This research aims at measuring carbon (C) stock of gmelina (Gmelina arborea Roxb.) agroforestry system and its carbon diynamics due to several harvesting rotations. Observation was conducted during March – October 2014, on 17 plots in private forest, located in Tasikmalaya and Banjar District, West Java Province. The C-stock measurement followed Rapid Carbon Stock Appraisal Method (RaCSA) with some additional analysis. The dynamic of C-stock was measured based on biological rotation, technical rotation-1 (harvesting at tree diameter of 15 cm) and technical rotation-2 (harvesting at tree diameter of 20 cm). The result of the study shows that average of C-stock in gmelina agroforest stand is 170 ton/ha, consisted of 64 ton/ha above ground C and 106 ton/ha below ground C. Biological rotation (8 years) results in maximum C-stock of 15 ton/ha  at harvesting time, while the time averaged-C stock is 7 ton/ha/year.Technical rotation-1(14 years) and technical rotation-2 (24 years) result in maximum C-stock of 23 ton/ha and 28 ton/ha respectively, while the time averaged-C-stock are 12 ton/ha/year and 18 ton/ha/year respectively.Keywords: agroforestry system, biological rotation, gmelina, technical rotation
