Abstract

Rubberwood  is  becoming more important in  Indonesia and  hence research for   better treatment of  this  very susceptible wood  species  is badly needed. In general, the impregnation  of  the green wood  results in a limited  penetration.Boiling before preservative treatment by alternating pressure process greatly  improved  the  treatment of rubberwood. A boiling period  for one hour was sufficient to obtain  required penetration  of preservative.

Abstract

An  investigation on the effectiveness of forest  roads was conducted at PT  Siak  Raya  Timber in Riau in 1989.  The objective is to find  out  the  information on construction and  uses of forest roads. The length of main and  branch roads and target and actual productions   during the latest six years (from1983/1984  to 198811989)  were collected.  The investigation  results reveal that: 1.The  length  of  forest   roads  built  annually   by  PT  Siak  Raya  Timber  ranged from  16  km  (consisting  of  10 km  main and  6 km branch  roads)  to 85 km  (consisting  of 65 km  main and 20 km branch roads), with an average of 21.66 km (consisting of 11.68 km  main and 20 km branch roads). 2.The annual  felling area of PT Siak Raya Timber was 2,600 ha. The road densities  ranged from  6.16 m/ha  to 32.69  m/ha with  an  average of 21.66 m/ha. The road density is some what high compared  to that stated  in the Forest Agreement. 3.The actual production of  logs at PT Siak Raya Timber ranged from  21,225.65 m3/year  to 47,199.04 m3/year  with an average of 34,417.03 m3/year. 4.The  differencf  between target and actual production averages was relatively large i.e.  75,500 m3/year compared to 34,417.03 m3/year. The effectiveness of forest roads  ranged  from 268.67m3/km-year to 2,305.86 m3/km-year with  an average of 1,010 m3/km-year.

Abstract

The result of  a study on briqueting charcoal from activated charcoal residue,  prepared  by using the hydraulic  press process is presented  in this paper. The residue :  was subjected to two different treatments, namely unwashed  and  washed with  water.  Following   the  treatment, each residue  material  was mixed  with  starch adhesive, using four different concentrations:  0 percent, 1 percent, 2 percent  and 3 percent,  consecutively.The  respons  evaluated from the  briquetted charcoal are the  moisture content, ash content, volatile matter, fixed carbon, density, crushing strength and calorific value. The result shows  that  moisture  content ranges from  3,36 - 5,56 percent, ash content  from  8,06  - 12,78 percent, volatile matter from  23,56 - 41,28 percent, fixed carbon from  45,9 - 68,38  percent, density from 0,6471-0,7985 gr/cm, crushing strength from 0,79 - 6,33 kg/cm and  the  calorific values ranged from 5243,25  -  6378,84  cal/gr.

Abstract

The results  of  laboratory test of wood wool board properties made from 6 individual  wood  species obtained from East  Kalimantan, Jambi, South Sumatera and Maluku  province   are reported  in  this paper. The properties tested were board density, moisture content,   thickness  reduction  due to compression  and bending strength.The study   reveals that  average yield  of  wood  wool  is  348  kg per  cubic  meter  of log input. The wood  wool of Acacia mangium must be soaked  in  cold  water  for  24  hours  prior to  manufacturing  of  wood  wool  board, whereas  the other species can be processed  directly.The  physical and  mechanical  properties of  wood  wool  boards  made  from  three  wood  species (Shorea platyclados, Acacia mangium and Shorea leprosulaf) catalyzed with  CaCl2 solution were in conformity with  the DIN 1101  standard Nevertheless, only two  species  (S. platyclados and A. mangium) catalyzed with Ca(OH)2 suspension met the  standard requirement.

Abstract

Sapstain fungi are the common fungi attacking fresh cut rattan which cause serious  economic deterioration.  The pattern of  sapstain  infestation on  fresh cut rattan and its prevention  were   studied in  rattan  processing industries at Cirebon.The material used consisted of fresh cut rattan  of semambu (Calamus scipionum  Burr) and seel (Daemonorop sp), measuring 30 cm long. Five pesticides were tested on rattan for sapstain protection. The staining percentage was inspected fomightly for two  months, whereas  the pattern of  fungal attack was inspected weekly  for one month. The  data were completely randomised design analysed and  tested by Dunnet  procedure at level 1% and 5%. The degree of staining  defect was transformed  into  arcsin √%.The result showed that semambu and seel were susceptible to sapstain. The initial  infestation starts  when  the rattan is freshly cut,  indicating  by the staining on  the cutting  surface. The  fungi  mycelia penetrate through parenchym-cell and tenninate in the nodes.  The rate of penetration  fungi  mycelium  is approximately  6 cm per week.The TCMTB/MTC, Thiobendazol + IF 1000 and MBT pesticides were found  effective   to prevent sapstain on fresh cut rattan.

Abstract

Susceptibility of sungkai wood (Peronema canescens) to ambrosia  beetle infestations   was studied. Fresh cut sungkai poles, measuring about 20 cm in diameter and 75 cm in length, were selected  for the test. Six pole  treatments were chosen each of which was represented by five replications. The  test poles  were kept under shade near felling site.   Observations were respectively made for the  number  of  ambrosia  beetle tunnels  occuring  on  the pole  surface  after  3, 6, 9, 15, and 40 days. The  development pattern of the beetle  gallery system, based on  number  of  tunnel  showed  up  on some  peeling  off areas of some  consecutive  depth  of  the heaviest  infested  test pole,  was also observed.The  result shows that unbarked (with and without  flint kote) poles are practically   unattack by the borer. Poles treated with ethanol (flint-koted barked  and unbarked) were  not  attacked until  day  9. The  most  severe attack  occurs on  the  barked  poles  (with  or  without   flint kote) Although the  attack  practically  does not  seem to occur  until day 21. Regression equation Y =27,65 + 6,93X - 5,51X , where Y =number of tunnels found on each peeling  area and  X  = depth  of peeling  (cm), represents  the development   pattern  of  the beetle galleries within  the log.

Abstract

Forestry  sub-sector has an  important  contribution to economic development  of  West Kalimantan. For the last few years  the average  contribution  per  year  in  the  gross  domestic   regional  product, the  manpower  absorbtion, the social income  earning,  the  regional  income  earning, and the foreign exchange  earning of  the region is estimated  around 11.20%, 66.69%, 81.91%, 47.9 7%, and  58.79%, respectively. The contribution  elasticities  of the five  economic   variables mentioned are 0.83, 1.03, 1.06, 0.94, and  0.75,  respectively. For the next nine  years, the  contribution  will  be still possible  to raise the  economic growth of  the  region.  After   that  periode, however, it will not be the anymore without a substantial progress in development  of  both  the production forest  resource and the secondary  wood  industry.
