Development Of Smart Energy Monitoring Internet of Things System Based on App Inventor for Electric Energy Efficiency

Electricity Demand for electrical energy in the food industry, including restaurants, continues to increase alongside the use of high-powered production equipment. This study aims to develop an Internet of Things (IoT)-based electrical load monitoring and control system using App Inventor at the Bakmi GM Denpasar production unit. The system consists of two components: a server (App Inventor) and a client (a microcontroller device based on a current sensor). Methods used include hardware design for power consumption data acquisition and development of a user interface for real-time monitoring and control. Test results show that the system can detect and manage electrical loads with 96.8% accuracy and reduce energy consumption by 18.5%, compared to before the system was implemented. These results demonstrate that integrating IoT technology into industrial electricity systems can significantly improve energy efficiency, reduce energy waste, and support environmental sustainability.
