Struktur Komunitas Dan Potensi Cadangan Karbon Ekosistem Mangrove Di Pesisir Timur Jemaja Kabupaten Kepulauan Anambas

Mangrove ecosystem is one of three important ecosystems on the coast that can reduce CO2 gas in the atmosphere as a mitigation of global warming. Rising water temperatures and sea levels indirectly affect the presence of mangrove forests in coastal areas. Pressure on the mangrove ecosystem continues to occur, this can cause changes in the structure and quantity of mangrove ecosystems. The purpose of this study was to analyze the community structure and potential carbon stocks of mangrove ecosystems, to analyze the relationship of density and stem diameter to carbon biomass. The study was conducted from December 2019 to March 2020 by using a survey method. Determination of study stations using purposive sampling method. Density of mangrove vegetation was carried out by using a transect plot of size 10 m by 10 m. The number of observation stations was 6 stations with three plots per transect. Potential carbon stocks in the mangrove ecosystem are obtained from the calculation of carbon Above Ground Biomass, carbon Below Ground Biomass and carbon in sediments. Calculation of biomass carbon using the alometrik equation per species of mangrove.
The results showed that there were five species of mangroves, there were Rhizophora apiculata, R. mucronata, Bruguiera gymnorrhiza, Ceriops tagal and Xylocarpus granatum. The average density of pole was 1617 ± 392 ind / ha, the density of sapling was 1550 ± 578 ind / ha and density of seedling was 2739 ± 1089 ind / ha. No significant differences in density values was found (P> 0,05) between observation stations. Overall, the mangrove community in the East Coast of Jemaja, Anambas Archipelagoes Regency was dominated by R. apiculata species, which was indicated by the highest average Importance Value Index which was 120,80 %.
The mangrove ecosystem in this study has the potential of a large carbon reserve of 61,801.64 tons carbon with an average value of 464.29 ± 170.84 tons/ ha. This amount was equivalent to 123,603.28 kg of CO2 which can be absorbed by the mangrove ecosystem in the East Coast of Jemaja. Based on statistical analysis (Pearson correlation) show that the density had no relationship with the value of carbon biomass (P> 0,05), while the diameter of the stem had a very significant relationship (P
