Mangrove ecosystems play an important role in maintaining coastal ecological balance, serving as coastal protection, providing habitat for various marine biota, and absorbing atmospheric carbon. Quantitative data on mangrove biomass and carbon stock in Wori Village are still very limited. This study aimed to estimate mangrove biomass and carbon stock potential as a contribution to climate change mitigation. A non-destructive method was applied by measuring Diameter at Breast Height (DBH) in the field. Biomass was calculated using the allometric equation of Komiyama et al. (2005) based on DBH and wood density values from the Global Wood Density Database (Zanne et al., 2009 in Malabrigo et al., 2017). Carbon stock estimation was obtained by multiplying biomass by a conversion factor of 0.47 (IPCC, 2006). Results identified four mangrove species: Avicennia marina, Rhizophora apiculata, Sonneratia alba, and Bruguiera gymnorrhiza. Sonneratia alba had the highest biomass and carbon stock (1,307.45 kg/100m²) due to its large stem diameter, while Rhizophora apiculata had the lowest (247.48 kg/100m²). Total carbon stock from one observation plot was 3,077.43 kg/100m². The mangrove area of Wori Village covers 39.56 ha (satellite imagery via ArcMap 10.8), yielding a total carbon stock of 12,174 tons or 307.74 tons C/ha. This value is higher than Sungaitohor Village (131.08 tons C/ha) (Antonius et al., 2017), Kawal Village (182.81 tons C/ha) (Heriyanto et al., 2020), and Bontang Mangrove Park (283.04 tons C/ha) (Rahmawani et al., 2025), demonstrating high ecological potential as a carbon sink that requires sustainable management.

Ekosistem mangrove memainkan peran penting dalam menjaga keseimbangan ekologi pesisir, bertindak sebagai perlindungan pantai, menyediakan habitat bagi berbagai biota laut, dan menyerap karbon atmosfer. Data kuantitatif tentang biomassa dan stok karbon mangrove di Desa Wori masih sangat terbatas. Studi ini bertujuan untuk memperkirakan biomassa dan potensi stok karbon mangrove sebagai kontribusi terhadap mitigasi perubahan iklim. Metode nondestruktif digunakan, yaitu mengukur diameter at breast height (DBH) di lapangan. Biomassa dihitung menggunakan persamaan alometrik Komiyama et al. (2005) berdasarkan DBH dan kepadatan kayu dari Global Wood Density Database (Zanne et al., 2009 dalam Malabrigo et al., 2017). Estimasi stok karbon dihitung dengan mengalikan biomassa dengan faktor konversi 0,47 (IPCC, 2006). Hasil penelitian menunjukkan empat spesies mangrove: Avicennia marina, Rhizophora apiculata, Sonneratia alba, dan Bruguiera gymnorrhiza. Sonneratia alba memiliki biomassa dan stok karbon tertinggi (1.307,45 kg/100m²) karena diameter batangnya yang besar, sedangkan Rhizophora apiculata memiliki yang terendah (247,48 kg/100m²). Total stok karbon dari satu plot pengamatan adalah 3.077,43 kg/100m². Luas hutan mangrove Desa Wori adalah 39,56 ha (citra satelit melalui ArcMap 10.8) menghasilkan total stok karbon sebesar 12.174 ton atau 307,74 ton C/ha. Nilai ini lebih tinggi daripada Desa Sungaitohor (131,08 ton C/ha) (Antonius et al., 2017), Desa Kawal (182,81 ton C/ha) (Heriyanto et al., 2020), dan Taman Mangrove Bontang (283,04 ton C/ha) (Rahmawani et al., 2025), menunjukkan potensi ekologis yang tinggi sebagai penyimpan karbon yang perlu dikelola secara berkelanjutan.
