Judul: Studi Daerah Penangkapan Ikan di Selat Malaka Melalui Evaluasi Hasil Tangkapan yang Didaratkan di Pelabuhan Perikanan Samudera Belawan
Abstrak: The entepreneurs generally thought that a lot of catches indicated potential fishing region. However, the environmentalists and biology experts scrutinise whether the catch is often obtained by fishing are included in the category are worth catching in biology. Although the catch a lot, but if the fish that are caught are dominated by fish that have not been worth caught in biology, then the region of the arrest is categorized not potential. The Malacca Strait is one of the fishing ground for the fishermen who is based in the Belawan’s Ocean Fisheries port and the condition of the fishing ground in the waters is not widely known yet. This research aims to determine the composition of the amount, type and size of the length of the fish that caught in the waters of the Malacca Strait and then evaluate the condition of the fishing ground in the Malacca Strait based approach to the compotition of the catches. The methods that used in this research is the survey method. The catch during the research consists of 28 kinds of fish as much as 120.021 kg with the type of fish that most caught there are 3 types, namely tetengkek (Megalaspis cordyla), layang (Decapterus russelli) and selar hijau (Atule mate). The composition of the amount, type and size of the fish caught in the waters of the Malacca Strait is relatively varied. The potential fishing ground in the waters of the Malacca Strait in the region tend to be away from the coast, while the fishing ground that belonging to the categories less potential tend to be in the waters near the coast.

Judul: Evaluasi Daerah Penangkapan Ikan Layang (Decapterus spp.) Berdasarkan Indikator Komposisi Hasil Tangkapan, Suhu Permukaan Laut dan Klorofil-a
Abstrak: Determination of accurate fishing ground gives influence on efficiency of fishing operation and productivity. However, fishermen in the northern part of Aceh have difficulties in deciding the position and resulting to the minimum yields. The objective of the research were: (1) to determine the distribution of sea surface temperature (SST), and a-chlorophyll in the north water of Aceh, (2) to determine the composition catch number and size of indian scad (Decapterus spp.) in north water of Aceh, (3) analyzing the relationship between SST and chlorophyll on the catch number and size of indian scad in north water of Aceh, and (4) predicting potential fishing ground in the north water of Aceh. Data were obtained from field data (in-situ) and satellite image data (ex-situ). It was performed by three steps, (1) field surveying in the study location, (2) collecting field data, and (3) downloading SST image and a-chlorophyll from MODIS satellite. Results showed the relationship between SST and chlorophyll is not significant towards catch number and size length of indian scad. Furthermore, SST and chlorophyll are varied in each seasonal period at the range from 27.53oC to 28.83oC and from 0.20 mg/m3 to 0.22 mg/m3. Sizes of fish captured using purse seine are not complying with the current standard and are included under category of restricted to be captured. The most potential fishing ground of indian scad in north water of Aceh during January-March 2012 located Pulo Beras waters.

Judul: Babesiosis pada kuda
Abstrak: Babesiosis pada kuda adalah penyakit menular yang di- sebabkan oleh Babesia caballi dan Babesia equi, yaitu pa- rasit protozoa perusak sel darah yang termasuk dalam genus Babesia. B. equi diduga oleh beberapa ahli termasuk dalam genus Theileria. Karena itu klasifikasi genus Babesia di- bicarakan dan siklus hidup B. caballi dan B. equi diulas. Kuda pada semua umur dapat terserang oleh dua parasite tersebut di atas. Tetapi kuda-kuda yang sudah dewasa (tua) lebih rentan jika dibandingkan dengan kuda-kuda yang masih muda. Kasus-kasus yang paling sering dijumpai adalah kasus-kasus yang bersifat akut walaupun kasus-kasus yang bersifat perakut, subakut dan kronik kadang-kadang terlihat. Serangan oleh parasit Babesia biasanya menyebabkan kerusаkan sel darah merah yang hebat sehingga kuda-kuda yang terserang menderita anemia hebat yang dapat menyebabkan kematian bila tidak segera diobati. Untuk mengatasi hal tersebut perlu dilakukan diagnosis yang tepat dan sedini mungkin. Diagnosis dapat dilakukan dengan cara memeriksa gejala-gejala klinik, preparat ulas darah, inokulasi hewan lain dan dengan mengadakan pemeriksaan secara serologik. Gejala-gejala klinik babesiosis pada kuda yang bersifat akut yang paling sering terlihat, ialah : nafsu makan menurun/hilang, lesu, bulu suram dan tidak mau bergerak. Kuda yang dilepaskan di padang rumput akan mengasingkan diri dan jalan sempoyongan. Faeces yang keluar berwarna cok- lat gelap, diselaputi lendir yang berwarna kekuningan dan urimenya berwarna merah tua. Temperatur tubuh meningkat menjadi 39.5 - 41°C dan pulsus meningkat. Terlihat dispnoe, perdarahan petechi pada mukosa membrana nictitans dan conjunctiva yang lebih pucat dari normal dan juga icteris. Kasus-kasus yang bersifat subakut gejala-gejalanya lebih ringan, tetapi bila tidak segera diobati maka gejala- gejala tersebut secara cepat menjadi hebat. Persendian lutut dan persendian gelang puyuh membengkak dan padanya ter- lihat oedema. Pada abdomen, dada dan kepala juga dapat di- temukan oedema. Gejala-gejala klinik yang terlihat pada kasus kronik adalah penurunan kondisi tubuh kuda secara progresif walaupun diberi makan yang banyak. Perubahan temperatur tidak jelas, nafsu makan berubah-ubah, icterus tidak jelas dan anemia mungkin hanya dapat dideteksi dengan menghitung sel darah merah dan kadar hematocrit…dst
