摘要

This study was carried out to investigate the operational time and productivity of logging operation by chain saw, yarder attached on tractor, tower-yarder, mini-truck, mini-forwarder, and chipping operations by mini-chipper, large-chipper in order todevelop the efficient logging operation system for utilization of forest-biomass. As a result, the average felling and bucking time using chain saw at the site 1 and 2 was observed to be 182.7 sec/cycle and 518.5 sec/cycle respectively. The average yarding time was 202.5 sec/cycle using yarder attached on tractor and 295.1 sec/cycle using tower-yarder. The average forwarding time was 2,073 sec/ cycle using mini-truck and 2,248.4 sec/cycle using mini-forwarder. The operational time of felling and bucking using chain-saw can be delayed according to the direction of fallen trees. The selection of felling direction is very important to yarding operation because the direction between width-yarding and felling are interrelated. Productivity can be improvedthrough educating and training operators in the yarding operations. Mini-forwarder is needed to use because of higher productivity and lower cost than mini-truck. The operational productivity of felling and bucking by chain saw was 66.96 mVman day and 43.86 mVman day at site 1 and 2 respectively. The yarding productivity was 5.68 mVman,day by yarder attached on tractor, 10.74 mVman day by tower-yarder. The forwarding productivity was 21.29 mVman-day by mini-truck, 28.57 mVman-day by mini-forwarder. Thechipping productivity was 4.42 mVman- day by mini-chipper, 21.87 mVman-day by large-chipper.
