Judul: The Study of Ecology -Ecomonics Models for teh Development of Brackish Water Shrimp Pond In Randangan, Kecamatan Marisa, Kabupaten Pohuato, Gorontalo
Abstrak: The objective of study is to build a sustainable development model for brackish water shrimp pond. Mangrove ecosystem has an ecology and economic function in coastal area of Randangan, it has been used for brackish water shrimp pond. The development of shrimp pond grows rapidly and tends to endanger the sustainability of the mangrove ecosystem. The shrimp pond aquaculture is also giving an ecological impact to coastal area through pond effluent. Therefore, it is important to model the development of brackish water pond considering the carrying capacity, economics value of mangrove ecosystem and profit ability of shrimp pond aquaculture. The result shows that : (1) based on spatial analysis 1.917,01 ha is suitable for shrimp pond in Imbodo, Duhidaa, and Manawa (coastal village), but wing carrying capacity model only 759,I ha can k developed in sustainable way; (2) simulation of the model showed that intensive shrimp pond technology give the highest profit (Rp 95 million per ha per crop) with the concentration of NO3-N of 10.807 ppmlhdcrop (1 20 days) or 0.29lhalday; and (2) ecology-economics model indicated only 30 % of the mangrove area can be developed for intensive shrimp pond.

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.
