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: The development of corn agroindustry nowadays is always followed by the development of sustainable mechanization technology. The mechanization technologies have been applied in corn production process, especially for soil tillaging, but not much applied in seeding process. Many innovation and experiment that concern in seeding technology have been done by academician. Yet the innovation have been well developed, the study of financial aspect in the application of such newly developed technology is often neglected. Besides the study of financial aspect is as important as study on its performance. Thus, the process of developing new technology should be enhanced with study on its financial aspects such as feasibility study. Purpose of this research proposal is to have a engineering economy analysis on newly developed corn seeding technology, they are semi-mechanical corn seeder “CO Seeders” which developed by Mechanical and Biosystem Engineering (Bogor Agricultural University) students, dibble corn seeder “V Model” and mechanical corn seeder “Grain Seeder” which developed by Development Center of Agricultural Mechanization. Evaluation of such alternatives will be studied in order to obtain the conclusion of a machine that has the best cost efficiency. Evaluation of alternative will be conducted using Present Worth Cost (PWC) method and base cost method. Engineering economic modelling with PWC method shown that the “Grain Seeder” mechanical type corn seeder is have the least cost at 61 ha and more whereas the base cost method have the “Grain Seeder” least cost at 37 ha and more .

Judul: Psittacosis Sebagai Zoonosis Penting Yang Berasal Dari Burung
Abstrak: Psittacosis atau ornithosis adalah penyakit menular dari burung kepada manusia. Agens penyebab psittacosis termasuk ke dalam virus psittacosis-lymphogranuloma venereum group yang disebut Chlamydia psittaci. C. psittaci hanya dapat berkembang biak di dalam jaringan hidup tetapi peka terhadap antibiotik. Penyebaran penyakit ini sangat luas, terdapat hampir di seluruh dunia. Di Indonesia penyakit ini belum pernah di diagnosa, tetapi mengingat terdapat demikian banyaknya jenis burung maka diperkirakan psittacosis ini sudah ada. Kasus pada manusia pertamakali ditemukan oleh Ritter pada tahun 1879, di Eropa. Waktu itu dikenal sebagai pneumotyphus. Chlamydia psittaci tidak hanya sebagai penyebab infeksi pada burung, juga bisa menyebabkan infeksi pada mamalia diantaranya sapi, kerbau, kambing, domba, babi dan kucing. Pada kucing dikenal sebagai feline pneumonitis. Pada domba atau kambing mengakibatkan enzootic abortion. Pada burung, kalkun merupakan unggas paling rentan diikuti oleh burung psittacine dan burung lain di luar famili psittacidae. Virulensinyapun berbeda-beda. Yang berasal dari kalkun bervirulensi tinggi, sedangkan yang berasal dari burung merpati bisa bervirulensi tinggi bisa juga bervirulensi rendah. Penularan terjadi melalui kontak langsung maupun ti- dak langsung. Penularan melalui telur tidak terjadi. Umumnya penyakit ini memperlihatkan gejala klinis berupa deman, lesu, lemah, anorexia, kurus, diarrhea ber- warna kekuningan, discharge dari mata dan hidung, conjunc- tivitis. Gejala khas pada kalkun adalah istirahat dengan sternum sebagai dasarnya, karena adanya tekanan dari bagian perut yang sakit. Sedangkan pada manusia memperlihatkan adanya demam, kadang-kadang merasa dingin, lesu, sakit kepala yang hebat, sakit pada bagian belakang badan dan photophobia…dst
