<![CDATA[Occupational Health and Safety (OHS) is an essential component of practical learning in the Electric Power Network Engineering (TJTL) program because students are exposed to electrical and workshop hazards. This study aimed to develop an OHS educational video and determine its feasibility, student response, and the increase in students’ understanding after use. The study employed Research and Development (R&D) with the 4-D model consisting of Define, Design, Develop, and Disseminate. Product validation involved three expert validators consisting of one media expert and two OHS experts, while user feasibility was assessed by three teacher practitioners. Student response involved 29 students, and the increase in understanding was examined using a one-group pretest-posttest design and N-Gain analysis. The mean feasibility score was 4.50 from the expert-media assessment and 4.82 from the practitioner assessment, both in the “very good” category. Student response reached a mean score of 4.78, also in the “very good” category. The mean N-Gain was 0.86, classified as high, indicating a substantial increase in test scores after the video was used. The findings support the use of the video as a contextual learning aid for OHS preparation before TJTL practical activities. However, the effectiveness evidence is limited because the study used one group without a comparison group and measured cognitive understanding rather than actual safety behavior.]]>
