ANALISIS SEBARAN PENCEMARAN UDARA MENGGUNAKAN MODEL DISPERSI GAUSS DAN PEMETAAN ArCGIS 10
Abstract: Bukit Semarang Baru
in Subdistrict Mijen, Semarang Municipality is a large-scale residential
development in which the function of employment, shopping, education, and
recreation. Development of the area lead to an increase in emissions from
transport and industrial activity. Motor vehicle emissions and industrial
stacks effect on the concentration of pollutants in the ambient air in the
surrounding area. This studyaims to determine theair qualityconditions,
patterns andmodelsof airpollutantdistributioninthe study area. The research was
carried out with sampling of ambient air in 15 sampling points in the study
area. The sampling carried out in the morning, afternoon, evening, andnight.
Parameters measured were NO2, SO2, CO, and dust. The results of analysis air
qualityare known from air pollution standard index and mapped ArcGIS10. The
distribution pattern of air pollutants mapped using Surfer10. In addition the
measurements, also carried out calculations according to Gaussian Dispersion
Model of line sources and point sources. Line sources derived from
transportation conditions, while point sources derived from industrial stacks.
The highest concentration of NO2in the Road Ngaliyan-Bojais79.770μg/Nm3, air
pollution standard index value obtained include in good category. The highest
concentration of SO2 at Main Gate is91.424μg/Nm3, air pollution standard index
value obtained is 52 include medium category. The highest CO concentration
obtained at Graha Taman Bunga and Main Gate is 6.866μg/Nm3, air pollution
standard index value obtained is 69 include medium category. The highest
concentration of dust in Sport club for 363.444μg/Nm3, air pollution standard
index value obtained is 190 include unhealthy category.
