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: Basic properties, treatability, and finishing properties of tumih (combretocarpus rotundatus miq.) wood from central kalimantan
Abstrak: Penelitian ini bertujuan untuk menganalisis sifat dasar, keterawetan, dan finishing kayu tumih asal Kalimantan Tengah serta menganalisis pengaruh pengeringan awal dengan oven dan microwave terhadap sifat keterawetan dan finishing-nya. Hasil penelitian menunjukkan bahwa kayu tumih berwarna cokelat kemerahan, bertekstur kasar, berserat lurus, permukaan kayu mengkilap, dan bercorak. Pori-pori kayu tersusun dalam pola tata baur, didominasi oleh pori soliter meski dijumpai juga pori yang bergabung radial 2-3 sel. Diameter pori antara 68.50-510.90 μm dan berisi tilosis. Serat kayu tergolong kelas mutu III dengan panjang serat tergolong sedang (1338.39 μm). Kayu tumih lebih disarankan sebagai bahan baku mebel karena memiliki penampilan yang dekoratif, disamping sebagai bahan konstruksi (kelas kuat II; berat jenis = 0.63). Hasil uji keterawetannya memperlihatkan bahwa kayu tumih sukar diawetkan karena retensinya hanya 1.67-2.93 kg m-3 dan penetrasinya 13.22-40.66% atau 2.99-8.50 mm. Sifat finishing-nya tergolong baik (Grade 4B; ASTM D3359-02). Hasil uji finishing ini tidak dipengaruhi secara nyata oleh perlakuan cara pengeringan awal dan pengawetan borax yang diberikan., Tumih wood is a lesser-known wood species that has been used as construction material limitedly in some areas of Borneo Island. This study aimed to analyze the basic properties, treatability, and finishing properties of tumih wood and to analyze the influence of initial drying using oven and microwave to wood’s treatability and finishing properties. The result showed that tumih wood has reddish-brown colour, rough-texture, straight-grain, lustrous, and decorative. Pore distribution is diffuse, dominated by solitary but sometimes in radial-multipled of 2-3 cells. Pore diameter ranged between 68.50-510.90 μm, and contained tylosis. Its fiber was classified as quality class III and had medium length (1338.39 μm). The specific gravity of tumih wood was 0.63 that belongs to strength class II. Tumih wood is suitable for furniture manufacturing. Based on this study, the treatability of this wood was difficult because the preservative retention and penetration were 1.67-2.93 kg m-3 and 13.22-40.66% or 2.99-8.50 mm, respectively. Its finishing property was good (Grade 4B) based on ASTM D3359- 02, which was not affected by pre-drying treatment and borax preservation.

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.
