KELAS AWET 25 JENIS KAYU ANDALAN SETEMPAT TERHADAP RAYAP KAYU KERING DAN RAYAP TANAH

Abstract

Twenty five local reliable wood species were collected from forest areas in West Java for durability test. Wood samples measuring 5.0 cm length x 2.5 cm width x 2.0 cm thick were exposed to dry-wood termites (Cryptotermes cynocephalus Light.). Other samples measuring 2.0 cm length x 0.5 cm width x 0.5 cm thick were tested against subterranean termites (Coptotermes curvignathus Holmgreen.). Results revealed that out of the 25 investigated wood species 9 (36%) were classified as highly durable wood (i.e. classes I and II) to Cryptotermes cynocephalus Light. and the rest i.e. 16 species (64%) were classified at the lower durability performance (i.e. classes III, IV and V). The results also showed that only one out of 25 wood species (i.e. 4%) was categorized resistant against Coptotermes curvignathus Holmgreen., and the remaining 24 wood species (96%) were categorized in several durability classes (III, IV, and V). ABSTRAK Dua puluh lima jenis kayu andalan setempat yang berasal dari beberapa daerah di Jawa Barat diuji keawetannya. Kayu contoh uji yang berukuran 5,0 cm x 2,5 cm x 2,0 cm diuji terhadap rayap kayu kering (Cryptotermes cynocephalus Light.). Kayu contoh uji 2,0 cm x 0,5 cm x 0,5 cm diuji terhadap rayap tanah (Coptotermes curvignathus Holmgreen.). Hasil penelitian menunjukkan bahwa 9 jenis (36%) dari 25 jenis kayu yang diteliti masuk ke dalam kelas awet tinggi (kelas I dan II) terhadap Cryptotermes cynocephalus Light., dan sisanya yaitu 16 jenis (64%) masuk ke dalam kelas awet rendah (kelas III, IV dan V). Hasil penelitian terhadap terhadap Coptotermes curvignathus
