State electricity company is an Indonesian government-owned corporation with a monopoly on Indonesia's electricity distribution. Sulfur dioxide (SO) pollution is produced by burning fossil fuels with coal and oil-fired power plants. At the combined cycle power plant (CCPP), the state electricity company has the largest role in SO production. In addition, SO can cause respiratory tract dysfunction, decreased lung function, eye irritation, throat irritation, and coughing at certain concentrations. This study aims to assess the magnitude of SO exposure to workers health at CCPP Indralaya unit, Indonesia. The research is a quantitative study using the environmental health risk assessment (EHRA) method. Purposive sampling was used to obtain 32 respondents. The results revealed that the average SO concentration was 0.085 mg/m. The non-carcinogenic intake was 0.0025 mg/kg/day for real-time exposure and 0.0069 mg/kg/day for lifetime exposure. The Risk Quotient (RQ) for real-time exposure obtained is 0.0959, and RQ for lifetime exposure is 0.2668, indicating an RQ = 1. The study concluded that the CCPP Indralaya unit is not at-risk cause non-carcinogenic due to SO exposure. Regardless, precautions must ensure that workers' exposure to SO or other emissions gases produced by CCPP activities does not endanger their health.
国家电力公司是一家印度尼西亚国有公司，垄断了印度尼西亚的电力分配。二氧化硫（SO）污染是由燃煤和燃油发电厂燃烧化石燃料产生的。在联合循环发电厂（CCPP）中，国家电力公司在SO产生方面发挥着最大作用。此外，SO在一定浓度下会导致呼吸道功能障碍、肺功能下降、眼睛刺激、喉咙刺激和咳嗽。本研究旨在评估印度尼西亚Indralaya单位CCPP工人接触SO对健康的影响程度。该研究是一项使用环境健康风险评估（EHRA）方法的定量研究。采用目的抽样法获得32名受访者。结果显示，SO的平均浓度为0.085 mg/m。实时暴露的非致癌摄入量为0.0025 mg/kg/天，终身暴露的非致癌摄入量为0.0069 mg/kg/天。获得的实时暴露风险商（RQ）为0.0959，终身暴露风险商为0.2668，表明RQ = 1。该研究得出结论，Indralaya单位CCPP因SO暴露不存在非致癌风险。尽管如此，仍必须采取预防措施，确保工人接触CCPP活动产生的SO或其他排放气体不会危及他们的健康。
