Judul: Kualitas Pertumbuhan dan Karakteristik Kayu Meranti Merah (Shorea leprosula Miq.) hasil budidaya
Abstrak: In order to assure the quality Red Meranti especially S. leprosula wood from plantation similar to that from natural grown, their basic properties were studied. Result shows that quality of Red Meranti wood studied was similar to that of naturally grown, except for its fibers which were shorter and thinner than those of naturally grown. It found that only specific gravity (SG) of wood was not influenced by stem diameter, and only wood moisture was influenced by growth ring. Result also shows that average values of fiber length, cell wall thickness, moisture content, wood density and SG are 968.12 μm, 2.72 μm, 91.52%, 0.76 g/cm3 and 0.50, respectively. The wood is categorized as strength class of III, therefore, this S. leprosula wood is potential as raw material for plywood and furniture manufacturing, as well as for the 3-rd class of structural and other purposes. The wood is not suitable for the highest quality of pulp and paper manufacturing.

Judul: Pengaruh Penjarangan dan Pelebaran Jarak Naungan terhadap Sifat Dasar Kayu Meranti Merah
Abstrak: Endeavor to increase the growth rate of red meranti (Shorea leprosula Miq.) in natural forest has been carried out through the silviculture system of selective cutting and line planting (TPTJ). Even though high growth rate has been understood tend to decrease certain basic properties of wood; however measurement of the basic properties specifically done on the red meranti resulted from thinning and line planting treatment has been lacking. In the present research, measurement of the basic properties of red meranti resulted from thinning and line planting treatment was done. It was found that thinning and increasing line planting increased the diameter of tree, longitudinal shrinkage, fiber diameter, lumen diameter, sapwood extractives, and ash content. On the other hand, these treatment decreased heartwood proportion, crown coverage, specific gravity, wood density, radial and tangential shrinkage, fiber length, cell wall thickness and heartwood extractives. Lignin, holocellulose, -cellulose and hemicelluloses were not significantly influenced by the treatments.

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.
