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: Economic Model of Sustainable Shrimp Farming System Management in Sidoarjo District, East Java
Abstrak: Indonesia is known as one of the top shrimp producing countries. In particular, Sidoarjo is one of the biggest districts that export shrimps, especially organic shrimp. However, Sidoarjo’s aquaculture production has currently shifted to produce milkfish instead of shrimp. For the farmers, shrimps seems to be more vulnerable to the water quality changes due to waste from domestic settlements or industry compared to milkfish. However in a good water quality, the cultivation of shrimp is more profitable because of its higher price. Producing shrimps within ecological carrying capacity and economic feasibility is the goal needed to be achieved in order to bring back Sidoarjo to be one of the biggest districts exporting shrimps. Decision makers, i.e. policy makers and farmers are challenged with the responsibility of planning and conducting aquaculture development in a sustainable way whereby social, ecological and economic goals are simultaneously achieved.For ecological sustainability, this research used water quality data translated into Pollution Index as an indicator. Cobb-Douglas production function is one of the methods used to know which input highly affects the shrimp production, continued by Business Feasibility Analysis i.e. Undiscounted Criteria methods that include Total Revenue, R/C and PBP and also Discounted Criteria such as NPV, Net B/C and IRR to see which system is feasible. Those three analysis was then used to build an economic model of sustainable shrimp-farming system using dynamic analysis with PowerSim software. Results from dynamic analysis then used for cost-benefit analysis in one area. Based on survey that has been done in Sidoarjo district from May 2013 to October 2013, using Pollution Index Analysis show that ponds 4 district in Sidoarjo are moderately polluted based on 9.2 Pollution Index Value. Analysis using regression for Cobb-Douglas Production Function stated that in traditional system production factors that statistically significant are pond area, harvest and pond preparation labor, dissolved oxygen and ammonia. In traditional plus system, pond area, fertilizer, Saponin and ammonia are statistically significant. The best shrimp cultivation system would be polyculture traditional between shrimps and milkfish which have NPV IDR 71,399,632, Net B/C 1.75 and IRR 26% compared to other monoculture traditional, monoculture traditional plus and polyculture traditional plus. The results of dynamic analysis also show that polyculture traditional system is more sustainable because it gave lowenvironmental impact and financially feasible with Total Profit IDR 474.367.511 for 82 ha shrimp ponds and Cost-Benefit Analysis shown NPV IDR 976,520,917, Net B/C 1.73 and IRR 26%.

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.
