Judul: Keawetan Alami Dua Belas Jenis Kayu dari Hutan Pendidikan Gunung Walat terhadap Serangan Rayap
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: Wood Decomposers in Six Community Wood Species at Two Locations
Abstrak: Kayu memiliki hubungan erat dengan rayap dan jamur sebagai dekomposer. Penelitian ini bertujuan menganalisis jumlah kayu terserang rayap dan jamur pada enam jenis kayu rakyat selama enam bulan pengujian pada dua lokasi berbeda, menganalisis tingkat kerusakannya, serta mengidentifikasi spesies rayap dan jamur yang menyerangnya. Penelitian dilakukan pada dua lokasi, yaitu Arboretum Fakultas Kehutanan dan Lingkunan IPB serta permukiman di Bogor Asri, Kecamatan Cibinong, Kabupaten Bogor. Kayu yang diuji adalah Acacia mangium, Falcataria moluccana, Anthocephalus cadamba, Maesopsis eminii, Pinus merkusii, dan Hevea brasiliensis. Pengujian dilakukan berdasarkan ASTM D 1758-06. Jumlah kayu terserang meningkat seiring dengan lama waktu pengujian dan serangannya di arboretum (75%) lebih tinggi dibanding di permukiman (39,4%). Tingkat kerusakan kayu tertinggi di arboretum adalah kayu karet (35,4 g) sedangkan di permukiman adalah kayu pinus (18,9 g). Jenis rayap tanah yang ditemukan adalah Macrotermes sp., Microtermes sp., Schedorhinotermes sp., dan Odontotermes sp. Jenis jamur pelapuk yang ditemukan adalah Aspergillus sp., Mucor sp., Trichoderma sp., Gliocladium sp., Mycelia sterilia, dan cendawan merah., Wood has a close relationship with termites and fungi as decomposers. This study aims to analyze the frequency of termite and fungal attacks on six community wood species during six months testing period at two different locations, to analyze the intensity of wood damage, and to identify the species of termites and fungi that attack them. The research was conducted at two locations, namely the Arboretum of the Faculty of Forestry and Environment of IPB and the settlement area in Bogor Asri, Cibinong District, Bogor Regency. The woods tested were Acacia mangium, Falcataria moluccana, Anthocephalus cadamba, Maesopsis eminii, Pinus merkusii, and Hevea brasiliensis. The tests were carried out according to ASTM D 1758-06. The frequency of attacks increased with the length of time of testing and the attacks were higher in arboretum (75%) than in settlement (39,4%). The highest intensity of wood damage in the arboretum was rubber wood (35,4 g); in settlements, it was pine wood (18,9 g). The subterranean termites found were Macrotermes sp., Microtermes sp., Schedorhinotermes sp., and Odontotermes sp. The rot fungi found were Aspergillus sp., Mucor sp., Trichoderma sp., Gliocladium sp., Mycelia sterilia, and red fungi.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
