Amount Stock of Blue Carbon in Mangrove on the Area of Pt Arutmin Indonesia Kintap Mine Mekarsari Village, Tanah Laut Regency, South Kalimantan

Abstract

Mekarsari Village is located in the Kintap sub-district, Tanah Laut district, South Kalimantan Province, which is an area that has a 1.83 ha mangrove ecosystem. Mangrove ecosystem is one form of forest ecosystem that is unique and distinctive, found in tidal areas of coastal areas, beaches, and several small islands. In addition to the mangrove ecosystem, there is also a coral reef ecosystem with the condition of coral reefs around the marine waters of Kintap District ranging from low to moderate based on coral reef assessment criteria according to the Indonesian Environment Ministerial Decree, No. 4/2011, (Tony. F, et al 2021). The purpose of this study was to determine the amount of biomass and the amount of blue carbon stock in the mangrove ecosystem in Mekarsari Village. Data was collected by plotting the area and taking the upper sample to determine the amount of blue carbon stock through the results of laboratory analysis. The results of the study based on data collection in the field, namely the mangrove ecosystem in Mekarsari Village has a total biomass value of 98.52 tons/ha and the total amount of blue carbon stock is 84.72 tons C/ha.
