<![CDATA[State Polytechnic Manufacture of Bangka Belitung operates a mechanical workshop that serves as a practical training facility for mechanical engineering students. The high utilization rate of machines necessitates a well-structured preventive maintenance system to sustain optimal performance. However, the existing maintenance process is still conducted manually, leading to inefficiencies, schedule delays, and errors in maintenance records. This study aims to design and develop a web-based preventive maintenance system using the Laravel framework and the Agile (Scrum) development method. The system features include machine data recording, maintenance scheduling, automated notifications, digital reporting, and integration with Google Calendar to facilitate timely maintenance reminders. Black-box testing results confirmed that all system features functioned as intended and met user requirements. Based on a questionnaire survey of 50 respondents, 86% indicated that the system is highly important for improving maintenance efficiency, and 82% rated the notification feature are effective in optimizing maintenance schedule reliability. Implementation results demonstrated an improvement in maintenance regularity from 65% to 95%, a reduction in machine downtime by approximately 45% compared to the initial condition, and an increase in Overall Equipment Effectiveness (OEE) from 57.4% to 81.7%. These findings show that the developed system effectively enhances the operational efficiency of the mechanical workshop, extends machine lifespan, and supports a documented, measurable, and sustainable maintenance management process.]]>
