Pendugaan Potensi Simpanan Karbon Tegakan Campuran Akasia dan Kayu Putih di Areal Reklamasi PT. Bukit Asam (Persero) Tbk

Abstract

Reclamation is an attempt to restore the appropriate post-mining land uses. Revegetation of land can be done by planting acacia and eucalyptus. One of the results of reclamation is the carbon content that absorbed and stored in biomass, so carbon storage can be expected from their biomass. The influence factors of biomass value are soil fertility, age of stands, vegetation developing stage, climate, composition and structure of stands. The result show that the biomass potency in exhauling area (block B) is 16,70 tons/ha is bigger than post mining area (block A) is 14,24 tons/ha. Estimation of potency of carbon storage is proportional to the biomass potency. Carbon storage in block A is 4,14 tons/ha and in block B is 5,56 tons/ha. The result show the ability of acacia and eucalyptus in storing carbon is not optimal yet.
