Abstrak: The mechanization technologiey have been applied in tofu industries, especially for soybean peeling. Many innovation and experiment that concern in peeling technology have been done by academician. The study of financial aspect in the application of such newly developed technology become important. The process of developing new technology should be enhanced with study on its financial aspects such as feasibility study. Purpose of this research is to have an engineering economy analysis on this developed technology, they are winnowing tray soybean peeler, hand paddle semi mechanical soybean peeler “ENGKOL23-BPTTG” and mechanical soybean peeler “OTOROL23-BPTTG” which developed by Center of Appropriate Technology Development. Evaluation of such alternatives were studied in order to obtain the conclusion of the best cost efficiency machine. Results of capacity testing of winnowing tray is 20 kg/hour, while for semi mechanical is 174.36 kg/hour and for mechanical peeler has the greatest capacity is 552.93 kg/hour. Thus evaluation method conducted using the base cost method indicated the “OTOROL23-BPTTG” had least cost at 20.926 ton and more soybean per year and the winnowing tray soybean peeler had least cost at 3 ton until 20.926 ton soybean per year.

Abstrak: Threshing is one of the important postharvest handling of soybean, where the use of proper threshing machine would be able to reduce the quantity losses and quality losses due to mechanical damage to the threshing process. Mechanical damage arising from the motion mechanism such as motion of stripping, hammering, and impact. Motion mechanism is very dependent on the drum cylinder speed threshing used. Therefore, this study aims to assess the performance threshing machine and analyze the magnitude of losses arising from threshing activities and to analyze the economic in operational of the threshers. This research was conducted in the Sindang Kasih village, Majalengka district with raw materials of Argomulyo soybean varieties. Threshing was done by using two multipurpose threshers, namely thresher A and thresher B as a test group with two treatments that was drum cylinder speed threshing of 515-570 rpm and 580-650 rpm. Observations were done at quantity and quality losses (split seeds, damaged seeds, and dirt). Quantity losses resulting from threshing activities were used to analyze the economics and feasibility of threshers. Economic analysis was done by determining the fixed costs, variable costs, BEP, cost of product and benefits of the threshing process, where feasibility of business was done based on of NPV, IRR, net B/C and payback period . The used thresher on a drum cylinder speed of 580-650 rpm produces the highest quantity and quality losses compared with 515-570 rpm of the both threshers operated. The highest quantity losses on a thresher A was 3.33 %, split seeds was 2.9 % and damaged seeds was 2.57 %, while the quantity losses on a thresher B was 0.72 %, 0.89 % of split seeds and damage seeds was 1.43 % on the thresher operated with drum cylinder speed of 580-650 rpm. The high losses produced at drum cylinder speed 580-650 rpm, therefore the operation of thresher should be done at 515-570 rpm of drum cylinder speed. From the economic analysis, the two threshing machine, was reached a feasibleoperational level with cost of product was Rp. 327/kg-Rp. 369/kg and BEP 15.7-19.2 ha equivalent to 23 562-28 852 kg seeds/year . This effort deserves to be developed with a range of NPV Rp. 1 997 037-Rp. 6523 947, 19.63-32.42 % IRR and a net B/C 1.11-1.43 in the applicable equipment rent wasRp. 400 / kg .

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.
