KONSENTRASI PARTICULATE MATTER DAN FAKTOR YANG MEMPENGARUHI KEADAAN UDARA DI KOTA MADYA PEKANBARU MENGGUNAKAN AMBIENT DUST ANALYZER

Abstract

Research on the effects of solar intensity, temperature and air humidity to the particulate matter concentration (PM10) has been done by using data interpretation method. Measurements of PM10 concentration were performed by using an ambient dust analyzer FH62-1 series at three monitoring stations in Pekanbaru, namely Kulim Station, Sukajadi Station and Tampan Station. The observed data is daily data from 2011 to 2012, which were processed and analyzed to be monthly average data. Results of data analysis showed that the average PM10 concentration in 2011 was 44.10±17.56 μg/m3, the maximum PM10 concentration were 71.33 μg/m3 in November 2011, while the minimum PM10 concentration occurred in August 2011 at 16.68 μg/m3. The average PM10 concentration in 2012 was 32.54±16.55 μg/m3, with the maximum value reached in November 2012 at 60.50 μg/m3, and the minimum value was 14.32 μg/m3 which occurred in June 2012. PM10 concentration is low when the sunlight intensity and air temperature reach the maximum value, while the value of air humidity is the lowest. PM10 concentration is high when the sunlight intensity and air temperature are low, while air humidity has high value. The trend of PM10 concentrations in atmosphere Pekanbaru 2011 and 2012 is decreased, both for maximum and minimum values. PM10 concentrations were categorized as medium, according to the standard index of air pollution, which is issued by Indonesian Ministry of Environment.
