Ekosistem mangrove merupakan salah satu lahan basah pesisir yang berperan penting dalam siklus karbon global terutama karena kapasitas penyimpanan karbonnya yang tinggi. Estimasi penyimpanan karbon menjadi penting sehingga penelitian ini bertujuan mendapatkan informasi mengenai cadangan karbon pada ekosistem hutan mangrove di Pulau Lepar, Kabupaten Bangka Selatan. Metode pengambilan vegetasi dan biomassa dilakukan secara systematic sampling method dan pengukuran biomassa pohon mangrove mati mengacu pada SNI (7724:2011), sedangkan pengambilan sampel substrat dilakukan dengan metode komposit yang selanjutnya dianalisis kandungan karbon menggunakan metode Loss of Ignition (LOI). Hasil penelitian terdapat sebanyak 11 spesies mangrove pada keempat stasiun dengan Rhizophora apiculata dan Sonneratia alba yang selalu ada pada setiap stasiun kecuali pada stasiun IV. Kerapatan rata-rata ekosistem mangrove di Pulau Lepar masuk dalam kriteria kerapatan sangat padat (1.689,75 ind/ha). Nilai rata-rata aboveground biomass sebesar 87,55 ton/ha dan stok karbonnya sebesar 41,15 ton/ha, dan yang tertinggi pada stasiun IV sebesar 182,88 ton/ha untuk aboveground biomass dan 85,95 ton/ha untuk stok karbon sedangkan terendah pada stasiun II yaitu 30,90 ton/ha untuk aboveground biomass dan 14,52 stok karbonnya. Potensi stok karbon yang ada dapat dijadikan upaya pentingnya konservasi dan restorasi ekosistem mangrove dalam menghadapi mitigasi perubahan iklim.

The Coastal Area is an aquatic ecosystem that has high productivity and is able to support the survival of various aquatic biota and is often used as a place for various daily life activities by residents including fishing activities, tourism activities and mining activities. The aims of this study were to analyze the density, diversity, uniformity and dominance of molluscs (gastropods and bivalves) and to analyze the relationship between the density of mollusks (gastropods and bivalves) and environmental factors. The sampling technique used the 1x1m² Quadratic Transect method. The results obtained at all observation stations were 13 types of gastropods and 9 types of bivalves. Diversity is in the low to medium category which ranges from 0.8760 to 2.1655. The uniformity of gastropods and bivalves was moderate to high which ranged from 0.5291-0.8715, and was dominated by Pinerella cingulata gastropods. The results of principal component analysis (PCA) showed that the density of gastropods showed the parameters of depth, silt and clay, and the density of bivalves showed the parameters of brightness, salinity and sand which had a high affinity with density which was a limiting factor for the distribution or abundance of gastropods and bivalves.

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. Keywords: Belowground, Karbon, Lepar Island 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%.
