The rapid expansion of information technology and the internet has driven the widespread adoption of e-commerce as a primary medium for online transactions. Nevertheless, numerous platforms continue to encounter challenges in their User Interface (UI), which negatively affect overall user experience. This study aims to evaluate and enhance the Sayurbox website interface by applying a User-Centered Design (UCD) approach to ensure stronger alignment with user needs and expectations. The research methodology includes observation, literature review, questionnaire distribution, development of user personas, requirement analysis, wireframe creation, high-fidelity design, and evaluation using the System Usability Scale (SUS), involving 45 respondents as representative users. The initial evaluation yielded an average SUS score of 33.07, categorized as Poor and Not Acceptable, indicating low effectiveness, efficiency, and user satisfaction with the existing interface. Following the UCD-based redesign, the SUS score improved to 61.06, classified as Marginal Acceptable, reflecting an 84% increase. This improvement was accompanied by a shift in user feedback from fundamental usability problems—such as navigation issues, readability constraints, and layout inconsistencies—to more detailed and refinement-oriented suggestions. These outcomes demonstrate a substantial enhancement in user experience, although further interface optimization remains possible. The study produces an interactive prototype along with initial front-end and back-end implementations that can serve as a basis for continued development. Overall, the findings contribute to improving UI/UX quality within e-commerce platforms and provide valuable references for academic research related to UCD application in evaluating and refining website interfaces.

Processing (NLP) using the Dialogflow platform as a solution to improve information services at the Library of SMK Negeri 1 Pugung. Currently, information services in the library are still carried out manually, requiring students and teachers to wait for staff assistance to obtain information regarding book collections, borrowing procedures, returns, operating hours, and applicable fines. This approach is less effective and does not align with the modern demand for fast, practical, and accessible services at any time. The chatbot developed in this research is designed to understand conversations in natural language through NLP features provided by Dialogflow, allowing it to deliver interactive and relevant responses based on user queries. The development process includes several stages, such as user needs analysis, design of intents and entities in Dialogflow, creation of conversation scenarios, and testing with real users within the library environment. The evaluation results indicate that the chatbot is capable of providing responses with adequate accuracy and can answer most commonly asked questions addressed to library staff. Beyond enhancing service effectiveness, the chatbot offers additional benefits, such as continuous availability without time restrictions and reduced operational workload for library personnel, especially for recurring questions. Therefore, this system represents a promising innovation for academic service improvement and a step toward integrating digital technology into school-based library services.
