BIOMASA DAN KANDUNGAN KARBON PADA HUTAN TANAMAN TUSAM (Pinus merkusii Jungh et de Vriese) UMUR LIMA TAHUN DI CIANTEN, BOGOR, JAWA BARAT

Abstract

This study was designed to formulate pine allometric equations and estimate biomass production and carbon stock. Data collection was done in Resort Pemangkuan Hutan (RPH) Cianten, BKPH Leuwiliang, KPH Bogor, Perum Perhutani Unit III, West Java, from March to April 2005. This research employed destructive sampling method covering 23 representative trees (spacing 2 m x 3 m) located on 16 plots. Size of each plot was 20 m x 30 m. Results obtained from this research indicated that average oven dry matter of plant organ consisting stem, branch and twig, leaves, and roots were 6.04 kg, 3.15 kg, 3.36 kg, and 1.78 kg respectively per plant at age of 5 years. The allometric equation expressing the relationship between above ground biomass and Dbh was Y = 0.17689 X2.0501 (R2 = 0.9464), relationship between stem and Dbh was Y = 0.11467 X1.9238 (R2 = 0.9635), relationship between roots and Dbh was Y = 0.020346 X2.1291 (R2 = 0.9163), and relationship between total biomass and Dbh was Y = 0.19687X2.0611 (R2 = 0.9472). The estimation results indicatds that the highest carbon stock originated from plant partition was produced from stem part (5.03 ton/ha), followed by leaves (2.8 ton/ha), branch and twig (2.62 ton/ha), and roots (1.48 ton/ha). The total carbon stock yield from 5 year old pine plantation was 11.93 to C/ha (equivalent to 43.74 ton CO2/ha)
