The improvement of public transportation service quality is highly influenced by the competence, performance, and behavior of drivers, who serve as the frontline of service delivery. The Public Transport Driver Certification Training (SPAU) is conducted to enhance professionalism, driving safety, and service ethics; however, its effectiveness in the field needs to be evaluated comprehensively. This study aims to assess the effectiveness of SPAU training on drivers’ performance and behavior, as well as its impact on passenger satisfaction, using an integrated analytical approach. The research employs a quantitative approach with data triangulation from drivers, their direct supervisors, and passengers. Analyses are conducted using Structural Equation Modeling (SEM) to examine causal relationships among variables, Importance Performance Analysis (IPA) to identify service attributes requiring priority improvement, and the Customer Satisfaction Index (CSI) to measure overall passenger satisfaction. The results indicate that competencies acquired from the training significantly influence improvements in drivers’ performance and behavior, which in turn positively affect passenger satisfaction. IPA analysis reveals several service attributes that still require improvement, while the CSI score shows that overall passenger satisfaction falls within a good category. These findings underscore the importance of strengthening the curriculum, providing post-certification guidance, and implementing continuous monitoring to ensure the sustainability of the training’s impact on public transportation service quality.

The widespread use of overloaded and overdimensioned freight vehicles (ODOL) has become a serious issue, affecting not only road infrastructure but also the technical components of vehicles, such as the chassis and suspension systems. This study aims to directly analyze the impact of excessive load and dimensions on the durability of the chassis and leaf springs as part of the vehicle’s suspension system. The main problem examined is the extent to which ODOL conditions contribute to technical damage in the chassis and leaf springs.This research adopts an experimental approach by collecting data through field observations, driver interviews, and static load simulations using the Finite Element Analysis method with SolidWorks software. Simulations were conducted on the chassis and leaf springs of an open-bed truck with a 1.2 axle configuration, using three load variations (10%, 20%, and 30% over the vehicle's Gross Vehicle Weight Rating or GVWR). The simulations also aimed to identify the point at which the chassis and leaf springs experience material failure or fracture. The results show a significant increase in stress and displacement in both the chassis and leaf springs under 10%, 20%, and 30% overload conditions. Furthermore, the factor of safety values indicate a declining level of material safety as the load increases. Material failure in the chassis occurred at 55% overload, while the leaf springs failed at 150.7% overload. Based on observations, interviews, and simulation results, this study reinforces the importance of enforcing regulations on vehicle weight and dimensions. In addition to damaging infrastructure, ODOL vehicles significantly compromise the structural integrity of the chassis and suspension system, leading to increased vehicle maintenance costs. This research is expected to serve as a technical reference for business operators and policymakers in supporting the Zero ODOL program and as a basis for developing more evidence-based road safety policies.

The use of vehicles using diesel engines is increasing and has a direct impact on increasing exhaust emissions, especially particulate matter (PM), which is harmful to health and the environment. This study aims to analyze the installation of a honeycomb Diesel Particulate Filter (DPF) made of galvalum on exhaust emissions and engine temperature in a Mitsubishi L300 vehicle. The DPF was designed using galvalum material with a square honeycomb configuration and glasswool variations of 50, 100, and 150 grams. The test was conducted experimentally by comparing conditions without DPF and after DPF installation, including testing exhaust emissions, engine oil temperature, radiator water temperature, and exhaust manifold temperature. The installation of a diesel particulate filter (DPF) can reduce exhaust emissions by up to 37.1% at DPF 150 variations. DPF installation also relatively increases the temperature of radiator water, engine oil, and exhaust manifold in diesel engines. The largest temperature increase in exhaust manifold temperature is up to 8.02% compared to without using DPF at idle conditions. This temperature increase is caused by the honeycomb and glasswool structures that can create obstacles to the flow of exhaust gases. When the engine speed reaches 2000 rpm, there is an increase in exhaust manifold temperature of up to 15.09% compared to idle speed. This increase is due to faster engine speed so that combustion heat also increases.
