SOCIALIZATION OF THE IMPLEMENTATION OF SMART WASTE BASED ON THE INTERNET OF THINGS (IoT) AS AN INNOVATION IN MONITORING AND WASTE MANAGEMENT AT UKM SRR, MALIKUSSALEH UNIVERSITY

Abstract

Waste management is an important aspect in creating a clean, healthy, and sustainable campus environment. Problems often found in waste management are the lack of monitoring of trash bin capacity and the mixing of wet and dry waste. The development of Internet of Things (IoT) technology provides an opportunity to overcome these problems through a digital trash bin monitoring system. This community service activity aims to introduce IoT-based Smart Waste Bin technology to members of the SRR Student Activity Unit (UKM) of Malikussaleh University as an innovation in waste management. The activity was carried out on October 12, 2026 through a socialization approach, material delivery, component introduction, technology demonstration, and interactive discussion. The technology introduced uses a Wemos D1 Mini (ESP8266) microcontroller, an HC-SR04 ultrasonic sensor to measure the fullness of the trash bin, and a Capacitive Soil Moisture Sensor v2.0 to detect the presence of wet waste. Information from sensor readings is displayed through a web-based dashboard that can be accessed via the internet. Based on the tool development research that underpins the activity, the HC-SR04 sensor achieved a measurement accuracy of 95.39%, while the humidity sensor achieved a classification accuracy of 92.00%. This outreach activity aimed to increase participants' knowledge regarding the use of IoT and encourage the application of technological innovation in waste management on campus. Evaluation of participants' knowledge gains still requires data from the implementation of the activity.
