Judul: Analisis Gaya Pada Pintu Klep Air PastifasetModel Frame Lurus (PA-FG1)
Abstrak: The rate of food needs is directly proportional to the population growth; must be balanced with the development of agricultural technology innovations that can make use of all existing land conditions. The technology can be used in these circumstances is the application of tidal irrigation. The study aimed to analyze the force that occurs on hydromechanical sluice. Based on the results of the calculation, the maximum value of the placement reaction of HA is 1633.33 N, of HB is 3266.67 N, the value of style vertical slats sluice is 900 N and 3500 N. On the condition when the sluice opened, the greater the angle, the greater openings HA force. This is due to the resultant force of downstream greater than upstream. For sluice with head difference of 0.08 m, aperture angles 45o and 60o have differences with another sluice condition occurs where the force is inversely proportional to discharge. This can happen because the horizontal force component switches to the vertical component. The weight of the door is a major component of the vertical force the door itself. Budget plans are used to construct sluice is Rp177.888.400, -.

Judul: Design Of Variable Rate Fertilizer Applicator Frame
Abstrak: Frame for variable rate fertilizer applicator has been developed in order to mount the unit with the transplanter. The purpose of this study is to design and analyze its performance in paddy fields. The design of the frame unit was carried out with Computer Aided Design Software based on data obtained through the formulation and refinement of the idea of design and analysis of strength of material. The main function of the frame is to support hopper unit which has 120 kg weight. Variable rate fertilizer applicator unit consisted of four fertilizer hoppers, each equipped with a variable metering device which powered by a DC electric motor. Once designed, then prototype was built and its performance was tested in the experimental paddy field of the Mechanical and Biosystem Engineering Department, Faculty of Agricultural Technology, Bogor Agricultural University. The results of functional test and field performance test showed the designed prototype was function properly and was able to support the load generated by four filled hoppers full of fertilizer (120 kg). Average sinkage on an empty hopper was 21.60 cm, while the average sinkage on filled hopper was 24.74 cm. The average slip for empty hopper was 16.3% while the average slip for filled hopper was 20.2%.

Judul: Studi kasus skabies pada kucing di Rumah Sakit Hewan Jakarta periode Agustus 1997 - Juli 2000
Abstrak: Skabies pada kucing merupakan penyakit kulit yang disebabkan oleh infestasi tungau Sarcoptes scabiei atau Notoedres cati di dalam lapisan korneum kulit. Penyakit ini tergolong mudah untuk disembuhkan, terutama jika diagnosis pasti telah ditetapkan. Sejak Agustus 1997 sampai dengan Juli 2000 di Rumah Sakit Hewan Jakarta terdapat sebanyak 95 kasus skabies pada kucing dengan 80% diantaranya pada kucing yang memiliki rambut panjang, sedangkan 20% pada yang memiliki rambut pendek. Penderita skabies terbanyak berasal dari ras Persian (49,47%). Melalui metode pengobatan ivermectin (ivomec) dengan dosis 200 µg/kg berat badan secara subkutan, dilakukan dua minggu sekali, 77,89% penderita mengalami persembuhan, sedangkan sisanya (22,11%) berada dalam tahap persembuhan. Selanjutnya dari data tersebut dapat diketahui bahwa penderita dengan umur kurang atau sama dengan satu tahun memiliki tingkat persembuhan yang lebih baik daripada penderita dengan umur lebih dari satu tahun. Demikian pula halnya dengan kucing-kucing berambut panjang memiliki tingkat persembuhan yang lebih baik dibandingkan dengan yang berambut pendek.
