Judul: Sifat Fisis dan Mekanis Kayu Tumih (Combretocarpus rotundatus (Miq.) Danser) Asal Kalimantan Tengah
Abstrak: Tumih wood (Combretocarpus rotundatus) is a lesser known species which usually grows in secondary forest or forest with an open canopy that is flooded with peat water and swamp peat in Central Kalimantan. The purpose of this research was to analyze physical properties and mechanical properties of tumih wood for appropriate processing and utilization. The results showed the average value of oven dry density and specific gravity of tumih wood were 0.99 g/cm3 and 0.70. Its fresh and air dry moisture content content were 63.51% and 18.64% respectively. The volume shrinkage from fresh conditions to air dry and oven dry conditions were 3.36% and 6.85%respectively. The tangential and radial shrinkage were 6.38% and 3.59% respectively. So the T/R shrinkage ratio was 1.86 which showed that this wood had good dimensional stability. Permeability of longitudinal was about 1.2 times and 1.4 times of radial and tangential permeability respectively. The mechanical test results of MOE, MOR, and hardness of tumih wood were 106 131.80 kg/cm2, 551.31 kg/cm2, and 119.45 kg/cm2 respectively. Based on this mechanical properties tumih wood was classified strength class III which is good to be used as sills, door panel, window, furniture, parquet flooring and rung .

Judul: Keawetan Alami Kayu Tumih (Combretocarpus rotundatus Miq Danser) dari Serangan Rayap Kayu Kering, Rayap Tanah dan Jamur Pelapuk Kayu
Abstrak: Combretocarpus rotundatus Miq Danser or tumih is known as one of the fast growing species in the peat forests. Tumih wood has a straight trunk that could potentially be a good wood working materials, but there are no studies that describe the natural durability of wood tumih. The objective of this study was to test the natural durability of wood tumih from dry wood termites Cryptotermes cynocephalus Light, subterranean termites Coptotermes curvignathus Holmgren, decay fungus Schizophyllum commune, as well as its field natural durability in the grave yard test. Observed variables in this study were the percentage of termite mortality and weight loss of samples due to termites and fungal attacks. The result showed that the durability of tumih wood was not the same for all wood destroying factors. The natural durability of tumih wood belong to class III of C. cynocephalus, class II of C. curvignathus and class IV of decay fungus S. commune.

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.
