Abstrak: The objective of this research was to determine the effectiveness of tubular lamp construction to attract organisms in floating bamboo lift net and the best time interval to operate floating bamboo lift net. Lamp construction consisted of standard lamp, lamp with reflector, underwater lamp, and surface lamp without reflector as control. The research was started while floating lift net using lamps without reflector at 07.00 pm to 10.00 pm; the lamp with reflector between 10.00 pm to 01.00 am; and underwater lamp between 01.00 am to 04.00 am. The lamp operation series was changed at each floating bamboo lift net operation. Every lamp construction was operated 1-3 times in a time interval. Collected data were light illumination of each lamp construction in water, and weight and species composition of caught organisms. Data were showed on tables and graphs. Data analysis used descriptive comparative methods. The result of this research indicated that tubular lamp construction with reflector and underwater lamp had the best distribution light on floating bamboo lift net operation. Light penetration of both lamps were about 9 and 10 m, respectively. The standard tubular lamp spread in all direction with maximum light penetration of 6 m. Time interval between 07.00 pm to 10.00 pm and 01.00 am to 04.00 am were the effective time to catch organisms. Both time intervals produced 119.8 kg and 125.2 kg. While, time interval between 10.00 pm to 01.00 am was only 41.3 kg. The organisms that was caught by floating bamboo lift net consisted of 4 positive phototaxis organisms and 4 predator organisms. The positive phototaxis organisms were mackerel, indian mackerel, anchovy, and trasi shrimp. While the predator were hairtails, silver pomfret, cuttlefish, and little tuna. Lift net with underwater lamp caught heavier organisms than those tubular lamp with reflector and standard lamp, i.e. 151,7 kg, 95,9 kg and 65,6 kg in weight.

Abstrak: Stationary lift net operation is depend on the used of light bulbs. Fishermen nowadays uses tubular lamp as a source of light with high operating costs. Therefore, LED light was invented as an alternative. The goals are to prove that the LED lights can be used as a fishing tool on stationary lift net and to determine the best time of the fishing operation. Two stationary liftnet were used in this research. Four fishing activity were done in one experiment, which were done between 06:00 pm to 09:00 pm, 09:00 pm to 00:00 am, 00:00 am to 03:00 am and 03:00 am to 06:00 am. The results showed that the use of LED lights on the lift net produced 12 organisms with total weight of 167.1 kg, better than the light tubes that only produced 7 kinds of organisms with total weight of 128.2 kg. As for the best time of the catching on the lift net that uses LED lights is between 06:00 pm to 09:00 pm that produced 58.3 kg of catch, while the 09:00 pm to 00:00 am (42.9 kg), 00:00 am to 03:00 am (32.1 kg) and 3:00 am to 06:00 am ( 33.8 kg).

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.
