Judul: Efektivitas Lampu Tabung pada Perikanan Bagan
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.

Judul: Studi Pendahuluan Penggunaan Lampu Tabung Bereflektor terhadap Hasil Tangkapan Bagan Apung
Abstrak: The objective of the research was to determine effectiveness of the use of tubalar lamp with reflector to catch fish by using bagan apung. This research applied an experimental fishing method for one unit of bagan apung. It was taken at Palabuhanratu bay in August to September 2010. The treatment used both tubular lamp with reflector and tubular lamp without reflector were continuously treated then compared their catches. The measuring of the value of light illumination used two mediums, water and air then compared them. The highest value of light illumination was tubular lamp with reflector about 162,5 lux, in water medium and 562 lux in air medium, while the value of light illumination for tubular lamp without reflector was about 54,5 lux in water medium and 184 lux in air medium. The maximum illumination was accumulated by the light that bounce back from the edge of reflector and the light beam itself. The catchs had been increased after treated tubular lamp with reflector. The operation of bagan apung used silver reflector producing catchs a weight of 95,5 kg, it was more higher than tubular lamp without reflector a weight of 65,1 kg. The catch type had more variation, such as mackerel (Rastreliger sp), tembang fish (Sardinella fimbriata), tuna (Auxis thazard), pomfret (Pampus argentus), squid (Loligo sp), anchovy (Stolephorus sp), layur fish (Trichiurus sp), and small shrimp (Mysis sp). At the most catch there were tembang fish a weight of 21,8 kg for tubular lamp without reflector and 44 kg for tubular lamp with reflector. The catch of tubular lamp with reflector had more economic value than tubular lamp without reflector. The dominant catch type were tembang fish and promfet. Then they were followed by mackerel, tuna, and squid. On the other hand, anchovy and small shrimp could not be catched by the tubular lamp with reflector due to there were many predators and the research time was not right time, anchovy and small shrimp were not in season.

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.
