Abstract

This study aims to analyze the effectiveness of interactive learning multimedia based on PowerPoint in improving students’ learning outcomes in the subject of Basic SMAW Welding Techniques at SMK IPT Karangpanas, Semarang City. The study employed a quantitative approach using a quasi-experimental design with a nonequivalent control group design type. The participants consisted of 60 tenth-grade students majoring in welding engineering, divided into two groups: an experimental group taught using interactive PowerPoint multimedia and a control group taught through conventional methods. Learning achievement data were collected using validated and reliable pretest and posttest instruments. Data were analyzed using t-tests and Normalized Gain (N-Gain) analysis. The results revealed a significant difference between the experimental and control groups, with mean posttest scores of 80.67 and 70.53, respectively (p < 0.001). The experimental group achieved an N-Gain value of 0.5639 (high category), while the control group achieved 0.3475 (moderate category). These findings indicate that interactive learning multimedia based on PowerPoint effectively enhances students’ learning outcomes. The media proved to be a practical, low-cost, and engaging alternative that bridges the limitations of conventional learning and supports vocational education improvement.

Abstract

This study analyzes the impact of Android-based learning media on improving the competence of reading external micrometer screw scales at SMK Negeri 1 Karangdadap, Pekalongan Regency. This study used a quasi-experimental two-group pretest-posttest design in two eleventh grade classes of Light Vehicle Engineering. Data were collected through cognitive tests. Media analysis used the Content Validity Ratio (CVR) and Percent Agreement (PA). Statistical analysis of student learning outcomes used a two-tailed t-test to test pre-test results, while to test post-test results used descriptive analysis, normality test, homogeneity test, right-tailed t-test, and N-Gain. The pre-test results showed that the two groups' results did not differ, indicating that their initial abilities were similar. The right-tailed t-test results indicated an increase in learning outcomes after using Android-based learning media. The magnitude of the increase was measured using N-Gain, with the experimental group achieving an N-Gain of 55.49% (moderate) and the control group achieving 22.04% (low). Based on the results of this study, the recommendation that learning using Android-based media is effective in improving learning outcomes.

Abstract

Autodesk Inventor software learning in manufacturing drawing subjects in vocational schools requires the support of interactive visual-based media to make complex technical materials easier for students to understand. The weakness of conventional methods in conveying this concept requires a breakthrough through the use of modern learning technology. This study focuses on evaluating the effectiveness of using PowerPoint-based multimedia to improve students' mastery of Autodesk Inventor. The research design used the purposive sampling method with pre-test and post-test models in two groups involving 60 students in grade XI of Mechanical Engineering at SMK Negeri 5 Semarang. The experimental group made use of interactive PowerPoint media, while the control group continued to use traditional methods. The results showed a significant increase in the experimental group with a p< value of 0.05 and an N-Gain value of 0.499 much higher than the control group with only 0.148. Thus, the use of interactive PowerPoint has proven to be effective in strengthening students' understanding of assembly engineering materials in a more interesting, flexible, and appropriate way for learning needs.

Abstract

Teaching material on vernier calipers with 1/128 inch and 1/1000 inch precision in Vocational High Schools (SMK) faces numerous challenges due to technical complexity and limitations in visualizing conventional media. This research aims to quantitatively analyze the effectiveness of Audio-Visual-based learning media in enhancing student comprehension. The study employed a pretest-posttest control group design experimental method involving 30 students from the Motorcycle Engineering expertise program at SMK Muhammadiyah 2 Semarang. The participants were divided into two groups: an experimental group (using multimedia) and a control group (using conventional methods). The research instruments were validated by media and material experts, with results indicating high feasibility and reliability (CVR > 0.75, percent agreement of 95% for media and 94% for material). The results of the effectiveness test prove that the average post-test score of the experimental group was significantly higher than the control group, evidenced by an independent samples t-test (t = 7.641, p = 0.000 < 0.05). The N-Gain analysis also showed a significant difference, with the experimental group experiencing an increase in the high category (68%), while the control group only reached the Low category (27%). This demonstrates that the use of interactive visual media is effective in improving students' conceptual understanding and measurement skills. From these results, it can be concluded that PowerPoint-based audio-visual multimedia is proven to be significantly effective in improving student learning outcomes, particularly for material that is visual and complex. This finding supports the implementation of multimedia learning theory within the context of vocational education.
