Abstract

Rapid advancement of Information Technology has accelerated the flow of information and data. The National Institute of Technology (Itenas) has improved its services with an online graduation registration system (Pendaftaran Wisuda Online). However, based on observations and the result of Post-Study System Usability Questionnaire (PSSUQ) revealed negative experiences on the website. Based on PSSUQ scores, where lower values indicate better performance, it averaged 3.31 for SYSUSE, 3.41 for INFOQUAL, and 3.71 for INTERQUAL, all of which exceeded the Upper Limit of PSSUQ. This suggests room for enhancing usability and user experience. Addressing this, a study focused on redesigning Itenas’ Graduation Registration website using the Lean UX approach and evaluating it through Usability Testing and PSSUQ. The results of usability testing included effectiveness, efficiency, and satisfaction aspects. Effectiveness scored 90.5%, surpassing the 78% average. Efficiency achieved a time of 0.0658 goal/seconds. For the satisfaction aspect, assessed by PSSUQ, achieved significant results, where all sub-scales received scores below the Lower Limit, indicating excellent performance, showed excellent performance with scores below the Lower Limit. SYSUSE scored 1.55, INFOQUAL 1.92, INTERQUAL 1.38, and OVERALL, 1.65. These results indicate that UI/UX improvements fulfilled user needs, marking a successful overhaul of the Itenas Graduation Registration website.
