Judul: Comparative Use of Cod-end Mesh Size On Bottom Trawl in Tanjung Kerawang Waters
Abstrak: The research was conducted to compare catch-selectivity of cod-end with different mesh size. The research had implemented experimental fishing method and outfitted the cod-end with specially designed net-cover. The experimental trawl net was designed to have replaceable cod-end whereas the wings and bodys would remain the same. There were three different bags used in the research: 1 inch, 2 inch and 3 inch. Each bag was deployed and used in fishing operation three times. Data collected through enumerated and measured fish biometrics were caught both in the bag (cod-end) and in the net-cover. This research was conducted in two phases, a preliminary study which was conducted in August 2010, and then the main research in May 2011 on board of the Motor Boat Madidihang, a training fishing boat owned by the Ministry of Marine Affairs and Fisheries. The experimental fishing was conducted in the Cape Kerawang, West Java. The data was analyzed by comparing composition of the catch, diversity analysis (ANOVA) and analysis of selectivity of the catch. Main target fish observed in this study is threadfin bream (Nemipterus virgatus), sulphur goatfish (Upeneus sulphureus) and yellow striped goatfish (Upeneus vitatus). Results shows that after analyzed the data further using the least significant difference (LSD) formula, it became apparent that the usage of 2 inch and 3 inch mesh sizes gave significant effect to the escapement level of threadfin bream, sulphur goatfish and yellow striped goatfish. Therefore the research concluded that the environmental-friendly size for the cod-end in a trawl should be at or greater than 2 inch.

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: Tinjauan Patofisiologi Susunan Saraf Pusat Pada Distemper Anjing
Abstrak: Skripsi ini berisi tentang gangguan fisiologi susunan saraf pusat akibat infeksi virus distemper pada anjing. Distemper adalah suatu penyakit pada anjing yang disebabkan oleh virus distemper. Penyakit distemper mempunyai empat bentuk yaitu bentuk kulit, bentuk pernafasan, bentuk pencernakan dan bentuk saraf. Bentuk saraf merupakan bentuk yang kronis dan dapat menyebabkan kelumpuhan yang permanen pada anjing muda serta cacat anggota gerak seumur hidup pada anjing yang terserang infeksi. Gejala klinis saraf yang terlihat antara lain: konvulsi, inkoordinasi, chorea, berputar, kepala miring, myoklonis, paraplegia. Keadaan tersebut menyebabkan tidak berfungsinya beberapa saraf cerebral, cerebellar, vestibular dan sumsum tulang belakang serta ganglion basal. Virus distemper dapat menyerang susunan saraf pusat akibat virus tersebut mempunyai afinitas cel di myelin dalam otak dan sumsum tulang belakang dan memproduksi "inclusion bodies" di neuron, macrophag meningeal, endotel pembuluh darah arteri dan vena meningeal dan di sel glial. Virus distemper ini mempengaruhi metabolisme sel saraf, dimana oksigen untuk mengoksidasi glukosa guna pembentukan NADH menjadi ATP dimana ATP ini merupakan energi yang siap dipakai oleh sel saraf untuk menjalankan aktivitasnya akan terganggu. Apabila hal tersebut berlangsung dalam waktu yang lama akan menyebabkan kerusakan sel saraf, sehingga fungsi sel saraf (neuron) sebagai penghantar informasi akan terganggu seperti yang ditunjukkan oleh geiala klinis saraf. Penyakit distemper pada anjing ini masih merupakan problem bagi dokter hewan, walaupun usaha pengobatan telah banyak diupayakan.
