Abstract

The problem of this research was the limitation of learning media for speed sensors in the Ototronics laboratory, which has an impact on three critical aspects in the teaching and learning process: (1) limited students gain practical experience, (2) decreased student motivation and participation, and (3) the difficulty of lecturers demonstrating material comprehensively in the Sensors and Transducers course. This research aimed to design a mini trainer speed sensor as an innovative learning media to overcome the limitations of practicum media in the Ototronics laboratory, impacting the student learning experience. The research used a quantitative-descriptive and Structural Equation Modeling-Partial Least Squares (SEM-PLS) validation involving 7 learning media experts. The results showed highly significant design validity. The didactic aspect proved to give the most superior contribution to improving the effectiveness of learning media. This research successfully addressed three main problems: student’s limited practical experience, decreased participation motivation, and lecturers’ difficulty demonstrating the material. The results confirm that this particular learning media effectively addresses three critical impacts in the teaching and learning process: student’s limited practical experience, decreased participation motivation, and lecturers’ difficulty demonstrating the material, thus opening up opportunities for developing transformative interactive learning media in technical vocational education.

Abstract

Replacement analysis is used to evaluate whether the currently used asset needs to be replaced with a newer and more economically efficient one. This study aims to determine the feasibility of replacing the official service vehicles at Universitas Negeri Padang from conventional vehicles to electric vehicles based on an economic analysis. Data on official service vehicles were collected from the facilities and infrastructure division of Universitas Negeri Padang, while data on electric vehicles were obtained through a literature review. Data processing was conducted using the Equivalent Uniform Annual Cost (EUAC) method. The results indicate that replacing the official service vehicles at Universitas Negeri Padang from conventional vehicles to electric vehicles is not yet feasible.

Abstract: This study aims to analyze the influence of simulator trainer media on the learning outcomes of the motorcycle starter system compared to conventional lecture methods. Using a quantitative experiment method with a one group pretest-posttest design, the study involved 25 students in class XI TSM in the even semester of the 2024/2025 school year at SMKN 1 Bonjol. Data were collected through validated multiple-choice objective tests: 20 items for the pretest and 30 items for the posttest. Data analysis was conducted using the paired sample t-test. The results showed a significant increase from the average pretest of 68.8 to 83.28 in the posttest after the implementation of the simulator media trainer. The statistical test obtained a t-count of 9,438 > t-table of 2,064 with an influence rate of 21%, showing a significant difference in α = 0.05. It was concluded that the simulator trainer media can improve student learning outcomes on motorcycle starter system materials, providing a more concrete and interactive learning experience than conventional lecture methods.Keywords:  trainer simulator, learning outcomes, starter system, motorcycle, technical education.

Abstract: This study aims to analyze the effect of Pertamax and methanol blends on fuel consumption and economic efficiency of a Honda Beat Street 110 cc motorcycle. The research employed a quantitative experimental method using the Taguchi approach, with four factors: fuel blend percentage (0%, 10%, 20%), engine speed (2000 rpm, 2500 rpm, 3000 rpm), vehicle speed (40 km/h, 60 km/h, 80 km/h), and engine temperature (70 °C, 90 °C, 110 °C). The results showed that the lowest fuel consumption was achieved with 0% methanol at 2500 rpm and 90 °C, recording 0.1378 ml/s, while the highest consumption occurred with 20% methanol at 2000 rpm and 90 °C, reaching 0.2500 ml/s. In terms of economic efficiency, the optimal condition was obtained with 10% methanol, 2500 rpm, 80 km/h, and 70 °C, resulting in the lowest operational cost of IDR 8,646/km. Thus, blending Pertamax and methanol at certain proportions can improve vehicle economic efficiency and serve as an alternative to reduce fuel expenses.Keywords: Pertamax, Methanol, Fuel Consumption, Economic Efficiency, Taguchi
