PENINGKATAN EFISIENSI PEMANFAATAN KAYU GMELINA (Gmelina arborea) MELALUI PENERAPAN TEKNIK PENEBANGAN DAN SIKAP TUBUH PADA DUA KELERENGAN DI PT. PURWA PERMAI, KALIMANTAN TENGAH
Abstract: Efficiency and
effectively of felling techniques and feller postures on a certain slopes can
ascertain a whole timber utilization efficiency. This study was carried out on
July 2007 in Central Kalimantan. The aim of the study is to find out the
effects of slopes (≤ 15% and > 15%),
feller postures (squatted, bowed, and stand), and felling techniques
(conventional/CLT and lowest possible felling techniques/LPFT) to increasing
TUE of gmelina. To recommend a better technique, the two felling techniques
have been compared based on productivity, efficiency and production cost by
using split plot factorial 2x2x3.The results showed that implementing LPFT can
increase TUE about 16.7% equal Rp 1,472,263,200/year and leaved a lowest stump height around 10.2 cm.
