Abstract

This study aims to analyze the effect of variations in air filter materials on torque, power, and fuel consumption in a Honda Beat 110 cc fuel-injected motorcycle. The air filter materials used in this study include paper, sponge, cotton, and wire mesh, each having different porosity characteristics that are expected to influence the amount of air entering the combustion chamber and consequently affect engine performance. This research employed an experimental method with a quantitative approach. Torque and power tests were conducted using a dynamometer, while fuel consumption was measured based on the amount of fuel used at specific engine speeds. The data were collected through repeated tests and analyzed statistically to determine the effect of air filter material variations on the observed parameters. The results are expected to reveal differences in torque, power, and fuel consumption among the various air filter materials and to identify the most effective filter material for improving engine performance while maintaining fuel efficiency.

Abstract

This study aims to develop a trainer-based learning medium for the brake system topic, determine the medium's feasibility, and assess its practicality. The study was motivated by the limited availability of practical learning media to assist students in understanding brake system concepts within the Automotive Fundamentals course at the Mechanical Engineering Education Study Program, Universitas Pendidikan Ganesha. The study employed the Research and Development (R&D) method using the 4D development model (Define, Design, Develop, and Disseminate); however, the research was conducted only up to the Develop stage. The research subjects consisted of two design experts, two manufacturing experts, 15 students for the small-group trial, and 30 students for the large-group trial. Data were collected via questionnaires and analyzed using quantitative descriptive analysis. The results indicated that the instrument's content validity score was 0.926, falling into the "very high" category. Validation results showed scores of 91.81% from design experts and 91.25% from manufacturing experts, classifying the learning medium as "highly feasible." Practicality test results yielded scores of 85.80% for the small group and 89.90% for the large group, placing the medium in the "highly practical" category. Thus, the trainer-based learning medium for the brake system topic is deemed valid, highly feasible, and highly practical for use in the Automotive Fundamentals course. Keywords: learning medium, trainer, brake system, automotive fundamentals, research and development.

Abstract

The predominance of conventional instructional practices in vocational education frequently constrains students' conceptual understanding and independent learning, particularly in the Power Tools topic of Basic Automotive Engineering. The development and evaluation of a learning medium utilizing Google Sites constituted the primary focus of this study, with the aim of fostering instructional experiences that are both more engaging and readily accessible. Guided by the Four-D (Define, Design, Develop, and Disseminate) model within a Research and Development (R&D) framework, this study evaluated the developed learning medium through expert validation alongside practicality assessments involving vocational high school students. Feasibility assessment placed the developed learning medium in the excellent category, supported by validation scores of 98.88% from the material expert and 90.62% from the media expert. Consistent results were obtained from the practicality evaluation, which recorded 85.88% in the small-group trial and increased to 89.66% in the large-group trial. These outcomes indicate that the developed media is pedagogically sound, user-friendly, and well-suited to facilitate interactive, flexible, and learner-centered instruction in vocational education.
