Abstract

The effect af  some treatments of  freshly cut Sumaura  pine logs (Pinus merkusii) on the rate of ambrosia  beetle attack  (Xylebarus sp.)  was observed. The results showed that:l . Most of the tested  logs were initially infested by the beetles about one week after felling.2.There was  no significant difference among the susceptibility of any sections of  the tree trumk,  whether they were teaken from  the bottom,  middle or top portions.3. Debarked logs were more  susceptible, at least in the first week. to the beetle attack.4. Keeping the logs in the shady areas. and  also sprinkling with water, may lengthen the period  of  Jog freshness, but it  also means praviding  suitable host  for  the beetles continuausly.

Abstract

This paper  reports  the studies  on sawmilling  woodworking properties  of 3 plantation  wood species.  derived from some plantation areas  in Java,  Logs of K.emiri  (Aleurites molluccana). tusam (Pinus merkusii) and Piaus oocarpa were sawn using a 44 inch bandsaw  to produce various size of boards. Following drying to approximately 1 5% of moisture content. the boardh were observed for their machining properties. The dried boards were processed further  into varaous end products and furnitures.Sawmilling trials shorwed that the average  sawn timber recoveries for  the respective species were 45%, 60% and 73%. regardless to the limited length and  width of  the resulted boards from  the sawmilling process, which were due  to the  small  log diameters,  a satisfactory  jointing  board can be  produced  through the application  of finger  and edge jointing machines.All  of  the species showed to have good  machining  properties and good  workability. Either  the fresh  logs or wood cants can beutilized for  producing  various  tuming products.  handicrafts  or even furnitures such as tables and chairs.  The  study  showed the potential utilization  of plantation  materials for various end products.

Abstract

This paper presents study results  of residual  stand damages caused by felling and  skidding activities.  The case study was  carried out at PT Dwi Marta in Riau in 1993.  The aims are : (1) tofind  the impact of felling and skidding on residual stand damages, (2) to know the factors  influencing the residual  stand  damages  and (3) tofind  the way of  reducing residual stand damage.Data on the number of trees with diameter 20 cm and up,   trees damages were collected.  The data  was analised  by  using themultiple regression.The result of study shows :1.The residuol stand damage caused by felling ranged between 2.7-10. 6% with an average of  6.6%/ha.2.The residual stand damage caused by skidding with crawler tractor  varied from  2. 7% to 22.3% with an average of 12. 7%ha.3.Both the number of  trees felled  and the  slope in had highly significant effect  to residual stand  damages. The greater  the  number of  trees felled  and  the slope, the greater the residual stand  damages.

Abstract

Riogas of 2-phase water hyacinth fermentation  and lamtoro wood of 4 years old were used as fuel for  cooking by the family.  The value of nutrition requirement was  10,353 calories  made of rice, meat,  fermented  soyabean,  etc. consumed by 5 persons in the family.The  study revealed that bio gas consumptian  was 1.281 1.  with the caloriffic  value of  4,569 Kcal/m3  and methane  content of 46.78%. This bio gas energy  was  5.85 Mcal for  181 minutes of cooking period.  This bio  gas consumption can be fulfilled  by using  33.14 kg fresh Water hyacinth per day in 300 1 volume reactor and 4.3% dry Water.Lamtoro  consumption  Was  4, 243 g for  159  minutes of cooking period with the  caloriffic  vatue of  4,299 Kca/kg and moisture  content of 14.50%. This lamtoro enetgy  was   18.24 Meal per day per family.  The total weight of wood cutting was   164. 80 kg with the moisture content ranged from  44. 74 to 63.33  %.  This  amount  will  be  enough for  cooking for  3 4 days  when converted  to 14.50 % maisture  content.

Abstract

Gross and anatomical  features  of  eleven lesser known  wood species of  Mimosaceae.  Myristicaceae and  Momceae  were  observed and  described  for  identification  pueposes.   Fiber  dimension were also  measured   and  evaluated  for  their  suitability  for  pulp manufacturing purposes.Members of Mimosaceae  (Adenanthera pavonina  and Albizia chinensis) are characterized  by homoselular  ray,  paratracheal  pa-renchyma and vestured pit. Further differenttiation  is posibie  based on other characters.Members  of  Myristicaceae (Myristica maxima and  Horsfieldia sylvestris) are characterized by apotracheal banded parenchyma. vessels  mostly in radial multiples and the presence of  taniniferous tube in ray  tissue.Further differentiation  is not possible.No spesific features  Were found  for  Moraups   but  two groups  were  recognized : 1)  those brown in colour  with paratrachealparenchyma and white deposit in some of  their  vessels (5 species) :  2) those white in  colaur, aportracheal  banded,  parenchyma,withoute white deposit in vessel (2 species).  Futher  differentiation of each group is possible up to genera  level.Ten out of eleven species examined contain fibers   with medium  quality. The rest one  species, (Prainea  limpato - Moraceae) contain  fibers with poor quality.

Abstract

The export tariff  policy on sawntimher is aimed at accelerating the development of  high volue-added  industry. Study on the valu- added of  teak processing industry belongs to the State  Forestry Company (Perum Perhutani)   is focused on  sawntimber. and  woodworking  products  such as doors, windows, frames, decking and parquets.Study  result shows  that  not  all sawmill plants provided positive value added.  in aggregate, sawntimber  industry yields  value  added  of  Rps. 55, 542  per cu. m or 11 percent of processed  raw   material value.  Wood working industry yielded a higher  value  added,  Rps.1,023, 791 per cu. m or almost  half  of  its  raw  material  value
