ANALISIS KANDUNGAN KARBON PADA EKOSISTEM MANGROVE JENIS Rhizopora mucronata dan Sonneratia alba DI KAWASAN CAGAR ALAM PULAU ENGGANO
Climate change caused by increased carbon dioxide (CO2) emissions can be mitigated through the role of mangrove ecosystems as effective carbon sinks and storage (blue carbon). Enggano Island possesses relatively pristine mangrove forests, making it an important site for carbon stock analysis. This study aims to analyze the carbon content within the mangrove ecosystems of the Enggano Island Nature Reserve through vegetation identification, estimation of biomass carbon stock, and assessment of organic carbon content in sediments. The research employed a purposive sampling method across five study stations Sungai Bahewo, Teluk Klowe, Kioyo 1, Kioyo 2, and Tanjung Laksaha. Observed parameters included vegetation composition, above- and below-ground biomass, and sediment organic carbon content. The results identified two dominant mangrove species, Rhizophora mucronata and Sonneratia alba. The highest vegetation density was recorded at the Sungai Bahewo Nature Reserve (967 ind/ha), while the lowest was at Tanjung Laksaha (567 ind/ha). The highest carbon stock was obtained from above-ground biomass (11,982.97 ton/ha), followed by below-ground biomass (4,798.64 ton/ha) and sediment carbon with an average of 61.86 ton/ha and organic carbon content of 3.06%. Variations in carbon stock were influenced by mangrove species, stem diameter, and substrate type. These findings indicate that the mangrove ecosystems of Enggand Island have significant potential as carbon sinks and play a vital role in global climate change mitigation.
