Abstract

The rapid growth of the electric vehicle industry in Indonesia has created an urgent demand for a technically competent workforce, particularly in mastering lithium-ion battery technology as the core component of electric vehicles. This study investigates the extent to which students' level of understanding of lithium-ion battery concepts influences their perceptions of career readiness in the electric vehicle industry. A quantitative approach with a correlational survey method was employed, involving 60 students as respondents. Data were collected through a questionnaire that had undergone validity and reliability testing, and subsequently analyzed using simple linear regression. The findings reveal that students' understanding of lithium-ion battery concepts has a significant effect on their career readiness perceptions, with a coefficient of determination of 52.5% and an F-value of 64.026 at a significance level of 0.000. These results suggest that the stronger a student's grasp of battery technology, the greater their confidence in entering the electric vehicle sector. This study provides empirical evidence that strengthening vocational and engineering education curricula, particularly in battery technology content, is a crucial step in preparing a competitive workforce for the continuously expanding electric vehicle industry.

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.
