Estimation Biomass, Carbon, and Carbon dioxida Absorption a Forest Management Unit of Lawu Manunggal, Sukowidi and Sumbersawit Villages

Today's increase in global warming is very influential on the activities of living things in the world. The imbalance in the concentration of greenhouse gas emissions is the cause of extreme weather events such as floods and droughts, and extreme weather. One effort that needs to be done with reforestation one of the alternatives is planting activities in the community forest area. The aim of the study is to calculate the estimated biomass, carbon content and the ability of community forests to absorb carbondioxide in Sukowidi and Sumbersawit Village which are included in the Forest Management Unit of Lawu Manunggal in Magetan Regency. The method used is an inventory of community forest stands with a sampling intensity of 10%, the amount of biomass is done by felling on the types of stands that exist, in various kinds of plant organs, the calculation of carbon content is carried out by Walkley and Black methods. The results of the research on the average potential of community forests covering an area of 330.95 Ha are for Sengon (M3/Ha) 32.154, Mohagony, 112.878, mindi 21.272 and teak 24.544 or a total of 191.279 m3 / ha. Biomass potential is 315, 755 tons /Ha or a total of 110, 475, 394 tons. The average carbon content is 155, 257 tons C/ha or the total available is 54, 132, 943 tons of carbon. The ability of community forest carbon dioxide (CO2) absorption by 567, 793 tons of CO2/Ha, with the area of management of community forests capable of absorbing CO2 content of 198.667, 9 tons of C02
