Hydrogen Sulfide Exsposure Coverage for Residents' Health Risk at Sukawinata Landfill

This study aims was to assess environmental health risk of hydrogen sulfide gases exposure for residents living around Sukawinatan Landfill. Methods: This study was descriptive research and used quantitative analysis method. The approach used was Environmental Health and Risk Assessment. Sample in this research was 100 respondents who were divided two radiuses, 300 meters and 600 meters away from the landfills, 50 respondents for each radius. Purposive Sampling was conducted to select respondents. Air sampling was conducted to assess hydrogen sulfide concentration around landfill. Data was collected through interview using questionnaires, weighing weight and assessment of hydrogen sulfide concentration used impinger. Data analysis was conducted using univariate and risk analysis. Result: The study found that the average of hydrogen sulfide concentration in radius 300 and 600 meters were 0, 0017 mg/m3 and 0, 0023 mg/m3 which were not exceed the threshold based on State Minister of The Environment decision Number 50 in 1996. Then, we still found that the residents remained at risk with RQ ≥ 1. The risk analysis resulted that there were 38% residents in 300 meters and 30% residents in 600 meter radius had RQ ≥ 1. Discussion and Conclusion: Though, the concentration of Hydrogen sulfide was still below the threshold but the residents living around Sukawinata landfill would be at risk to be exposed by Hydrogen sulfide which is dangerous for their health. Relocation of sukawinata landfill should be conducted since it is not eligible for landfill area anymore.
