time, serta dashboard yang menampilkan lokasi beacon aktif dan log deteksi dalam satu jam terakhir. Pengujian dilakukan pada skala kecil di lingkungan kampus Institut Teknologi Sepuluh Nopember tower 2 lantai 7 untuk mengukur efektivitas dan efisiensi sistem. Hasil pengujian menunjukkan bahwa sistem dapat mendeteksi beacon secara akurat di dalam ruangan dengan ambang batas rssi optimal sebesar -85 dBm. Dari sisi efisiensi energi, beacon JDY-33 menunjukkan konsumsi daya rata-rata sebesar 0.026–0.031 V per jam dan mampu menyala selama 39–43 jam tanpa mode sleep. Sementara itu, beacon ESP32 dengan konfigurasi deep sleep 8 menit mencatat konsumsi daya sebesar 0.032–0.034 V per jam, dengan durasi operasional sekitar 37–40 jam. Hasil ini membuktikan bahwa sistem tidak hanya berhasil dalam aspek akurasi pelacakan, tetapi juga efisien dari sisi konsumsi energi.

The student attendance system has an important role in supporting discipline and attendance evaluation in the academic environment. However, abusive practices such as leaving attendance still often occur, so a more valid and automated system is needed. This research proposes the design and implementation of a Bluetooth Low Energy (BLE)-based student position tracking system to support attendance validation through the actual location of students on campus. This system uses portable beacon devices carried by students and static receivers installed at strategic points such as classrooms and hallways, with a trilateration approach for location estimation based on BLE signals. The methodology used in this research is a prototyping approach, which focuses on iterations of hands-on system development and testing. Two types of beacon devices were used, namely ESP32 and JDY-33, each of which was tested in various configurations to evaluate power consumption and operational robustness. A server system was built using the Flask framework to manage real-time data, as well as a dashboard that displays the location of active beacons and detection logs in the last hour. Tests were conducted on a small scale in the campus environment of Institut Teknologi Sepuluh Nopember tower 2 7th floor to measure the effectiveness and efficiency of the system. The test results show that the system can accurately detect beacons indoors with an optimal rssi threshold of -85 dBm. In terms of energy efficiency, JDY-33 beacons show an average power consumption of 0.026-0.031 V per hour and are able to light up for 39-43 hours without sleep mode. Meanwhile, ESP32 beacons with an 8-minute deep sleep configuration recorded a power consumption of 0.032-0.034 V per hour, with an operational duration of about 37-40 hours. These results prove that the system is not only successful in terms of tracking accuracy, but also efficient in terms of energy consumption.
