Cement Production Company (CPC, a nickname) is a company engaged in the production and distribution of cement. CPC has a long series of production processes, has various potential hazards and impacts the environment, health, and safety. Therefore, research is needed to improve workplace safety. Based on interviews with workers at CPC, the raw mill and kiln areas are areas with a lot of potential hazards. Raw mill and kiln are areas with a sound intensity that exceeds the threshold value of 85dB. In addition, the process in both areas requires high temperatures of up to 1500 °C. This study uses the Hazard Identification, Risk Assessment and Risk Control (HIRARC) approach. This approach aims to identify hazards that may occur in the workplace, provide a risk assessment and classification according to safety or acceptable impacts on the environment and provide suggestions for improvement. Compared to the proposed improvements to get the best alternative with Pugh's method and carried out the work accident cost analysis using the Benefit-Cost Analysis (BCA) method to determine the amount of profit received by the company after being compared with the losses due to work accidents. The expected result of this research is a risk control by proposing the best work accident prevention mechanism based on quality and cost.
