ABSTRACT
Emissions of CO2 that accumulated in the atmosphere causes global climate change. To reduce the impact of climate change, one of the efforts is increased carbon sequestration. The mangrove ecosystem has ecological function as reducing carbon through sequestration process (C-sequestration). Aimed of this research to calculate the density, carbon content and absorption ability CO2 as well as knowing the correlation of mangrove density with carbon sequestration in mangrove. The method used in this research is use non destructive sampling method with allometric equation. The approach allometric equations were used that tree biomass allometric models for the type or types of mangrove ecosystems that are already available or developed in other locations. The measurement results of mangrove density in planting area 2004, 2007 and 2010 were 1,460 individuals/ha, 1868 individuals/ha, and 2128 individuals/ha. Biomass at the planting area in 2004 amounted to 206.77 ton/ha (103.39 ton C/ha, and absorbs 379.09 ton CO2/ha). Planting area in 2007 have biomass 293.73 ton / ha (146.86 ton C/ha, and absorbs 538.50 ton CO2/ha), and the planting area in 2010 have biomass 260.02 ton/ha (130.01 ton C/ha, and absorbs 476.67 ton CO2/ha). Based on the research results, the density of mangrove species and age are factors that influence the amount of tree biomass. The results of regression-correlation analysis showed, if mangrove density change significantly, it can influence the mangrove ecosystem in carbon sequestration and absorb CO2 from the atmosphere.
