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.

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: 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.
