Persamaan Alometrik Biomassa dan Massa Karbon Akar Pohon Jati (Tectona grandis Linn f.) di KPH Balapulang, Kabupaten Tegal, Jawa Tengah
Abstract
Global warming isa phenomenon where the global temperature is increasing due to the green house effect (GHE) resulted from the increase in GHE emission in the atmosphere. Forests play an important role in climate change issues, especially for absorbing CO2 gas from the atmosphere. Tectona grandis Linn. f, known as jati (teak) in Indonesia, is the kind of wood which economically has a high value and is in high demand. Teak is mostly grown on Java Island; therefore, it is necessary to find out the biomass and carbon mass. The carbon is stored in the stem, branch, twig, leaf, and root. Out of the five parts, the hardest is to estimate biomass and carbon mass in root because it is located in the ground and has unreachable root branches, so that it takes a longer time and much money to count biomass and carbon mass in root. After learning the relation model of alometric equation of biomass and carbon mass in root, it is expected that the model can be used to estimate biomass and carbon mass in a tree without having to dig the root. The equation models of alometric biomass in teak root in this study showed that: the relation between root biomass and total tree biomass above ground was BA= 0,221BT0,936, the relation between root biomass and stem biomass was BA= 0,489BU0,842, and the relation between root biomass and the biomass of branch and twig was BA=1,448BC1,21, therelation between root biomass and leaf biomass was BA= 5,977BD1,25. The equation models of alometric carbon mass in teak root in relation with the carbon mass in the tree parts were as follows: root carbon mass and total tree carbon mass above ground was MA= 0,2033MT0,947, root carbon mass and stem carbon mass was MA= 0,430MB0,853, root carbon mass and the carbon mass of branch and twig was MA= 1,448MC1,22, and root carbon mass and leaf carbon mass was MA= 5,977MD1,28. Based on the models, the best model for estimating teak root biomass was BA= 0,221BT0,936 and the best model for estimating the carbon mass of teak root was MA= 0,2033MT0,947.
