Litter Production of Logged-over Forest using Indonesia Selective Cutting System and Strip Planting (TPTJ) at PT. Sari Bumi Kusuma

Enrichment is a planting activity in logged-over areas with less natural regeneration of commercial species. Enrichment planting on Indonesian Silvicultural System of Selective Cutting and Strip Planting (TPTJ) aims to increase the productivity of logged-over areas (LOA) using Strip Plantation System. Strip Planting System is an intensive management system attempted by opening logged-over area for strip planting and planting purposed species. Plantation in Strip Plantation System needs much nutrition for its growth. Nutrition returning through litter on TPTJsystem was essentially notified. This research aims to identify litter production in strip planting and on-strip planting at logged-over areas, within one year, five years, ten years after logging, andprimary forest at PT. Sari BumiKusuma. This research was conducted from September 2010 to February 2011. The litter trap was used to calculate litter accumulation.Litter production at LOA after one year of planting is 2.27 ton.ha-1.6 months-1in strip planting and 3.68 ton.ha-1.6 months-1in non-strip planting; litter production at LOA after five years is 4.97 ton.ha-1.6 months-1in strip planting and 4.98 ton.ha-1.6 months-1in non-strip planting; while litter production at LOA after ten years is 4.03 ton.ha-1.6 months-1in strip planting and 4.67 ton.ha-1.6 months-1in non-strip planting. Using Selective Cutting and Strip Planting System (TPTJ), it is found that litter production in strip planting was not significantly different from that in non-strip planting, and that the litter production is recovered after 5 years.
