Abstract

Carbon dioxide (CO2) is the most significant greenhouse gas causing global warming. Mixed gardens are one type of artificial vegetation in Indonesia that helps to mitigate global warming. The construction of Jatigede Reservoir leads to a reduction in agricultural area and plant cover, affecting tree stands' ability to absorb CO2 from the atmosphere. Remote sensing, GIS, and NDVI analysis were used in research to estimate stored carbon stocks in Jatigede District, Sumedang Regency. These methods can improve the accuracy and efficiency of carbon stock estimates by providing preliminary data on the role that tree stands possess in absorbing carbon in the atmosphere. The purpose of this study was to ascertain the potential for carbon storage in mixed plantation tree stands as well as the amount of carbon stored in each village within Sumedang Regency's Jatigede District. The Normalized Difference Vegetation Index (NDVI), a geographic information system, and non-destructive sampling were the quantitative methods used in the research. The research's findings indicated that the estimated carbon stock in Jatigede District, Sumedang Regency, are 55,680.17135 tons/ha. Of the 12 villages in Jatigede District, Karedok Village has the largest carbon stock, at 13,368.05 tons/ha, while Sukakersa Village has the smallest, at 156.90 tons/ha.
