Judul: Effectiveness of soil and water conservation measures to reduce runoff and soil erosion on cacao plantation
Abstrak: Cacao plant is one of the major commodity of plantation in South East Sulawesi, especially in Konawe regency. Land management practices which is implemented by the local farmers on cultivating cacao, in many cases are not according to soil and water conservation principles. The research was aimed to study the effectiveness of several soil and water conservation practices on reducing runoff and soil erosion on cacao plantation with different land slopes and canopy coverages. The research was conducted in Amosilu village, Besulutu district, Konawe regency, the province of South East Sulawesi, from December 2006 to September 2007. The Experimental method in the field study was split plot design consisting three factors. The first factor was slope consisting two levels (10 – 15% and 40 – 45%) and the second factor was age of the cacao plant consisting two levels (5 to 7 month and 25 to 27 month) were used as main plots (P1 = 5 to 7 month and 10 – 15%; P2 = 25 to 27 month and 10 – 15%; P3 = 5 to 7 month and 40 – 45%; and P4 = 25 to 27 month and 40 – 45%), while the third factor, the vegetative conservation treatment was used as sub plots consisting three levels, i.e T1 = cacao with ground cover, T2 = upland rice and soybean rotation within cacao plant, T3 = upland rice and soybean rotation within cacao plant + Arachis pintoi as strip cropping. There was not interaction effect both cacao plant and slope treatment with vegetative conservation treatment on runoff and soil erosion with soil properties, exception on aggregate stability index. The result showed that vegetative conservation treatment (T3) with upland rice and soybean rotation within cacao plant with A. pintoi as strip cropping was best alternatif because it has been produced the lower rate of erosion (21,76 ton ha-1 year-1) compared tolerable soil loss value (22,44 ton ha-1 year-1) and improved of soil properties and has given a good benefit to famers from both upland rice and soybean.

Judul: Sustainable Farming System Planning Based On Cocoa In Way Semah Sub Watershed Lampung Province
Abstrak: Cocoa is a leading commodity in Lampung Province after coffee, because the cocoa plantations are widespread in almost district. One of the center of cocoa is Way Semah Sub Watershed which is including Pesawaran District administratively. However, cocoa productivity is still low because there is no arrangement of sustainable farming system based on cocoa. Thus have implication for lower average farmer’s income. Moreover, there is no soil conservation actions in actual farming systerm This study aimed to identify land use characteristics and to analyze the agrotechnologies and to compose sustainable farming system planning based on cocoa in Way Semah Sub Watershed. The rcommended agrotechnologies were meet sustainable farming system citeria : (1) the farming system which haspredicted erosion was lower than tolerable soil loss (ETol); (2) the farmer’s income was higher than a decent income; and (3) the agrotechnologies must be applicable and replicable by farmers. In this study, Land capability was evaluated using Klingebiel and Montgomery method, erosion was predicted using USLE (the Universal Soil Loss Equation ) equation developed by Wischmeier and Smith, and farming system was analyzed using cash flos analysis method. There is 4 (four) farming system type in intensive study site : cocoa monoculture (UT1), cocoa-coconuts (UT2), cocoa-coconuts-tangkil (UT3), and cocoa-trees-fruit plants. Result of this study showed that predicted erosion in actual agrotechnologies and cropping patterns was higher than ETol. It ranged from 89.90 to 425.80 tons hectare-1year-1 while ETol ranged from 18.42 to 32.30 tons hectare-1 year-1. Total farmer’s income were lower (Rp15 995 000 to Rp22 880 000 householder-1year-1) than a decent income (Rp.30.000.000 householder-1year-1). To increase farmer’s income, the source of income such as livestock was introduced into the existing farming system. Result of agrotechnologies simulation showed that conservation techniques of split pitch decrease predicted erosion ranged from 7.55 to 24.53 tons hectare-1year-1 and planting a shade plants result1.31 to 4.26 tons hectare-1year-1 lower than ETol. Fertilizer and livestock increase cocoa productivity and farmer’s income (Rp23 775 000 to Rp33 675 000 householder-1year-1) higher than a decent living.

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.
