Abstract

Banjarwaru Village in Cilacap Regency is facing problems related to the lack of Public Street Lighting (PJU), with several vital road sections being dark at nite. This condition significantly reduces safety levels, increases the risk of crime and accidents, and hinders the mobility and socio-economic activities of the community. Residents, especially women and children, feel unsafe to go outside, which impacts religious, social, and economic activities. Responding to this urgency, this community service program aims to improve the quality of life and well-being of the Banjarwaru Village community through the application of appropriate technology. The proposed solution is the installation of two units of an Arduino-based smart street lighting system powered by solar energy. The implementation method for this service involves field observation and experimentation in the design and construction process of public streetlights, and technology transfer to the community. The results of creating a smart public street light based on Arduino with solar power supply function well. At night, electricity is supplied by batteries. The batteries are charged during the day, when the solar cells receive sunlight. The final activity in this series of community service, and the closing event, was the handover and guidance to the Banjarwaru community, thru the Village Head of Banjarwaru, on how the smart public street lighting system powered by solar energy works and how to maintain it.

Abstract

Mountain climbing activities involve a high risk of hikers becoming lost due to limited location information and the lack of reliable cellular network coverage in mountainous areas. This study aims to develop an Internet of Things (IoT)-based GPS tracking system utilizing Long Range (LoRa) communication to support real-time hiker location monitoring and emergency notification in cellular network blind-spot areas. The proposed system consists of an ESP32-based transmitter equipped with a GPS module, an SX1262 LoRa module, and an emergency push button, a LoRa gateway as the receiver, and a web-based monitoring platform for real-time location visualization. System performance was evaluated through GPS accuracy testing, emergency response time measurement, and LoRa communication performance in both urban environments and the Mount Slamet hiking trail. The experimental results indicate that the GPS positioning error ranges from 7.25 to 9.16 m, with an average error of 8.25 m. The emergency notification system achieved a 100% transmission success rate with a response time of 20–22 s. Communication testing demonstrated that LoRa provided reliable data transmission over distances of up to approximately 300 m in urban environments, while communication quality degraded at longer distances due to reduced Received Signal Strength Indicator (RSSI), increased packet loss, and the effects of terrain, vegetation, and Line-of-Sight (LoS) conditions along the hiking trail. These results demonstrate that the proposed system is capable of providing reliable location monitoring and emergency communication in areas with limited cellular coverage, making it a promising solution for supporting Search and Rescue (SAR) operations in mountainous environments.
