Five timber species were treated with Koppers Formula 7 using momentary immersion method. The samples (5 cm x 5 cm x 100 cm) were then introduced into a diffusion chamber for one, three, or jive weeks. The depth of penetration was measured after cutting the samples and result analyzed. The conclusions are :The duration of diffusion has a highly significant effect on preservative penetration, while the timber species did not have a significant bearing in the penetration. The rate of diffusion is proporsional to the treatment time.Taking the forgoing result into account, the moisture content has no effect on the depth of penetration.The momentary immersion method appeared to have met to the standar requirement for all timber species tested in this experiment.The result indicated that duration in one week gives statisfactory penetration for the mahoni, manii and jeungjing species. The durian and petai however, could only give statisfactory results when the duration is longer than three weeks

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.

This paper deals with an experiment of soaking treatment of two meranti wood species each with Wolmanit CB and Koppers Formula 7. In this process three groups of wood samples measure 50 cm x 5 cm x 5 cm were submerged in a bath of preservative for three, five and seven days. The treatability of the samples were studied. From this study the following conclusions could be drawn:Penetration of both preservatives could be increased into red meranti when high concentration were employed.Retention of Koppers Formula 7 increases on both meranti when high concentration was employed.In general the such treatment can not be recomended due to the result obtained is lower than the treatment spesification requirements for housing wood preservation.

Since CCA preservative was banned in Indonesia, alternative preservative should be searched. One of the preservative which has good fixation characteristic like CCA is ZFE. preservative that contain zink, fluor and chrom.The retention and penetration of ZFK in five Indonesian wood species were studied. The ZFK preservative was applied using soaking method for 3, 5 and 7 days, where the solution concentration applied was 5 % and 10%. Five wood species choosed in the experiment were damar (Agathis loranthifolia), keruing (Dipterocarpus caudiferus), jelutung (Dyera costulata), meranti merah (Shorea palembanica) and nyatoh (Palaquium leiocarpum).The lest results based on retention and penetration requirements for wood used under roof, and in the open air both without ground contact, showed that only two species, keruing and jelutung, could satisfactorily meet the standard under the experimental conditions, while other tree species (damar, meranti merah and nyatoh) do not comply with tire standard. For under roof and in the open air uses without ground contact keruing can be consecutively soaked for 7 days in Basilit ZFK solution of 10% , while jelutung for 5 days.

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.

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.

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.

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.

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.

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.
