Identification of Pollutant Sources on PM10: Case Study in West Surabaya

The emission of motor vehicles can cause air pollution, the industry, and household activities and is currently a severe problem. Surabaya City, especially West Surabaya, is an area that has heavy traffic because it is a warehouse area, directly adjacent to Gresik Regency, which is an industrial area and other activities such as garbage Final processing place and port. Therefore, a study needed to monitor the quality of the PM pollutants in West Surabaya and further estimates are the source location of the pollutants. The results of this study can complement previous research and can be used to make policies in air pollution control in Surabaya city. Sampling for fine and coarse particles using Gent Stacked Filter Unit (Gent SFU) every six days between November-December and meteorological data obtained using Kestrel 5500 Weather Meter. The concentration of PM₁₀ was analyzed using the gravimetric method while estimating the pollutant source location using the Conditional Probability Function (CPF). The average concentration of PM₁₀ at the time of research of 32.24 μg/m³. The estimated source location of pollutant for PM₁₀ is from north, northeast, east, south, and southwest and the potential source of pollutant is possible from industrial activities, traffic, warehousing activities, and natural sources such as dirt dust.
