| Summary: | Nickel is a metal that is often processed for daily needs and nickel is also an
abundant metal iron. Nickel is usually processed into materials for coatings,
steelmaking alloys, plating, and stainless steel. In nickel mining activities, sources
of air pollution are generated from several mining activities such as stripping,
nickel ore, use of heavy vehicles, crushing and milling, atmospheric leaching, nickel
drying, and secondary neutralization which can cause a decrease in air quality.
Efforts that can be made to maintain air quality and prevent air pollution are to
predict air concentrations by modeling the spread of pollutants. In this study, the
types of pollutants that will be modeled are TSP, PM2,5, PM10, SO2 and NOx
generated from 3 types of sources, point sources, area sources and line sources. Air
dispersion modeling was carried out using AERMOD software. In operation using
AERMOD, meteorological data is required and processed by AERMET and also
topographic data is processed using AERMAP. The results of pollutant dispersion
modeling will be compared with Government Regulation no. 22 of 2021 and based
on the results of this study, the types of pollutants that pass the quality standard are
NOx and SO2 in 24-hour and 1- year measurements. |
