Estimation of biomass potential, carbon stocks, and carbon sequestration of Trigona sp honey bees feed

Abstract

This study aimed to determine the biomass potential of Trigona sp honey bees in Bontotiro subdistrict as well as its carbon stock and carbon sequestration. The research was carried out for two months starting from May to June 2021, located in the sub district of Bontotiro, district of Bulukumba. The biomass measurement was carried out by making 11 plots with a size of 20 x 20 for the tree level, 10 m x 10 m for the poles level, and 5 m x 5 m for the sapling level. Tree biomass was calcula ted using allometric equations. Measurement of carbon stocks was carried out by multiplying the total biomass with the percentage value of carbon content of 0.47, while the carbon sequestration was calculated by multiplying the average annual growth of biomass with the conversion rate of 1.4667 obtained from the photosynthesis equation. The results showed that the potential of biomass of tree, poles, and sapling levels were 4.5, 1.4, and 0.3 tons/year, respectively. The carbon stocks of the tree, poles, and sapling levels were 68.6, 13.7, and 1.8 tons/year, respectively. The carbon sequestration of the tree, poles, and sapling were 6.6, 2.1, and 0.56 tons/year, respectively.
