Abstrak: his research is executed from Februari until April 2004 in South Halmahera arch Regency, Research Target is to ; (I) Studying Exploiting Resources Isle pass through Determination Condition and Potency of According To the Exploiting Resources Isle Allotment, (2) Striving Subdistrict and countryside Development in South Halmahera arch Regency region, (3) Determining Regional Development policy direction of Coastal area in South Halmahera arch Regency. According To exploiting Allotment Resources of Coastal area in South Halmahera arch Regency analysed with Analysis Spasial with method Overlay. Analyse centers Bases activity (pre-eminent.) conducted by using method Location Quotient Analisys (LQ), Analyse Excellence Kompetitif conducted by using method Shift Share Analisys, Analyse countryside development conducted by using method Principle Component Analisys and also Analyse Group (Cluster Analisys). Result obtained is; according to Farm KJA Allotment in Bacan East, B. West, and Kayoa, allotment cultivation Pearl in]Subdistrict Bacan East, Coastal Tourism Allotment in 6 subdistrict in Regency region Halmahera of South arch of except Bacan and Bacan West East, while Fisherman Settlement Allotment in meeting Subdistrict Bacan, Concentration Sekot Bases in Agricultural Sector met at Subdistrict Bacan and Gane East from type tubers, while for subdistrict Kayoa met by type Jambu mete, and nutmeg in Paling Island subdistrict, whereas fishery sector met in subdistrict Gane West namely the fish laying type. excellence Kompetitif of each dross look seen by where at subdistrict Bacan West, Bacan East, and Bacan show good economics growth at the same time with farm exploiting competition height of tubers. Where high competition enough at arrest activity in subdistrict Kayoa, Gane East, Gane West Paling Island and happened by degradation haul. At appliance exploiting catch good enough at subdistrict Kayoa of whereas 8 subdistrict in region Halmahera of South arch of showed of the happening of very drastic degradation. Dati of Result of Analisistiponomi countryside is fisherman of where sill tendency to the sea being based on society. Result of group Analysis in discovering 2 countryside group that is; there is and also the countryside group which is relative left behind and insulated. Conclusion obtained by that is countryside in region Halmahera ofSouth arch enable for the coastal allotment, and settlement fisherment; Small Exploiting Pulai not yet optimal so that development of fishery sector relative minimize, discovered by the optimal group so that development of fishery sector relative minimize, discovered by the new countryside group expand and the countryside which isrelative left behind and insulated.

Judul: igenvalues and Eigenvectors of Tridiagonal Matrix with Non Constant and Recurrent Diagonal Entries.
Abstrak: Matriks tridiagonal adalah suatu matriks yang mempunyai entri-entri bernilai nol kecuali pada diagonal utama, di bawah diagonal utama (subdiagonal) dan di atas diagonal utama (superdiagonal). Entri pada diagonal utama tidak konstan dan berulang. Setiap entri pada matriks tridiagonal ini adalah bilangan kompleks. Dalam karya ilmiah ini, akan dibuktikan 3 teorema untuk menentukan nilai eigen dengan 2 kasus dan 1 teorema untuk menentukan vektor eigen. Teorema pertama menentukan polinomial karakteristik dari matriks tridiagonal. Polinomial karakteristik dari matriks tridiagonal tersebut digunakan untuk menentukan nilai eigen pada teorema kedua dan ketiga serta menentukan vektor eigen pada teorema keempat
