Judul: Optimasi Pola Tanam pada Lahan Pertanian dengan Mempertimbangkan Potensi Erosi, Land Rent, dan Kecukupan Beras di Wilayah Subang, Jawa Barat
Abstrak: Increasing population causes escalation in demand of land for food production, settlements, and public facilities. Meanwhile, land availability is fixed and limited which encourage utilizing marginal or unsuitable land. Land utilization for food production which not comply its capability would have negative effect both physically and economically. To avoid those effects, optimal cropping pattern should be determine to support sustainable agricultural development. This research aims to determine optimal land for food production areas by considering the potential erosion, land rent, and rice sufficiency. Linear goals programming is employed to devise the optimal choice of land use pattern. The study area includes four sub-districts in Subang, West Java namely Cipeundeuy, Kalijati, Pabuaran, and Patokbeusi. Optimum cultivation pattern on the agricultural land was organized to achieve three targets including (1) to minimized erosion for land preservation, (2) to provide the highest economic benefits for farmers, and (3) to meet rice sufficiency of study area. This study designed twelve scenarios with different targets combination. It is showed that scenario VI and XII is the best combination comply the expected targets. Both scenarios produce optimal cropping patterns with the lowest erosion values of 85.528,10 tons/year, generate the highest economic benefit for farmers at Rp 525.890.970.000,- and yield 46.598 tons rice for scenario VI and 181.730 tons rice for scenario XII. Decision tree analysis shows that the economic benefits strongly affected spatial distribution pattern of optimum land utilization.

Judul: Optimazion cropping pattern for the development agropolitan selupu rejang, Bengkulu Province
Abstrak: Program Agropolitan Selupu Rejang is the flagship to improve people's lives. It was started in 2002. This region is the largest producer of vegetable in Bengkulu province. Contribution of GDP and labor absorption in this region is dominated by the agricultural sector, but income of farmers in the agricultural district is still relatively low. The distribution of commodities and the demands leads to uncertainty price, making difficult for farmers to survive because of the economic value of a commodity decreases. Therefore we need a land use planning to optimize their potential. The purpose of this study was to: (1) know priorities of vegetables in the area and its influence factors, (2) optimize land use through alternative cropping patterns which is able to deliver optimal economic benefit by considering the time of planting and price of a commodity. This research is divided into several stages. The first stage is to establish the priority commodities, including determination of commodities using analysis of Location Quotient (LQ), and analyze characteristics of commodities using Localization Index (LI) and Specialization Index (SI). Analytical Hierarchy Process (AHP) was used to look at the factors and priorities that influence the selections of comodities. The second stage aims to determine the potential location for vegetables by overlaying land use map, RTRW map, and land suitability map. Third stage is arranging the cropping pattern. The fourth stage is to design a distribution pattern of each area and to see the impact of the implementation by optimization using Linear Programming. The analysis showed that red pepper, carrots, onions and cauliflower leaves are plants that have a comparative advantage. Dominant factor that determines the selection of commodities is the physical aspect (44.7%) with cropping capabilities throughout the year as the most influenting factor, economic aspects (33.7%) with capital as the most influenting factor and socio-cultural aspects (21.6%) with government support as the most influenting factor. Optimization results said that cropping pattern using linear programming methods gives farmer higher economic benefit about 637 thousand rupiahs - 2.439 million rupiahs per hectare per year rather than cropping patterns without optimization.

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.
