Judul: Semak Daun Island Aquatic Management Based On The Carrying Capacity in Conservation Coral Reef Ecosystem (Case Study: Water Semak Daun Island Administrative District Thousand Islands).
Abstrak: The existing floating cage culture activities in Semak Daun Island waters has enriched organic load to coral reefs ecosystem. The organic load came from food waste that enter the waters. Along with organic waste from various activities on land if not properly controlled lead to eutrophication, causing degradation of coral reefs through increased growth of macroalgae (overgrowth). Coral reef health in Semak Daun Island waters is indispensable for the success of sea ranching activities. It is necessary to study the condition coral reef ecosystems and assess the carrying capacity based on the optimal number of floating cages development activities, there for coral reefs ecosystem in Semak Daun Island waters remain sustain. This study was conducted from May to July 2013. The method used in this study is a survey method. Data collected included primary and secondary data. Analysis was done for percentage of coral and macroalgae coverage, herbivorous fish, aquatic productivity, estimation of organic waste and aquatic carrying capacity. Results showed that percentage of live coral coverage at Semak Daun Island waters are categorized moderate by the average percentage coverage of 44.95% and the average percentage cover of macroalgae was 42.24%. Herbivorous abundance is dominated by family Pomacentridae 32,140 individuals/ha. Chemical parameters for nitrate concentrations in the category mesotrofik, with a range of 0.136 mg/l - 0.364 mg/l. Waste loads estimation of net aquaculture that enter the waters was 1,178.1 Kg/ton/6 months of fish production (N 243.9 Kg/ton/6 months of fish and P 54.1 Kg/ton/6 months of fish). Estimated of anthropogenic waste load around the Semak Daun Island was 4,167 Kg N/6 months and 1,738.8 Kg P/6 months. Based on N load, the optimal - maximum carrying capacity of Semak Daun Island for grouper floating cages was 45 − 151 units (270 − 906 plot cages) or 2.8 – 9.4 ha of 9.99 ha area that appropriate for floating cage activities. In addition, based on dissolved oxygen, the optimal - maximum carrying capacity was 37 − 55 units (222 − 330 plot cages) or 2.3 – 3.4 ha of 9.99 ha area that appropriate for floating cage activities.

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.
