Abstract

Search and Rescue (SAR) operations for river-drifting victims represent emergency situations frequently encountered in the field and pose a high risk to the safety of SAR personnel. Therefore, a supporting device capable of providing fast and accurate location information is required to improve the effectiveness of search operations. This study aims to design and develop a prototype of an Emergency Locator Card based on GPS and Bluetooth Low Energy as a safety support device for SAR personnel. The proposed system employs a Soil Moisture Sensor as an automatic activation trigger when wet conditions are detected. Once activated, the Neo-6M GPS module is used to obtain geographical coordinates, while the SIM800L GSM module transmits location information to user devices via the cellular network. In addition, Bluetooth Low Energy is utilized to support short-range tracking through beacon signals. Visual and audio indicators in the form of LEDs and a Buzzer are implemented to facilitate on-site identification. All data processing and system control are handled by the ESP32 microcontroller. System performance evaluation was conducted using the developed prototype. The test results indicate that the system exhibits a good response time, with an average of ±1 second required for sensor detection from dry to wet conditions. GPS accuracy testing shows an average positioning error of 6.3% relative to the actual location. The total system response time from activation until all indicators operate is 11.51 seconds. Furthermore, the effective range testing demonstrates that BLE, LED, and Buzzer functions remain effective for short-range tracking. In terms of power consumption, the system is capable of operating for approximately 2 hours under full operating conditions. These results indicate that the proposed prototype has the potential to be further developed as a supporting device for SAR operations in river environments. Keywords: SAR, Emergency Locator Card, ESP32, GPS Neo-6M, Bluetooth Low Energy Operasi pencarian dan pertolongan (Search and Rescue/SAR) terhadap korban hanyut di sungai merupakan kondisi darurat yang sering dihadapi oleh tim SAR dilapangan dan memiliki tingkat resiko tinggi terhadap keselamatan personel. Oleh karena itu, diperlukan perangkat pendukung yang mampu memberikan informasi lokasi secara cepat dan akurat guna mempercepat proses pencarian. Penelitian ini bertujuan untuk merancang dan membangun prototipe Emergency Locator Card berbasis GPS dan Bluetooth Low Energy sebagai perangkat pendukung keselamatan personel SAR. Sistem yang dirancang menggunakan Soil Moisture Sensor sebagai pemicu aktivasi otomatis ketika alat mendeteksi kondisi basah. Setelah teraktivasi, modul GPS Neo-6M berfungsi untuk memperoleh koordinat lokasi, dan modul GSM SIM800L digunakan untuk mengirimkan informasi lokasi melalui jaringan seluler ke perangkat pengguna. Selain itu, Bluetooth Low Energy dimanfaatkan untuk mendukung pelacakan jarak dekat melalui sinyal beacon. Sebagai indikator tambahan, LED dan Buzzer digunakan sebagai penanda visual dan audio guna memudahkan proses identifikasi di lapangan. Seluruh proses pengolahan data dan pengendalian sistem dilakukan oleh mikrokontroler ESP32. Pengujian dilakukan menggunakan prototipe yang telah dibangun untuk mengevaluasi kinerja sistem secara menyeluruh. Hasil pengujian menunjukkan bahwa sistem memiliki waktu respons yang baik, dengan waktu rata-rata ±1 detik pada proses deteksi sensor dari kondisi kering ke basah. Pengujian akurasi GPS menghasilkan error jarak sebesar 6,3% terhadap titik lokasi sebenarnya. Waktu total respons sistem sejak aktivasi hingga seluruh indicator bekerja mencapai 11,51 detik. Pengujian jarak efektif menunjukkan bahwa Bluetooth Low Energy, LED dan Buzzer masih dapat digunakan secara optimal sebagai pendukung pelacakan jarak dekat. Dari sisi konsumsi daya, sistem mampu beroperasi selama ±2 jam pada kondisi operasi penuh. Hasil ini menunjukkan bahwa prototipe yang dirancang memiliki potensi untuk dikembangkan lebih lanjut sebagai perangkat pendukung operasi SAR di lingkungan sungai.
