Abstract

Air pollution is a phenomenon that is often discussed, especially regarding air quality in urban areas. This has become a major contributor to health problems and environmental issues in Asian countries, such as Indonesia, especially Riau Province. The event of forest fires is one of the many events that occurred in Indonesia, especially Riau Province which harmed the population of Indonesia and neighboring countries. The phenomenon of forest forestry generally occurs due to a shift in the season towards drought and can occur in areas prone to forest fires. Therefore, it is necessary to know the model of air pollution distribution by Particulate Matter (PM10) in Pekanbaru City. This study aims to obtain the distribution model for daily air pollution PM10 in Pekanbaru City from 2014 to February 2015. Data were taken from three stations i.e. Sukajadi Station, Tampan Station, and Kulim Station. Four distributions will be tested i.e. Log Pearson III distribution, Gumbel distribution, Generalized Pareto Distribution, and Generalized Extreme Value (GEV) distribution. We test the goodness of fit from these distribution using the Kolmogorov-Smirnov and the Anderson-Darling tests. The result shows that the Generalized Extreme Value (GEV) distribution model was better than the Log Pearson III, Gumbel and Generalized Pareto distribution models for modeling city air pollution data Pekanbaru with three stations namely Sukajadi, Tampan, and Kulim. Keywords: Anderson-Darling; Generalized Extreme Value (GEV); Kolmogorov-Smirnov.
