Abstract

RIBKA CLARA SITORUS: Valuation of Economic Value Stands Above Ground Based Functions As well as Producing Oxygen Absorbing Carbon in Arboretum, Kuala Bekala University of Sumatera Utara, Deli Serdang. Supervision of AGUS PURWOKO and SITI LATIFAH. USU Arboretum is one of the collecting and growing trees in ecology can benefit directly and indirectly. For this study calculated the level of carbon stocks of trees, saplings, poles with the method of non-destructive ends and using allometric estimates from previous studies as well as by climate zone. Carbon stocks undergrowth in the arboretum USU, performed by direct harvesting method calculated wet weight, dry weight and number of individuals. Oxygen production was measured by estimation of canopy cover in the arboretum area USU. The results shown contribution of the arboretum USU for absorbs carbon was 45,926 ton C with priced potential of economic from market priced a carbon on the avarage was Rp 5.150.968,30 USU arboretum other functions to produce oxygen which 2.038,144 liters/days at the market price of Rp 50.953.600
