Preservation of Teak Sapwood by Cold Soaking Using Boron Against Drywood Termite (Cryptotermes cynocephalus Light.) Attacks.
The utilization of younger teakwood has a disadvantage, which is the sapwood is more susceptible to dry wood termites as it has less natural durability. Boric acid and borax are inexpensive preservatives, which contain boron as the active material. Those preservatives are also easy to be obtained as...

| description | The utilization of younger teakwood has a disadvantage, which is the sapwood is more susceptible to dry wood termites as it has less natural durability. Boric acid and borax are inexpensive preservatives, which contain boron as the active material. Those preservatives are also easy to be obtained as well as do not produce smells and the wood discoloration. The experiment materials were the sapwood parts from teak boards obtained from the felled trees in the community forest of Kali Bawang, Kulon Progo. A complete randomized block design was arranged in a factorial with two factors, which were the type of preservatives (boric acid and borax in 5% concentration) and duration of cold soaking (12, 24, 36, and 48 hours). To examine the durability of sample, dry wood termites (Cryptotermes cynocephalus Light) were used. The results showed that the average values of absorption, retention, and depth of penetration were 33.09 to 70.77 kg/m3, 3.81 to 10.77 kg/m3, and 2.34 to 3.86 mm, respectively. The average values of termite mortality during 2 weeks and 4 weeks were 46.33 to 53 %, 82.67 to 94.33 %. Weight reduction and degree of the damage were, 560 to 570 mg, and 30.34 to 31.27 %, respectively. By analysis of variance, there was an interaction between the type of preservatives and the duration of cold soaking factors, which affected significantly the termite mortality. Type of preservative affected significantly the absorption and penetration. Further, the duration of cold soaking affected significantly the level of absorption, retention and penetration. The application of preservatives could reduce the mass loss of specimens until 70 % as well as to give higher levels of mortality rate (87-92 %) compared to that of untreated one. |
