| dc.description.abstract | Ten (10) tropical hardwoods with low natural durability were treated with CF, plasma. Plasma treatments were carried out in a plasma reactor with a I-meter length of rotary cylindrical glass with inner diameter of 10 cm. The plasma reactor was provided with an outside semi-cylindrical electrode of 10 watt, 13.56 MHz. 30- mT pressure, l50-mT pressure in the absence of plasma and 250-mT pressure in the presence of plasma. Plasma treatments were carried out for 10 mmutes. Plasma treated-wood samples of 0.3 cm x 2.5 cm x 2.5 cm size were then ted to Cryptotermes cynocephalus Light for 12 weeks under standard conditions. The mortality of termites and the weight loss of samples were measured in accordance with methods developed by Martawijaya (1989) and the degree of protection was determmed according to American Wood Preservers'Association (1972). | id |
