Abstract

This study aims to determine the effectiveness of using video tutorial media in improving student learning outcomes on the material of welding machine parts functions at SMK IPT Karangpanas, Semarang. The research method used was a true experiment with a pretest-posttest control group design. The research sample consisted of 44 students of class X Machining Engineering who were randomly divided into an experimental group of 22 students and a control group of 22 students. The data collection instrument used was a multiple-choice objective test given before and after treatment. The experimental group received learning using video tutorials, while the control group followed conventional learning. The results of the independent sample t-test on the post-test showed a significant difference between the two groups (p < 0.001), with an average score of 85.23 for the experimental group and 68.86 for the control group. The normality and homogeneity tests met the requirements of parametric analysis. The results of the N-Gain analysis showed a high increase in the experimental group (0.7670) and a moderate increase in the control group (0.4741). These findings indicate that video tutorials are effective in improving students' conceptual understanding and technical skills and are suitable for use as an alternative learning strategy in vocational education.

Abstract

This study aims to: 1) analyze the feasibility of PowerPoint multimedia on the topic of lathe machine parts; 2) test the effectiveness of PowerPoint multimedia on the topic of lathe machine parts; and 3) analyze the improvement in student learning outcomes after the application of PowerPoint multimedia on the topic of lathe machine parts. The method used in this study is a quantitative approach using the Nonequivalent Control Group Design pattern experimental method. The data collection technique in this study used a test. Post-test data analysis techniques include descriptive analysis, normality test, homogeneity test, right-tailed t-test, and N-Gain test. The results of the validity and reliability tests indicate that the developed multimedia is suitable for use in learning. Based on the results of the t-test, the t-value obtained was 10.013, greater than the t-table of 1.699, indicating a significant difference between the experimental group and the control group. The average post-test score of the experimental class reached 80.00 (78%) with a high category, and the N-Gain analysis showed a greater improvement in learning outcomes compared to the control group.

Abstract

Learning assembly techniques in Computer-Aided Design (CAD) subjects in Vocational High Schools (SMK) requires media that supports interactive visualization to facilitate understanding of complex technical concepts. The limitations of conventional media in bridging this need encourages innovation in the use of learning technology. This study aims to analyze the effectiveness of flipbook-based media in improving students' understanding of assembly engineering material. The method used was a quasi-experimental with a two-group pretest-posttest design, involving 40 eleventh-grade students of Mechanical Engineering at SMK Negeri 5 Semarang. The experimental group used flipbooks as a learning medium, while the control group received conventional learning. The results showed a significant increase in the experimental group based on posttest scores (p < 0.05) and an N-Gain value of 64.15%, compared to the control group, which only achieved 43.27%. Thus, flipbooks proved effective in improving students' understanding of assembly engineering material in a more flexible, engaging, and contextual way.

Abstract

The low achievement of students' cognitive learning outcomes in the material of the function of milling machine parts indicates the need for innovation in learning media that is more interactive and adaptive to the characteristics of vocational high school students. This study aims to evaluate the effectiveness of the use of interactive e-modules in improving student learning outcomes in the subject of Machining Engineering. This study uses a quantitative approach with a quasi-experimental design of the Nonequivalent Control Group Design type involving two classes of XI Machining Engineering at SMK Negeri 1 Karangawen as the experimental group and the control group. The main instrument is a 20-item multiple-choice test that has been validated using the Content Validity Ratio (CVR) and its reliability tested with the Intraclass Correlation Coefficient (ICC). Data analysis included normality test, homogeneity test, two-tailed t-test on pre-test, one-tailed t-test on post-test, and N-Gain analysis. The results showed that there was no significant difference between the two groups in the pre-test (p = 0.762), but there was a statistically significant difference in the post-test (p < 0.001), with an average value of 81.25 for the experimental group and 72.50 for the control group. The average N-Gain of the experimental group reached 0.5515, higher than that of the control group at 0.3543. These findings indicate that interactive e-modules are effective in improving students' cognitive learning outcomes on conceptual and visual materials. Thus, interactive e-modules are worthy of recommendation as alternative digital learning media in vocational education, especially to strengthen the technical understanding of vocational high school students in accordance with the demands of technological developments and the needs of the industrial world.
