Abstract

SIMANTEP UNIMED is a web-based Learning Management System used to support academic and administrative activities within the Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan. This study aimed to improve the user interface and user experience of the system by identifying user needs and implementing a gallery feature through a User-Centered Design (UCD) approach. The research employed interviews, observations, usability testing, Think-Aloud sessions, and Analysis of Verbal Behavior to evaluate the existing system and the proposed design prototype. A prototype was developed in Figma and assessed using usability attributes, including effectiveness, efficiency, and satisfaction. The results demonstrated substantive improvements in usability. The redesigned prototype achieved effectiveness and efficiency scores of 100%, while the satisfaction score reached 89.5 on the System Usability Scale. Verbal behavior analysis recorded 24 user comments, consisting of 58.3% positive, 29.2% neutral, and 12.5% negative comments. Compared with the initial evaluation, positive comments increased by 40.1%, while neutral and negative comments decreased by 13.2% and 26.9%, respectively. These findings indicate that the User-Centered Design approach successfully addressed usability issues and enhanced the overall user experience of SIMANTEP UNIMED. The proposed design can serve as a reference for future system development.
