Judul: Sumberdaya udang penaeid dan prospek pengembangannya di Kabupaten Sorong Selatan Propinsi Irian Jaya Barat
Abstrak: The South Sorong Regency is a new regency based on the Government Rules No : 26/2002 as a consequence of Sorong Regency expansion. The dominating fishery in this area is shrimps. However, it has not been fully optimized (Fishery Academic Sorong, 2004). The objectives of this study are : (1) To estimate the maximum sustainable yield. (2) To calculate the fishing effort feasibility. (3) To decide the optimum number of fishing unit. (4) To arrange the strategy of sustainable development policy. Swept area method, analysis of effort feasibility, linear goal programming and analytical hierarchy process were used to solve the problem. The result of research show that sustainable stock of penaeid shrimps based on the result analysis, can be concluded that is 12.778,174 ton/year. Shrimp fisheries in South Sorong Regency potential to be developed. To develop shrimp fisheries, the result analysis suggest allocation of fishing gear as below: number of vessel are approximately ketinting (219 units), jolor (217 units), johnson (25 units) and pkp (20 units). The alternative of strategy policy organized by priority as follow : capacity building to fisherman and cooperation with actor, to developed the fishing unit which sustainable of environment, to improve the penaeid shrimps productions, to improve facility and equipments, and to improve the market potency.

Judul: Kemungkinan pengembangan perikanan cakalang di Sorong, Irian Jaya
Abstrak: Sumberdaya ikan tuna/cakalang masih merupakan andalan ekspor perikanan Indonesia, setelah udang. Nilai sumberdaya ini akan semakin besar seiring dengan semakin berkembangnya aktivitas pemanfaatan sumberdaya ini. Disadari bahwa peningkatan kualitas maupun kuantitas upaya penangkapan di suatu perairan selain akan semakin meningkatkan nilai ekonomi dari sumberdaya tersebut terhadap kesejahteraan masyarakat, khususnya masyarakat nelayan serta meningkatkan pendapatan pengusaha perikanan, juga diharapkan akan tetap mempertahankan suatu tingkat pengusahaan yang rasional yang berkesinambungan dimana sumberdaya tersebut tetap lestari. Oleh karena itu, kajian terhadap kondisi sistem perikanan yang sudah ada perlu dilakukan, guna mendapatkan suatu bentuk sistem pemanfaatan yang efisien dan efektif secara teknis-ekonomis dan tetap mempertimbangkan kelestarian sumberdaya.

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
