Stok Karbon pada Ekosistem Mangrove di Desa Pangkalan Siata Kabupaten Langkat

Abstract

The mangrove ecosystem plays a crucial role in climate change mitigation by storing large amounts of carbon. This study aims to analyze carbon stocks in the mangrove ecosystem in Pangkalan Siata Village, Langkat Regency. The method used is a non-destructive method with an allometric approach to estimate mangrove biomass and carbon stocks. Data collection was conducted at 10 research stations selected through purposive sampling based on vegetation density. The results of the study show that carbon sequestration in the mangrove ecosystem in Pangkalan Siata Village has a value of 1,035,416 tons of CO₂e, with an economic valuation under the mandatory market scheme amounting to IDR 227,294,654,857 and under the voluntary market scheme amounting to IDR 86,974,995,481. Environmental factors such as fraction and substrate category have a positive correlation with mangrove density, whereas temperature has a negative correlation with mangrove density. This research is expected to serve as a reference for mangrove conservation efforts and to raise awareness of the importance of this ecosystem in carbon emission reduction and climate change mitigation.
