Abstract

This study aims to determine: (1) the level of students’ understanding of the PGM-FI (Programmed Fuel Injection) system; and (2) the effect of PGM-FI system understanding on tune-up practical outcomes among Class XI TSM students at SMK Pancasila 1 Kutoarjo. A quantitative approach with an ex post facto correlational design was employed. The subjects were 30 Class XI TSM students in the 2025/2026 academic year. Data were collected using a 40-item written test on PGM-FI understanding and a 5-component practical performance observation sheet. Instruments were validated using Pearson Product Moment correlation (r-table = 0.361; all items valid) and reliability-tested using Cronbach’s Alpha (α = 0.898) for the written test and Cohen’s Kappa (κ = 1.000) for the practical sheet. Prerequisite tests confirmed normality (K-S sig. = 0.110 > 0.05) and linearity (Deviation from Linearity sig. = 0.117 > 0.05). Results showed that PGM-FI understanding was in the high category (mean = 32.57; 81.43%), as was practical performance (mean = 80.67; high category). Simple linear regression and Pearson correlation confirmed a positive and significant effect of PGM-FI understanding on tune-up practical outcomes (r = 0.493; R² = 0.243; t = 3.002; sig. = 0.000 < 0.05), with PGM-FI understanding contributing 24.3% to the variation in practical outcomes. The remaining 75.7% is attributable to other factors such as practical experience, motivation, facilities, and individual student characteristics.

Abstract

This research aims to produce interactive learning media for the periodic maintenance competency at SMK Ma'arif 6 Ayah, assess the feasibility of interactive multimedia learning media for the periodic maintenance competency, and measure the improvement in student learning outcomes following the use of interactive multimedia learning media for the periodic maintenance competency. The development of the interactive learning media employed a Research and Development (R&D) research method. Small-scale field trials were conducted with 12 students, and large-scale field trials were conducted with 32 Grade XII students of the Light Vehicle Engineering study program at SMK Ma'arif 6 Ayah. The trial results fell within the very feasible category, with the following details: material expert evaluation yielded a score of 88.25% (very feasible); media expert evaluation yielded a score of 87.75% (very feasible); small-scale student trials yielded a score of 89% (very feasible); and large-scale student trials yielded a score of 89.75% (very feasible). Based on these results, it can be concluded that the interactive multimedia-based learning media for the periodic maintenance competency is very feasible for use as a learning medium and is effective in improving student learning outcomes. This medium can therefore serve as an alternative solution in automotive practical learning, particularly at SMK Ma'arif 6 Ayah, and may be adapted for other subjects requiring practice-based procedural understanding.

Abstract

This study aims to determine the level of understanding and knowledge of Class X TKR students at SMK YPT Purworejo regarding the types, functions, and basic use of automotive hand tools. The research employs a quantitative descriptive method using a cross-sectional survey design. The subjects were all 30 Class X TKR students in the 2025/2026 academic year (total sampling). Data were collected through a 30-item multiple-choice cognitive test validated with Pearson Product Moment correlation and reliability-tested with Cronbach’s Alpha, complemented by structured observation (15 aspects, scale 1–4) and guided interviews. Data were analyzed using descriptive statistics and percentage-frequency distribution with five classification categories: Very Good (81–100%), Good (66–80%), Fair (56–65%), Poor (41–55%), and Not Good (25–40%). Results showed a mean cognitive test score of 69.4 (Good category), with distribution: 3 students (10.0%) Very Good, 9 students (30.0%) Good, 10 students (33.3%) Fair, 7 students (23.3%) Poor, and 1 student (3.3%) Not Good. The observation mean was 78.5% (Good category), with the highest scores on basic tool recognition and work attitude (85.0–90.0%), and the lowest on precision measuring instruments (62.5%). Key constraints identified include: limited availability of practical tools, monotonous teaching methods, and diverse student backgrounds. These findings provide an empirical baseline for improving hand tool competency learning in vocational automotive education.

Abstract

This study was motivated by the need to improve students’ learning outcomes in disc brake system material, which requires an integrated understanding of theoretical concepts and practical skills. The demonstration method provides students with concrete learning experiences through direct observation of components, working principles, and disc brake system inspection procedures. This study aimed to determine the improvement in learning outcomes among students taught using the demonstration method and conventional learning and to examine differences in learning outcome improvement between the two groups. A quantitative approach with a quasi-experimental method and a nonequivalent control group design was employed. The study involved 72 students in Grade XI of the Light Vehicle Engineering program at SMK Muhammadiyah Lemahabang in the 2025/2026 academic year, consisting of 36 students in the experimental class and 36 students in the control class. Data were collected through tests, observation, and documentation and analyzed using validity, reliability, normality, homogeneity, paired-sample t-test, independent-sample t-test, and N-Gain analysis. The results showed a significant improvement in the experimental class (p < 0.05), with an average N-Gain of 75.3266%, categorized as effective, compared with 37.9182% in the control class, categorized as less effective. The independent-sample t-test also indicated a significant difference between the two groups (p < 0.05). These findings demonstrate that the demonstration method is more effective than conventional learning in improving students’ learning outcomes in disc brake system material.

Abstract

This study is motivated by the low critical thinking skills and cooperative attitudes among class XI TKR students at SMK Bunda Satria Wangon in the subject of Pemeliharaan Sasis dan Pemindah Tenaga Kendaraan Ringan (PSPTKR), particularly on the power transmission system material, due to the use of teacher-centered conventional learning models. This study aims to determine the difference in students' critical thinking skills before and after implementing the Project Based Learning (PjBL) model, and to determine whether student cooperative attitudes meet the good criteria through this model. The research method used is quantitative with a Nonequivalent Control Group Design. The research population comprised all class XI TKR students at SMK Bunda Satria Wangon, with a sample of 38 students in the experimental class and 36 students in the control class (74 students total). Data collection of critical thinking skills used a test instrument of 10 essay questions, while cooperative attitude data were collected through a questionnaire. Data analysis included descriptive analysis, prerequisite tests (normality and homogeneity), and inferential analysis using Paired Samples t-Test and Independent Samples t-Test. The results showed that there was a significant difference in students' critical thinking skills before and after using the PjBL model in the experimental class (t = 41.218, Sig. < 0.001). The experimental class showed a gain absolute of 21.21 points compared to 14.39 points in the control class. N-Gain scores for both classes were in the moderate category (experimental: 0.590; control: 0.587). Independent samples t-test results also showed a significant difference between the two classes (t = 6.335, Sig. = 0.000). These findings confirm that the PjBL learning model is effective in improving critical thinking skills and fostering cooperative attitudes among students on the power transmission system material.
