ABSTRACT: Among other greenhouse gases, Carbon dioxide (CO2) is a gas that generates the most accumulated heat energy in the atmosphere and it is the main factor to causes the greenhouse effect by humans. However, aboveground biomass (AGB) can be converted to carbon sequestration by multiplying the constant according to Intergovernmental Panel on Climate Change (IPCC) instructions where the estimation of biomass or carbon sequestration is still an interesting issue. This article presents the method for estimating aboveground biomass of dry deciduous dipterocarp forest with data from the Sentinel-2A satellite. Summary procedures are 1) conduct field survey by creating 24 sample plots size 20x20 m and measure the size and height of the trees to calculate for aboveground biomass, 2) analyze data from Sentinel-2A satellite by using MSAVI2 and FVC Model, and 3) figure out the relationship between the analysis results from Sentinel-2A satellite and field survey data by using a statistical method and carbon sequestration in the study area. The study result finds a relationship equation y = 4.93580.038x and finds that the study area of dry deciduous dipterocarp forest has aboveground biomass of 2,135.57 tons, which equals 187.407 tC, 3,680.31 tCO2eq, and 26.77 ha.
