The Hazard and Operability (HAZOP) methodology is a qualitative risk analysis technique commonly used to detect potential work hazards. CV. Suryadi Sentosa, also known as Bapak Suryadi's Home Tempe Industry, is a home-based business that produces tempeh. Almost all of the production procedures are still carried out manually, and occupational accident analysis measures have not been implemented. The factory conditions indicate inadequate lighting and ventilation, as well as relatively slippery floors. It is also observed that the industry workers do not pay much attention to their posture, and they do not use personal protective equipment (PPE). This research was conducted directly at the CV. Suryadi Sentosa Tempe Factory, using interviews and observations of seven workers involved in the production process. The steps taken in this study are compiling the sequence of the production process. By using a Hazard and Operability (HAZOP) worksheet, identify potential risks, conduct risk control analysis, monitor and evaluate, implement improvements, and draw conclusions. The analysis found 9 stages of tempeh production at Mr. Suryadi's facility. Several improvements are needed, including involving several workers to handle soybean processing, creating ventilation to provide good and healthy air circulation for workers, adding lighting as a light source so that workers can perform their tasks comfortably, and using ergonomic chairs and work tables to prevent fatigue and increase factory productivity.

This research aims to analyze the risk factors of occupational accidents and identify effective prevention efforts within the context of Micro, Small, and Medium Enterprises (MSMEs), specifically at Inkside Sablon. This qualitative study, employing a case study approach, utilized in-depth interviews, participant observation, and documentary analysis for data collection. The findings indicate that occupational accident risk factors at Inkside Sablon are influenced by several aspects, including human factors such as lack of safety awareness and fatigue, environmental factors like inadequate ventilation and suboptimal lighting, and equipment factors such as non-ergonomic tools and insufficient maintenance. The prevention efforts implemented by Inkside Sablon are still partial and not well-structured, thus requiring the integration of more comprehensive safety programs, such as enhanced safety and health (OSH) training, provision of appropriate personal protective equipment (PPE), and improvements in management and supervision systems. It is expected that the implementation of these measures will increase worker awareness and reduce the number of occupational accidents, thereby creating a safer and more productive work environment

This study evaluates the lighting intensity in an automotive parts manufacturing company in East Java, focusing on compliance with SNI 7062:2019 and SNI 7391:2008 standards. This study addresses the critical industrial hygiene-related issue of inadequate lighting experienced by workers, which can lead to health risks such as eyestrain and increased accident rates. The methodology used was quantitative, involving direct observation and measurement using a calibrated lux meter. The data collected was analyzed through the Anticipation, Recognition, Evaluation and Control (AREP) method to assess the existing lighting conditions and their impact on worker safety and comfort. Findings show that current lighting levels do not meet set standards, highlighting the need for improvements in the working environment. Recommendations for improving lighting conditions are provided to ensure compliance with safety regulations and to promote employee well-being. This research emphasizes the importance of proper lighting in manufacturing settings, contributing to the wider discourse on occupational health and safety in the automotive industry.

This project is motivated by the high risk of work accidents in the concrete production process, especially at night when there is poor lighting. Based on observations, there were various significant work incidents, such as injuries from sharp objects and being caught in heavy equipment, which indicate the need for increased risk control. This study aims to design personal protective equipment in the form of an innovative safety helmet using the Job Safety Analysis (JSA) method to improve occupational safety and health (K3) at PT Adhi Persada Beton Batching Plant Kebonarum. The methodology used includes hazard identification, risk analysis, and solution development in the form of designing a safety helmet that is adjusted to the ergonomic needs of workers. This study also includes analysis of work accident data, identification of potential hazards, and evaluation of the effectiveness of existing personal protective equipment. The results of the study indicate that the application of the JSA method can identify risks in a more structured manner, as well as produce recommendations for safety helmet innovations that can improve worker protection against potential hazards.
