Usability Evaluation of the Portal Bali Malajah Virtual Class Application Using Performance Measurement, System Usability Scale, and Heuristic evaluation Methods

Abstract

The Portal Bali Malajah Virtual Classroom application is an innovative educational service that functions as a Learning Management System (LMS) to facilitate the teaching and learning process in Bali Province. However, since the application was first used, users have encountered obstacles, and a usability evaluation has not been conducted. This study evaluated the application using performance measurement to measure effectiveness and efficiency, a System Usability Scale (SUS) to measure user satisfaction, and a heuristic evaluation to identify interface issues. Data collection using performance measurement and heuristic methods was conducted through direct observation of respondents. Heuristic testing involved three experts to assess the application interface. The SUS questionnaire was distributed online to the entire study population. The performance measurement test showed a very effective category with an effectiveness of 98%, and an efficiency of 98.99%. The SUS score resulted in a user satisfaction level of 80.9. The heuristic evaluation identified interface issues with cosmetic and minor usability problems. The Bali Melajah Portal Virtual Class has met the aspects of effectiveness, efficiency, and user satisfaction well, but needs some improvements to the user interface. Improvement recommendations are compiled based on heuristic aspects to produce more targeted recommendations.
