Judul: Estimation oc coastal zone carrying capacity for brackish water culture development based on the biodegradation rate of shrimp culture effluent in coastal waters of Serang Regency
Abstrak: Penelitian ini bertujuan mengestimasi day dukung lingkungan pesisir Kabupaten Serang untuk pengembangan areal tambak udang berdasarkan laju biodegradasi limbah tambak di perairan pesisir, dan mengidentifikasi mikroba yang paling efektif mendegradasi limbah organik tambak (OSS) dan membentuk nitrat (nitrifikasi). Hasil percobaan dengan 6 perlakuan memperlihatkan bahwa kadar TSS/OSS berpengaruh sangat nyata (p < 0,01) terhadap laju biodegradasi OSS dalam media percobaan.

Judul: Optimasi pemanfaatan wilayah pesisir berbasis daya dukung bagi pengembangan budidaya tambak udang di Kecamatan Mangara Bombang, Kabupaten Takalar, Provinsi Sulawesi Selatan
Abstrak: The aims of this research are to study land suitability for development of intensive/semi intensive and traditional/traditional plus shrimp culture, to determine carrying capacity, and optimize of land utilization for shrimp culture development. The methods employed in the research include:(i) field survey for assessing the biophysics characteristics of the Mangara Bombang coastal area; (ii) Geographycal Information System (GIS) for suitability analysis; (iii) Carrying capacity analysis using 3 different technique, and (iv) dynamic modelling for optimization. Results of land suitability for intensive/semi intensive shrimp culture showed that 894,284 hectares are highly suitable (SS), 663.071 hectares are suitable (S), and 1517.649 hectares are less suitable (KS). While land suitability for traditional/traditional plus shrimp culture showed that 1148.478 hectares are highly suitable (SS), 1078.667 hectares are suitable (S), and 1031.941 hectares are less suitable (KS). The total water volume of shrimp culture is about 129 152 399.22 m3. The water’s carrying capacity to receive organic waste based on oxygen content about 826 947.02 kg of organic waste /day. Based on that carrying capacity analysis, the generated land allocation for intensive shrimp culture (126 shrimp/m2), intensive shrimp culture (50 shrimp/m2), semi intensive shrimp culture (25 shrimp/m2), and traditional plus shrimp culture (8 shrimp/m2) consecutively are as follow 89.61 hectares, 346.37 hectares, 715.79 hectares, and 1694.91 hectares. While for water’s carrying capacity based on biodegradation rate of organic waste, the generated land allocation for intensive shrimp culture (126 shrimp/m2), intensive shrimp culture (50 shrimp/m2), semi intensive shrimp culture (25 shrimp/m2), and traditional plus shrimp culture (8 shrimp/m2) consecutively are as follow 17.49 hectares, 454.13 hectares, 938.50 hectares, and 2222.25 hectares Waters’s carrying capacity based on assimilation capacity was 70.38 tons of N (1152.13 tons of shrimps) or 47.84 tons of P (2874.tons of shrimps). Based on simulation of dynamic modelling obtained which generated land allocation of high optimization are intensive shrimp culture (126 shrimp/m2) 26.62 hectares, intensive shrimp culture (50 shrimp/m2) 144.69 hectares, semi intensive shrimp culture (25 shrimp/m2) 282.36 hectares, and traditional plus (8 shrimp/m2) 503.43 hectares, with total production 2453.03 tons of shrimp. Optimization economic profit and actual labour are Rp 36 328 006 033 and 1753 people. After that, land allocation scenario 2 for second alternative are intensive shrimp culture (126 shrimp/m2) 12.48 hectares, intensive shrimp culture (50 shrimp/m2) 89.95 hectares, semi intensive shrimp culture (25 shrimp/m2) 168.11 hectares, and traditional plus (8 shrimp/m2) 236.12 hectares, with total production 1371.09 tons of shrimp. Optimization economic profit and actual labour are Rp 19 927 489 483 and 981 people.

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.
