Abstract

Traditional yellow tofu production involves various manual activities that may expose workers to occupational hazards if safety aspects are not properly managed. This study aims to identify occupational hazards and determine appropriate control measures in traditional yellow tofu production using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method. The research was conducted at FMY Tofu Factory in Bandung, Indonesia, through direct observation, worker interviews, and documentation of production activities. Hazard identification was carried out at each production stage, including washing, soaking, grinding, boiling, filtering, coagulation, molding, re-boiling, and cutting. The identified hazards were classified into physical, ergonomic, mechanical, electrical, chemical, biological, and environmental hazards. Risk assessment was performed using likelihood and severity parameters to determine risk levels. The results identified 27 potential hazards with risk levels ranging from low to very high. Very high risks were mainly found in the grinding, boiling, and cutting stages due to exposure to rotating machinery, damaged electrical equipment, high temperatures, and sharp cutting tools. High risks were associated with slippery floors, repetitive manual handling, and awkward working postures. Recommended control measures include installing machine guards, improving ventilation and drainage systems, implementing ergonomic workstations, conducting routine electrical inspections, and providing appropriate personal protective equipment such as heat-resistant and cut-resistant gloves. The implementation of HIRADC provides a systematic approach to improving occupational safety and health conditions and reducing workplace accidents in traditional yellow tofu production.

Abstract

Occupational Safety and Health (OSH) is an essential aspect of industrial activities that contributes to the creation of a safe, healthy, and productive work environment. The high risk of workplace accidents in production processes requires companies to implement effective OSH programs to minimize potential hazards that may cause losses to both workers and the company. This study aims to analyze the implementation of Occupational Safety and Health (OSH) as an effort to prevent workplace accidents in the production process at PT XX. The research employed a descriptive qualitative method, with data collected through field observations, interviews, and document reviews. The results indicate that PT XX has implemented various OSH programs, including the use of personal protective equipment (PPE), occupational safety training, installation of safety signs, and routine inspections of production areas and work equipment. However, several challenges were still identified, such as suboptimal worker compliance with PPE usage and limited awareness of potential hazards in the workplace. The consistent implementation of OSH practices has been proven to reduce the risk of workplace accidents and support the continuity of production activities. Therefore, continuous improvement in supervision, employee guidance, and the strengthening of a safety culture are necessary to enhance the effectiveness of OSH implementation within the company.

Abstract

The recycled paper manufacturing industry involves various production stages that may expose workers to occupational hazards. This study aims to identify potential hazards, assess risk levels, and determine appropriate control measures in the production of recycled paper (Samson kraft) using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method. Data were collected through direct observation, interviews with production workers and laboratory personnel, and documentation of production activities. Hazard identification was conducted in all production stages, including raw material storage and pressing, hydropulping, stock preparation, paper machine operations (wire part, press part, and dryer part), calendering, pope reel operations, and wastewater treatment. The results identified 24 potential hazards categorized as physical, mechanical, chemical, ergonomic, environmental, electrical, and biological hazards. Risk assessment indicated that Very High risks were concentrated in hydropulping, press part, dryer part, and calendering operations due to rotating machinery entrapment and exposure to high-temperature steam. High risks were associated with slippery floors, noise exposure, chemical handling, and material handling activities, while medium risks were mainly related to ergonomic strain and low-level chemical exposure. Evaluation of existing controls showed that risk mitigation measures were primarily based on administrative controls and personal protective equipment (PPE), whereas engineering controls remained limited in several critical areas. Residual risk assessment demonstrated that risk levels decreased after implementing proposed controls; however, several hazards remained at medium risk levels. Therefore, strengthening engineering controls, safety training, and safety culture is necessary to improve occupational safety performance in recycled paper manufacturing facilities.
