Abstract

This paper deals with reseach results on bamboo preservation using boucherie method. Two bamboo species,  namely andong (Gigantocloa verticillta Munro) and tali  (Gigantochloa apus Kurtz) were treated freshly using Borax (Na2B4O7. IOH2O)  solution with strenght solution of 5% as preservative. One of butt of the 8 length bamboo was immersed 10 cm in borax solution for 2. 4. 6, 8.  and  10  days and  the penetration of preservative were observed. The results showed  that  the  penetration  of  preservative  in  andong  bamboo for 2. 5, 6,  8,  and 10 consecutively  were 131,40 cm, 304,92 cm, 308.42 cm, 469,88  and 315,28 cm, while  in tali, bamboo  were 68,30 cm,  116.83   cm, 141,88 cm  and 128,17 cm,  respectively.  Maximum pnetration of preservative was achived in 8 days immersion for andong and 6 days tali.

Abstract

The penetration of wood preservative of ten wood species from Lampung was studied. The observation was conducted after the timber had been preserved by diffusion method. The BFCA 30% and wood samples of 6 cm by 10 cm by 200 cm were used in this experiment. The results showed that wood species has significant effect on penetration, while duration of diffusion storage period has the same effect only on keruing, damar asam, balam and cengal banglai. Eight weeks of storage was better than 4 weeks on those timber, but not for the other species. According to IUFRO classification, pulai kayu tabu and bintangur can be classified as permeable, while the others were classified as moderate.

Abstract

The utiliization of wood for cooling tower in Indonesia tends to increase and has become more important. Wood as material for cooling tower has been applied commercially in several developed countries such as New Zealand,USA and Japan. While in indonesia it has just been started in 1981 after the establishment of Kamojang Geothermal Power Station Unit 1. This paper deals with some experience in treating keruing wood (Dipterocarpus spp.) as material for cooling tower by vacuum-pressure impregnation. The result shows that keruing is easy to treat. In other to meet the retention of 24 kg/m3, the concentration of the solution must be at least 6.25 percent and absortion of 384 liters of preservative per cu.m.

Abstract

This paper  deals with  a study  on a momentary  dipping  of freshly  sawn wood  for short periods  in a solution  of  33% boric  acid equivalent (BAE)  and  33% BFCA  preservative  at ambient   temperature,   followed by  one,  two,  three  and  four weeks  of  diffusion storage.  Boron  penetration were  then  calculated  and analyzed.  Results  of the study  reveal that  timber species  and  preservatives   do  not  any  significant   effect,   but  diffusion periods   show  highly  significant   effect to  boron penetration.   Boron  penetration   seemed  is normally   with  the  increas in diffusion storage period. Diffusion  storage of four weeks  for  all timber   tested  in  this  experiment  shows  relatively  good  results, so that  diffusion storage periods  for  four weeks  may  be recommended.

Abstract

Wood preservative penetration and retention on five wood species using hot and cold bath process was studied. Wood samples measuring 5 cm x 5 cm x 60 cm were immersed in BFCA preservative solution under temperature of 70° C for nil (control), one, two and three hours then cooled for a day.The result indicates that red meranti (Shorea platycados V.Sl .) is more permeable compared with other species (bangkirai, bungur, damar laut and kapur). In red meranti, one hour immersion in hot preservative yields penetration which conforms with the SKI C-bo-008 Standard for wood building, whereas in other 4 species, the treatment does not seem to be more superior. compared with cold immersion method.

Abstract

The  degree  of  protection  offerd   by a wood  preservative  depends  upon  the  quality  of preservative retained by the timber, the depth penetration, and  the permanence of  preservative   in  the wood.On  the hot and  cold  bath process,  the  timber is immersed in cold preservative  and  the  bath and timber are heated up together to around 70°C for one, two, three hours until  the timber  is hot  throught,  and  the whole  then allowed to cool down for 24  hours.For  all  timber species tested   in  this  experiment   the  depth   of  penetration  and  retention    of  preservative  was measured  after  treatment.  The  result  of  which  can be seen in Table 1.  After  calculated  and analysis (Table 2 and Table  3) the following conclusions  could  be draw :Timber species  has highly  significant  on  boron penetration  and retention.  Boron penetration   a seemed  to  be generally getting  deeper  with  increased   hot  soaking  hours; but one hour  is fully.Generally  speaking, hot  and cold  bath process  are  to  be preferred  although   with  mahoni  (Swietenia  mahogani  Jack:) and  tanjung  (Mimmusops  elengi   L.)  timbers  the preservative   retention less than  the  other  timbers.

Abstract

A study on the treatability of eleven wood species was carried out using hot and cold soaking  treatment  methods  with Koppers Formula  7 as preservative. Specimens measuring 50 cm x 5 cm x 5 cm were soaked  in five  and ten percent preservative  solution for  a duration  of one, two, and three hours and then allowed to cool while the timber is still soaked in the liquid.  The penetration  and retention  were recorded. From this study  the following   conclusions  could  be drawn:The treatment schedule and concentration  of solution  have a highly significant  effect  on the preservative  penetration  and retention. Much higher retention  was shown  when longer hot soaking  and higher concentration  were employed.

Abstract

Impregnation    under  pressure  is  the  most  effective  way  of  applying  preservative   to  timbers,   but  not  all species can be treated  effectively  using  the  method.   Air-dried  timbers  of  5 cm  x  5 cm x  100 cm in dimension   were impregnated   with preservative   used  for  constructional   purposes.   Part of  wood  samples  was presteamed.   Prior to  the preservative   treatment both  groups  were reconditioned    to  the same  moisture  content   as the  reference   material  (air dried).Retention  and  penetration   figures  have  increased as presteaming   was applied.   The  result revealed  that  two  timbers preserved   met   the  standard   requirement.    The  preservation   schedule  proposed   for  the  timbers  is presented   in this paper.

Abstract

Most of Indonesian wood species are classified as less durable, so preservation is needed. Wood preservation inIndonesiamainly depends on imported preservatives. The preservatives are not only toxic to wood destroying organism but also to humans and the environments. Therefore alternative to treat wood should be sought and developed in term of the preservatives used as well as the methods. One that can be proposed is treating wood at high temperature combine with environmentally friendly preservatives, as tried in this experiment.The wood species used in this experiment were rubber wood (Hevea brasilliensis) and pine (Pinus merkusii). Both woods were treated with borax at two concentrations (3% and 5%) by cold-soaking method for 24 hours. The treated woods were subsequently air dried. Then those woods were treated at three levels of high temperature (180ºC, 200ºC, and 220ºC) in an oven for one hour. Finally, the treated wood samples were laboratory-tested by assessing their resistance to dry wood termites (Cryptotermes synocephalus Light.) and powder-post beetles (Heterobostrychus aequalis Wat).The results revealed that increases of heating temperature and concentration of preservatives resulted in more durable woods. In this regard their resistance to dry wood termite and powder-post beetles was increased as shown by smaller weight loss. Treating wood at temperature of 180ºC combined with borax at concentration of 3% resulted in 100% termite mortality on rubber wood and pine.
