<![CDATA[This study aims to: (1) test the feasibility of a deep learning approach-based tune up job sheet as a learning medium; and (2) examine the effectiveness of the product in improving student achievement. Using the Research and Development (R&D) method with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), this study involved class XI TKRO students at SMK Muhammadiyah Petanahan divided into an experimental group (n=20) and a control group (n=20). Data were collected through observation, feasibility questionnaires (Likert scale), and learning achievement tests (pre-test and post-test). The results showed: (1) the job sheet was declared highly feasible and valid based on expert assessments — media expert 87.5% (Very Valid), material expert 80.0% (Valid), small group trial 80.0% (Valid), and large group trial 82.3% (Very Good); (2) the job sheet was effective in significantly improving student learning achievement based on the Independent Sample t-Test (t = 5.220 > t-table = 2.024; p = 0.000007 < 0.05), with the experimental group achieving a post-test mean of 77.25 (KKM completion rate rising from 35% to 75%), outperforming the control group which only obtained a mean of 62.00 (KKM completion 5%).]]>
