Abstract
This study demonstrates the effectiveness of the Design Thinking approach in developing the UI and UX of the Justeatss.id e-commerce website. The process followed five stages including empathizing, defining, ideate, prototype, and test which are focusing on user needs as the foundation for design. Qualitative data from interviews and usability testing identified key issues such as difficult navigation, unappealing visual design, and checkout obstacles. High-fidelity prototypes were developed to create an intuitive, engaging, and responsive interface. Evaluation using the System Usability Scale (SUS), User Acceptance Testing (UAT), and the Customer Satisfaction Index (CSI) showed significant improvements in usability, functionality, and overall user satisfaction, with the website receiving an "Excellent" SUS score, a perfect UAT score, and 100% CSI rating. These results highlight that a user-centered Design Thinking approach can effectively optimize aesthetics, functionality, and emotional satisfaction, providing practical insights for enhancing e-commerce platform performance.
