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 aims to analyze the effect of integrating Autodesk Inventor and Morph 3D PowerPoint on students’ learning outcomes in the Engineering Drawing subject at SMK IPT Karangpanas. A true experimental design with a pretest–posttest control group was employed, involving an experimental class (n = 18) and a control class (n = 19). The test instrument was validated by experts and categorized as “highly feasible,” with strong reliability based on the percentage of agreement. The pretest results showed a significant difference between the two groups; therefore, the learning effectiveness analysis focused on the N-Gain score. Findings indicate that the experimental group achieved medium improvement, whereas the control group showed low improvement. The Mann–Whitney test was used due to the non-normal distribution of the data, resulting in U = 2.000, Z = –5.222, and p = 0.000, confirming a significant difference in the posttest scores between the groups. These results demonstrate that the integration of 3D-based visualization media enhances students’ spatial representation skills more effectively than conventional 2D media. Practically, this study offers an alternative instructional media that vocational teachers can use to clarify object-view concepts and improve the effectiveness of engineering drawing instruction.

Abstract

This study aims to analyze the aerodynamic performance of the 12-passenger electric car body design using a numerical simulation based on Computational Fluid Dynamics (CFD) with SolidWorks 2020 software. The vehicle body design was created using Autodesk Inventor and analyzed in a speed variation of 80 km/h to 100 km/h. The simulation results showed that the drag coefficient (Cd) value was in the stable range of 0.474 - 0.475 which indicates that the design has a fairly good aerodynamic performance for the shuttle vehicle class. Pressure distribution analysis shows an increase in maximum pressure and suction effect at the rear of the vehicle as speed increases. The airflow pattern also shows an increase in the turbulent zone (wake) behind the vehicle at high speeds which causes aerodynamic efficiency to decrease. Overall, this design shows optimal aerodynamic performance at medium speeds, and can be used as a reference for the development of future electric vehicles.

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.
