Mangrove ecosystems are similar to other forest ecosystems in that they play a role in absorbing CO2 from the atmosphere. Mangrove ecosystems can store more carbon compared to most rainforests. This is because mangrove plants utilize CO2 for photosynthesis and store it in the form of biomass and sediments. The purpose of this research is to determine the potential of mangrove ecosystems in absorbing and storing carbon, particularly the content of below-ground carbon and Biomass from several locations on Lepar Island. The data collection method used systematic sampling, where the placement of sampling plots had regular distances from the sea to the land. Substrate samples were taken using a core sampler tool and analyzed using the Loss of Ignition (LOI) method to determine carbon content. The research results showed that the average soil density at all stations was 1.0 g/cm3. The average percentage of organic carbon at all stations was 0.09 C%. The average total carbon content at all stations was 105.73 tons/ha. Mangrove forests are capable of storing a large amount of carbon in both biomass and sediments.

Abstrak
Ekosistem mangrove sama halnya dengan ekosistem hutan lain yang memiliki peran sebagai penyerap CO2 dari atmosfer. Ekosistem mangrove mampu menyimpan lebih banyak karbon dibandingkan dengan kebanyakan hutan hujan. Hal ini dikarenakan tumbuhan mangrove memanfaatkan CO2 untuk fotosintesis dan menyimpannya dalam bentuk biomassa dan sedimen. Tujuan penelitian ini untuk mengetahui potensi ekosistem mangrove dalam menyerap dan menyimpan karbon terutama kandungan pada Belowground Carbon mangrove dan Biomassa dari beberapa lokasi yang ada di pulau lepar. Metode pengambilan data dilapangan menggunakan systematic sampling method, dimana penempatan plot sampling memiliki jarak yang teratur antar plot dari laut ke darat. Pengambilan sampel substrat menggunakan alat core sampler dan dilakukan dengan metode komposit. kemudian dianalisis kandungan karbon menggunakan metode Loss of Ignition (LOI). Hasil penelitian menunjukan nilai rata-rata densitas tanah seluruh stasiun yaitu sebesar 1,0 g/cm3. Nilai rata-rata presentase karbon organik pada seluruh stasiun yaitu sebesar 0,09 C%. Nilai rata-rata kandungan karbon total pada seluruh stasiun yaitu sebesar 105,73 ton/ha. Hutan mangrove mampu menampung kandungan karbon dengan jumlah besar baik di biomassa dan sedimen.
