Abstract:
This research’s aim was to identify the relationship between weather element with PM10
concentration in Banjarbaru both during normal condition and during smoke fog (smog)
condition, to study the condition’s effect afflicts to weather element and PM10 concentration
in ambient air and to determine standard quality concentration PM10’s threshold in ambient air
during smog condition. The data were 10 minute PM10, humidity, and temperature and daily
weather of 2015 that obtained from Banjarbaru Climatology Station meanwhile data of
hotspot’s in South Kalimantan at 2015 was taken from MODIS satellite of Terra Aqua owned
by NOAA. The 10 minutes data has been clustered using K-means method and the daily weather
element relationship with PM10 concentration obtained based on regression analysis. When
normal conditions, only temperature, and duration of irradiance were significantly has
positively correlated with PM10 concentration, air humidity and significant rainfall are
negatively correlated, the remain is not significant in effect, while during smog conditions;
temperature, duration of irradiation, air pressure, average wind velocity, and maximum
significant wind speed are positively correlated, air humidity, and rainfall significantly
negatively correlated. Based on the results of K-means clustering analysis of PM10
concentration, there was higher humidity, higher temperature, and PM10 concentrations were
below the standard quality threshold under normal conditions while in the case of smog
conditions, lower humidity, lower temperature, and PM10 concentrations were above the
quality standard threshold. PM10 concentration during smog condition reaches dangerous
status/above the standard quality threshold before dry season until late dry season at 02.20 is in
the dusk until 12.30 pm
