Produktivitas dan biaya penyaradaaan kayu dengan traktor pertanian type Ford 5660 di Hutan Tanaman Semaras, Pulau Laut
Investigation on assessing the productivity and cost of log-skidding using a farm tractor type Ford 5660 was carried out at the Semaras plantation forest under PT Inhutani's concession situated in Pulau Laut (South Kalimantan) in 1999. The objective was to get appropriate and reliable information on the productivity and cost of log-skidding. The data collected were skidding-distance, working time, log volumes, purchasing-cost, and labor wage, and further, they were all incorporated for assessment. The results were : 1) Log volumes skidded using the farm tractor ranged between 0.065 - 1.134 m cubic/ one trip with an average of 0.434 m cubic/one-trip, while skidding-distance varied from 0.25 - 1.85 hm with an average of 0.937 hm, 2) Skidding time was in the range of 0.06 - 1.14 hours/one-trip with an average of 0.23 hours/one-trip, 3). The productivity of log -skidding using the farm tractor recorded between 0.062 - 6.086 mcubic-hm/hour with an average of 2.075 m cubic-hm/hour, while the cost of log-skidding was in the range of Rp 9.522/m cubic-hm - Rp 931.000/m cubic-hm with average at Rp 55.777/m cubic, and 4). In implemanting the use of farm tractor for log-skidding, the log volume and skidding-distance are suggested at about 1.2 m cubic and 2 hm, serpectively.
