Abstract

Understanding welding defect analysis is a crucial competency in vocational welding education, especially in ensuring the quality and safety of welding outcomes. However, many students struggle to master this material due to the lack of interactive and adaptive learning media. This study aims to develop and implement an electronic module (e-module) to enhance student learning outcomes in Shielded Metal Arc Welding (SMAW) defect analysis at SMK N 5 Semarang. The research uses a Research and Development (R&D) approach based on the 4D model: Define, Design, Develop, and Disseminate. A one-group pre-test post-test design was used, involving 33 Grade XI Mechanical Engineering 2 students. The e-module was validated by experts and classified as "Valid" in terms of content, media, and assessments. Students' average scores increased from 40.61 in the pre-test to 78.64 in the post-test. Statistical analysis using the Wilcoxon Signed-Rank Test and paired t-test showed a significant difference (p < 0.001). The average N-Gain score was 0.63, indicating a moderate improvement. The results confirm that the e-module is both feasible and effective. It enhances students’ conceptual understanding and supports independent, technology-based learning aligned with the characteristics of digital-native learners.

Abstract

The problem with learning Occupational Health, Safety, and Environmental Protection (OHS-EP) and Industrial Work Culture is that most students show a lack of enthusiasm in participating in lessons and struggle to understand the teaching material, particularly in important aspects such as the application of OHS-EP procedures, the use of personal protective equipment (PPE), and understanding the principles of industrial work culture. This study aims to apply and analyze the feasibility and effectiveness of an Android-based E-Module to improve the cognitive abilities of vocational school students on the subjects of OHS-EP and Industrial Work Culture. The research follows the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). A pre-experimental method with a two-group pretest-posttest design was employed, comparing an experimental class and a control class consisting of 70 students. The results indicate that the assessment of the material, media, and test instruments for the E-Module is deemed suitable for use. Statistical analysis reveals a significant improvement in the experimental class compared to the control class after the intervention. The results of the N-Gain test show that the experimental class experienced a 53.4% improvement (moderate category), while the control class showed only a 21.5% improvement, indicating enhanced cognitive abilities among the students. This study emphasizes the positive impact of technology on education and reinforces the importance of innovative teaching methods to improve cognitive abilities in students.

Abstract

The availability of innovative, interactive, and student-centered learning media to facilitate the understanding of marketing techniques, air conditioning, and cooling systems, particularly the components of refrigeration installation systems, remains insufficient. It happened since interactive and contextual learning media at school were limited. This study aimed to develop and apply an E-module as an effective learning medium to improve students’ learning achievement in the element of refrigeration installation. The presented research adopted the ADDIE, which comprises five steps: analysis, design, development, implementation, and evaluation. The subjects of this study were XI-grade students from two different vocational schools in Central Java. The participants were divided into an experimental group (utilizing an E-Module) and a control group (receiving conventional instruction). The instruments employed included expert validation sheets, practicality questionnaires, and learning outcome tests. The data showed that the E-module was very feasible, with a practical score gained 94% and the N-Gain of the experiment class achieved 0.74 (high level category). Furthermore, the t-test showed a difference between the experimental and control classes. In conclusion, E-module was declared very feasible, practical, and effective enough to be used in vocation learning, especially on improving students’ knowledge in refrigerator installation system of cooling technique and air conditioning system such as sytem component of instalation refigerator, conceptual knowledge (understanding colling and workflow sytem), and procedural knowledge (explaining the steps for installing and maintaining the refrigeration system).

Abstract

The nozzle tester, which is commonly used in the automotive engineering program at SMK N 1 Kedungwuni, is in a leaking condition, limiting its effectiveness in supporting learning and consequently affecting student learning outcomes. This issue is the main reason for conducting research on the development of a nozzle tester using a recycled jack, aimed at enhancing the learning of conventional diesel engine systems. This study employs a Research and Development (R&D) approach with the ADDIE model for development. The research method used is a pretest-posttest group design. The findings of the study include: (1) the developed teaching tool was considered feasible by media and subject matter experts, with content validity ratio (CVR), content validity index (CVI), and percentage of agreement (PA) analyses; (2) product trials showed a high level of effectiveness, demonstrated by the Independent Sample t-Test, where the N Gain Score resulted in a significant (2-tailed) value; and (3) the reproducibility coefficient (Kr) and scalability coefficient (Ks) both indicate that the application of the nozzle tester in the conventional diesel engine system learning process is very practical. The conclusion of this study is that the nozzle tester can significantly improve the learning outcomes of conventional diesel engine systems.

Abstract

A common issue in the practical learning of light vehicle electrical systems is the inadequate availability of voltage sources, particularly batteries, in terms of quality and quantity. As a result, most students, after being assessed, receive scores that do not meet expectations. To address this issue, an alternative voltage source is needed to replace the battery, ensuring that the practical learning process for the light vehicle electrical system runs smoothly. This study aims to develop a practical tool using a computer power supply to improve the learning outcomes of the light vehicle electrical system. The research employs the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The experimental method used involves a pretest and posttest group, comparing the experimental class and the control class, consisting of 72 students. The results show that the practical tool using a computer power supply has a significant impact on the learning outcomes of the light vehicle electrical system, as analyzed through a one-tailed t-test. Based on N-Gain Score calculations, the tool is effective in improving learning outcomes, achieving high-level results. The conclusion of this research is that the practical tool using a computer power supply can replace the role of a battery as a voltage source in light vehicle electrical system practices.

Abstract

Proving the validity of research instruments is very important. The success of research is largely determined by the validity or invalidity of the instruments used. The validity of the instrument greatly affects the accuracy of the measurement results. The basic principle of research instruments is to measure what will be measured. The purpose of proving the validity of the instrument is to ensure that the instrument reflects the theoretical concept. Proof of validity in this study includes instrument content validity, item validity, construct validity. Proof of content validity using the Aiken V formula. This research involved 7 expert judgements to validate the developed ethics instrument. The results of data analysis obtained the coefficient value V is valid. Proof of item validity using the pearson correlation product moment formula with the criteria r count> r table. The study involved 386 students so that the criterion r count> 0.113 with a significance of 0.05. Proof of construct validity using the exploratory factor analysis method and all items are valid by obtaining a KMO value of 0.811> 0.5 and each item obtains an anti-image correlation value> 0.5 and based on the analysis of Initial Eugenvalues Comulative terbahadap 20 statement items obtained five components whose value is > 1.
