Abstract

This study aims to identify and reduce waiting waste in the assembly process of product X through the application of lean manufacturing principles. The methods employed include value stream mapping, cycle time analysis, and the implementation of 5S. Conducted at PT. Z, the results indicate several significant sources of waiting waste, such as additional movements during material disposal and retrieval, waiting for materials during the buffing process, and machine downtime during the welding bracket process. By applying lean tools such as balanced production, single minute exchange of die, and a kanban system. Furthermore, resource utilization improved, and product quality also showed enhancement. The conclusion of this research emphasizes that lean manufacturing is an effective approach to addressing waiting waste issues in the assembly process and enhancing production efficiency.

Abstract

Occupational Health and Safety (OHS) is an important aspect in the automotive manufacturing industry which has high hazard potential, especially in the welding production field. This research aims to identify potential hazards, conduct risk assessments, and determine control measures using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method at the Welding Department of PT Otomotif ZX. The research method used is descriptive quantitative through direct observation and HIRADC data analysis. The results show that out of a total of 5 main work activities, 24 potential hazards were found with risk classifications as follows: 1 extreme risk, 14 high risks, and 9 medium risks. The potential hazards include risks of cuts, burns, hearing impairment, and muscle injuries due to non-ergonomic work postures. Based on the risk assessment results, control recommendations were developed through the five levels of the hierarchy of controls, namely elimination, substitution, engineering controls, administration, and the use of personal protective equipment (PPE). The implementation of the HIRADC method has been proven effective in helping companies identify risks and determine appropriate preventive actions to create a safer and more productive work environment.
