Judul: Perikanan Mini Purse Seine Berbasis Rumpon Di Kabupaten Maluku Tenggara
Abstrak: Mini purse seine is one kind of fishing gear that is efficient. The problem is decrease in the number of mini purse seine since 2010. Therefore conducted research on productivity and effort of mini purse seine. This research was conducted in Sathean, Southeast Moluccas Distric. The purposes of this research are: to describe mini purse seine fisheries; to analyze the status of fisheries resources; and to calculated feasibility of mini purse seine. The methods were used in this research: technique and economical feasibility. The result showed that: the construction mini purse seine in Southeast Moluccas Distric consist of bunt, nets, buoys, ropes, sinkers, purse line, rings and selvedge. The value of Revenue-Cost Ratio is 1,16. The value of Payback period is 3,37 years and the value of Return on Investment is 29,69%. Fish Aggregating Device (FAD) is one kind of an auxiliary gear to catching fish in the shallow and the deep sea waters. The installation was to attract schooling of fish to gather arround FAD, so that fish easily to be captured. Fish Aggregating Device (FAD) is one kind of an auxiliary gear to catching fish in the shallow and the deep sea waters. The installation was to attract schooling of fish to gather arround FAD, so that fish easily to be captured. The used of FAD as auxillarry gear technically feasible because appropiate with the technical criteria of FAD.

Judul: Analysis of mini purse seine Fishery Development based on Opt imization of Small Pelagic Resources In North Maluku Province
Abstrak: The small pelagic in North Maluku is highly potential, but the utilization has been not optimum due to low productivity of mini purse seine fishery. The objectives of the research are: 1) to determine relationship between production factors and mini purse seine fishing unit production; 2) to determine optimum mini purse seine fishing unit for maximum production and economic profit level in the utilization of small pelagic resources; and 3) to determine feasibility of mini purse seine fishery in North Maluku. Survey and observation methods were used in this research. Multiple regression analysis to analyze relationship between production factors with catch of fishing unit mini purse seine, production surplus method used on fish resources stock estimation, Gordon Schaefer model to analyze fishing bio-economic condition and financial analysis to analyze business revenue and feasibility. The result from multiple regression analysis showed the technical production factors that have significant effect to the fish production are number of labor, number of fishing days, mini purse seine height and mini purse seine length, otherwise factors that have not significant effect is boat size. The result from bio-economic analysis showed that exertion level of small pelagic resources using mini purse seine is almost optimum (MEY). The optimum catch for small pelagic is 20.781,87 tons per year with the optimum effort of 36.975 trips per year or equivalent with 205 mini purse seine units. Business and financial analysis of small pelagic fishing using mini purse seine showed BEP for production value per year of Rp 68.837.032,- and production volume per year of 28,89 tons. Value of NPV is Rp 453.157.157,- with IRR value of 47.23% and Net B/C value of 2.19 (more than 1), therefore mini purse seine in North Maluku is feasible to be developed.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
