<![CDATA[Efficient and effective waste management is crucial for maintaining cleanliness and environmental health, especially in school environments. This research aims to develop and implement a Smart Trash Can system based on the Internet of Things (IoT) and microcontroller as an intelligent solution for waste management at Building B of the Maitreyawira Foundation in Batam. The system is designed to detect the fill level of trash bins in real-time and send notifications to the management center via the IoT network. The Smart Trash Can utilizes ultrasonic sensors to measure the volume of waste and an ESP32 microcontroller to process the data. Information regarding the fill status of the trash bins is transmitted through wireless communication modules to a central server integrated with a web-based application, allowing the building management to monitor and manage waste more efficiently. Test results based on blackbox testing tables show that this prototype functions well, with a detection accuracy rate of 95%. The system can provide accurate information about the fill level of the trash bins and reduce manual checking frequency by up to 80%, thus enhancing the operational efficiency of waste management at Building B of the Maitreyawira Foundation. With the implementation of this technology, it is expected to improve environmental cleanliness and make a positive contribution to better waste management in urban areas.]]>
