Abstrak: Until this time, majority of Indonesian farmers plant seeds by using a dibble (conventional method), that needs extra power, more human operators and is ergonomically inefficient. Therefore, a more precision seedling machine is needed to alter the manually seedling process into mechanically seedling process by using seed planter. A seed planter consists of mechanical component and electronic components. The mechanical component includes draft machine, dibble wheels, a supporting wheel, hopper, a metering device , a drainage tube, a fertilizer plot opener, and a covering hole device. The electronic component includes a metering motor, a micro-controller, a magnet sensors, a motor-driver and a electrical power supply. The design methodology used in this research is based on functional and structural design. Moreover, ergonomic values of the designed seed planter are also condidered based on the Indonesian average anthropometries. This dimension of the seed planter is of 130 cm (length) x 100 cm (width) x 90 cm (height) cm. The length of the connecting rod is 110 cm with a wheel diameter of drill 40 cm. The seed storage capacity of the hopper is 3.0 kg. The metering device diameter is 12 cm. The operating capacity of the croping tool is 11.63 hours / ha. The proposed seed planter is designed to be operated by a single human operator with pushing power of 223.71 watts. The enriched feature of the seed planter is precicesness of seeding and and multifunction capabilities (making seed holes, allocating seed & granular pesticide, closing seed holes, producing fertilizing rows).

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: 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.
