Investigation about the cold-soaking treatment has been conducted on five wood species (i.e. keruing, nyatoh, melur, pulai and meranti merah) for housing purposes. The penetrating preservative for this case was CCB (copper-chrome-boron) chemicals. Before being treated. the wood specimens measuring 3 - 5 cm (in length) by 3 - 5 cm (in width) were prepared from each of the five species. Such specimens could not be treated by implementing the conventionally prescribed treating schedule. because the measurement of preservative retention at such schedule should follow the revised standard/schedule which differed from the conventional one. Hence, in cold-soaking treatment using CCB preservative, the specimens of wood species for such purpose had to be modified in their sizes/shapes.Three different sizes/shapes were prepared, i.e. beam, truss, and rafters; and then were allowed to reach their air-dry moisture contents. Afterwards. they underwent cold-soaking treatment using CCB preservative in two different concentrations (i.e. 5 percent and 10 percent). Meanwhile. the soaking durations implemented for each concentration were consecutively 3,5 and 7 days.The results revealed that all the wood species in all three sizes/shapes (i.e. beam. truss. and rafters)could be treated using the revised schedule. Except for meranti in truss and rafter. Related as such. the revised treating schedule for these five species has been appropriately devised.

Three Wood species, i.e. tusam (Pinus merkusii Junh. et De Vr.), karet (Hevea brasiliensis Muell. Arg.) and jeungjing paraserianthes falcataria (L.) Nielsen) were treated with two bor preservatives using cold soaking method. The two preservatives used were borax at 5 % level and the mixture of borax and boric acid at 10 % level. The soaking periods were 1, 3, 5 and 7 days. Forty samples of the size 5 x 5 x 50 cm were used for each species and each treatment in thisn experiment. The avemge moisture content of the samples for each species were 29 .9 %, 31. 9% and 30.3% respectively.The results showed that two species, i.e. tusam and karet achieved the minimum standard on preservative retention and pentatiue. The required minimum retention for borex preservative is 8. 7 kg/m3, whereas for the mixture of borax and boric acid is 8.4 kg/m3. The required minimum penetration for both preservatives is 10 mm.The .study recommended that tusam should be treated in 5 days using borax preservative or 1 day using the mixture of borax and boric, both with cold soaking method. The treatment for karet was recommended to use the mixture of borax and boric acid within 3 days.

Moulding products made of two wood species in the form of coves were treated with BFCA preservative by cold soaking. The length of the test pieces were 30 cm. The duration of cold soaking treatment were 2, 4, 6 and 8 days, with preservative concentrations of 5 and 10 percent. The test results, after taking both retention and penetration requirements into consideration for wood uses under roof and in the open air without ground contact, showed that both wood species could be satisfactorily treated under experimental conditions. The treatment schedules proposed for both species are also presented in this paper. The average swelling of those species after treatment comparing to dimension are relatively small, therefore could be avaidable and has no affect on their use.

Fifteen wood species from Irian Jaya with sample test pieces measuring 5 x 5 x 60 cm, and water content from 20. 0-21.4 percent, were subjected to cold soaking treatment, using 5 and 10 percent concentration of BFCA preservative, for three, five and seven days. Taking into account the penetration and retention requirement for wood use condition under roof and outdoor, without ground contact, the result indicates that matoa wood could not be treated with the schedule proposed in this paper. The other fourteen wood species could be treated with any of the treatment schedule (Table 4). However, two species (honggimako and senai) meet only the requirement for use under roof without ground contact.

Twenty wood species obtained from Irion Joya measuring 5 x 5 x 60 cm were treated by hot and cold soaking using BFCA preservative with 5 and 10 percent of solution concentration. Hot immersion period was kept for 1 hour, 2 hours and 3 hours, with temperature range of 60°C-70°C, followed by cold immersion for 24 hours.The test result of the twenty wood species, after taking both penetration and retention requirements into consideration for wood uses under roof, and in the open air both without soil contact, showed that two wood species among them i.e. nifoek (Eucalyptus deglupta Bl.) and seriega (Eugenia sp.), could not be satisfactorily treated under the experimental conditions. The other eighteen species could be treated by either one, several, or all treating schedules employed in this research. Nevertheless, it is important to note that two of the eighteen species, i.e. sougwa (Palaquium multiflorum) and matoa (Pometia pinna ta Forst.) fulfilled the requirements for wood usage under the roof only without soil contact. The preservation schedule proposed for the eighteen wood species is presented in Table 4.
