DEVELOPMENT OF AN IoT-BASED SMART ELECTRICAL CONTROL SYSTEM FOR ENERGY EFFICIENCY IN BUILDINGS

Ilham Maulana Kanuri, Muhammad Rayhan Febriansyah

Abstract


Efficiently managing electrical energy consumption is a major challenge in the industrial sector, particularly in production facilities that use high-power equipment. Conventional electrical control systems often lead to energy waste due to devices remaining active outside of operating hours and a lack of real-time monitoring. This research proposes and implements an Internet of Things (IoT)-based smart electrical control system to improve energy efficiency at PT Ajinomoto Indonesia's facilities.
The developed system utilizes hardware such as an ESP32 microcontroller, ACS712 current sensor, PIR sensor, and relay module, along with software based on Laravel, Node-RED, and the MQTT protocol. Key features include real-time energy consumption monitoring, automatic device control based on occupancy detection and operational schedules, anomaly notification, and the generation of analytical reports accessible online. Test results show the system can respond to device status changes in less than 3 seconds and achieve a 99.8% data delivery success rate. Based on a two-week simulation, projected energy savings reach 20% compared to conventional methods.
This research proves that the application of IoT in energy management can increase efficiency, support data-based decision-making, and contribute to the implementation of green building concepts and energy sustainability in the industrial sector.
