Rancang Bangun Sistem Keamanan Anti Maling Pembangkit Listrik Tenaga Surya Portable Berbasis Telegram Menggunakan NODE MCU ESP32

Abstract

This research focuses on the design and implementation of an innovative anti-theft security system for portable Solar Power Plants (PLTS), integrated with the Telegram notification platform and controlled by Node MCU ESP32. The increasing utilization of portable PLTS as an alternative energy solution has elevated its value, simultaneously making it a vulnerable target for theft. Therefore, the need for a security system capable of providing real-time responses and alerts becomes crucial. The primary objective of this research is to develop an effective security system for detecting and preventing the theft of portable PLTS. The constructed system is designed to automatically activate visual (LED) and audible (buzzer) alarms, and send instant warning notifications to the user's Telegram account upon detection of suspicious activity. Node MCU ESP32 functions as the main control unit and IoT module, enabling internet connectivity for real-time communication. Threat detection is carried out through a combination of a PIR (Passive Infrared) sensor to detect movement around the PLTS and a magnetic field sensor specifically designed to detect displacement or attempts to move the solar panel from its position. The process involved the design of the hardware prototype, firmware development using Arduino IDE, and comprehensive testing. Performance test results indicate high system capability: the Node MCU ESP32 successfully maintained a stable network response speed with an average time of 1.157 seconds, while Telegram notification delivery showed a very low average delay of 2.027 seconds. The maximum detection range for the PIR sensor was 7 meters, with an effective detection range of 6 meters. The detection range for portable solar panel displacement was 6 mm, with an effective range of 8 mm. This data empirically proves that the developed security system is capable of providing reliable and responsive protection against potential theft of portable PLTS
