<![CDATA[The rapid development of digital technology in education has encouraged the implementation of e-learning systems as flexible and interactive learning media. However, several usability problems still exist, such as confusing navigation, unresponsive user interfaces, and limited interactive features that reduce the overall user experience. In addition, previous studies on UI/UX optimization in e-learning systems have mainly focused on visual aspects and feature development without deeply applying a user-centered approach, particularly in non-formal coding education platforms. This study aims to optimize the usability of the e-learning system interface at Les Coding Edutech Community using the Design Thinking method. The research method consists of five main stages: Empathize, Define, Ideate, Prototype, and Testing. Data collection was conducted through observations, interviews, and questionnaires distributed to 25 active students using the e-learning system. The developed interface prototype was evaluated using the System Usability Scale (SUS) method to measure system usability. The results indicate that the implementation of the Design Thinking method successfully improved the interface quality, making the system simpler, more interactive, and easier to use. The SUS evaluation produced an average score of 78, categorized as Acceptable with a Good grade. These findings demonstrate that the e-learning system has a good usability level and is capable of supporting a more effective and comfortable digital learning experience for users.]]>
