One of the main purpose of accident investigation is to create recommendations for corrective actions in order to prevent the recurrent accident in the future. Some reccurent accidents at PT.X indicating that the previous accident investigations have not done effectively. One of the main factors in accident investigation is the quality of investigators, because investigators conduct the whole steps of accident investigation. Based on an early interview with some of the investigators, they said that they‟ve never been trained about accident investigation. Thus, this qualitative study aims to assess the quality of accident investigators at PT.X. The aspects of quality that will be assessed in this study are competency, consistency, and the ability of investigators to be open minded. The method used in this study is descriptive qualitative with in-depth interviews, observations, and secondary data. The result showed that the overall quality of accident investigators at PT.X is categorized not good, in which the competency aspect is poor, consistency aspect is good, and the ability of investigators to be open minded aspect is good enough.

The focus of this research is to analyze all occupational accidents of lifting activities on land rig operations in PT ‘X’ using the Human Factor Analysis and Classifications System (HFACS) method in 2014 - 2018. The type of research methodology is qualitative research with a descriptive design. The final result shows that the unsafe act layer is the most ineffective layer that contributing to almost all occupational accident cases which is 45 of 49 total cases of occupational accidents. Error is the sub-layer of unsafe act which has the highest number of contributions to occupational accident cases with total 39 cases. On the other side, the organizational influences layer is the second layer that has high contribution to accident which is 26 of 49 total cases of occupational accidents. The organizational process is the sub-layer of organizational influences which contributing to 23 cases of occupational accident. The third layer which has contribution to accident is unsafe supervision. The unsafe supervision has contribution to accident which is 16 of 49 total cases of occupational accidents. Inadequate supervision and planned inappropriate operation are the sub-layer of inadequate supervision which contribute to the accident cases for 10 cases equally. The layer of preconditions for unsafe actions is the effective layer which has contribution to occupational accident cases which is 8 of 49 total cases of occupational accidents. Personnel factor is the sub-layer of preconditions for unsafe actions which contribute to 7 cases of occupational accidents. According to the result, researcher recommend that corrective action must be taken at each layer of HFACS as the safety protection system, both latent failures and active failures with the emphasis on improvement, which start from the organizational influences layer, followed by the unsafe supervisions layer, and then unsafe actions layer, while the improvement on the layer of precondition for unsafe actions becomes the last improvement. Improvement to organizational influences layer, unsafe act layer, and unsafe supervisions layer will have a positive influence on the layer of precondition for unsafe actions.

This study discusses about the risk analysis of occupational health and safety in the working process Die Casting Plan 3 PT. X in May-June 2016. This study used a descriptive research design with AS / NZS ISO 31000: 2009 as standard for the risk assessment process of occupational health and safety. The method used in the risk assessment is a semi-quantitative mathematical formula W. T Fine. Risk identification method in this study adopted by Job Hazard Analysis (JHA). The purpose of this study was to determine the risk level of occupational health and safety in the working process Die Casting. The results showed that found as many as 58 risks in the working process Die Casting. where the initial risk assessment (basic risk) as much as 48.27% of risk with a very high level, 24.14% of risk with substantial risk level, 18.97% of risk with risk priority level 3, and 8.62% risk risk level priority 1. Then these risks reassessed taking into account the existing controls (existing risk) to 46.55% of risk with risk priority level 3, 24.13% of risk with substantial risk level, 13.80% risk risk priority level 1, 8.62% of risk with a very high level of risk, and 6.90% to the level of risk acceptable risk. While on the fourth working process Die Casting, there are 5 biggest risk to the level of risk that is not acceptable, is very high, priority 1 and substantial. Therefore, given advice on the control of the 5 biggest risks of each process that is engineering controls, administrative controls or personal protective control.
