Abstract

This study examined cost and productivity of tree length logging system in natural production forest. The study was conducted in several forest concession in Kalimantan. The results showed that the sytem is capable to extract the clearbole part as main production log and the wasted log above the first branch into the landing point. Skidding productivityof tree length syistem in PT Gunung Gajah Abadi 6,25 m³/jam/hm, PT Narkata Rimba 15,54 m /br/bm, PT Balikpapan Forest Industries 16,67 m³/br/bm, PT Jatitrin Co Ltd 20,76 m³ /br/hm, PT Dwima Jaya Utama 36,69 m³/hr/bm dan PT Kayu Tribuana Rama 21,67 m³/hr/bm. The average cost of tree length logging system in PT Gunung Gajab Abadi is Rp 84.817,92/m³, PT Narkata Rimba Rp 33.636,55/ m', PT Balikpapan Forest Industries Rp 31,800,34/m³, PT Jatitrin Co Ltd Rp. 25.535,26/ m³, PT Dmimajaya Utama Rp 14.155,19/ m³ and PT Kayn Tribuana Rama Rp. 25.207,41/m³.

Abstract

Productive and effective logging activities are usually contentrated at the felling site. These mean that an ideas, felling site development at peat swamp forest plantation in determined by an optimum area. There has been limited study on optimum felling site area at peat swamp forest plantation in Indonesia. This study was carried out in June 2011 at concession area of Arara Abadi Company, Riau. This study aimed of finding out optimum felling site area at peat swamp forest plantation. Field data from some alternatives felling site area i.e. productivity and cost of skidding and canal maintenance/development were collected and processed by tabulation. Study result revealed that based on technique and cost aspects felling site of 150 m x 350 m is an optimum size.
