Indonesia's natural landscape, especially its mountains, attracts increasing climbers. However, the growing interest has led to more accidents in these areas. Given the lengthy evacuation processes for mountain accidents, an effective climber tracking system using IoT technology is essential. This study employs literature reviews and data collection on IoT-based monitoring systems utilizing Meshtastic LoRa devices and protocols. LoRa is chosen for its ability to overcome limited cellular signals in mountainous regions by using radio signals and mesh networks. The developed GPS tracker functions well, automatically sending data in coordinates and text every 5 minutes. In the LoRa mesh communication method, data is forwarded between interconnected nodes to avoid duplication, ensuring efficient communication. Stability tests showed the system operates reliably up to 1km in LOS conditions and up to 500 meters in NLOS conditions. More devices are needed to extend the mesh network, minimizing packet loss and delays. This research contributes to creating an effective GPS tracking system and alternative communication tool for mountain climbers, enhancing safety by reducing accident risks and improving location monitoring. ©2024 The authors.
