Produktivitas pengeluaran dolok kayu tusam dengan sistem kabel layang IWAFUJI 115

This report deals with assessing the performance of tusam (Pinus merkusii Jungh et de Vries) log removal using particular skyline system. The assessment in this regard is pointed out by the aim of this study, i.e. observing the productivity and operation cost of such removal. Related with those cases, investigaation has been conducted and located in Cikajang Sub Forestry District, Garut Forest District, under the Indonesian State Forest Interprise in West Java. The topographical locaaation has a slope aat about 5 degrees - 50 degrees with altitude ranging around 900 - 1000 m above sea level. The skyline machine used was a yarder manufactured in Japan with the brand name as 'IWAFUJI' and engine power at 115harvesting or removal of tusam log was done using a clear-cutting system. The result revealed that the removal productivity varied from 25.07 to 43.17 m cubic hm per hour with average at 33.33 m cubic hm per hour. Meanwhile, the corresponding production cost was Rp. 16.879.3 per m cubic. It turned out that such productivity (Y) was significantly affected by real removal frequency (X), which further could be expressed in regression equation Y= 1.0659 + 0.1245 X (r=0.5852) greater than F-table = 2.1). The opening soil was 5 percent.
