Judul: Perilaku Ekonomi Nelayan Ikan Tuna dalam Kerangka Industrialisasi Perikanan
Abstrak: This study aimed to analyze the economic behavior of tuna fisher in fisheries industrialization. The study also aimed to examine the relationship among characteristics of respondents, fisher’s business, and external’s intervention to fisher’s economic behavior. The research used the quantitative method with qualitative method support. Overall, the economic behavior of fishers in Tambakrejo Village was quite good, such as the ability to maintain quality of the catch, the use of modern technology, the build of social relationship, and ability to employ the family members. In the test between individual characteristic and economic behavior, the most significant relationship is shown by number of family member variable. This means that the more the number of family member in fisher’s family, the economic behavior will be higher. Thus, the most significant relationship between intervention and economic behavior is capital support variable. This means that higher capital support given by external, the economic behavior will be higher. The final showed that the most significant relationship of fisher’s business characteristic is shown by business capital variable. This means that the more number of business capital will make the economic behavior getting higher.

Judul: Perilaku Ekonomi Nelayan Rajungan dalam Kerangka Industrialisasi Perikanan
Abstrak: This research is aimed to analyze the economic behavior of rajungan fisher in fisheries industrialization and to examine the relationship between individual characteristics of respondents, fisher’s business and external’s intervention to fisher’s economic behavior. The research used the quantitative method supported by the qualitative method. Overall, the economic behavior of fishers was poor, indicated by their low awareness to rajungan’s quality, traditional technology, high consumption, and ineffective allocation of labor. The result of variable test shows that few variables have a correlation with economic behavior. There is a negative correlation between age and consumption behavior. This means that the lower age of rajungan fishers, the higher consumption behavior. The positive correlation is shown by level of income with allocation of labor, which means that the higher income of rajungan fishers, the higher allocation of labor. The positive correlation is shown by level of knowledge with orientation of quality, which means that the higher knowledge of rajungan fishers, the higher orientation of quality. The correlation between fisher’s business characteristics and external’s intervention is significantly high.

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.
