Cleanliness problems and lack of awareness in sorting waste are still important issues in the campus environment. This research aims to design and build an Arduino Uno-based automatic trash can system that is able to automatically sort waste based on its type, namely metal, organic, and non-organic. The system is designed using a combination of inductive proximity sensors to detect metals, capacitive sensors to detect non-metallic materials, and ultrasonic sensors to detect the presence of objects. Additional components such as servo motors are used to drive the keg caps, and LCDs are used as information display media. The design method is carried out through the stages of needs analysis, hardware assembly, microcontroller programming, and functional testing. The test results showed that the system was able to recognize and direct waste to the right category with a 100% success rate in 30 tests, each for three types of waste. The system also displays information in real-time, providing educational value to users. With this success, the automatic trash can system is considered effective to be applied in the campus environment as an appropriate technological means that can encourage clean living behaviors, increase environmental awareness, and support more structured waste management.
