Analisis Neraca Air Klimatologis Dan Kebakaran Lahan Gambut Kepulauan

Peatland fires are an actual problem in Indonesia especially in the PHU
(Peat Hidrology Unit) area on the islands of Sumatra and Kalimantan always
have the same problem in recent years. The water balance analysis and peatland
fires in this study were carried out spatially and temporally. The spatial analysis
in this study is an analysis related to the distribution of hotspots using Landsat
imagery and the patterns formed as an indication of the area of fire scars caused
by the hotspot data. Meanwhile, temporal analysis can be interpreted as a
frequency of re-recording of hotspot data, Landsat satellite imagery and water
availability within a predetermined period of time. This spatial and temporal
analysis is expected to provide a bright spot on the characteristics of peatland
fires that occur every year, so that prevention efforts can be carried out quickly
and precisely.
The goals of this study to conduct a spatial and temporal study of the
characteristics of fire events compared to the analysis of the water balance in
peatlands with several periods of fire incidence based on the number of hotspots
(2001-2020) with a confidence level of >60% so that the trend of peatland fires
from year to year. Archipelagic peat is peat located in an area bounded by the sea
and has a smaller catchment area than mainland peat. This research was
conducted using the Landsat image delineation method based on the distribution
of hotspot data with on/off layer technique using Geographic Information System
(GIS). The parameters analyzed in the Rangsang Island KHG and Bengkalis
Island KHG included analysis of the distribution of hotspot data, analysis of fire
characteristics (area of fire, duration of fire and rate of fire), analysis of the
relationship between fire characteristics and analysis of climatological water
balance in each KHG.
The fires at KHG Pulau Rangsang and KHG Pulau Bengkalis occurred
over two periods annually. The fires in the first period produced a wider burned
area than the fires in the second period. This is because the ability of peat to hold
water is reduced due to the dry season. Peatland fires have a correlation with the
water balance condition, when the water balance condition is a water deficit, the
statistics show the occurrence of fires at that location. The water balance in
deficit conditions has a high risk of peatland fires, which is supported by the
factors that cause fires, namely fire and flammable dry fuel.
