Perusahaan Pertambangan Minyak dan Gas Bumi Negara (Pertamina) is a stateowned company engaged in the oil business. The products produced by this company <br /> <br /> <br /> include paraxylene, LPG, rafinat, heavy aromatics, and benzene. Some chemical compounds that are often detected at the refinery include H2S, NH3, Methyl Ethyl Ketone (MEK), chlorine, mercury, and Benzene Toluene Xylene (BTX). Acute effect caused by BTX exposure that usually happens to human is affected central nervous system (CNS). The symptoms are nausea, vomiting, dizziness, and headache. If human get exposed with high concentration, then they will experience shaking, limp, blood pressure disruption, headache, instant dizziness, vertigo, vomiting, dehydration, death. Chronic effect from BTX exposure can harm certain organ system. This research was conducted to 40 workers who were considered to be <br /> <br /> <br /> exposed by BTX. Primary data that was taken included the highest BTX compound dosage inhaled by workers, urine sample, physical parameters, questionnaire, and interview to workers. Secondary data that was used was environmental monitoring data from PT. Pertamina RU IV Cilacap. Sampling procedure and analysis for breathing zone refered to NIOSH 1501 (Hydrocarbons, Aromatic). Method that was used to analyze urine sample refered to NIOSH 8301. Inhalation exposured to workers were still below the threshold that was set by the government. The highest benzene intake in KPC Unit was 0.1515 ppm, in Laboratory was 0.2850 ppm, and in Administration was 0.0230 ppm. The highest CDI value in workers was found in the Laboratory with the value of 0.0187 mg/kg.day. There was correlation between CDI and phenol concentration in workers. There were 15 workers who had HI>1, that means the benzene dosage exposure to workers potential to harm workers' health.
