Potential of carbon stock on red jabon stand (Anthocephalus macrophyllus (Roxb.) Havil) in Tampinna Village, Angkona District, Luwu Timur Regency

Abstract

In addition to producing wood as a raw material for construction, pulp and firewood, forests also serve as carbon sinks so they have an important role in the global carbon cycle. Red jabon is a fast-growing plant species, so it is suspected to have high carbon absorption. The purpose of this study is to know the potential of carbon content and increased uptake of carbon above the soil surface for species of red jabon (Anthocephalus macrophyllus (Roxb.) Havil) in the forest Tampinna village community. Methods of data collection in the field is done by census, that is data retrieval as a whole. In the sample tree, the diameter measured at breast height (dbh) and tree height (TBC). Furthermore, the resulting data was processed to determine the biomass produced by using allometric equations. Samples of 302 red jabon trees were obtained from six sites with four different age levels, which were three to six years old. Based on the result of paired observation test of red jabon biomass prediction by using volume formula gives bigger result than allometric equation. The average potential of total carbon uptake in red jabon stands is 19.57125 ton/ha. In general, there is a tendency that the older age of the tree stands to produce a large carbon content as well. Equation of relationship between age with carbon content in the form of quadratic.
