This study was conducted to analyze the causes of occupational accidents and to identify potential hazards in the material cutting process at PT Kanaan Global Indonesia using the Job Safety Analysis (JSA) approach. The high number of occupational accidents, totaling 15 cases during the period of December 2024–May 2025, indicates the existence of gaps in occupational safety control in this area. Data were collected through direct observation, interviews with workers, and the collection of historical data from the Occupational Health and Safety (OHS) unit. Risk analysis was carried out using a risk matrix to determine likelihood and severity values, followed by JSA for each work stage. The results identified 25 potential hazards, consisting of 4 risks in the extreme category, 9 in the high category, 7 in the medium category, and 5 in the low category. High-risk hazards were predominantly found in roll cutting and cutting press machines, which are characterized by mechanical hazards. Control recommendations focus on the implementation of engineering controls such as the installation of guarding systems and safety light curtains, improvements in safe work procedures, and increased discipline in the use of personal protective equipment (PPE). These findings demonstrate that the JSA method provides a comprehensive overview of risk sources and serves as an effective basis for formulating occupational accident control strategies within the company.

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

Occupational Health and Safety (OHS) is a systematic effort aimed at protecting workers from the risks of accidents and work-related diseases. The implementation of OHS integrated with risk management helps identify, evaluate, and control potential hazards effectively in the workplace. This study was conducted at PT. Sarana Sampit Mentaya Utama, Balikpapan Branch, a company engaged in asphalt production. The main objectives of this research were to identify potential hazards, determine appropriate control measures, and evaluate the role of the Job Safety Analysis (JSA) method in supporting OHS. The research method used is JSA, which involves identifying each work step, determining the likelihood and severity of risks, and calculating the risk rating to assess the level of risk. The results showed that there are three potential hazards with a medium-risk category, namely in the activities of raw material mixing, quality control, and asphalt distribution. Additionally, three potential hazards with a low-risk category were found in the processes of raw material weighing, raw material transfer, and pump line valve opening. Recommended control measures to reduce risks include the use of appropriate personal protective equipment (PPE) for each task, improving work facilities and infrastructure, and implementing proper load lifting procedures. The application of JSA has proven effective in raising the company's awareness of potential risks in the workplace. This has led to the implementation of better preventive measures, ultimately contributing to the creation of a safer, healthier, and more productive work environment. Therefore, the integration of OHS with risk management at PT. Sarana Sampit Mentaya Utama plays a significant role in safeguarding the safety and well-being of workers.

This study was conducted to analyze the effect of occupational safety and health (OHS) training, OHS compliance, and leadership style on the workplace accident rate among employees of PT. XYZ. Workplace accidents remain a significant problem in the industrial sector, thus this study seeks to provide a deeper understanding of the factors that can reduce this risk. The research method used was a quantitative survey approach, where primary data were obtained by distributing questionnaires to 40 respondents selected using a non-probability sampling technique with a purposive sampling method. The analysis techniques used in this study were descriptive analysis and multiple linear regression with the help of SPSS software version 25. The use of regression analysis allows researchers to determine the strength and direction of the relationship between independent and dependent variables. The results show that OHS compliance has a significant influence on the workplace accident rate. This confirms that compliance with occupational safety and health procedures can minimize the risk of accidents. Meanwhile, OHS training and leadership style did not show a significant influence on workplace accidents. This finding indicates that training programs and leadership style may not directly reduce workplace accidents unless they are consistently implemented and supported by strong compliance. Thus, OHS compliance is a key factor in creating a safe and productive work environment. This research provides a practical contribution for companies to focus safety management policies more on improving worker compliance with OHS regulations. Furthermore, the results of this study can serve as a reference for further research in different industrial contexts.
