Judul: Performance of “Jeriken Fishing line” in Pasar Kota Krui  Vilage, West Coast Regency of Lampung
Abstrak: Pancing jeriken disebut PJ merupakan jenis alat tangkap pancing ulur yang digunakan nelayan Pasar Kota Krui sebagai alat tangkap utama untuk menangkap ikan marlin dan ikan tuna. Informasi mengenai pancing jeriken di daerah tersebut belum cukup dalam aspek keragaannya. Penelitian mengenai keragaan alat tangkap pancing jeriken dapat dijadikan sebagai informasi dasar bagi pemerintah daerah dalam melakukan pengelolaan perikanan pesisir khususnya untuk perikanan pancing jeriken. Tujuan dari penelitian ini adalah untuk mendeskripsikan keragaan unit alat tangkap pancing jeriken, mengetahui komposisi hasil tangkapan dan menghitung kelayakan ekonomi perikanan pancing jeriken di Pasar Kota Krui. Pengumpulan data dilakukan dengan metode studi literatur, wawancara dan observasi dengan mengikuti trip operasi penangkapan ikan. Hasil penelitian menunjukan bahwa alat tangkap pancing jeriken yang digunakan memiliki dua ukuran, yaitu jerigen ukuran 5 L dan jerigen ukuran 10 L dengan daerah pengoperasian sejauh 1-25 mil. Nelayan motor tempel memiliki rata-rata hasil tangkapan sebesar 2.479 kg/tahun, lebih banyak dibandingkan dengan nelayan ketinting. Selain itu, ikan tuna memiliki rata-rata jumlah hasil tangkapan sebesar 1.376 kg/tahun. lebih banyak dibandingkan ikan marlin Analisis usaha pancing jeriken nelayan ketinting dikatakan lebih menguntungkan dibandingkan nelayan motor tempel., "Jeriken fishing line" or called PJ is a type of hand line fishing gear used by fishermen at Pasar Kota Krui as the main fishing gear to catch marlin and tuna. Information of the PJ in that area does not have sufficient data regarding its technical and economic performance aspects. Research on PJ's performance can be used as basic information for local governments to develop coastal fisheries management. The study aims to describe the technical performance, catch composition, and financial analysis of the jeriken fishing line at Pasar Kota Krui. Data was collected using literature study, interviews, and direct observations by following the fishing operations. The results showed that the fishing gear used has two sizes was 5 L and 10 L with a fishing ground of 1-25 miles. The average catch of outboard boats was 2,479 kg/year, which was higer than the catch of catamaran boats. Tuna catch was 1.376 kg/year, catch was higher than marlin. Based on financial analysis PJ using a catamaran was more profitable than an outboard boat.

Judul: Characteristics of Crab Gillnet and Bottom Gillnet at Karangantu Fishing port, Banten
Abstrak: Kegiatan penangkapan ikan dilakukan berdasarkan cuaca sehingga pendapatan yang diterima oleh nelayan tidak menentu sehingga terdapat hari-hari dimana nelayan tidak memiliki penghasilan. Penelitian ini dilakukan untuk mengidentifikasi sistem bagi hasil antara nelayan penggarap dengan nelayan pemilik, dengan terlebih dahulu mengidentifikasi kondisi eksisting nelayan penggarap yang termasuk nelayan kecil (≤5GT) terkait dengan dimensi kapal, biaya operasional dan pendapatan. Berdasarkan hasil penelitian diketahui desain kapal jaring rampus dan rajungan memiliki perbedaan bentuk dimana kapal jaring rajungan berbentuk double pointed, sedangkan kapal jaring rampus berbentuk transom. Sitem bagi hasil antara pemilik kapal dan nelayan untuk unit penangkapan ikan jaring rajungan dan jaring rampus di PPN karangantu adalah sama. Hasil penjualan hasil tangkapan tiap trip setengah bagian diberikan kepada pemilik kapal setengah bagian lagi dikurangi baiaya operasional yang telah dikeluarkan trip oleh pemilik kapal kemudian dibagi jumlah ABK kapal, Fishing activities are carried out based on the weather so that the income received by fishermen is uncertain, there are days when fishermen do not have income because they cant go fishing. This research was conducted to identify a profit sharing system between tenant fishermen and owner fishermen, by first identifying the existing conditions of working fishermen, including small fishermen (≤5GT) related to ship dimensions, operating costs and income. Based on the research results, it is known that the design of Bottom Gillnet and Crab Gillnet has different shapes where the crab gillnet have double pointed shaped, while the bottom gillnet are transom shaped. The profit sharing system between boat owners and fishermen for small crab gillnet and bottom gillnet fisheries at PPN Karangantu is the same. Where the proceeds from the sale of the catch for each half part trip are given to the owner of the ship for the other half minus the operational costs that have been incurred by the trip by the ship owner then divided by the number of crew.

Judul: Penyusunan Overlap Graph menggunakan Suffix Tree pada DNA Sequence
Abstrak: The DNA sequence assembly is very important in genome analysis. This step aims to reconstruct contigous DNA fragment (contigs) from short fragment by concatenating fragments based on the overlap region among them. This method employs overlap graph for solving the problems. In this graph, nodes represent fragments and edges represent overlap. This research developed a software for constructing overlap graph using suffix tree. The evaluation was conducted by measuring the number of nodes, number of edges, and the execution time in many values of minimum overlap. The minimum overlap is defined as the minimum length of substring which is considered as the overlap region between two fragments. The evaluation results showed that the number of nodes, the number of edges, and the execution time were increased with the decreasing of the minimum overlap value.
