Usability Analysis and UI Improvements of Museum Nasional Website Using Heuristic Evaluation Methodology

The National Museum of Indonesia (MNI) hosts collections in archaeology, history, ethnography, and geography. Its website serves as a key tool for publicizing museum-related information. This study aims to improve the website's usability by addressing menu navigation, information presentation, appearance, and wording through Heuristic Evaluation. This method assesses ten key aspects: system status visibility, real-world match, user control and freedom, consistency and standards, error prevention, recognition over recall, flexibility and efficiency, aesthetic and minimalist design, error recognition and recovery, and help and documentation. Initial evaluations using the System Usability Scale (SUS) yielded a poor usability score of 44 out of 100. Heuristic Evaluation highlighted issues in principles H1, H2, H3, H4, H6, H7, H8, and H10. Post-improvement, prototype evaluations showed successful UI/UX enhancements, reducing severity ratings to below 1 for all principles with testing provided valuable feedback in several key areas such as Enhanced Visual Appeal Users, Increased Accessibility of Key Information Feedback, and Positive Response to Call-to-Action (CTA) Redesign Users.
