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.
Kelelahan kerja (fatigue) merupakan sebuah kondisi dimana seorang pekerja/tenaga kerja tidak bekerja secara maksimal dan mengalami penurunan produktivitas. International Labour Organization (ILO) (2016) mengatakan bahwa sebanyak 32% pekerja/tenaga kerja mengalami kasus kelelahan kerja. Selain itu, 27% pekerja/tenaga kerja mengalami kasus kelelahan kerja berat dan 18,3% pekerja/tenaga kerja mengalami kasus kelelahan kerja sedang. Kelelahan kerja juga akan dapat menyebabkan penurunan produktivitas kerja, peningkatan risiko pekerja/tenaga kerja melakukan kesalahan, dan peningkatan risiko terjadinya kecelakaan kerja. Desain penelitian pada penelitian ini adalah cross sectional. Tujuan penelitian ini adalah untuk menganalisis faktor risiko kelelahan kerja pada pekerja/tenaga kerja pengelasan di industri minyak dan gas bumi dengan pendekatan kuantitatif. Sampel pada penelitian ini berjumlah 97 pekerja/tenaga kerja welder di PT XYZ. Metode pengambilan data dengan melakukan pengisian kuesioner kepada responden dan melakukan pengukuran menggunakan alat oxymeter, lux meter, sound level meter, dan thermometer dan humidity meter. Data akan diolah secara deskriptif dan inferensial untuk melihat gambaran dan hubungan dari setiap variabel. Variabel independen pada penelitian ini adalah faktor individu (usia, masa kerja, kebiasaan merokok, dan waktu istirahat), faktor pekerja/tenaga kerjaan (beban kerja fisik, beban kerja mental, dan durasi kerja harian), dan faktor lingkungan kerja (kebisingan, pencahayaan, dan suhu). Hasil penelitian menunjukan bahwa terdapat hubungan yang signifikan antara kebiasaan merokok (OR=3.100 (1.253 – 7.672)), waktu istirahat (OR=5.913 (2.314–15.110)) , beban kerja fisik (OR=3.529 (1.509 - 8.256)), beban kerja mental (OR=2.658 (1.144–6.180)), kebisingan (OR=4.370 (1.844 – 10.354)), dan suhu (OR=4.083 (1.386-12.031)) dengan kejadian kelelahan kerja pada welder di PT. XYZ Sedangkan variabel usia, masa kerja, durasi kerja harian, dan pencahayaan tidak menunjukan adanya hubungan dengan kejadian kelelahan kerja pada welder di PT.XYZ.

Work fatigue is a condition where a worker does not work optimally and experiences decreased productivity. The International Labor Organization (ILO) (2016) said that as many as 32% of workers experience work fatigue. In addition, 27% of workers experience severe work fatigue and 18.3% of workers experience moderate work fatigue. Work fatigue can also cause decreased work productivity, increased risk of workers making mistakes, and increased risk of work accidents. The research design in this study was cross-sectional. The purpose of this study was to analyze the risk factors for work fatigue in welding workers in the oil and gas industry using a quantitative approach. The sample in this study was 97 welder workers at PT XYZ. The data collection method was by filling out questionnaires to respondents and taking measurements using an oxymeter, lux meter, sound level meter, and thermometer & humidity meter. The data will be processed descriptively and inferentially to see the picture and relationship of each variable. The independent variables in this study were individual factors (age, length of service, smoking habits, and rest time), work factors (physical workload, mental workload, and daily work duration), and work environment factors (noise, lighting, and temperature). The results showed that there was a significant relationship between smoking habits (OR=3.100 (1.253 – 7.672)), rest time (OR=5.913 (2.314–15.110)), physical workload (OR=3.529 (1.509 - 8.256)), mental workload (OR=2.658 (1.144–6.180)), noise (OR=4.370 (1.844 – 10.354)), and temperature (OR=4.083 (1.386-12.031)) with the occurrence of work fatigue in welders at PT. XYZ Meanwhile, the variables of age, length of service, daily work duration, and lighting did not show any relationship with the occurrence of work fatigue in welders at PT.XYZ.

This study is about the relationship between personal noise dose exposure with Subjective complaints (Non Auditory) On Workers At Utilities Area 05 In A Leading Oil and Gas Company in 2015. Personal noise exposure dose was measured by using a Noise Dosimeter, while the data of respondents and subjective complaints (non audiotory) was obtained by a questionnaire. Method which is used in this research is quantitative observation and data collection. The results showed there is no relationship between the personal noise exposure dose with subjective complaints (non audiotory).
Keywords: personal noise dose exposure, Subjective complaints (Non Auditory).
