<![CDATA[The practicum learning process in vocational education requires instructional media that support students in understanding work procedures systematically and independently. However, the printed jobsheets used in forward-reverse circuit learning still have limitations in visualization and interactivity. This study aims to develop an electronic jobsheet (e-jobsheet) for forward-reverse circuit materials and determine its validity, practicality, and effectiveness. The research employed the Research and Development (R&D) method using the Instructional Development Institute (IDI) model, consisting of three stages: define, develop, and evaluate. The participants included expert validators, subject teachers, and 30 eleventh-grade students in the Electrical Power Installation Engineering program. Data were collected through observations, interviews, questionnaires, and learning outcome tests. The findings revealed that the developed e-jobsheet achieved material validity of 75% (valid), media validity of 85.93% (very valid), and language validity of 94.65% (very valid). The practicality test showed a score of 91.67% (very practical). In addition, the effectiveness test indicated an improvement in student learning outcomes, with the average pretest score increasing from 55 to 88.1 in the posttest and producing an N-gain score of 0.78 in the high category. Therefore, the developed e-jobsheet is considered valid, practical, and effective for supporting digital-based and student-centered practicum learning in forward-reverse circuit materials.]]>
