| Summary: | Indonesia is a country which has a very extensive peatlands. From the 37.80 million ha of
peatland area in the world, 20.6 million ha is in Indonesia. From the total peatland area
of Indonesia, 33.9% were in the Kalimantan.. Kalimantan peatland distributed on the
west coastal area, including Kubu Raya district. Indonesian society still doing land
clearing by slash and burn. Every year, approximately 1.5 to 2.2 million ha of peatland
fireshappened in Sumatra and Kalimantan. Severe peat fires occurred in 1997, 1998 and
2002. The smog was produced cause many problems with surrounding countries. Peat
fires do not only occur on the surface of the soil, but also creeping into the subsurfaces.
Fires in peat layers could spreading radially due to peat structure which is the remains of
dead plant roots. This land fires emit aerosols containing carbonaceous compounds,
including black carbon (BC elemental carbon (EC) and organic carbon (OC). The
impact of these particulate components tohealth and the environment is very important.
In this study were analyzed particulate emissions by burning peat PM2.5 parameters,
BC/EC and OC. Particulate emissions were taken using MiniVol TAS with Teflon filters
and Quartz fiber filters. Particulate was analyzed using BOECO-Germany Semi-
Microbalance, Smoke Eel Reflectometer Model 43D, and DRI Carbon Analyzer Model
2001 OC/EC. The results showed that the surface peat samples combustion was emitted
in average concentration of 7,467.29±3,976.26?g/m³ PM2.5. While the subsurface peat
samples combustion was emitting 5,693.55±2,137.15?g/m³ PM2.5. The PM2.5 contain
96.49±35.98 ?g/m3 BC. In PM2.5, OC and EC were in average contribution of 70.27%
and 1.85%, respectively. The results may helpful to predict the potential effect of air
pollution case on a particular location so that the mitigation of peat fires could be
optimized. |
