<![CDATA[Household organic waste management remains a major challenge in urban areas due to the lack of integrated collection services and low public motivation. This study aims to design the user interface of the “EcoHarvest” application, which serves as an organic waste drop-off platform connecting users with waste management partners. Employing the Design Thinking methodology, the study translates user requirements into a functional interface featuring waste-weight tracking, drop-off location mapping, and a reward-based points system integrated with UTAUT and gamification principles. Usability testing conducted using the System Usability Scale (SUS) with 50 respondents yielded an average score of 69.2 (Grade B). This result indicates an acceptable level of usability for the application prototype. These findings represent a preliminary evaluation of a UI/UX prototype, highlighting its potential to streamline household waste management prior to full system implementation.]]>
