In 2019, Company X made changes to the drilling fluid used for drilling activity. Benzene is a carcinogenic compound that can be found in drilling fluid and can cause acute and/or chronic disease. This study will analyze the impact of changing drilling fluids by measuring the concentration of benzene in the air from the use of the old drilling fluid and the new drilling fluid, knowing the concentration of benzene in the air in the work area with the new drilling fluid, knowing the benzene exposure of workers with the new drilling fluid, and knowing effectiveness of the LEV used in several locations. From this study, it was found that there was a significant difference in the measurement of the concentration of benzene in the air caused by the change of drilling fluid in the flowline (p = 0.035) and shale shaker (0.004) and not significant in the active pit (p = 0.223). With the use of new drilling fluids, several locations have concentrations with an average concentration of benzene in the breathing zone that exceeds the Threshold Limit Value-Time Weighted Average (TLV-TWA), namely in the active pit (1.64 ppm), reserve pit (1.11 ppm), flowline below the rig floor (0.34 ppm) and possum belly (0.31 ppm). Workers working in the drilling fluid circulation area in this study were exposed to an average concentration of benzene with concentrations below the TLV-TWA and had benzene metabolites (SPMA) below the IPB value. In this study it was found that LEV was not effective for reducing benzene concentrations in areas with open reservoir types (flowline, p = 0.346 and possum belly, p = 0.346) and effective for closed reservoir types (Active pit, p < 0.001).
Hasil penelitian menunjukkan karakteristik sikap (personality) yang dimiliki oleh pimpinan kurang optimal pada karakteristik ketahanan emosi, bersikap terbuka, berorientasi pada pembelajaran dan sikap berhati-hati. Karakteristik gaya kepemimpinan transformasional pada pimpinan kurang optimal pada karakteristik ikut terlibat. Karakteristik praktik terbaik yang dimiliki oleh para pimpinan masih kurang optimal pada karakteristik tanggung jawab. Untuk meningkatkan karakteristik safety leadership, maka perlu adanya pelatihan ulang mengenai safety leadership bagi para pimpinan untuk menyegarkan kembali pemahaman yang kurang optimal tentang safety leadership, mengkaji ulang job description yang ada dan mengembangkan Job description safety leadership yang lebih terukur dan penilaian atau audit safety leadership di departemen drilling PT. X.
Geothermal, oil and gas drilling are known as projects with high work risks and require high costs. Several studies strongly indicate that safety leadership management influences the success of behavioral safety processes. The leadership role in the Drilling department in working on drilling projects will be one of the benchmarks of success related to positive safety outcomes. This study is a qualitative method approach to analyze three factors that influence safety leadership, namely personality, transformational leadership style, and best practices in the position of Head and Assistant Head. Data was collected in April-July 2020 in the Drilling department of PT. X through in-depth interviews, document review and observation.
The results showed the characteristics of personality possessed by the leader is less than optimal on the characteristics of emotional resilience, extroversion, learning orientation and conscientiousness. The characteristics of transformational leadership styles are less than optimal on the characteristics of Engaging. Characteristics of best practices are still not optimal in terms of accountability characteristics. To improve the characteristics of safety leadership, it is necessary to have retraining on safety leadership for leaders to refresh the suboptimal understanding of safety leadership, review existing job descriptions and develop a more measured Job description of safety leadership and an assessment or audit of safety leadership in drilling department of PT. X.
Workplace accidents resulting in Lost Time Injury (LTI) pose a serious challenge in maintaining occupational safety and operational efficiency, particularly in the logistics sector, which is known for its high level of risk. This study aims to analyze the causes of LTI-category workplace accidents in Group Company X in 2024 from the perspective of human factors using the Human Factors Analysis and Classification System (HFACS), which is based on the Swiss Cheese Model theory. A descriptive-analytic method with a qualitative approach was employed through the review of accident investigation reports and interviews with key persons. The findings reveal that the most significant contributing factors to LTI cases include, under latent conditions: organizational culture, planned inappropriate operations, physical environment, and tools/technology; while under active failures, the dominant factor is skill-based errors. Improvements in work systems, both at the organizational and individual levels, are necessary to create a safer and more sustainable work environment.
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 aims to determine the hazards and risks analysis that exist in the maintenance activities of the ride X. This research was conducted with semi-quantitative design and using AS/NZS: 4360. Work process obtained from SOPs and in-depth interviews. The criteria of level analysis; exposure, possibilities, consequences, and risk level by W.T. Fine. The maintenance activities analyzed are daily and weekly (greasing). The results elucidate that most hazards incurred by workers for daily maintenance were physical hazards (altitude and electrical) at work process of inspection of the neple and tentacle hydraulic oil. Meanwhile, as for greasing activity, physical (altitude) is the most dangerous hazard at the work process to the location of grease replacement. In addition, controls that have been done by the company, among others, by dividing the work shift and providing the vehicle such as golf car and PPE in the form of; gloves, safety shoes, body harness, helmets, and googles.
