The gap between practical learning facilities in schools and the technologies applied in industrial settings remains a major challenge in vocational education, particularly in the mastery of control system competencies. This condition necessitates the development of innovative learning media capable of authentically and interactively representing industrial environments. This study aims to analyze and examine the effectiveness of a Virtual Reality-based Human Machine Interface learning medium in enhancing students’ control system competencies in vocational education. This research employed a development research design adopting the ADDIE model with both quantitative and qualitative approaches. The research subjects included students as end users as well as media and content experts who evaluated the feasibility of the developed product. Data were collected through learning outcome tests, observations, and questionnaires, using evaluation tests, observation sheets, and assessment questionnaires as instruments. Data analysis was conducted through expert validity testing, functional testing using black box testing, and paired-sample t-tests to examine improvements in learning outcomes. The results indicate that the developed learning medium demonstrates a very high level of feasibility and significantly improves students’ learning outcomes. Furthermore, the medium provides an immersive, interactive, and contextual learning experience. These findings suggest that the integration of Virtual Reality technology in control system learning has strong potential to strengthen instructional design and vocational curricula aligned with the demands of industrial technology.
