Judul: Sustainable farming systems for Rubber and Oil Palm Planning in Batang Pelepat Watershed Bungo District Jambi Province
Abstrak: Land for rubber and oil palm farmings in Batang Pelepat watershed were generally cultivated without adequate fertilization and soil and water conservation techniques. This practice caused high erosion and in turn gradually decreased land productivity and farmer’s income. The objectives of this research were:(1) to identify land characteristics and farming systems of rubber and oil palm (FSROP) types, (2) to study impacts of FSROP on land characteristic, run off and erosion (ROE) rate, crop production and farmer’s income and (3) to design sustainable FSROP. Identification of FSROP characteristics were carried out by using descriptive analysis. Impacts of FSROP on ROE was measured in small erosion plot and analyzed using variance analysis and Duncan New Multiple Range Test (DNMRT). The sustainable FSROP was formulated by simulation technique using universal of soil loss equation (USLE) and multiple goal programming models. The results of the research showed that farming system in Batang Pelepat watershed consisted of five types of rubber farming systems and two types of oil palm farming systems. All of those farming systems were not able to fulfill indicators of sustainable agriculture (ISA). Cultivated land resulted higher ROE than forest. However among the cultivated land sesap karet caused the lowest ROE (3.53 mm and 13.93 ton/ha/year). The sustainable FSROP could be accomplished by application of combination agrotechnologies including balance fertilization using urea, SP-36, KCl and MgSO4. Meanwhile, the ISA were accomplished by application of Legum Cover Crop (LCC) and countour cropping (on slope 3–14%) and LCC and gulud terrace (on slope 15–30%). The sesap karet I (mixed of rubber-manau-kayu sungkai) performed the most optimum ISA. The sesap karet I generated erosion of 0.61 – 3.46 ton/ha/year and the farmer’s income Rp18 320 000 –18 590 000/ha/year.

Abstrak: Established agricultural practices in upland vegetable growing areas in Indonesia are generally implementing up and down the slope cultivation with relatively high rates of fertilizers and pesticides applications. Combined with high rainfall intensity, these practices have contributed to high runoff and severe erosion and in turn gradually decreased land productivity and farmers income, thus unsustainable farming systems. The objectives of this research were : 1) to identify and describe existing conditions of the potato based vegetable farming systems, 2) to study soil conservation measures alternatives to control soil erosion and obtain optimal net farm income, and 3) to design potato based sustainable vegetable farming systems in Siulak Watershed, Kerinci District, Jambi Province. Land biophysical and farmers characteristics as well as agrotechnologies were identified through soil survey and farmers interview, while alternatives of soil conservation measures were studied through soil erosion plot experiments. Models of patato based sustainable vegetable farming system were formulated by simulation using Universal of Soil Loss Equation (USLE) model and multiple goal programming. Results of the research showed that up and down the slope vegetable farming practices and inadequate of soil conservation practices caused soil erosion rate of 39.25 - 229.14 ton/ha/year which was higher than the local soil tolerable loss (24.09 - 20.89 ton/ha/year), and net farm income was generally not enough to support life worthed living (Rp 28 000 000/year). Planting on ridges across the slope, or ridges constructed 15 degrees across the slope, or in ridges down the slope with a mound constructed across the slope in each 4.5 m distance and silt-pit, can be considered as alternatives soil conservation methods for vegetable farming systems. Potato based sustainable vegetable farming systems in Siulak Watershed could be accomplished by improving the cultivation practices by integrating the soil conservation methods (planting on ridges across the slope and mulch, or ridges down the slope with a mound constructed across the slope, mulch and silt-pit) into the existing systems. Potato based sustainable vegetable farming systems with the cropping pattern of potato-cabbage-tomato and recommended agrotechnologies performed the most optimum models in Siulak Watershed, Kerinci District, Jambi; this system generated soil erosion about 10.59 - 18.82 ton/ha/year and the net farm income about Rp 40 714 558 - Rp 52 745 652 per hectar per year on 0.44 ha farm area. Some farmers in Siulak Watershed have started applicating the recommended agrotechnologies right after the research was completed.

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.
