Tujuan penelitian adalah melakukan analisis serapan karbon di vegetasi mangrove Pantai Ketapang, Lampung. Penelitian dilakukan dari Mei-Agustus 2023 di Pantai Ketapang, Provinsi Lampung. Pengukuran karbon tegakan, nekromassa, dan serasah dengan metode non-destructive sedangkan sedimen dengann metode Walkey and Black. Serapan karbon pada tegakan 2,19 kg C/m2-30,75 kg C/m2 dengan stok karbon 25,63 Ton C/Ha-300,97 Ton C/Ha, nekromassa 0,14 kg C/m2- 0,36 kg C/m2 dengan stok karbon 0,001 Ton C/Ha-0,003 Ton C/Ha, serasah  0,005 kg C/m2- 0,010 kg C/m2 dengan stok karbon 0,5 Ton C/Ha-0,10 Ton C/Ha, dan sedimen 22,92 kg C/m2-739,62 kgC/m2 dengan stok karbon 229,2 Ton C/Ha-7396,2 Ton C/Ha.
