Judul: Kajian teknis kecepatan kapal jukung di Ur Pulau Maluku Tenggara
Abstrak: This research was carried out based on the need of maximum speed of ketinting boat (dug out boat equipped with machine) using some values of horse power (HP) sechas : 5,5 HP; 6,5 HP or combination 5,5HP + 6,5 HP. In the fishing operation, this boat is equipped with long shaft to connect machine with the propeller. This arrangement produce some degrec of angles between propeller the boat. Experimental method was applied in this research. Two kinds of boat were used suchas, boat with stabilizer (katir) and the one without stabilizer. The result show that maximum speed of boat (5-6 knot) is obtained by applying machine with 6,5 HP equipped with long or semi log shaft with cartain angles. Besides, fuel consumption on this power rate is the most efficient.

Judul: Keragaan Mesin Penggerak Perahu Motor Tempel di PPI Pasauran, Serang, Banten
Abstrak: Outboard engine is used by the majority of fishermen in Indonesia. Therefore, it is necessary to do research about performance of outboard engine. This research is conducted in PPI Pasauran Serang Banten. The objectives of this research to identify part of outboard engine, calculate with theorist method the best speed for outboard vessel in PPI Pasauran, and to calculate with theorist average amount of fuel that needed by outboard fishing vessel per trip in PPI Pasauran. Data analysis is being done with comparative-numeric between marine outboard engine and long shaft outboard engine. Outboard engine are consist of motor, shaft of propeller, propeller, and carburetor. Best theorist speed that used by PPI Pasauran Fishermen to operate marine engine outboard are 4,59-4,72 knot and to operate long shaft outboard engine are 4,04-4,27 knot. Theorist amount of fuel that needed by marine engine outboard fishing vessel are 40-60 liter per trip and theorist amount of fuel that needed by long shaft outboard fishing vessel are 6-12 liter per trip.

Judul: Enteric Collibacillosis Pada Anak Babi Baru Lahir: Patogenesa dan Perubahan-Perubahan Patologisnya
Abstrak: Diare disebabkan oleh infeksi bakteri Escherichia coli pada anak-anak babi baru lahir yang peka terhadap en terotoksin produk bakteri tersebut. Dikenal sebagai colibacillosis. Patogenesa dari colibacillosis anak babi baru lahir adalah (1) infeksi oleh E. coli patogen, (2) proliferasi E. coli di lumen usus halus, (3) produksi dan pelepasan enterotoksin, dan (4) aktifitas toksin pada usus halus. Dalam proses proliferasi, adanya antigen pili K88 sangat penting karena memungkinkan bakteri perlekatan dengan epitel mucosa usus halus. mengadakan Setelah ko lonisasi dan proliferasi segera toksin dilepaskan. Akti- fitas toksin menginduksi sekresi yang berlebihan dari u- sus sehingga banyak cairan yang dikeluarkan ke lumen usus. Hal ini mengakibatkan banyak cairan dan elektrolit hilang sehingga timbul diare, dehidrasi dan asidosis yang sering menyebabkan kematian. Perubahan-perubahan patologis yang umum adalah dis tensi usus halus, dilatasi lambung dan infark pada kurva- tura mayor. Perubahan-perubahan histologis yang terjadi adalah enteritis hemorrhagica acuta, oedem dan kongesti pembuluh darah di lamina propria, akumulassi leukosit inti polimorf, sel monosit, dan inti sel mengalami piknosis Thrombus pada vena dan degenerasi serta desquamasi sel epitel usus….
