Judul: Pengaruh Cara Pengomposan dan Dosis Kompos Jerami terhadap Pertumbuhan dan Produksi Kedelai (Glycine max L. Merr) pada Budidaya Jenuh Air di Lahan Pasang Surut
Abstrak: Saturated soil culture (SSC) is a cultivation technology that gives continous irrigation and maintains water depth and makes soil layer in saturated condition. By keeping the water-table constantly, soybean will be avoided from negative effect of inundation on soybean growth because soybean will acclimatize and improve its growth. 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. The objective of the research was to study the composting and dosage of compost rice straw to growth and production of soybean (Glycine max L. Merr) at saturated soil culture on tidak swamps. The research was conducted at Banyuurip of Tanjung Lago Sub District, Banyuasin District, South Sumatra Province, Indonesia from April to August 2010. The research was arranged in a randomized complete block design, two factorials. First factor was composting system, consisted of composting by effective microorganism and composting by manure, lime, and urea. Second factor was dosage of compost, consisted of without compost, 5, 10, and 15 ton compost/ha. Therefore there are 8 treatment combinations, each treatment combinations was repeated 3 times so there are 24 plots. Composting system was significantly different from height at 4 week after planting (WAP) and the number of leaf at 6 WAP. Dosage of compost was significantly different from height at 2 and 4 week after planting (WAP) and seed productivity. Productivity in composting by effective microorganism was higher but not significantly different from manure, lime and urea. Optimal dosage was 10 ton/ha. Productivity of 10 ton/ha compost was 2.62 ton/ha, not significantly different from 15 ton/ha compost (2.46 ton/ha) and significantly different from 0 ton/ha compost (2.16 ton/ha) and 15 ton/ha compost (2.17 ton/ha). Key words: Glycine max (L.) Merr., tidal swamps, compost.

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.

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.
