<![CDATA[The rapid development of digital technology has transformed office administration practices, requiring vocational education institutions to equip students with competencies in OfficeAsset Lab. However, learning activities in vocational schools are still frequently dominated by conventional methods that provide limited opportunities for students to develop practical digital skills. This study aimed to develop a OfficeAsset Lab learning media to improve students' competencies in managing office assets through an interactive digital learning environment. The study employed a research and development approach using the Analysis, Design, Development, Implementation, and Evaluation model. The product was validated by media and subject matter experts and subsequently tested through small-group and large-group trials involving vocational high school students. The collected data were analyzed using descriptive quantitative and qualitative techniques based on expert validation, student responses, and learning outcomes. The findings indicate that the developed learning media achieved a high level of validity in terms of content, design, functionality, and usability. The implementation results also demonstrate that the media effectively improves students' understanding of office asset management, enhances practical skills in digital documentation and inventory management, and increases learning motivation and engagement through interactive simulations. The developed learning media provides an authentic digital office experience that aligns with current workplace demands and supports competency-based vocational education. The novelty of this study lies in the integration of OfficeAsset Lab simulations into a comprehensive learning platform that combines interactive practice, digital documentation, and competency assessment to strengthen students' readiness for the digital workplace.]]>
