Abstract:
Change in natural conditions are caused by several things, one of which is the
increase in amount of CO2 in atmosphere. The cause of increase in CO2 is due pollution so trees
and forests begin to decrease in area. Plants are able to absorb carbon dioxide for the process of
photosynthesis to reduce carbon dioxide from atmosphere. The way to reduce this impact is by
planting plants and maintaining land use change. Vegetation absorbs CO2 is stored in plant body
in the form of biomass in the plant body. Land cover is a field covers the earth's surface, the
difference in land cover causes carbon stored will also be different. Purpose of this study was to
analyze amount of carbon in forest land cover, settlements and open land in Mandiangin Barat
Village and also to calculate the economic value of carbon stocks. Method used in this research is
non destructive and destructive (for litter and undergrowth). Plots were made on each land cover
measuring 20m x 100m. Results showed that the residential environment in Mandiangin Barat
Village was very good because carbon stock (tons/ha) around the settlement was higher than
forest land. The result of this research is that the carbon in forest land cover, settlements and open
land in West Mandiangin Village amounted to 158,282,539 tons. Carbon in forest is 157,392.434
tons, residential land is 741,879 tons and open land is 148,226 tons. Overall economic value of
carbon stocks on forest land, settlements and open land is IDR 11,447,428,478,224
