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.

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.
