Analisis Hubungan Suhu Permukaan, Evaporative Fraction, dan Bowen Ratio dengan Hotspot sebagai Indikator Kebakaran Lahan

Abstract

Landfire is a burning incident that swoop down the vegetation area. Landfire in Indonesia has been an annual incident specially in Sumatera and Kalimantan. Landfires often symbolized with hotspots in that area, because that hotspots generalized with the firespots if looked by remote sensing method. The differentiation parameters were parameter from convertion metadata Landsat 8 with resolution 1 km x 1 km. This resolution used for generalize with the resolution of MODIS fire data that is 1 km x 1km. The two of image data are from 2013 in path/row 126/61. Using parameter surface temperatures (TS), Bowen ratio (β), and evaporative fraction (EF). The result from relation between TS and hotspot is the climb down trend with R2 5.42%. While the result from relation between EF dan hotspot is the climb down trend with R2 4.94% and the result from relation between β and hotspot is the climb up trend with R2 6.31%. The result of t-test and F-test between these parameters and hotspot is these parameters can’t used alone to estimated hotspot. Because for estimating hotspot can’t use only these parameters but the others too.
