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.

The case study from this study found findings that showed that the Access by KAI application in October 2024 received a rating of 2.5/5.0, this value is the lowest rating of other train ticket booking applications such as Traveloka and tiket.com which received a rating of 4.8/5.0 on the play store application store, therefore the researcher wants to know "how customer satisfaction is using the Access by KAI application". The researcher wants to conduct research on this problem, by developing an empirical method to explain the variables that affect customer satisfaction by using data obtained from the play store app store and distributing questionnaires to the general public randomly. The test was carried out using the Statistical Product and Service Solutions (SPSS) approach. The test results found that the quality of service was proven to be significant and positive to customer satisfaction, customer assessments were not proven to have a significant effect and negative on customer satisfaction, promotions were not proven to be significant and negative to customer satisfaction.

Occupational Safety and Health (OSH) is a crucial aspect of land surveying practices conducted by vocational high school students. The risk of accidents, such as falls, being buried by soil, and exposure to extreme weather conditions, necessitates the optimal implementation of OSH awareness and compliance. This study aims to analyze the integration of student awareness and compliance with OSH in land surveying practices. The research employs a quantitative approach using multiple linear regression analysis. Prior to analysis, the data were tested for (1) normality, (2) homogeneity, and (3) linearity. The study population consists of 105 students from the Construction and Housing Engineering program at SMK Negeri 3 Semarang, selected through a total sampling technique. Data were collected through questionnaires, observations, and interviews, then analyzed using SPSS. The results indicate that student awareness and compliance significantly and simultaneously influence OSH implementation, contributing 78%. The correlation analysis reveals a strong relationship of 88% between the variables. Students with high awareness and compliance demonstrate greater discipline in adhering to OSH procedures in the field. These findings suggest that enhancing education, providing adequate safety facilities, and enforcing strict supervision can further improve OSH implementation in land surveying practices within vocational school environments.
