Abstract

Brakes are a key component in motor vehicle systems that play a vital part in decreasing the likelihood of accidents on the road. Improper component adjustment in the brake system, particularly with drum brakes, can cause the brakes to perform inefficiently. This research aimed to determine the effects of significant variations in drum brake and brake lining temperature on motorized vehicle braking efficiency. The brake lining gap size and the drum brake's temperature are controlled in this study's experimental setup.  From these various modifications, the main braking efficiency was verified using a brake tester. The brake lining gap is 0.3 mm, 1 mm, and 1.7 mm. Meanwhile, the brake drums' temperatures have been adjusted to 30, 90, and 150 degrees Celsius. The results show that braking efficiency decreases with increasing brake lining gap. The effectiveness of the drum brake decreases as the temperature rises. Meanwhile, the fluctuating brake lining spacing and temperature also affect braking efficiency. The brakes' effectiveness decreases with increasing distance between the drum brake's lining and temperature.

Abstract

School transportation in Sleman Regency faces various problems, including limited number of fleets, operational schedules that are not yet optimal, and the lack of adequate safety facilities. This condition means that some students are not served well and pose a risk to their safety and comfort during their trip. This research aims to evaluate the operational performance and services of school transportation, as well as formulate improvement strategies. The method used is a quantitative and qualitative approach through field surveys, interviews and distributing questionnaires. Service performance is analyzed using the Importance Performance Analysis (IPA) method, while development strategies are prepared through SWOT analysis. The research results show that at departure time, the load factor reaches up to 126.3% in corridor 1 and 118% in corridor 2, which indicates overloading with fleet availability of only 66.67%. Meanwhile, IPA analysis identified priority improvement indicators such as Emergency Response Information, Safety Equipment: glass breakers and APAR, and Safety Belts. The improvement strategy resulting in a SWOT matrix that is used in the short term includes preparing different return schedules and improving safety facilities such as providing fire extinguishers and glass breaking hammers. Long-term improvement strategies include adding corridors to school transportation services and digitizing reporting. It is hoped that this evaluation will become the basis for improving safer, more efficient and equitable school transportation services in Sleman Regency.
