Biomass density and carbon stock of tropical community forest area at FMU Lawu Manunggal-Panekan-Magetan district

Forest is a natural element that can absorb CO2 in large quantities. This is due to the existing vegetation in the forests bind CO2 while the process of photosynthesis and store it in the form of biomass. So that, the existence of forests affect the prevention and handling of global warming on earth. This research aims to measure the biomass density and carbon stock of tropical community forests area at Sumberdodol and Tapak Villages of FMU (Forest Managemen Unit) Lawu Manunggal – Panekan – Magetan District. The research method for inventory of individual trees in forest stands uses finger circle plot of 0.05 Ha. Its intensity is 5%. Destructive Biomass Measurements while analyzing carbon stock uses titration method of Wallky and Black. Result of research Biomass density of forests are Melia 61,288,649 kg/Ha, Mahogany 97,472,875 kg/Ha, Teak 88,925,376 kg/Ha, and Albicia 25,566,573 kg/ Ha. FMU Lawu Manunggal forest 206 Ahadiati Rohmatiah et al. area at Sumberdodol and Tapak is 276,33 Ha. Total Biomass density of Melia 1,225.77 tons, Mahogany 2,216.47 tons, Teak 1,778.51 tons, and albicia 511.33 tons. Total forest stands are 5,732.08 tons. The carbon stock average of Melia 28,806 ton/Ha, Mahogany 45,812 ton/Ha, Teak type 41,795 ton/Ha, and Albicia 12,016 ton/Ha. The total Carbon stock of Sumberdodol and Tapak Villages are 2,694.08 tons.
