Judul: Social Security System Masyarakat Nelayan (Kasus Masyarakat Nelayan Ujung Kulon, Kabupaten Pandeglang, Banten).
Abstrak: Secara historis transformasi masyarakat nelayan Ujung Kulon dimulai dengan terbukanya isolasi wilayah pesisir Ujung Kulon pada tahun 1970-an dan menjadi semakin pesat di era 1980-an sampai saat ini. Lancarnya transportasi dan akses keluar masuk wilayah mendorong penetrasi kapitalisme dan pengaruh pasar semakin merasuk dalam kehidupan masyarakat. Penetrasi kapitalisme menyebabkan perubahan signifikan dalam dimensi budaya, institusi dan tindakan ekonomi. Perubahan-perubahan tersebut terkait dengan berubahnya mekanisme social security system dalam sistem penghidupan nelayan setempat. Perubahan dimensi budaya ekonomi masyarakat terjadi sebagai akibat dari terbukanya wilayah dan masuknya sistem ekonomi kapitalis yang membawa masuk barang-barang baru, gaya hidup baru dan informasi-informasi baru serta kepuasan-kepuasan baru dimana kekayaan dan konsumsi merupakan bentuk kebutuhan baru yang harus dipenuhi oleh masyarakat. Norma budaya kapitalisme seperti selfish (mementingkan diri sendiri), memaksimumkan keuntungan dan kepuasan, individualisme, serta kompleksitas pasar mempengaruhi dan mengubah budaya ekonomi masyarakat nelayan setempat. Perkembangan budaya ekonomi ini ditunjang oleh berkembangnya prasarana dan sarana transportasi dan komunikasi seperti televisi, handphone, internet dan sebagainya. Beberapa aspek tertentu dalam budaya ekonomi nelayan yang erat kaitannya dengan mekanisme perekonomian masyarakat yang mengalami perubahan antara lain orientasi bekerja keras, pandangan dan pengambilan keputusan investasi dan saving, basis resiprositas sistem trust (kepercayaan) antar pelaku ekonomi, kolektivitas ekonomi dan solidaritas. Dalam konteks perubahan budaya ekonomi masyarakat nelayan, bahwa ada aspek-aspek tertentu dalam budaya nelayan yang berubah ternyata dapat menjadi motivasi ekonomi yang diperlukan untuk pertumbuhan ekonomi pasar. Salah satu aspek budaya asli nelayan yang cenderung bekerja keras merupakan salah satu motivasi ekonomi yang diperlukan untuk pertumbuhan ekonomi pasar. Nelayan Ujung Kulon mengalami perubahan orientasi nilai bekerja keras yang semula ditujukan pada pemenuhan subsistensi berubah menjadi bertujuan mengejar kekayaan dan konsumsi. Perubahan orientasi ini justru memiliki fungsi menggerakan roda perekonomian di sektor perikanan. Orientasi bekerja keras semakin kuat ketika tujuannya mengejar kekayaan dan konsumsi yang juga berarti mencapai kemuliaan dalam masyarakat. Situasi ini akan menuntut semangat bekerja untuk mengejar keuntungan ekonomi sebanyak-banyaknya. Semangat bekerja untuk mengejar keuntungan ekonomi didukung oleh meningkatnya kepercayaan diri untuk berinvestasi dan saving yang didasari oleh optimisme dengan risiko kerugian dapat menjadi pendorong bagi pertumbuhan ekonomi nelayan. Di sisi yang berbeda introduksi norma budaya ekonomi kapitalis ternyata justru melemahkan mekanisme social security system tradisional masyarakat nelayan setempat oleh karena perubahan sistem norma yang mendasari resiprositas, trust, kolektivitas dan solidaritas yang semula menjadi basis nilai utama dari mekanisme social security system tradisional yang memberikan jaminan social economic security bagi masyarakat nelayan. Dari dimensi perubahan institusi, penetrasi sistem ekonomi kapitalis membawa perubahan signifikan dalam institusi patronase yang merupakan social security institution yang keberadaannya sangat signifikan dalam perekonomian nelayan. Terjadi transformasi basis norma institusi patronase berbasis norma tradisional (moralitas asli) menjadi berbasis norma ekonomi kapitalis di masa kini. Implikasi perubahan basis norma terjadi pada aktivitas ekonomi pertukaran dan transaksi ekonomi serta dasar pengambilan keputusan seluruh pelaku-pelaku ekonomi. Ketika institusi ekonomi patronase berbasis norma moralitas asli, maka strategi tindakan ekonomi survival terlekat pada institusi patronase yang sepenuhnya berfungi sebagai social security institution. Tindakan ekonomi survival terwujud pada seberapa jauh nelayan dapat membangun hubungan patronase yang dapat memberikan jaminan pemenuhan kebutuhan subsistensi dan hubungan saling menguntungkan dengan basis etika moralitas. Ketika basis norma patronase berubah,

The implication of change in norm base occurred

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.
