Abstract

This  investigation  is carried out  in the Central Kalimantan  and  West Kalimantan  areas at three logging companies. The purpose  of  this  investigation is to determine the  exploitation  factor  for  Gonystylus bancanus Miq.The  knowledge of  exploitation  factor will  help logging  companies in  the planning  and  control  of production. The exploitation  factor is the  ratio  of  stem volume utilized to the stem   volume that  actually  could  be utilized.   The latter represents  part  of  the stem  from  its lowest point  to its first  branch.  The part of stem  considered  utilized  is that part  which reached  the  log  pond   or  other  point   for  marketing.Exploitation  waste  in the areas of  the forest  companies  observed  ranges from  11.1%   to 21.2%.  This means  that  the exploitation  factor  ranges from 78.8%  to  88.9%.  The  average of  exploitation  waste  is 16.7%,  consisting  of parts  from stumps  2.9% and parts  from  stems  13.8%, and  hence  the  exploitation factor is 0.81.Exploitation  waste  can be kept  at a  minimum  by  better  planning  and  improving  skills  of  the  workers. The  exploitation  factors  among provincial  regions and logging companies  are not significantly.  Among  diameter  class, however,  they  differ highly significantly.  Therefore,  the exploitation factor reported here  should be used with great care.

Abstract

The study was carried out in three locations  in Jambi, Central Kalimantan and East Kalimantan. The number of forest companies observed  in each location  varies  from 2 to 4 which  were randomly  selected.The study  concludes that  :The  logging waste  ranges from 16,3 %  to 24,6 % of the clear bole volume. The average logging waste is 22,2  % consists of 12,2 %  trimming waste and stumps, and 9 % defects.The  exploitation  factor  ranges from 75,4 % to 83,7 % and  the average is 0,80.  This value  was previously  used for the observed  locations.Diameter class has a highly significant effect (P<0,01) on exploitation  factor.  The  exploitation  factor proportionally increases  with  the log diameters.

Abstract

A study on volume and classification of logging waste has been carried out in several forest companies in Aceh, North Sumatra, and East Kalimantan.  Average wood waste volume at the logged over areas having diameter range from  10 to 39  cm with one meter in length or more were measured using the Brereton method.The results of this investigation reveal that:I. Logging waste volume in Aceh range from 26,46  to 29,08  m3/ha  with an average of 27,85  m3/ha.  In North Sumatra the value ranges from 22,94  to 38,66  m3/ha  with an average of 28,90  m3/ha.  It  was formed  that in East Kalimantan  the logging waste ranges from22,00  to 81,94 m3/ha with an average of 52,38 m3/ha.2. The average wood waste at felling site was higher in the forest companies in East Kalimantan.3. Logging waste consists predominantly of those classified as 10 to 39 cm in diameter with 4 m length or more.4. The average volume of logging waste classifiedas 10 to 19 cm in diameter with 4 m length of more in Aceh, North Sumatra and East Kalimantan are consecutively 17,5 m3/ha,16,9 m3/ha and 24,9 m3/ha.

Abstract

The aim of the study is to estimate the volume of waste producted by forest  exploitation in the cutting area and toclassific of logging waste based on their source. The kind of logging waste based on their sources consist of : Waste come from there which to be cut and divided of bole (tunggak) remained stem (batang) becouse of bucking and stem up to the first branchDamage trees have been coused by influence of both cutting and yardingThe meaning of waste in the study in stem and branches with diameter up 10 cm and lenght up 1 m and length of bole do not depend on the size.  ·  Data analyisis used statistical method. The methode was analyisis of variance based on Bartlett test.Average of waste volume per ha is 18.935 m3ha consist of source of cutting trees  57.12 % effecting of cutting.38.13 % and effecting of yarding 4.16 %.In order to decrease waste and enhance resource efficiency, quickly make methode to solve problem with integratedsurvey between departments which connect with their problem forest companies and population sourounded area.
