Geothermal industry is a producer of natural gas including hydrogen sulfide gas (H 2 S) which is very dangerous to humans. This thesis will analyze the hazard risk perceptions of hydrogen sulfide gas (H 2 S) to local workers in the geothermal field of PT. XYZ in 2020. Risk perception is a subjective assessment of the following things, such as the likely types of an accident, the potential hazards that will occur, and how much a person is concerned about the consequences. This study uses a psychometric paradigm which is the best illustration to determine a person's risk perception where this approach can analyze risks by giving good and clear answers from each dimension, including the volunteerism dimension to risk, the dimension of understanding risk, the dimension of controlling risk, the dimension of knowledge towards risk as well as the newness dimension of risk. This study uses a cross-sectional design with a descriptive analysis method. Data obtained through a questionnaire with 90 respondents local workers who then analyzed using the univariate and bivariate analysis to determine the relationship between the dependent variable and the independent variable with a confidence level (CL) of 95%. The results of the analysis show that the description of the risk perception of Hydrogen Sulfide (H 2 S) gas for local workers in the geothermal field of PT. XYZ in 2020 is voluntary toward risk, have a good understanding and able to control of risk while does not have good knowledge especially about the science of hydrogen sulfide gas (H 2 S) and assume the risk of exposure to hydrogen sulfide gas (H 2 S) is an old risk. It is recommended for PT. XYZ to make promotive efforts such as more planned training of hydrogen sulfide gas (H 2 S), maximizing safety induction related to the hazard of hydrogen sulfide gas (H 2 S), maximizing toolbox meeting forums, weekly safety meetings and other meetings to increase workers' awareness regarding hazards Hydrogen Sulfide gas (H 2 S), makes an in-depth analysis of worker observations related to unsafe behavior and also increase the industrial hygiene programs.
Traffic accident caused 1,25 million death for every years and projected to be the third world burden disease at 2030. Aim of this study is to analyzing factors and interaction of each factor related to land transportation safety in PT. XYZ. This study is qualitative research with descriptive analitic design. This study used Haddon Matrix to show driver factor, vehichle factor, physical and social environment factor from each accident's phase.
The chemical manufacturing industry is one of the industrial sectors with high hazard potential and complex work processes, requiring the implementation of a strong occupational safety system. One critical aspect that must be explored in depth is the level of safety culture maturity within a company. This study aims to analyze the maturity level of safety culture at PT. XYZ and identify the differences in perception and engagement among employees. The assessment was conducted using a questionnaire instrument consisting of various safety culture dimensions and elements, supported by data from interviews, focus group discussions, and document reviews. Based on the analysis results, the overall safety culture maturity level at PT. XYZ was found to be at level 3 or Calculative. This indicates that while the company has a structured and well-documented safety management system, safety values have not yet been fully internalized into daily work behaviors. In addition, the study found significant differences in perceptions across job levels and departments, where workers in operational roles had limited involvement in safety evaluation and organizational learning. Areas that require improvement include safety communication effectiveness, employee participation in incident analysis, and consistency in follow-up actions from findings and risk evaluations.
Hasil penelitian menunjukkan bahwa populasi pekerja bahan kimia di PT. XYZ berisiko terhadap pajanan Benzena nonkarsinogenik (RQ = 1,7442) dan karsinogenik (ECR = 1,76 x 10-4) pada durasi pajanan lifetime. Diketahui hubungan yang bermakna antara pajanan Benzena terhadap normalitas kadar hemoglobin (p = 0,015) dan eritrosit (p = 0,000). Risiko ketidaknormalan kadar hemoglobin dan eritrosit berturut-turut pada populasi terpajan adalah 6,92 kali (95% CI:1,28?37,29) dan 21,53 kali (95% CI:4,46?103,90) dibandingkan populasi tidak terpajan. Selain itu juga diketahui hubungan yang signifikan antara kenaikan jumlah asupan Benzena terhadap penurunan kadar haemoglobin (rs = -0,433; p = 0,044) dan eritrosit (rs = -0,474; p = 0,026).
Disimpulkan bahwa risiko kesehatan nonkarsinogenik dan karsinogenik akibat pajanan Benzena pada populasi pekerja bahan kimia di perusahaan minyak dan gas PT. XYZ akan terjadi pada durasi pajanan lifetime. Terdapat hubungan antara pajanan Benzena dengan ketidaknormalan hemoglobin dan eritrosit.
Chemical contractor worker at the oil and gas company PT. XYZ is a population at risk to Benzene exposure due to its activities and work environment condition that possibly exposed by Benzene vapour. This research is aimed to estimate noncarsinogenic and carsinogenic risk level, complemented with blood counts abnormality analysisdue to Benzene exposure, then determining risk management shall be done. The research is cross sectional study was done to all chemical contractor worker at PT. XYZ, consist of 22 person, and additional 22 person as a control was selected from employee of PT. XYZ working at the same location. The research yield that chemical worker population at PT. XYZ is at risk to the noncarsinogenic (RQ = 1.7442) and carsinogenic (ECR = 1.76 x 10-4) Benzene exposure at the lifetime exposure duration.
Its known that there is a correlation between Benzene exposure with normality of haemoglobin (p = 0.015) and erythrocytes (p = 0.000). The risk of abnormality haemoglobin and erythrocytes counts is 6.92 times (95% CI:1.28?37.29) dan 21.53 times (95% CI:4.46?103.90) respectively compare to the non exposed population. In addition, its identified that there is a significant correlation between increased Benzene intake to the haemoglobin (rs = -0.433; p = 0.044) and erythrocytes (rs = -0.474; p = 0.026) counts reduction.
In summary noncarcinogenic and carcinogenic health risk due to Benzene exposure in the population of chemical worker at the oil and gas company PT. XYZ will occure at the lifetime exposure duration. There is a correlation between Benzene exposure with abnormality of haemoglobin and erythrocytes.
Metabolic syndrome is a cluster of some risk factors such as high level of glucose and triglyceride, low level of High Density Lipid (HDL), central obesity, and hypertension. Someone who suffers from metabolic syndrome has higher risk to get chronic disease like cardiovascular disease and diabetes melitus type 2 in the future. As per Medical Check Up result of Oil and Gas Company X workers in 2014, found that dyslipidemia up to 69,4%, obesity 14,8%, overweight 33,17%, diabetes 8,7%. Furthermore, based on observation, office workers of Oil and Gas Company X tend to have sedentary life style since they spent most of their time at office to sit for doing some administrative task and often consume high fat food. Thus, the objective of this study was to analyze the risk factors that associate with metabolik syndrome on Head Office Workers of Oil and Gas Company X using cross sectional design study. The result of this study foud that prevalence of metabolik syndrome on Head Office Workers of Oil and Gas Company X is 25%. The independent variables that were significant with metabolic syndrome were animal protein diet (p value = 0.016), fat diet (p value = 0.037), body mass index (p value= 0,001), physical activity (p value = 0.010), and sedentary lifestyle (p value = 0.030) and smoking (p value= 0,037). Therefore, it is necessary to create strategy in order to provide knowledge and information regarding a balanced diet and increase the willingness of workers to do sufficient and regular physical activity and stop smoking to maintain ideal body weight, having a healthy life style and prevent chronic disase caused by metabolik syndrome
