Original abstract

In this modern era, renewable energy sources are crucial for reducing dependence on limited fossil fuels and the ever-increasing cost of electricity generation. One of the most effective ways to reduce electricity consumption and high operational costs in public street lighting systems is to use solar power as the primary power source. Solar Power Plants (PLTS) have become an environmentally friendly and efficient solution to meet energy needs in various sectors. Public street lighting plays a crucial role in improving the safety and comfort of road users at night. However, maintenance of street lighting systems often faces problems such as damage to some streetlamps that is not quickly detected. This can lead to prolonged inoperability of streetlamps and create discomfort for road users and even increase the risk of accidents. Therefore, this study aims to design and develop a solar-powered public street lighting system utilizing LoRa technology, based on the Internet of Things. This study uses an experimental method. This monitoring system comprises an LDR sensor to detect light intensity, a LoRa module for long-distance communication, and a microcontroller to process and transmit data to a central server. Data from the sensor is used to determine whether the streetlight is on or off and then sent to the control centre for analysis. Based on the study’s results, LoRa technology can be utilized for wireless communication between street lighting points, resulting in low power consumption. The condition of street lighting can be monitored remotely in real-time on a website via the internet.
