Abstract

Global warming is one of the important environmental issues that currently concern to various parties. Related to the phenomenon,  environmentalists begin  to worry what conditions of  earth will be if global warming continues. Forests has  important roles through  three ways;the first is  as a carbon pool, the second is as  a source of CO₂ and the third is as carbon sink. If the forest is properly managed, it will  be able to overcome the excessive amount of carbon in the atmosphere by storing carbon in the form of biomass which is either  above or below the ground surface. One forest stands whose carbon  can be assessed  is the forest plantation of  red meranti (Shorea leprosula Miq). This study aimed  to estimate the amount of biomass carbon  of litter and soil organic carbon in  the forest plantation of  red meranti (Shorea leprosula Miq). This study used proposive  system with composite of litter and soil sampling in the field by making a diagonal plot size is 100 × 100 meters, then make a plot of 1 × 1 meter as a plot for  litter and soil sampling which  is  the depth of 20 cm below the  stands  of red Meranti plantation. Based on the  results of the research, total biomass ranged between  31.72 and  61.14 ton / ha. The better an ecosystem of an in  area is, the more fertilezed that area will be and, indirectly the higher the litter carbon will be   produced.. Based on the results of litter carbon conten which  ranged from 11 to 23.5%. a year growing  plant gained 11%, while a 7 year growing plant gained  23.5%. The longer the age of the is,  the greater carbon   will be produced.  Based on the study’s finding, the  level of soil organic is low   ranged from   1.08 to 1.96%. The level of soil organic carbon shows that the longer the age  of the plant is, the  greater the level of content of  soil organic carbon.
