Judul: Utilization Analysis of The Mackerel (Rastrelliger spp) Resources in Tanah Laut District South Kalimantan Province
Abstrak: Tanah Laut is a district in South Kalimantan Province which has potential mackerel (Rastrelliger spp) resources. The objectives of the research were (I) to estimate level utilization of in the mackerels at Tanah Laut District, (2) to determine the appropriate fishing technology for catching mackerels around in Tanah Laut District, (3) to develop a strategy for mackerel fisheries in Tanah Laut District. Research activities which had been done included fishing gear analysis, stock analysis, financial analysis, scoring method and SWOT analysis. The utilization level of mackerel resources had achieved 77%. The purse seine fishery is more technologically appropriate and beneficial than the encircling gillnet fishery. The development strategies of the mackerel fisheries are (1) optimum utilization of the mackerel resouces, (2) development of mackerel fisheries to be more efficient and effective, (3) improvement of fisheries infrastructures and facilities, (4) improvement of government role and public participation in monitoring, controlling and surveilance of the mackerel resources.

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: Grup Abelian Berhingga dari Barisan Genomik DNA  (Deoxyribonucleic Acid)
Abstrak: Informasi genetik yang memprogram semua aktivitas sel terdapat dalam bentuk kode di dalam molekul DNA. Grup kodon dari basa nukleotida DNA {A, C, G, U} tidak dapat merepresentasikan daerah non kode dalam genom yang disebabkan oleh mutasi penghapusan serta penyisipan pada barisan genomik DNA. Dalam karya ilmiah ini grup kodon diperluas dengan menambahkan huruf O untuk menandakan mutasi penghapusan atau penyisipan pada kodon untuk semua triplet diperluas 1 2 3 X X X dengan i X Î{O, A, C, G, U} dari barisan genomik DNA. Grup kodon yang diperluas isomorfik dengan grup bilangan bulat modulo 125. Grup abelian berhingga dari barisan genomik DNA yang dibentuk dari himpunan seluruh pasangan terurut triplet ekson dan intron pada untai DNA isomorfik dengan grup jumlah langsung bilangan bulat modulo 64 dan 125. Kemudian grup abelian berhingga tersebut direpresentasikan sebagai grup jumlah langsung 2-grup dan 5-grup homosiklik. Bagian barisan genomik DNA tanpa penyisipan membangun blok gen yang direpresentasikan oleh 2-grup homosiklik, sedangkan bagian barisan genomik DNA yang dipengaruhi oleh penyisipan direpresentasikan oleh 5-grup homosiklik.
