Carbon stock estimation of mangrove ecosystem in the Kuta Raja Subdistrict, Banda Aceh, Aceh Province

Mangroves play a crucial role in maintaining the environmental balance through their ability to absorb and store carbon. This study aimed to analyze carbon storage in mangrove ecosystems, including aboveground biomass, belowground biomass, deadwood biomass, and organic soil material. The sampling method used in this research was purposive sampling to select three observation stations. The results of this research indicate that the biomass of mangrove tree stems in the Kuta Raja Subdistrict, Banda Aceh, was 117.9 tons/ha, which was the highest value compared to the roots at 47.2 tons/ha, and deadwood at 2.2 tons/ha, as part of carbon storage in mangrove plants. The carbon stock at the research site was highest in mangrove tree at 55.43 tons/ha, followed by mangrove root at 22.17 tons/ha, and deadwood at 1.04 tons/ha, and organic soil material at 2.7 tons/ha. The total carbon stock of the mangrove ecosystem was 81.37 tons/ha.
