Forest inventory is conducted to determine the potential of stands, including timber volume and carbon stocks, for the preparation of forest management plans. Forest inventory needs to be conducted with certain accuracy by considering the availability of costs, energy, and time. This study aims to calculate and determine the sampling intensity that produces the best sampling accuracy for estimating carbon stocks and estimate the potential for biomass, carbon content, and CO2 absorption in the Sido Maju I farmer group’s working area.
This research was conducted by simulating the distance between measuring plots and the area of measuring plots. Simulations were conducted on 41 measuring plots made by systematic sampling with random start with a combination of distance between measuring plots of 50 × 50 m, 100 × 100 m, 150 × 150 m, and 200 × 200 m and measuring plot area of 0,02, 0,04, and 0,1 ha. Carbon stocks potential was calculated by non-destructive sampling method using allometric equation and BEF value approach.
This research resulted in a large sampling intensity that can be used in forest inventory to estimate carbon sequestration potential is 2% with the resulting accuracy of 13,77% for allometric equation and 0,5% with the resulting accuracy of 14,92% for BEF. Potential biomass, carbon content, and CO2 absorption in the Sido Maju I Farmer Group’s working area with allometric equation were 70,95 – 93,60 tons/ha, 33,35 – 43,99 tons/ha, and 122,38 – 161,46 tons/ha. The average CO2 absorption with a stand age of 25 years is 4,89 – 6,46 tons/ha/year.
