Judul: Pengaruh Perbedaan Ukuran Mata Jaring Rampus terhadap Hasil Tangkapan Ikan Layang (Decapterus kurroides) di Perairan Cisolok, Palabuhanratu, Kabupaten Sukabumi
Abstrak: The purpose of this research is to determine the catch composition and diversity of monofilament bottom gillnet of different mesh size, to determine the catch of redtail scad (Decapterus kurroides) by using monofilament bottom gillnet with different mesh size, and to determine the difference of capture mechanism of redtail scad (Decapterus kurroides) on the monofilament bottom gillnet with different mesh size. The research was done by experimental fishing method using monofilament bottom gillnet with different mesh size (44.5; 50.8; 63.5; and 76.2 mm (1.75; 2; 2.5 and 3 inches)). The arrangement of mesh panel on the set of monofilament bottom gillnet was alternated during fishing trials for giving equal opportunities of fish to be caught. The catch diversity is analyzed using the Shannon Wiener index. The statistical test, i.e.,Friedman test and multiple comparison test are used for significantly test of the catch. The result showed that total catch of monofilament bottom gillnet 529 individuals, consisted of six species. The catch dominant was redtail scad (Decapterus kurroides) with number of 351 individuals or 66.35% of the total catch, followed by goldband goatfish (Upeneus moluccensis) with number of 67 individuals or 12.67% of the total catch. Based on the different mesh size of monofilament bottom gillnet, redtail scad was the main catch of monofilament bottom gillnet with number of mesh size 2.5 was 161 individuals (45.87%). Generally, the redtail scad caught in entangled reached in total 269 individuals (76.64%) of which mesh size 1.75 inches caught 28 individuals (10.41%), mesh size 2 inches caught 70 individuals (26.02%), mesh size 2.5 inches caught 129 individuals (47.96%), and mesh size 3 inches caught 42 individuals (15.61%).

Judul: Pengaruh Perbedaan Mesh Size Jaring Rampus terhadap Hasil Tangkapan Rajungan (Portunus pelagicus) di Teluk Jakarta, Muara Angke
Abstrak: The objectives of this research were to determine the catch composition and diversity of monofilament bottom gillnet in different mesh size, to count the swimming crabs (Portunus pelagicus) caught by monofilament bottom gillnet in different mesh size. This research was conducted by experimental fishing method using monofilament bottom gillnets which have different mesh size (3; 3,5 and 4 inches). The arrangement of mesh panel on the set of monofilament bottom gillnet was operated in turns during fishing trials for giving equal opportunities of fish to be caught. The statistical tests, ANOVA test and BNT test, were used to examine the number of the catch. The result showed that total catch of monofilament bottom gillnet was 405 individuals, consisted of six species. The largest catch was swimming crab (Portunus pelagicus) which made up 235 individuals or 58% of the total catch. Based on the mesh size of monofilament bottom gillnet, it can be seen that swimming crab was the main catch of the 3 inch monofilament bottom gillnet which constituted 126 individuals (54%).

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.
