INFLUENCE OF SO2 AND NH3 GAS LEVELS ON PUBLIC HEALTH AROUND BENOWO FINAL DISPOSAL SITE, SURABAYA CITY

Abstract

The pile of organic and inorganic waste on Benowo Final Disposal Site (TPA) in Surabaya City reaches 1,600
– 1,700 tons/day undergoing a process of degradation or decomposition of solid waste, causing unpleasant
odors and toxic gases. Some of the gases that arise are Methane (CH4), Sulfur Dioxide (SO2), Ammonia (NH3),
and Hydrogen Sulfide (H2S). The presence of these gases can cause disturbances to public health. The purpose
of this study is a measure, identify and determine the effect of gas levels of SO2 and NH3 on public health
around the Benowo Final Disposal Site, Surabaya City. This type of the research is descriptive analytic with a
cross sectional approach. This study used primary data collection methods in the form of measurements and
interviews of respondents using proportional random sampling. Data analysis by comparing based on East
Java Governor Regulation No. 10 of 2009 about Ambient Air Quality Standards. The averages result of this
research gas levels of Sulfur Dioxide (SO2) and Ammonia (NH3) at points 1,2 and 3 were 98.95 g/Nm3
respectively; 186.29 g/Nm3
; and 39.87 g/Nm3
and also the averages of NH3 gas at points 1,2 and 3 is 23.92
g/Nm3
; 60.44 g/Nm3
; and 24.21 g/Nm3
. From 25 respondents who live around the Benowo Final Disposal
Site do not feeling health complaints due to the gas that arises, but other factors. The sum up of this study is
the levels of Sulfur Dioxide (SO2) and Ammonia (NH3) gas has qualified from the requirements set by the East
Java Governor Regulation No. 10 of 2009. The physical factors of the air that affect the presence of pollution
are in accordance with the direction and speed of the wind, humidity also has the qualified from the
requirements and the temperature hasn’t qualified from the requirements of SNI T-14-1993-03. Instance and
public has gave some information about result of the research for prevention.
