Judul: Ketahanan Kayu Jati Unggul Nasional (Tectona grandis Lf.) Terhadap Serangan Rayap Tanah dan Rayap Kayu Kering
Abstrak: Fast grown’s teak has low durability because the teak was harvested in short age. The aims of study was to study effect combination of temperature and heat periode to teak wood durability againts subterranean (Coptotermes curvignathus Holmgren) and dry wood termites (Cryptotermes cynocephalus Light). The temperature level used in this study were 1000C, 1200C, 1400C, 1600C, and 1800C and heating periode level used were 3 hours, 6 hours, 9 hours, 12 hours, dan 24 hours. The wood samples were tested by termites attack according to SNI 01-7207-2006. Result showed that in subterranean termites test, heating periode affected to weight loss. Increasing periode of heating, increase durabiliti’s teak wood from class IV to class III. While, in dry wood termites test, wood durablity was affected by temperature and heating at 160-1800C increase durabiliti’s teak wood from class IV to class III.

Abstrak: The objective of this research was to analyze the natural durability of 12 woods species grown in Mount Walat Forest Education, Bogor Agricultural University against subterranean termite (Coptotermes curvignathus Holmgren) and dry wood termite (Cryptotermes cynocephalus Light). Sapwood and heartwood parts of bungur, jabon, puspa, simpur, tanjung, agathis, mahoni, pasang, sungkai, krey payung, and salam with diameter in the range of 15-35 cm were used in this experiment. Assessment of natural durability of wood against termite attacked referred to SNI 01.7207-2006. The results indicated that the weight losses of woods were varied among species and wood part. Sap and heartwoods of filicium, sapwood of bungur, pasang, and heartwood of simpur, and mahoni had the highest natural durability against C. curvignathus (2nd class). Sap and heartwood of salam, heartwood of bungur, puspa, tanjung were classified to 3rd class. Sap and heartwood of pinus, sungkai, sapwood of simpur, mahoni, puspa, tanjung and heartwood of pasang were classified to 4th class. Sap and heartwood of agathis, jabon, and pinus had the lowest natural durability against C. curvignathus (5th class). Almost all parts of 12 woods species tested belonged to 1st class against C cynocephalus except sapwood of agathis, pinus, and jabon belonged to 2nd class

Judul: Infeksin virus rota pada anak babi
Abstrak: Virus Rota sudah lama diduga sebagai salah satu penyebab diare pada anak babi yang baru dilahirkan. Hal ini diperkuat dengan berhasilnya Mebus dan kawan-kawan mengidentifikasi virus Rota pada kejadian diare yang ter jadi pada anak sapi yang baru dilahirkan. Infeksi virus Rota merupakan hal yang serius, kejadian yang mewabah pernah dilaporkan di Amerika Serikat, Inggris, Kanada dan Australia. Sedangkan kejadian di Indonesia yang dihubungkan dengan infeksi virus Rota belum dilaporkan. Virus Rota termasuk keluarga Reo viridea. Sesuai dengan namanya, virus Rota menyerupai roda (Rota = Wheel), mengandung asam nukleat (nucleid acid) yang berupa asam nukleat ribo (ribo nucleid acid, RNA) dan berserabut ganda (double stranded), tidak mempunyai selubung (envelop atau peplos). Hewan rentan adalah hewan yang berumur sangat muda. Selain menyerang babi, dapat pula menyerang sapi, domba, rusa, anjing, kucing, tikus, kelinci, unggas dan manusia. ...
