BEBERAPA ASPEK PENGELUARAN KAYU DARI AREAL KONVERSI UNTUK BAHAN BAKU INDUSTRI DI SUMATERASELATAN

Abstract

Conversion forests in Indonesia whida are pardy still virgin account for about 41.2 % of the total forest areas. The conversion is needed because of the exlensification of  land for fanning, transmigration, and the exlension of urban area. Pre.senJly, the  information on wood polential from   this forest is scanty. This information is needed to know the possible Ulilization of the logs.

The aim of this study is to asses logs potential, and their possible uses for industrial raw malerial and cost analysis.  The study was conducted in two forest concession area in South Sumalra Province, in March 1991.

The  result of this study reveals that  the logs potential   in  the conversion  forests are relatively high, especialy of lop  wiJh diameler  50 cm and up. It contribults about 60.79 % and 86.99% (from  forest concession area I and II) from all logs with diamder  2() Can and up. The dominant tree species found in location are meranti (Shorea  sp.), balau (Shorea  spp., Hopea spp.), ramin (Gonystylus bancanus Kurz.), kempas  (Koompasia malaccensis  Maing), jelutung (Dyera  spp.) and pulai (Alstonia  spp.).

The main uses of this wood is for the company own industry uses (57.53%) followed by free sale (28.17 %), and sale to other industry (14.30 %). Logs extraction incurred cost about Rp.  14 450,- until Rp.  16.  700,- per  cu.m  for forlling, skidding aclivilies and transporting logs to industrial sue.

The cost differences depend on wood species, the distances  and risk factor. The proportion  of this cost is about  19.66 % until 22. 72 % of log price.
