One of the indicators for passing automotive training participants is the ability to solve automotive electrical problems. However, in reality, some of the participants in the automotive training center don't have such abilities. Engine Management System On Board (EMSOB) helped trainees to master skills in solving automotive electrical problems. The purpose of this study is to assess the effectiveness of EMSOB in improving skills in solving automotive electrical problems. This research employed a quasi-experimental non-equivalent pretest-posttest design, with a total sample of 42 automotive training participants at the State University of Malang. Research data were collected using tests, observations, and interviews. The data analysis technique used in this research was the Anova test. The research findings showed that the experimental class had better skills in solving automotive electrical problems than did the control class. This media has advantages including: being able to show the components of EPI, being able to display automotive electrical diagrams, making it easier to simulate electrical damage to EPI, and making it easier to perform a breakdown analysis. This media is equipped with modules, worksheets, and manuals, so that it has an impact on the effectiveness of EMSOB.
