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).

Judul: Analisis Unjuk Kerja “Co Seeders” Prototipe II Alat Penanam Benih Yang Penanam benih yang presisi dan flexsibel
Abstrak: Regarding to the increasing of Indonesian corn demands, thus it will need more development of technology to support the increase of such productivity. The development of technology could be many ways and one of them is the development of mechanization technology. In order to support corn cultivation is seeding process which is also needed to develop a new technology in planting corn seeds. “CO Seeders” is offered solution due to its technology in planting corn seeds with precise and flexible operation system. “CO Seeders” abilities are make seedbeds, précising the number of seeds, close the bed and make a burrow path for fertilizers. Moreover, in planting corn seeds “CO Seeders” work at 20 x 80 cm planting area. It has 2 type of drill which have different ability in making the seedbed hole. The first is the triangle prism type drill which is obtain 3.65 cm depth of the seedbed hole and the other is the cone type which obtain 4.9 cm depth of the seedbed hole. The ration of seed planted with triangle prism drill is 75% and 64.5% for cone drill. From experiment “CO Seeders” performance provide different results of each drill type. “CO Seeders” with triangle prism drill type capacity obtained is 11.65 hours/ha with 85% field efficiency and the cone drill type capacity is 12.5 hours/ha with 63.49% field efficiency. Nevertheless in operating such machine problems still occurred. There are problem in rotation of furadan metering device because of furadan grain still clogged the gap between hopper and metering device which make the device stuck and won’t rotate constantly.

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.
