Enrichment is a planting activity beyond log-over area which has less the natural regeneration of commercial plant species. Enrichment on Indonesia Selective Cutting and Planting Silvicultural System (TPTII) aims to increase the productivity of log over area (LOA) by Line Plantation System. Line Planting System causing intensive management by open planting line and purposed species usage. Growth in Line Plantation System needs much nutritions for its growth. Nutrition returns through litterfall and decomposed litterfall on TPTII system was essentially notified. Research aimed for knowing litterfall production and litterfall decomposition in plantation line and inter plantation line at log over area, on one year, five years, ten years plant age also natural forest as control treatment at PT Sari Bumi Kusuma. The research was conducted on September 2010 to Februari 2011. Littertrap used for calculating litterfall accumulation, whereas litterbag methods used for knowing litterfall decompostion. Litterfall production at LOA one years old in planting is 2.27 ton ha-1 6 months-1 in planting line and 3.68 ton ha-1 6 months-1 in non- planting line. Litterfall production at LOA five years old is 4.97 ton ha-1 6 months-1 in planting line and 4.98 ton ha-1 6 months-1 in non-planting line. Litterfall production at LOA ten years old is 4.03 ton ha-1 6 months-1 in planting line and 4.67 ton ha-1 6 months-1 in non-planting line. LOA one year old plant at planting line in 1 ha for 6 months gave 920.6 kg carbon
