“…The wood density ( ) of mangrove species ρ S. alba 3 is 0.79 g/cm (Kusmana et al 2018). It was the largest compared to other species, such as (0.67 Rhizophora 3 3 g/cm ) and Nypa (0.39 g/cm ) (Rahman et al 2020c). The total mangrove biomass on the coast of Negeri Waai was 156.39 tons/ha, consisting of 105.60 tons/ha above and 50.79 tons/ha below-ground biomass.…”

“…An ecosystem dominated by S. alba with a high density tended to have an immense potential for carbon stocks, and those dominated by a low-density Nypa would have low-carbon stores. Nypa-type had high water content and stored merely 39% of carbon (Rahman et al 2020c). The potential of carbon stocks could increase when the CMR government succeeds in mangrove rehabilitation.…”

The mangrove ecosystem contributes to climate change mitigation by absorbing carbon dioxide gas. The shoreline of Negeri Waai, Central Maluku Regency (CMR), becomes one of Indonesia's promising mangrove ecosystem habitats for carbon absorption. Therefore, this research aimed to assess the blue carbon potential of mangroves on the coast of Negeri Waai, CMR. This research collected data using the quadrant transect method (10 x 10 m) and placed randomly in 65 quadrants. The analysis of blue carbon potential used an allometric approach to above and below-ground biomass (AGB and BGB). The results showed that the total blue carbon mangrove stock on the coast of Negeri Waai was 73.22 ton C/ha, consisting of 49.44 tons C/ha above-ground carbon (AGC) and 23.78 tons C/ha below-ground carbon (BGC). Sonneratia alba contributed the most extensive carbon stock, namely 70.69 ton C/ha, consisting of 47.53 tons C/ha AGC and 23.16 tons C/ha BGC. This result was relatively low compared to the global average of blue carbon in mangroves, 134 ton C/ha. Based on this result, efforts were needed to restore the mangrove ecosystem, increase the potential for carbon absorption, and mitigate climate change.

“…The value of the carbon fraction gained using organic carbon content approach is 46.4% (Kauffman et al, 2011) that is approximately 0.42% lower than the value of the carbon fraction calculated based on the components that make up mangrove biomass of 46.82%. The estimated mangrove carbon stocks from palm species such as N. Fruticans is 39% can be used (Rahman et al, 2017;Rahman et al, 2020a).…”

Carbon stock in mangrove stands is estimated through the biomass approach multiplied by the value of the mangrove carbon fraction. Many researchers use the value of 47% as the carbon fraction value for all mangrove species which should be based on the actual carbon content value. The research was conducted using the literature review method using a database ScienceDirect and Google Scholar until 2022. The search strategy was carried out using keywords: mangrove biomass, mangrove carbon stock, organic carbon of mangrove, carbon fraction of mangrove biomass, and chemical composition of mangrove biomass. The results showed that the value of the carbon fraction with the approach of organic carbon content was 46.4% and lower than the value of the carbon fraction with the approach of compounds making up mangrove biomass, which was 46.82%. This value was contributed by carbohydrates at 26.20%, amino acids 2.97%, tannins 3.22%, lignins 3.38%, fatty acids 7.69%, triterpenoids 3.17%, and n-alkanes 0.19. %. The estimation of mangrove carbon stock in forests with homogeneous species can use the value of carbon fraction in each mangrove species, namely 46.3% for B. gymnorrhiza, 45.9% for R. apiculata, and 47.1% for S. alba. Meanwhile , a carbon fraction value of 46.82% can be used for all true mangrove species to estimate the carbon stock in forests with heterogeneous mangrove species.

Mangrove forests are important for human life and the surrounding environment, one of which is as a CO2 absorber and carbon storage. The North Coast of Cawan Island in Indragiri Hilir has a relatively good mangrove forest that is estimated to absorb and store more carbon. This study aims to (1) estimate the value of carbon storage in stands (stems), below-ground carbon (roots), litter, and sediment of mangrove forests, (2) estimate the CO2 absorption capacity of mangrove forests, and (3) estimate the economic value of absorption CO2 by mangrove forest on the North Coast of Cawan Island. The station determination method uses purposive sampling of five stations, each consisting of a transect with three plots measuring 10x10 m2. Measurement of stem and root biomass using the allometric method. Litter biomass measurement used the dry weight weighing method, and sediment carbon measurement used the Loss on Ignition (LOI) method. The result showed that average carbon storage in stems was 34.56 tons/ha, roots were 16.41 tons/ha, litter was 0.10 tons/ha, and sediment was 32.91 tons/ha. The estimated ability of mangrove forests to absorb CO2 is an average of 187.10 tons/ha or 636,450.59 tonnes for the entire North Coast of Cawan Island. The estimated economic value of mangrove forest carbon is an average of IDR 149,809,099 /ha or IDR 509,599,619,024 for the entire North Coast of Cawan Island.
