The Potency of Biomass and Carbon Stocks under Agroforestry Dusung Areas in Maluku Indonesia

The increasing carbon emission caused by human and industrial activity has a destructive impact on earth. Agroforestry as one of model in forest management has played an essential role in carbon sequestration through vegetation growth. Information about the potency of biomass is important to evaluate carbon stock in the forest. The study was conducted to determine the potential of stored biomass and carbon stocks managed by the Dusung of agroforestry Toisapu Negeri Hutumuri, Sirimau Protected Forest in Ambon. The study was conducted using nondestructive method in three main plots (PU) for observing vegetation at the level of poles, trees, understorey, litter, and dead organics. Observation parameters include plant biomass stocks and carbon stocks potency. The calculations for tree and pole level biomass stocks were 50.78 kg /m2, the understory was 0.26 kg/m2, litter 4.343 was kg / m2, and dead organics was 4.41 kg/m2. Assuming the amount of carbon uptake of 46%, the amount of carbon stored for trees and poles is 233.58 tons C/ha, the understorey is 1.196 tons C/ha, litter is 19.977 tons C/ha, dead organics are 20.286 tons C/ha, and soil has 0.044 tons/ha. The total value of carbon stocks stored above the soil surface in the agroforestry Dusung system in Ambon is 275. 092 tons C/ha and its good contribution on mitigation of climate change.
