PENDUGAAN POTENSI BIOMASSA TEGAKAN DIKAWASAN HUTAN LINDUNG MENGGUNAKAN CITRA LANDSAT 8 DI DESA NUPABOMBA KECAMATAN TANANTOVEA KABUPATEN DONGGALA

Abstract

Biomass as the total amount of organic matter above the soil surface in trees expressed in kiln dry weight tons per unit area. However, the development of remote sensing technology allows indirect biomass measurements, namely to calculate and monitor biomass at the land cover scale. Based on this, it is necessary to use remote sensing technology using satellite imagery. This study aims to find out how big the potential for the amount of biomass using Landsat 8 imagery. This research was carried out for three months from January-March 2021 located in the Protected Forest area in Nupabomba Village, Tanantovea District, Donggala Regency. The method used in this research is the purpose sampling method, the allometric, NDVI and SAVI values in Landsat 8 imagery, and the results of the multiple linear regression analysis equation to determine the effect of the vegetation index on the estimation of biomass potential. Based on the results of testing the coefficient of determination, it is known that the R Square value is between 0.788 (78.8%) so it can be said that the independent variable (X) namely NDVI and SAVI has a contribution effect level of 78.8% on the dependent variable Biomass. The potential for standing biomass in the Protected Forest area by using the vegetation index of the biomass in the dense density class is 70,478.81 tons/ha, the medium density class is 43,820.63 tons/ha, and the rare density class is 4,407.39 tons/ha, with a total biomass of 118,706.83 tons/ha with an area of 1640 ha.
