Abstract

Occupational Health and Safety (OHS) is a crucial aspect of manufacturing industry operations, particularly in activities involving interactions between humans, machines, and materials. This study aims to identify, evaluate, and classify potential hazards and the associated risk levels in various work processes, including Picking Differential Carrier, Small Part Preparation, Brake Assembly & Retainer Press, Axle Shaft & Brake Install, and Nut Brake Tightening. The analysis method employs a systematic approach to different types of hazards—chemical, physical, mechanical, and ergonomic—followed by an assessment of probability and impact levels. The results indicate that most hazards fall within the "unlikely" to "possible" probability categories, with risk levels ranging from low to moderate. The dominant hazards identified stem from mechanical factors, such as the risk of being struck or scratched by materials, and ergonomic factors related to non-ergonomic working postures. Implemented controls include the use of personal protective equipment (PPE), enforcement of work instructions, installation of visual warning systems, and technical modifications to machinery. It can be concluded that risk management has been conducted effectively; however, continuous evaluation is necessary to ensure a safe, healthy, and productive working environment for employees.

Abstract

Bus Rapid Transit (BRT) systems play a crucial role in providing efficient and sustainable urban mobility, yet service quality often faces challenges that lead to passenger dissatisfaction. This study focuses on BRT Trans Jateng Corridor 7, which has received a considerable number of complaints regarding service reliability, comfort, and punctuality. The main objective of this research is to improve passenger satisfaction by applying the Six Sigma methodology to identify, analyze, and reduce the root causes of service-related complaints. Using the DMAIC (Define, Measure, Analyze, Improve, Control) framework, data were collected through complaint reports, passenger surveys, and operational performance indicators. Statistical analysis and cause-effect diagrams were employed to pinpoint critical factors influencing complaints, including bus frequency, driver performance, ticketing efficiency, and infrastructure support. The findings indicate that the application of Six Sigma significantly reduced recurring complaints, particularly in the areas of schedule adherence and service responsiveness, leading to measurable improvements in overall passenger satisfaction. The synthesis of results demonstrates that structured quality management approaches such as Six Sigma can effectively enhance public transportation service quality by providing systematic solutions to operational problems. In conclusion, this research highlights the practical benefits of Six Sigma in improving service performance and reducing passenger complaints, offering valuable insights for policymakers and transportation operators seeking to strengthen the quality and sustainability of public transit systems.
