Abstract

The aims of this study were (1) to analyze the relationship between vegetation index and biomass content- (2) determine the potential for anthropogenic emissions produced by Malang City- and (3) knowing the resultant ability of vegetation and potential anthropogenic emissions. This research was conducted using remote sensing from Landsat 8 imagery with the NDVI method. Furthermore, a survey was conducted to measure the biomass content and to determine the ability of vegetation to reduce emissions (SDGs13). NDVI and biomass content have a strong and positive relationship with the variability of biomass content on NDVI of 64%. The calculation of potential anthropogenic CO2 emissions includes the respiratory sector and the transportation sector by multiplying the number of residents and the number of vehicles against the emission factor determination. The potential for anthropogenic emissions of Malang City in 2021 is 1,041,555.43 Tons of CO2 or equivalent to 118,899.02 Kg CO2.hour-1. It is predicted that the anthropogenic emission potential of Malang City will decrease by 7.75% in 2031. The percentage of Malang City vegetation land cover in 2021 is 51.3% of the area of Malang City of 110.06 Km2. The percentage of Malang City vegetation land cover in 2021 is 51.3% of the area of Malang City of 110.06 Km2 and has the ability to reduce emissions of 2,046,928.7 Tons of CO2 or equivalent to 233,667.7 Kg CO2.hour-1.The existing vegetated land cover of Malang City in 2021 is able to reduce the total emissions produced by anthropogenic Malang City.
