Abstract

Landslide disasters occur when materials such as rocks, debris, soil, or mixtures thereof move down a slope or out of the slope. As a natural disaster, landslides can cause material loss and loss of life. To reduce the impact, a system is needed that can monitor soil conditions continuously real-time and provide early warning to people living in landslide-prone areas. This designed system integrates a landslide-based detection tool Internet of Things (IoT) with Android applications. The system uses Realtime Database to store data from sensors, software Android Studio for developing Android applications, as well as communications Long Range (LoRa) to send sensor data to the microcontroller. This system can display data on soil moisture, rain intensity, vibration and conditions directly. If danger is detected, a buzzer will sound, and the application will send notifications quickly and precisely. Tests show that the sensor can transmit data using LoRa with an Received Signal Strength Indicator (RSSI) value of -71 dBm at 10 meters under conditions of Line of Sight, and up to 100 meters with an RSSI value of -106 dBm in the presence of obstructions. With this system, it is hoped that people in landslide-prone areas will be more alert, so that the risk of loss of life and material loss can be reduced.

Abstract

Penelitian ini bertujuan merancang dan mengembangkan gelang GPS Tracker dengan komunikasi LoRa untuk memantau posisi pendaki gunung secara real-time di area tanpa sinyal seluler, serta memberikan notifikasi darurat. Sistem ini menggunakan modul GPS untuk menentukan lokasi pendaki dan modul LoRa untuk mengirimkan data lokasi ke sesama pendaki dan pos pendaki. Semua data pendaki, termasuk lokasi mereka, akan ditampilkan di aplikasi android. Pengujian dilakukan di Hutan UI dan Bukit Pelangi untuk mengevaluasi akurasi koordinat yang dikirimkan. Di Hutan UI, koordinat yang dikirimkan oleh Leader dan dua Pendaki menunjukkan kesesuaian dengan posisi sebenarnya, dengan akurasi hingga 0,000013° untuk lintang dan 0,00005° untuk bujur. Di Bukit Pelangi, deviasi koordinat maksimal sekitar 0,000043° untuk lintang dan 0,00006° untuk bujur. Sistem ini mampu melacak posisi pendaki secara akurat, menampilkan semua data pendaki, menyajikan laporan historis pergerakan dalam peta, serta memberikan notifikasi darurat yang cepat ke pemimpin pendakian dan pos pendaki. Gelang ini diharapkan meningkatkan keamanan pendaki dan mempercepat proses penyelamatan oleh tim SAR

Abstract

Electricity costs in boarding rooms are often unfairly distributed because each room is charged the same amount, even though electricity usage varies. To solve this problem, a system was created to monitor each room's power usage more efficiently using Long Range (LoRa) technology. This system uses an ESP32 microcontroller, a PZEM-004T sensor, and LoRa, programmed with Arduino IDE. The sensor collects power usage data and sends it to the boarding house owner over the LoRa network, with accuracy close to 99% in three tests. The data is transmitted up to 150 meters with an RSSI of -107 dBm in non-line-of-sight (NONLOS) conditions and up to 600 meters with an RSSI of -111 dBm in line-of-sight (LOS) conditions. It is also connected to an Android app for easier power management and monitoring.
