The Effect of Adding the Heuristic Evaluation Method to the Usability Evaluation Method of Design Thinking in the UNSIL Vclass Application

Siliwangi University’s VClass Application (UNSIL), launched in 2021, grappled with substantial interface issues affecting the user experience. The developer encountered challenges that significantly impacted user interaction and satisfaction. This study aims to identify usability problems in the UNSIL VClass application using the heuristic evaluation method, inserted at the empathize stage of the design thinking method, to identify specific and in-depth problems based on heuristic principles that users sometimes overlook. Data was collected from 70 students who actively used this application through the System Usability Scale (SUS) questionnaire. The initial evaluation results obtained a value of 54 with a score of F with an acceptance range of “not acceptable. However, with the application of the heuristic evaluation method, a prototype was successfully developed, which showed a significant increase in three main aspects of usability: effectiveness, efficiency, and satisfaction. Time completion was reduced by 86%, the error rate decreased by more than 90%, and the completion rate reached 100%. Testing the satisfaction aspect on the prototype using SUS showed a value of 61 with a score of D, with “acceptable” acceptance. The insertion has helped enrich the usability evaluation process and identified problems that users might have missed. This revision also provides alternative solutions to increase the usability of the UNSIL VClass application.
