Abstract

This study aims to evaluate improvements in the usability quality of the Sumber Alam Express application prototype using the Heuristic Evaluation method. The test results show that out of the ten heuristic evaluation factors, nine received high/agree ratings, while one factor received a moderate/neutral rating. There was a significant improvement across all factors compared to the previous study. Notably, "help users recognize, diagnose, and recover from errors" increased by 43.7%, and "help and documentation" improved by 42.5%. The only factor that remained at a neutral level was "flexibility and efficiency of use," which was due to the absence of shortcut features in the prototype—despite the application's flow remaining clear and easy to understand. The validity test indicated that one questionnaire item was invalid, mainly due to the limited number of respondents. This study involved 10 purposively selected respondents with diverse backgrounds, including employees and students who are active users, users of similar applications, and a frontend developer. Although the number of respondents was smaller than in the previous study, the diversity and depth of their experience ensured a comparable level of data representativeness. This research acknowledges its limitations, particularly the small sample size and partial instrument validity, both of which were constrained by time and resource limitations during the data collection process.

Abstract

The Sumber Alam Ekspres mobile application is designed to facilitate users in booking bus tickets. Since its launch in December 2020, the app has garnered over 35,000 downloads, averaging 48 downloads per day. Currently, it holds a rating of 4.1 out of 5 on the Google Play Store. User reviews—207 in total—reveal various complaints, particularly regarding mismatched information, malfunctioning features, and unintuitive interface design. To investigate these issues, a usability evaluation was conducted using the Heuristic Evaluation Method with 20 respondents representing different user types and statuses. The evaluation revealed that only one usability principle—Visibility of System Status—achieved a high score (69%). Six heuristics received moderate ratings: Match Between System and the Real World (62.5%), User Control and Freedom (56.5%), Consistency and Standards (53.5%), Error Prevention (52.5%), Recognition Rather Than Recall (59.5%), and Aesthetic and Minimalist Design (63.5%). Meanwhile, three heuristics were rated low: Flexibility and Efficiency of Use (42%), Help Users Recognize, Diagnose, and Recover from Errors (37%), and Help and Documentation (38%). These findings highlight specific areas for improvement in the user interface, particularly in providing adequate guidance, improving efficiency, and ensuring a more intuitive user experience.
