Judul: Effect of sediment on scleractinian corals community in derawan islands, east kalimantan
Abstrak: There are some indications that run-off from Berau River gives negative impact on scleractinian corals community in Derawan Islands. Many activities occured in the upland beside of the Berau River such as deforestation, coal and sand mining increased the sedimentation in the Derawan Islands waters, direct or indirectly. Sediment through shading and smothering cause corals in stress condition and eventually death for some species. The purpose of this research is to study about the effect of sedimentation on scleractinian corals in Derawan Islands, East Kalimantan. The quadrate transects placed at each station to estimate live coral coverage. The stations represent distance from Berau River. Rapid Ecological Assessment (REA) used to get coral species richness by The Nature Conservancy (TNC) in 2003. A sediment trap placed for 14 days in each station to have sedimentation rate. Sample of sediment were analyzed in the laboratory. Sedimentation rate (mg/cm2/day) decrease in number from station Panjang Island to Maratua Island. The coverage and species richness of coral reefs have negative correlation to sedimentation rate, which mean high sedimentation tend to cause low species richness and coral coverage. The lowest number of species richness and scleractinian coral coverage found in Station 1 which nearest distance to Berau River with high sedimentation rate.

Abstrak: Sedimentation is one of some limiting factors for coral distribution. Tanjung Pemancingan waters Kotabaru influences by sedimentation coming from river, runoff and activity of coal port mining. The aims of this research are to (1) study hard coral coverage, montatily, abuncance and genera colony, (2) study sedimentation rate and characteristic of environment econditions, (3) analyze correlation of the hard coral community follow with of sedimentation rate, (4) analyze distribution between hard coral community follow with of sedimentation rate and enviromental conditions different.

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.
