Abstract

This study aims to develop Android-based learning media to improve students' abilities regarding the reduction type starter motor system and to determine the acquisition of learning motivation. The method used is pre-experimental design in the form of one-group pretest-posttest, while media development uses the ADDIE method. The population of this study were students who contracted electricity courses. The results of this study indicate an increase in the learning outcomes of the Pre-Test and Post-Test which is significant with the acquisition of the significance test using the t test with a significance value of 0.000, this increase is due to the use of android-based learning media that has been made. So that this learning media has a good impact on increasing students' insight in using technology, especially Android for learning uses. In addition, the students' learning motivation on average is in the category motivated by this media.

Abstract

This study aims to improve competence by providing knowledge and skills regarding maintenance and repair of electric vehicle technology (electric vehicle technology) to automotive productive teachers at Al Mufti Vocational School, Subang Regency. The training uses multiple approaches to simplify, strengthen and apply. The approach used is persuasive, collaborative and participatory. The method used is discussion, lecture, question and answer, demonstration and practice on electric cars, electric motorcycles and decomposed components. The level of achievement based on knowledge and skills carried out by post-test and pretest as well as performance tests shows the achievement of competence of 80 percent, so it is hoped that participants can transfer this electric vehicle technology to students in anticipation of the development and transition of driving technology from internal combustion engines (ICE) to electric drive.

Abstract

The internal combustion engine is a gasoline-powered internal combustion engine that is widely used in the world of transportation. Therefore, everyone is starting to think about developing alternative fuels that are fuel efficient, easy to upgrade, and better in terms of emissions. Vehicles with electric motors are one of the right solutions because they are more environmentally friendly and do not cause pollution when used. In this study, we will discuss the performance of the brushless DC electric motor that is applied to the Go-kart based on the voltage, current, and electrical power that occurs. The method used is measurement using software and experimental simulations. Based on the test results using Votol_V3 Voltage, current, power, and rotation per minute (rpm) have a relationship, the higher the rpm on the mid-drive type electric motor, the greater the current and power required.

Abstract

Rapid advancements in hybrid vehicle technology demand significant adjustments in vocational education to equip students with relevant competencies. This study investigates the effectiveness of a hybrid motorcycle prototype as an innovative learning media to improve student learning outcomes in vocational automotive education. Employing a pre-experimental one-group pretest-post-test design, the research involved 30 Grade XI Automotive Engineering students at SMK Negeri 1 Cisarua. Participants underwent a pretest, followed by four prototype-based learning sessions, and a post-test. Data were analysed using descriptive statistics, paired-samples t-test, and normalized gain (g). Results demonstrated a substantial improvement in learning outcomes, with the mean score increasing from 58.5 to 82.67 (mean gain = 24.17 points; t(29) = 8.805, p < 0.001; Cohen's d = 1.61), indicating a very large effect size. The normalized gain of 0.55 suggests medium effectiveness based on Hake's classification. Furthermore, 90.0% (27/30) of students achieved scores ≥75 post-intervention, compared to 23.3% (7/30) beforehand. Aligning with Edgar Dale’s Cone of Experience, these findings highlight that direct, hands-on engagement enhances comprehension and retention. The study concludes that hybrid motorcycle prototypes offer a cost-effective, practical, and scalable solution to bridge the theory-practice gap in vocational automotive education, especially in motorcycle-dominant contexts. Recommendations include integrating prototype-based learning into the Merdeka Curriculum and expanding its application to other technical domains.
