Mangrove forest are able to store carbon from the air through photosynthesis by converting CO2 into biomass based on ecological function. The better ability of mangrove forest to absorb CO2 has not been widely recognized by the wider community, this is one of the reasons why people do not consider the existence of mangrove forest and not maintain their sustainability. Based on that reason, this research was conducted by estimating carbon stock on aboveground biomass (stem), belowground biomass (root), litter and mangrove sediment. Mangrove forest on the North Coast of Cawan Island which are classified as good then can be also to calculate their ability to absorb CO2 and carbon economic value.
The aim of this research is to (1) analyze community structure; (2) estimate the carbon stock on aboveground biomass, belowground biomass, litter and sediment; (3) estimate the ability to absorb CO2 and (4) estimate the economic value of CO2 absorption by mangrove forest on Cawan Island. Community structure analysis based on relative density, relative frequency, relative dominance and important value index. Stem and root biomass was measured using the allometric method, litter biomass was measured using the dry weight weighing method and sediment biomass was measured using the Loss on Ignition (LOI) method.
The result showed that the mangrove species found were R. apiculata, N. fruticans, E. agallocha, X. granatum, S. alba, S. ovata, L. littorea and L. racemosa. The highest relative density by R. apiculata at Station V was 90. The highest relative frequency by R. apiculata at Station I and V was 60. The highest relative dominance by N. fruticans at Station V was 67.78. The highest importance value index by R. apiculata at Station I was 186.15. Estimated aboveground carbon (stem) of 34.56 tons/ha, belowground carbon (root) of 16.41 tons/ha, litter of 0.10 tons/ha and sediment of 32.91 tons/ha with an average carbon stock of mangrove forest is 83.98 tons/ha. The estimated ability to absorb CO2 is 187.10 tons/ha or 636,450.59 tons for the total on the North Coast of Cawan Island. The estimated economic value of carbon is IDR 149,809,099 ton/ha or IDR 509,599,619,024 for the total on the North Coast of Cawan Island.
Key words: Mangrove Forest, Carbon Stock, CO2 Absorption, Carbon Economic Value
