THE EFFECT OF DISTANCE OF BENOWO WASTE FINAL DISPOSAL (TPA) SURABAYA CITY ON H2S AND NH3 LEVELS IN THE SETTLEMENT ENVIRONMENT

Abstract

Hydrogen Sulfide and Ammonia gas is one of the gases that can cause a source of air pollution that can cause
respiratory tract health problems. This study aims to determine the relationship between distance and levels
of hydrogen sulfide and ammonia in the residential environment. This research is included in analytical
research with approach cross sectional. This study used primary data collection including measurements of
levels of H2S, NH3, and meteorological factors. Sampling of H2S and NH3 was carried out at 3 points, at point
1: a radius of 100 meters, point 2: a radius of 500 meters and point 3: a radius of 1000 meters. The data were
analyzed using the Correlation Test Spearman. The results showed that the average temperature of point I was
31.1oC, point II was 32oC, and point III was 32.1oC. Humidity at point I was 69.3%, point II was 68.3%, and
point III was 69%. The wind speed is around 0.7 m/s. Levels of H2S point I 0,041 ppm, point II 0.04 ppm and
point III 0.04 ppm. And the levels of NH3 point I 1,813 ppm, point II 1,776 ppm and point III 1,882 ppm. The
conclusion of this study is that there is an effect between distance and levels of H2S in residential areas and
there is no effect between distance and levels of NH3 in residential areas. So it is advisable to monitor air
quality regularly and plant lots of plants that can absorb pollutant gases around the Benowo waste landfill.
