Trash to Treasure (3T) Transforming Waste into Valuable Resources

Bubble tea has become a popular drink, favored by many people in Indonesia. Many outlets have started offering bubble tea, including Chatime. From February 2022 to June 2023, the plastic waste generated by Chatime reached 1737 kilograms. To address this issue, this research developed a machine to manage plastic waste at Chatime outlets. This research, titled Trash to Treasure (3T), uses the You Only Look Once (YOLO) algorithm and ESP-32 CAM to identify and process Chatime cups. Additionally, a website was developed using Flask to support the machine's functionality. The machine is designed to accept Chatime cups and provide points that can be exchanged for attractive items or vouchers, as shown on the website. Evaluation results show that the object detection model works well, with F1-score values 94,9%. The implementation in the form of software was successful, developing a user-friendly interface for both admin and users. This research benefits not only Chatime but also supports the community in the circular economy by providing an innovative solution to manage plastic waste. Thus, this research is expected to contribute significantly to plastic waste management and support environmental sustainability.
