ECO NOTES: UX DESIGN OF A VILLAGE WASTE RECORDING APPLICATION WITH REWARD SYSTEM INTEGRATION USING THE USER-CENTERED DESIGN METHOD

Abstract

Village waste management currently has two main problems: lack of a digitally integrated waste recording system and low community participation in sorting waste due to lack of incentives. This study aims to design a prototype of the ECO Notes application as a village-based waste recording solution, adapting features and interfaces through a User-Centered Design (UCD) approach. Comparison with current methods shows that the Digital Waste Bank focuses more on transaction recording, while the IoT-based Waste Monitoring System,  effective for city scale, is less suitable for village limitations. The design methodology includes conducting literature studies and interviews with village officials and local communities to identify functional and non-functional needs, followed by the creation of low-fidelity and high-fidelity prototypes. Evaluation was conducted using a User Experience Questionnaire (UEQ) comprising six rating scales on 12 respondents. The evaluation results showed that the highest scores in the Perspicuity aspect (1.68), indicating ease of understanding of the application, and Novelty (1.25), reflecting the solution's novelty compared to previous methods. Overall, the application received positive responses in all aspects, confirming its advantages in accessibility, sustainability, and community engagement. Thus, ECO Notes is considered worthy for further development and testing on a wider-scale user
