Judul: Alokasi Optimal Pemanfaatan dan Nilai Land Rent Sumberdaya Tambak di Kecamatan Tanah Merah Kabupaten Indragiri Hilir Provinsi Riau
Abstrak: The aims of this research are to analyse the optimal allocation rate of resources utilization of pond culture, to estimate and to analyse land rent value of prawn pond culture and to estimate affect of change in exogeneous variable on the land rent value. Finding of the research shows that economic value of prawn pond culture of 92 ha in Tanjung Pasir Village, is estimated to be Rp163.862.746,11 per year and a total of 76 ha in Tanjung Baru Village is Rp6.191.627,23 per year. Based on Ricardian land rent concept, Tanjung Baru Village has land rent value of Rp1.560.182,00 per ha, while Tanjung Pasir Village has about Rp1.065.431,00 per ha. Multiple regression model, applied for this research indicates that there is a corelation between land rent value and productivity factors and distance. The model has also shows that factor productivity has a positive correlation to the land rent value, while distance has a negative correlation to the land rent value. It is also indicated that Tanjung Baru Village has reached almost an optimal condition. The finding of sentivity analysis shows that the increase of oil price and urea fertilize reduced the value of land rent and the magnitude of change in the value of land rent be affected by the factor of fertility rate and the distance of the pond location from the existing local spot market.

Judul: Analisis Nilai Land Rent dan Optimalisasi Pemanfaatan Lahan Tambak Bandeng di Kelurahan Marunda, Jakarta Utara
Abstrak: The purposes of this research were to identified the production of bandeng fishpond activity, estimates the land rent value based from water source, and optimization activity from bandeng fishpond in Kelurahan Marunda. The method used this research were descriptive analysis, land rent value analysis, optimization analysis and sensitivity analysis. The result shows that the input of fishpond bandeng production in every unit is the land, seed, labor, manure, pest control, vitamin, feed, and water use. The land rent value of the fishpond bandeng at BKT water user is Rp 2.093.961,52 per ha. While land rent value at sea water user is Rp 1.039.702,06 per ha. The analysis informs that the unit of analysis of BKT water user has a surplus of land larger than the unit of analysis of sea water users. This illustrates that land use activities from milkfish ponds in the unit of analysis of BKT water users is more efficient aspects of selling power output and fertility of the land. In addition, this study also analyzed the optimization of production inputs to construct the objective function to maximize the value of rents. This is to determine the efficient level of milkfish ponds at Marunda in economically. Optimization and sensitivity analysis results indicate that the use of optimal inputs and rising prices give a positive land value, so that the activity is feasible

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.
