Both of pollutants have been classified as carcinogenic compound. The ecological risk assessment of drinking water is an effective tool to evaluate drinking water quality to reduce further risk. Fourteen well water samples were collected around the residential area near cement industrial activity and karst mining area. Estimating the ecological risk of well water which consumed daily evaluated based on Hazard Quotient (HQ) ratio. The mean values of Cr(VI) and SiO in well water samples were 0.0017mg/L and 12.94mg/L, respectively. Drinking water in this area are unacceptable. HQ values for SiO at all stations are more than 1 (moderate level). Cr(VI) and SiO are discoverable within well water surrounding the research location. This finding is used as scientific data and references for ecological protection of drinking water in Maros. Cr(VI) and SiO2 are discoverable within well water surrounding the research location. This finding is used as scientific data and references for ecological protection of drinking water in Maros. To identify factors related to the stress levels among pregnant women in Indonesia. The study was used cross sectional design. The participants were 92 pregnant women who worked at a footwear manufacturer at Banten, Indonesia. Half of the participants worked less than 40h per week and the other half worked 40h or more per week. A test instrument to measure stress in pregnant women was developed and conducted in this study. Dependent and independent factors were analyzed by the chi-square test. Our results showed that 59.78% of respondents had their gestational age was more than 31 weeks; 53.00% of workers experienced moderate stress; and as many 53.26% of respondents experienced a high workload. Our conclusion confirmed gestational age, workload, and worki
