ANALYSIS OF VEGETATION AND MANGROVE BIOMASS TO TACKLE CLIMATE CHANGE IN EASTERN INDONESIADEBBY VEMIANCY PATTIMAHU, LUTFIA I. LITILOLY AND GUN MARDIATMOKO
Mangrove forests are primary producers that can absorb carbon with greater intensity than land plants. This is because mangroves photosynthesize chemically with the process of assimilation of CO2 gas (carbon uptake). The study of biomass content, especially mangrove forests, is currently important because it is related to climate change management. The purpose of this study is to analyze 3 types of dominant mangrove vegetation and to find out the amount of biomass content in the Gulf of Kotania. The methodology used is the Importance Value Index (IVI) to determine the type of vegetation while to calculate the amount of seedling biomass with destructive sampling techniques while the pole and tree level uses allometric equations that have been available previously. The results showed mangrove forests in the Gulf of Kotania, there were 10 species and the dominant species was R. apiculata both at the tree and seedling level with IVI values of 180.024% and 231.004%. The average of all mangrove forest biomass in Kotania Bay (eastern Indonesia) starting from seedlings to 137.03 tons / ha with details of 3.03 tons / ha seedlings, 84.10 tons / ha poles and 49.90 trees ton / ha.
