Abstract

Mangroves are referred to as coastal forests or brackish forests, coastal forests which mean forests that live in coastal areas (coastal) which are influenced by tidal areas and coastal land. Mangroves have an important role in the absorption and storage of carbon, the amount of carbon contained in a tree is influenced by the ability of the tree to absorb carbon from the environment by the process of photosynthesis or known as the sequestration process. The purpose of this study was to identify the types of mangroves on the coast of Tatengesan and determine the carbon storage in the biomass of mangrove trees on the coast of Tatengesan. Data collection on mangrove tree vegetation was carried out in 3 transects, on the left, right and middle of the mangrove ecosystem on the Tatengesan coast. The transects were drawn perpendicular from the sea to the coast according to the thickness of the mangroves at the site. One transect has three quadrants, with a size of 10 m x 10 m. For how it works, the transect is pulled 100 m from the sea to the beach, then the quadrants are measured 10 m x 10 m using a plastic rope as a marker, and the quadrant positions are placed randomly and for 25 m intervals. The results of this study provide information that there are 3 types of mangroves, namely Rhizophora apiculata, Rhizophora mucronata, and Bruguiera gymnorhiza, the value of mangrove biomass content ranges from 69.2 - 118.61 tons/ha, and the value of carbon storage in mangrove biomass. ranged from 32.52 to 55.75 tons/ha. Future research is expected to obtain time series data on the amount of carbon stored in a certain time period.
