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: Studi Kasus: Patomorfologi Trakheobronkhitis Supurativa Pada Kucing (Felis Catus).
Abstrak: Trakheobronkhitis merupakan penyakit saluran respirasi yang sering terjadi pada hewan kecil, terutama anjing dan kucing. Penelitian berupa studi kasus ini bertujuan untuk mempelajari patomorfologi trakheobronkhitis supurativa pada kucing. Perubahan patologi anatomi berupa eksudat purulen pada lumen trakhea dan warna paru-paru yang tidak homogen, warna lebih gelap pada salah satu lobus, dan permukaan paru-paru lebih menonjol. Perubahan histopatologi berupa badan inklusi amfofilik-eosinofilik intranuklear yang dikelilingi oleh clear halo dan titik-titik kromatin ditepinya pada epitel kelenjar trakhea dan epitel bronkhiolus. Badan inklusi ini merupakan ciri dari FHV-1 dan adenovirus. Pada trakhea juga ditemukan koloni bakteri berbentuk coccobacillus sebagai infeksi sekunder. Bakteri tersebut diduga Bordetella sp. yang sering menginfeksi saluran respirasi kucing. Deskuamasi terjadi pada epitel trakhea dan bronkhiolus. Selain itu, ditemukan juga sel radang limfosit, makrofag, sel plasma, dan neutrofil. Pada paru-paru ditemukan lesio bronkhiolitis. Ditemukan juga bronkhopneumonia yang ditandai infiltrasi sel radang neutrofil dan sel nekrosis pada lumen bronkhiolus. Paru-paru juga mengalami emfisema dan edema pulmonum. Hiperemia dan hemoragi juga ditemukan pada kapiler paru-paru. Pada kasus ini, trakheobronkhitis supurativa diduga disebabkan oleh FHV-1, adenovirus, dan bakteri jenis Bordetella sp.
