| Abstract | This research aims to evaluate the impact of sustainable user interface design on usability performance compared to conventional user interface design within the context of an e-commerce application. The study employs a comparative experimental approach with two versions of the prototype, randomly assigning 50 participants into two equal groups to test the prototypes via the Maze platform. The usability testing encompasses four real-world purchase scenarios password recovery, product search and cart addition, cart item management, and payment method addition. Usability was assessed using key metrics, including the System Usability Scale (SUS), Customer Effort Score (CES), time on task, misclick rate, and task success rate. Benchmark thresholds for each metric were established based on a synthesis of previous research and expert opinions from user experience professionals. The collected data were analyzed using independent samples t-tests with a significance level of 0.05. The results indicated that the prototype designed with sustainability principles achieved significantly higher System Usability Scale scores and lower Customer Effort Scores compared to the conventional design. Additionally, it reduced time on task and misclick rates by approximately ten to fifteen percent across all scenarios. These findings confirm that integrating sustainable design concepts can enhance user efficiency, effectiveness, and satisfaction, while simultaneously reducing system resource usage. |
