Abstract

The utilization of OP-AMP as controllers for temperature sensors plays a crucial role in both the manufacturing and automation sectors. Nevertheless, traditional learning approaches often fail to engage students, leading to diminished interest and lower academic performance. To address this issue, an interactive learning media based on Android technology is being developed, aimed at enhancing current teaching methods and improving students' understanding of OP-AMP applications in temperature sensor control. The objectives of this study are threefold: (1) to analyze the viability of the developed learning media, (2) to evaluate the impact on learning outcomes, and (3) to compare the learning improvements between this new media and traditional teaching methods. The research follows the ADDIE model, with data collection carried out via pre-tests and post-tests. Media feasibility was evaluated using CVR and CVI tests, while the cognitive test's validity was measured through Aiken's V and ICC. Data analysis employed a two-tailed t-test and N-Gain calculation. The study involved 72 eleventh-grade students from the Industrial Electronics Engineering program at SMK NU Ungaran. Results indicated that the Android-based interactive learning tool was highly effective, with a CVR above 0.75, an Aiken's V score of 0.90, and an ICC value of 0.797. Moreover, this learning media significantly enhanced students' academic performance, with a t-value of 30.234 and a p-value of 0.000. The experimental group saw a 74.4% improvement in learning outcomes, compared to 67.4% in the control group, demonstrating the media’s effectiveness in teaching OP-AMP applications.

Abstract

This study addresses challenges in the learning process of manufacturing engineering drawing elements, including insufficient student engagement, monotonous teaching methods, suboptimal learning media, and low student achievement, with 60% failing to meet the minimum competency standards. The primary objective of this research is to develop relevant, interactive multimedia to enhance learning outcomes in the design of complex assembly drawings, assess the feasibility of the media, evaluate student responses, and compare its effectiveness to other instructional methods in improving academic performance and student motivation.The research employed the ADDIE development model and was conducted at SMKN 1 Semarang, focusing on 11th-grade students in the Mechanical Engineering program. A total of 90 students from three classes participated, with each class receiving different instructional treatments. Students completed motivation questionnaires during the learning process, while those using interactive multimedia were asked to provide feedback on their experience with the media.The results indicate that the interactive multimedia developed is feasible and effective, as evidenced by expert evaluations and highly positive student responses. The application of interactive multimedia, integrated with a problem-based learning model, was more effective than video-assisted lecture methods and problem-based learning models. This study concludes that using interactive multimedia in conjunction with problem-based learning significantly enhances student learning outcomes and motivation. The innovation of this research lies in integrating interactive multimedia for teaching manufacturing engineering drawing elements

Abstract

This research is motivated by challenges in the learning process of motor starter topics, including low student engagement, a lack of teaching aids, suboptimal learning media, and previously low student performance, with 70% of individuals failing to meet the minimum passing grade. This study aims to develop Android-based AR-Card learning media for motor starter topics, assess the feasibility of the media, and compare its effectiveness with other teaching methods in improving learning outcomes and motivation. The research employs the ADDIE development model and was conducted at SMK Bina Nusantara Semarang with 42 eleventh-grade individuals majoring in Motorcycle Engineering. The sample consisted of two classes, each receiving different teaching treatments. The results show that the AR-Card learning media developed is deemed feasible based on expert evaluations. The implementation of AR-Card learning media proved to be more effective than conventional methods. The study concludes that AR-Card learning media significantly enhances both learning outcomes and motivation. The novelty of this research lies in the 3D visualization of motor starter components integrated into the learning media.

Abstract

Limited understanding of 2D and 3D sketching using Autodesk Inventor Drawing, constrained by conventional teaching methods and the lack of adequate learning modules, remains a significant challenge in the manufacturing design course for Mechanical Engineering students at SMK Negeri 5 Semarang. This issue directly impacts student learning outcomes. This study aims to develop a flipbook-based e-module to improve learning achievements, with its effectiveness analyzed through t-tests and N-gain tests. The research employed the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). An experimental method was applied using a pretest-posttest control group design, involving 64 students divided into an experimental class and a control class. The results indicated that the developed e-module, including its content, media, and assessment instruments, was deemed feasible for use. Statistical analysis revealed a significant improvement in the experimental class compared to the control class, as evidenced by a t-value greater than the critical t-table value (7.664 > 1.998). Furthermore, the N-gain test showed a moderate increase in the experimental class (0.56) compared to the control class (0.32), demonstrating an enhancement in student learning outcomes. This study highlights the positive impact of integrating technology into education and emphasizes the importance of innovative teaching methods in advancing student competencies in manufacturing design.

Abstract

This research aims to develop Advanced PowerPoint-based multimedia using the Problem-Based Learning (PBL) model and the ADDIE method. The material used in this research is workmanship signs. The objectives of this study are to: (1) test the feasibility of the developed multimedia based on Advanced PowerPoint and the Problem-Based Learning model, (2) evaluate the differences in learning outcomes between public and private vocational schools, and (3) Analyze the extent of improvement in learning outcomes among students who receive instruction using Advanced PowerPoint-based multimedia with the PBL model, compared to those who receive conventional instruction. Data were analyzed using one-way ANOVA, and the results showed a statistically significant difference between the tested groups. Furthermore, the LSD post hoc test revealed significant differences between pairs of groups, indicating that classes using Advanced PowerPoint-based multimedia with the PBL model achieved the highest learning outcomes. In contrast, private vocational school classes showed moderate N-Gain values. In conclusion, Advanced PowerPoint-based multimedia combined with the PBL model is effective in improving student learning outcomes in the topic of workmanship signs.
