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.

Most of the Indonesian wood species exhibit a wide differences in treatability. This may reduce effectiveness in loading several wood species simultaneously. This study investigated treatability of 41 wood species through full-cell process using CCB (copper-chrome-boron) preservatives.Representative wood samples, measuring 5 cm wide, 5 cm thick and I 00 cm long were preparedfrom each species and then remain to reach the air-dry condition. Pressures imposed during the process were consisted of initial and final vacuum al 500 mm Hg for 15 minutes, and a hydraulicpressure of 10 atmospheresfor 60 minutes.The results revealed that 20 of the study species were classified easy, I 2 species were moderate, 5 species were difficult, and the remaining 4 species were very difficult. Wood species within the class could be treated simultaneously. Results also indicated that there were great variations of chemical retention within the same class of penetration.

The result of dip diffusion treatment of ten wood species from lrian Jaya is reported in this paper. The wood species comprised among others wafut (Cananga odorata Hook.f. et Th.), starka (Octomeles sumatrana Miq.), senai (Dracontomelon mangiferum Bl.), sutiet (Spondias cytherea Sonn.), bemoe (Canarium indicum L.), raja (Pterygota forbesii F.v.Muell), sehiega (Celtis latifolia Planch.), sehiye (Sterculia macrophylla Vent.), susu (Alstonia scholaris R.Br.), and bimiek (Pterocymbium beccarii K. Schum.). Particular attention is directed to penetration and retention requirement/or wood uses under roof and outdoor without soil contact. Solution concentration of BFCA preservative used was 30 percent.Among ten wood species tested, only one species (sehye) could not be treated by dip diffusion process in 30 percent solution, because retention requirement for use under roof without soil contact (condition A) could not be reached. Two of the remaining nine wood species which could be treated by dip diffusion process and hence fulfilling the requirement for uses under condition B were raja and sehiega woods.Storage phase proposed for bemoe, raja and sehiega wood is 8 weeks, while for six other wood species ( wafut, stark a, senai, sutiet, susu and bimiek) is 4 weeks.During storage phase, severe attack of blue-stain on seven wood species were observed, while the remaining three species which were not affected were senai, sehiega and bimiek wood. An addition of anti blue-stain compound in the preservative is recommended

Pada saat ini, kayu dari dolok diameter kecil yang lebih rentan terhadap organisme perusak, merupakan pilihan tak terliindarkan untuk menggantikan kayu tua dari hutan alam yang mulai langka. Perbaikan sifat keawetan dengan memasukkan bahan kimia ke dalam kayu dapat meningkatkan daya tahan kayu dari serangan organisme perusak, Teknik memasukkan bahan kimia ke dalam kayu sangat menentukan keberhasilan dalam perbaikon sifat keawetannya. Penelitian dilakukan dengan tujuan untuk mengetahui pengaruh kadar air kayu mangium, konsentrasi larutan dan lama perendaman terhadap retensi dan penembusan senyawa boron. Hasilnya menunjukkan bahwa kadar air kayu tidak berpengaruh nyata terhadap retensi dan penembusan boron. Sebaliknya konsentrasi larutan berpengaruh sangat nyata terhadap retensi dan penembusan boron. Lama rendaman dingin berpengaruh sangat nyata terhadap retensi, tetapi terhadap penembusan tidak berpengaruh nyata. Untuk mendapatkan hasil yang baik, disarankan bahwa kayu mangium yang akan dipakai di bawah atap tanpa berhubungan dengan tanah yang diawetkan menggunakan metode rendaman dingin dengan larutan boron 10%, diperlukan waktu rendaman paling sedikit lima hari.

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.
