Development and feasibility testing of throttle-by-wire trainer media for motorcycle engineering learning

Abstract

This study aims to develop and evaluate the feasibility of a learning media in the form of a Throttle By Wire (TBW) electrical system trainer for motorcycle engineering education. The research employed a Research and Development (R&D) approach using the DDD-E model, and its effectiveness was tested through a pre-experimental one-group pretest-posttest design. The research subjects were vocational high school students in the automotive engineering program. The instruments used included expert validation sheets, student response questionnaires, and objective tests to assess learning outcomes. The validation results showed that the TBW trainer was considered very feasible by experts with a 100% feasibility score. Students’ responses were also categorized as very good with an acceptance rate of 78.94%. The paired sample t-test obtained a significance value of 0.000 (≤0.05), indicating a significant difference between pretest and posttest results. The N-Gain analysis reached a score of 0.89, which falls into the high category, demonstrating highly effective improvement in student learning outcomes. Based on these findings, the TBW trainer is proven to be both feasible and effective in enhancing students’ learning achievements. This media is recommended for broader implementation in teaching modern motorcycle electrical systems, particularly to bridge the gap between theoretical knowledge and practical application.
