Abstrak: Post mining land reclamation is one of the effort to increase carbon stock. Reclamation activities will recover the post-mining degraded lands. The objectives of this study were create an allometric of some tree species, estimate and compare the carbon stock on the land of PT. Antam UBPE Pongkor, West Java in 2001, 2002, and 2003 planting years. Biomass measurement of tree, pole, and sapling was done with non destructive method, while understorey, litter, and necromass was done with destructive method. The allometric which used in this study has the highest R2 value, so that all of allometric can be used for estimate tree’s volume. The result of this study show the highest potential carbon found in 2001 planting years, the potential carbon of this planting year is 107.14 ton/ha, and then 2003 planting years is 101.44 ton/ha, and 2002 planting years is 94.18 ton/hnd a. Carbon potential differences caused by composition, structure, stand density, and canopy coverage

Abstrak: Global Warming is one of the environmental issues that are currently flare hit many areas in the world. The effects of global warming must be mitigate, so it attempts to do is to reduce emissions or increase sequestration of carbon and carbon stocks. Efforts to increase the absorption of carbon stocks indirectly by mining companies in the form of implementation of mined land reclamation. The role of mined land reclamation activities is actually important in reducing greenhouse gas emissions, it is necessary to study carbon stock in the biomass of reclamation area. One aspect of the research is important to know the potential of the carbon stored in the reclamation area. The potential of the carbon stored onsite reclamation area can be measured of the success of reclamation activities, one of which was done by PT Antam UBPE Pongkor. The objective of this study was to quantify the carbon stocks on the reclamation area of PT Antam UBPE Pongkor. The research activities was carried out using non-destructive method, which estimates the carbon content without cutting the trees by using parameters such as diameter at breast height and tree height. The study shows that the reclamation area PT Antam UBPE Pongkor above ground contains biomass amounted to 127.89 ton ha-1 and the carbon content of 58.77 ton ha-1. The result consist four potential of biomass, which is standing forest, litter, lower plants and necromass with each biomass and carbon content of 122.75 ton ha-1, 2.45 ton ha-1, 1.28 ton ha-1, 1.41 ton ha-1 and 56.41 ton ha-1, 1.13 ton ha-1, 0.59 ton ha-1, 0.65 ton ha-1. This study is expected to provide data and information about carbon storage in any location belonging to the reclamation area of PT Antam UBPE Pongkor.
