A team of lecturers and students from the Engineering Department of Politeknik Negeri Jember (Polije) has developed an Internet of Things (IoT)-based Smart Bin designed to automate waste sorting and improve campus waste management. The innovation was introduced as part of Polije’s commitment to supporting environmental sustainability and advancing smart campus initiatives.

The Smart Bin is equipped with intelligent sensors capable of identifying different types of waste and automatically directing them into the appropriate compartments. By reducing the need for manual sorting, the system helps improve waste segregation efficiency while minimizing environmental pollution caused by improper disposal practices.

According to Muhammad Ar Rafi’, one of the student developers, the project was created to address growing waste management challenges through the application of modern technology. The system utilizes advanced sensors and an ESP32 microcontroller, which serves as the core component for integrating the device with IoT networks.

The Smart Bin can automatically separate multiple categories of waste and transmit operational data in real time. Through IoT connectivity, the device continuously monitors waste levels and sends information to a centralized monitoring platform, enabling more effective waste management.

One of the innovation’s key features is its real-time notification system. Cleaning staff can receive alerts when a bin reaches its maximum capacity, allowing them to respond promptly and prevent overflowing waste containers. This feature enhances operational efficiency and contributes to maintaining a cleaner campus environment.

The project supervisor, Wendy Triadji Nugroho, highlighted the Smart Bin’s ability to automatically open and close using sensor-based technology. He explained that future development plans include expanding the system’s capabilities through a dedicated mobile application that will allow users and facility managers to monitor waste conditions directly from their smartphones.

Beyond campus implementation, the development team envisions broader applications for the technology. The Smart Bin is expected to serve as a model for smart waste management systems that can be adopted by local governments, public facilities, and community organizations seeking sustainable solutions to waste-related challenges.

The creation of the IoT-based Smart Bin demonstrates Polije’s commitment to combining education, innovation, and environmental responsibility. By empowering students to develop practical technological solutions, the institution continues to contribute to sustainable development while preparing graduates to address real-world challenges through engineering and digital innovation.
