CREATION AND EFFICIENCY OF THE ISUZU D-MAX ABS BRAKE SYSTEM ELECTRICAL CIRCUIT SIMULATION SET

Abstract

The purpose of this research was to develop a simulation of the electrical circuit for the ABS braking system of the ISUZU D-MAX and to assess its effectiveness. This was conducted in the course "Vehicle Diagnostics and Troubleshooting" (Course Code: 17-4101-2406) and to evaluate the quality of instructional materials on ABS braking systems. The research also aimed to compare the learning outcomes before and after the students used the instructional materials. A sample group of 10 participants was selected through a purposive sampling method, and their satisfaction was assessed by 5 experts. The data were analyzed using the mean and standard deviation.

The research findings were as follows:

1. A simulation of the ISUZU D-MAX ABS electrical circuit was developed as a teaching tool for the course "Vehicle Diagnostics and Troubleshooting" (Course Code: 17-4101-2406) and was successfully used in this research.
2. The effectiveness of the ABS electrical circuit simulation for the ISUZU D-MAX was found to be high, with an E1 score of 93.60 and an E2 score of 92.00, which exceeded the set standard of 80/80. The simulation received high quality evaluations from 5 experts, with an average score of 4.42, indicating that the simulation is of good quality and suitable for use in teaching the course.
3. The comparison of learning outcomes, measured by pre- and post-test scores, showed significant improvement in learning outcomes after using the instructional materials, with statistical significance at the 0.05 level.
