Ekosistem mangrove memiliki fungsi ekologis sebagai penyerap dan penyimpan karbon. Mangrove menyerap CO2 pada saat proses fotosintesis, kemudian mengubahnya menjadi karbohidrat dengan menyimpannya dalam bentuk biomassa pada akar ,pohon, serta daun. Tujuan dari penelitian ini adalah untuk mengetahui total above ground biomass, belowground biomass, simpanan karbon atas, simpanan karbon bawah, dan karbon organik pada sedimen dasar di Hutan Mangrove Perancak, Jembrana, Bali. Sampling dilakukan dengan metode purposive sampling dengan dasar pertimbangan berupa jenis, kerapatan serta diameter pohon mangrove. Estimasi biomassa digunakan metode tanpa pemanenan dengan mengukur diameter at breast height (DBH, 1.3 m) mangrove. Simpanan karbon diestimasi dari 46% biomasa. Kandungan karbon organik pada sedimen diukur dengan menggunakan metode lost on ignition (LOI). Hasil penelitian menunjukkan total above ground biomass sebesar 187,21 ton/ha, below ground biomass sebesar 125,43 ton/ha, simpanan karbon atas sebesar 86,11 ton/ha, simpanan karbon bawah sebesar 57,69 ton/ha, sedangkan karbon organik sedimen sebesar 359,24 ton/ha. The mangrove ecosystem has ecological functions as an absorber and carbon storage. Mangrove absorbs CO2 during the process of photosynthesis, then changes it into carbohydrates bystoring it in the form of tree biomass. The aim of this research is to know the total of above ground biomass, below ground biomass, upper carbon storage, lower carbon storage, and sediment organic carbon in Perancak Mangrove Forest, Jembrana, Bali. The selection of sampling location using purposive sampling method with consideration of type, density and diameter of mangrove. The estimatorion of biomass using the method without harvesting by measuring diameter at breast height (DBH, 1.3 m) mangrove. Carbon deposits are estimated from46% of biomass. The organic carbon content of sediment was measured using the lost on ignition (LOI) method. The results showedthat the total of above ground biomass of 187.21 ton / ha, below ground biomass 125,43 ton / ha, upper carbon store of 86,11 ton / ha, lower carbon store of 57,69 ton / ha, and organic carbon sedimen to 359.24 tons / ha.
