Inovasi IoT untuk Efisiensi Energi Listrik di Madrasah Tsanawiyah

Abstract

Electrical energy waste in madrasah environments often occurs due to the absence of a centralized monitoring system, causing electronic devices such as lamps and fans to remain active outside operational hours. This study aims to analyze the effectiveness of Internet of Things innovation in improving electrical energy efficiency at MTs DDI Al-Amin, Makassar. The method employed is a quantitative case study by comparing waste duration patterns before and after the implementation of IoT devices integrated with the Blynk platform and Telegram Bot. Prior to analysis, the instrument was validated by comparing system readings against reference measuring instruments, yielding error rates of 0.37% for voltage, 0% for current, and 0.43% for power. The simulation estimation results show that the duration of devices running idle decreased from 2.08 hours per day to 0.75 hours per day, yielding a net energy saving of 0.3325 kWh per day, equivalent to 8.645 kWh per month, with a monthly electricity cost reduction of approximately Rp11,239.00. The simulation of notification effectiveness through Telegram also indicates a potential increase in collective awareness. The primary constraint, wireless network fluctuations, can be mitigated through an auto-reconnection mechanism. This study concludes that IoT innovation serves not only as a remote control tool but also as an effective behavioral trigger for energy-saving habits in the madrasah environment.
