Abstrak: Saturated soil culture (SSC) is a cultivation technology that provides continuous irrigation. It keeps water depth constantly and makes soil layer in saturated condition. By keeping the water-table constantly, soybean is avoided from negative effect of inundation on its growth because it will acclimatize and improve its growth. This technology appropriate to prevent pyrite oxidation on tidal swamps and has been proved to increase the productivity of soybean on nontidal swamp. The objective of the research was to determine the response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip, Tanjung Lago, Banyuasin District, and South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main-plot of the experiment was water depth in the furrow consisted of without watering, 10, 20, 30, and 40 cm under soil surface (USS). The subplot of the experiments was soybean varieties consisted of Tanggamus, Slamet, Wilis, and Anjasmoro. The result showed that the interaction between varieties and water depth significantly affected growth and seed production, but not for pod numbers/plant. The values of all variables were higher under SSC compared to those cultivated without watering, but varieties responded to SSC differently. Nutrient absorption of N, K and Mn by Tanggamus was higher than those of other varieties, except K, however K absorption of Tanggamus was not significantly different from Anjasmoro. P and Fe absorption of Tangamus tended to be higher than the other varieties, although statistically they were not affected by variety. The highest seed production was obtained from Tanggamus with 40 cm USS, i.e. 4.83 ton/ha but it was not significantly different from those at water depth 20 (4.63 ton/ha) and 30 cm USS (4.71 ton/ha). However, technically and economically, 20 cm USS was the most appropriate water depth for soybean production at tidal swamps.

Abstrak: The problems on tidal swamps are a condition of stress by Al-ex, Fe-ex and soil acidity. This condition decreased of soil nutrient availability. The utilization tolerant varieties and fertilizer combination under saturated soil culture technology has been proved to increase soybean productivity on tidal swamps. Saturated soil culture technology is a cultivation that gives continuous irrigation and maintains water depth constantly, as a result soil layer in saturated condition. This study aims to determine the tolerant of soybean variety and the best fertilizer combination under saturated soil culture on tidal swamps. The experiment was arranged in a split-plot design with three replications. The main plots was 4 kind of soybean variety and subplots was 10 kind of fertilizer combination. The result showed that the interaction between varieties and fertilizer combination significantly affected growth and productivity under saturated soil culture on tidal swamps. The highest productivity was obtained from Tanggamus with fertilizer combination of 200 kg/ha SP-36 + 100 kg/ha KCl + 1 ton/ha dolomite + 2 ton/ha manure, whose productivity up to 4.76 ton/ha

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.
