UI/UX Optimization of an Android-Based Waste Management Application Using Design Thinking and the System Usability Scale

Abstract

Community-based waste management increasingly relies on mobile applications, whose success depends heavily on the quality of the User Interface (UI) and User Experience (UX). This study designed and evaluated the UI/UX of a high-fidelity prototype of the Resikel Android application for the Batam City context using the Design Thinking methodology (Empathize, Define, Ideate, Prototype, Test). The contribution is context-specific rather than methodological: it presents a user-centered interface design and its perceived-usability evaluation for a community-based waste-management prototype situated in Batam. Usability was measured through unmoderated, cross-sectional testing on the Maze platform involving 100 respondents, followed by the System Usability Scale (SUS). Task-based metrics (success rate, completion time, and misclicks) were recorded, and the mean SUS score was 78.2 (SD = 6.70), indicating a good level of perceived usability within the Acceptable range. Because the artifact evaluated is a prototype rather than a functioning Android application, technical feasibility, performance, accessibility, and real-world task completion were not established. The findings provide an empirical usability reference for the future development of community-based waste-management applications and should be interpreted within the stated design and sampling limitations.
