<![CDATA[SMK Muhammadiyah 4 Sangkapura faces serious operational constraints due to its manual administration system. The offline and physical New Student Admission (PPDB) process slows down workflows and is prone to data errors. Furthermore, the absence of a centralized and integrated alumni tracking (tracer study) system causes graduate data to be scattered, unstructured, and complicates the fulfillment of school accreditation data. This research aims to design and build a functional and responsive WordPress-based school website. Specifically, this website is designed to integrate three main functions: (1) school information and promotion media, (2) a structured online PPDB system, and (3) a centralized alumni tracer study platform. The research method uses Research and Development (R&D) with the Waterfall development model, which includes stages of needs analysis, system design (UML), implementation (WordPress), and testing. Data collection used observation techniques, in-depth interviews with school staff, and document studies. Data analysis and system evaluation techniques used Black-Box Testing for functional feature validation and Usability Testing with the System Usability Scale (SUS) instrument to measure the feasibility and acceptance of end-users. The result is a school website that is proven to be functional, responsive, and meets user needs with an average usability score of 83. The implementation of the online PPDB system has successfully replaced the manual process, making the registration flow more efficient, transparent, and widely accessible. The tracer study feature has also successfully centralized the alumni database, which was previously fragmented, providing a more professional and structured tracking mechanism to support accreditation needs.]]>
