Abstract

PT. XYZ is a foundry company that has difficulty achieving production targets compared to previous years. This study aims to evaluate the level of productivity using the Objective Matrix (OMAX) method. The highest productivity value in September 2022 with a value of 540. Meanwhile, the lowest productivity value was in October 2022 with a value of 340. The amount of total production compared to the total use of raw materials plays an important role in increasing productivity. In the productivity criteria of effective working hours, the criteria of machine working hours, and production effectiveness show good values. While the criteria for the effectiveness of product defects are not good because they show the lowest value. Based on the analysis of the fault tree analysis (FTA) method, it was found that there were 10 basic events that caused problems from low productivity, namely the presence of inexperienced operators, no assembly marks on the mold, no mold density standards, no schedule for calibration, leaky storage roofs, lack of quality control in the supply of raw materials, no separation between raw materials, Sifting is not clean, lack of regular machine maintenance, and induction furnaces that are not cleaned every production session.

Abstract

Every work environment certainly contains high potential hazards so that prevention and control efforts are needed so that work accidents do not occur. Because the production process uses machines and the work at each station has different risks of work accidents and potential sources of danger, it is necessary to analyze the Potential Hazards and Risks of Work Accidents in the Production Section of PG Madukismo using the Hazard Identification, Risk Assessment and Risk Control (HIRARC) Method. The results showed that in the work activities at PG Madukismo there was 1 work activity with extreme risk category, 34 activities with high risk category, 67 work activities with moderate risk category work activities and 15 work activities with low risk category. The control that can be done is to supervise the use of PPE such as masks, safety shoes, safety gloves, safety glasses, ear plugs, safety harnesses and helmets during the work process. Implementing engineering control by making handrails on stairs that do not have handles and making protective fences and installing toe boards and others. Administrative control is by installing warning signs and safety guards, understanding and carrying out work activities according to the SOP.
