Global warming is a direct impact of increased of carbondioxide (CO2) gas emission in the atmosphere. One knwon as the source of CO2 gas emissions is caused by burning material containing the element of carbon (fossil fuel combustion) of industry. One attempt to reduce CO2 gas emission levels in the atmosphere is to determine the potential amount of CO2 absorption by forests or stands. To find out how much CO2 absorption, needs a head count of forest carbon stocks. This study aims to calculate the carbon storage and CO2 gas absorption at Tabo-Tabo Teaching Forest and at the reclamation area of PT. Semen Tonasa. The method used in this study is a non-destructive method to estimate carbon stands. The analysis showed that the amount of carbon stored in biomass of Tabo- Tabo Teaching Forest is 14.77 tons/ha/year or equal to 54.21 tons/ha/year of CO2 absorption. Based on the effective area of Tabo-Tabo Teaching Forest which is 595.94 ha, the total amount of CO2 absorption at Tabo-Tabo Teaching Forest is equal to 32292.53 tons/year or 0.91% of the annual CO2 gas emissions of PT. Semen Tonasa which is 3,530,248.35 tons/year. Carbon stored in the biomass of stands in the reclamation area of PT. Semen Tonasa is 11.18 tons/ha/year or equal to 41.03 tons/ha/year of CO2 absorption. Based on the total area of reclamation which is 38 ha, the amount of CO2 absorption of PT. Semen Tonasa is 1559.22 tons/year or 0.044% of the annual CO2 gas emissions of PT. Semen Tonasa. Based on these results, the total area of stands needed to absorb the CO2 gas emission of PT. Semen Tonasa is 86093.40 ha. Each type of plant will produce a different amount of biomass. The selection of plants to be important to increase the absorption of CO2. Types of plants that contain large biomass will have a high absorption rate of CO2. Five types of plants that contain the highest biomass at Tabo-Tabo Teaching Forest are Vitex pubescens, Pterocarpus indicus, Dracontomelon dao, and Tectona grandi, and Vitex copassus. While in the reclamation area of PT. Semen Tonasa, plant species that have the highest absorption for CO2 are Gmelina arborea, Albizia falcataria, Tectona grandis, Samanea saman, and Swietenia mahogany.
