Judul: The efficiency of deep-well pump irrigation for dryland farms in east Lombok, West  Nusa Tenggara: a non-radial approach
Abstrak: Since 1981 until now on, the local government has developed deep well pump irrigation to anticipate the decreasing of dryland area and fertility in Lombok. The increase use of dryland nowadays needs the farmers to run farms more efficiently. The variations of farmers backgrounds and their managerial capacities inevitably affect their efficiency rate. This study aims at (1) investigating the use of pump irrigation for dryland farms; (2) developing an approximation to figure out the distribution efficiency from pump house to individual farms; (3) identifying the irrigation efficiency levels achieved by individual farmers and determinant factors affecting the efficiency. The stratified random sampling was applied to get samples of corn and onion farms, differed by high and lowland. Primary data used in this research were collected using a survey technique by interviewing 246 farmers and 49 pump operators in East Lombok during two months periode, based on specific designed questionnaire which previously tested. The study found that (1) the deep well pump irrigation has increased the cropping intensity of dryland schemes from 100 to 261 percent per year; (2) the distribution of irrigation water from pump house to individual farms has been efficient, indicated by a high index of distribution efficiency; and (3) the application of existing technology for irrigation is inefficient. Improving irrigation efficiency can save water about 30, 42 and 44 percent from existing use for corn, lowland onion and higland onion respectively. Using 14 variables in linear additive model, it is found that 9, 5 and 2 variables are significant to explain the irrigation efficiency for the three crops respectively. Experience in running farms in schemes, formal education years, farm cost ratio, and farm income ratio indicate positive effects on the irrigation efficiency. While farmers‟ age, family size, frequency of attending training, and land area cultivated indicate negative effects for corn farms. Improving training and farmers organisation are adivisable to increase the irrigation efficiency.

Abstrak: The research of the influence of dose management on water irrigation and Corn’s below leaf prune to the Lamuru productivity in the dry climate area has been done. This research was conducted on the Naibonat Expriment Farm, East Kupang Sub District, Kupang, Nusa Tenggara Timur, from June to October 2011. The area has been used is 72 m x 32 m using Split Plot Design Methods. This research was using two treatments; the first treatment is conducted on the main plot with water irrigation dose given 100%, 80%, 60%, and the dose control is appropriate with the Farmer’s custom. The second is conducted to the Corn’s leaf at the generative phase through with and without leaf pruning on the determined sub main plot. The result has showed that water irrigation dose treatment between 80% and 60% is significant to the Corn’s productivity that is 7.7 ton/ha and 5.3 ton/ha, but not significant to the control (7.0 ton/ha). On the other hand, the treatment with and without leaf prune are not significant to the growth component because the prune is conducted at the generative phase. The Anova test result has not showed the significance between the treatment of with and without leaf prune to the Corn’s productivity. The 80% dose of water irrigation could thrift the water until 842 m3 or 20% per one planting season in one hectare. Meanwhile, the farmer’s custom has lavished of the water until 2.105 m3 or 50% per one planting season in one hectare. Based on the analysis, the optimizing of water irrigation interval is seven times along one planting period which is more efficient than Farmer’s used with fourteen times along one planting period.

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.
