Abstrak: Fishing gear used by the fishermans of North Halmahera district to conduct fishing is very diverse, good for catching pelagic, demersal, and reef fish. The dominant fishing gear used by fishermen are fishing yield, multiple hand line, gill nets, etc., using a fleet of boats is simple until a boat or ship with a capacity of 10 gross tonnage. However, the use of destructive fishing gear, the environment still numerous in some areas of North Halmahera waters such as the use of bombs. The tool is dropped into the water contained a lot of fish, and causing an explosion that resulted in the death of small fish and large around the blast site. This action is performed not only in shallow waters sea, but also performed in deep waters sea. This action is very harmful to the environment and fishermen. The fish that have not been feasible arrested will die, and the risk of disability or until death can be experienced by the fishermans.

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
