Judul: Kajian Pengembangan Wilayah Pulau-Pulau Kecil Di Kabupaten Halmahera Utara (Tinjauan terhadap Pengelolaan Sumber Daya Perikanan Cakalang)
Abstrak: Pelaksanaan pembangunan yang berorientasi pada wilayah daratan mengakibatkan wilayah pulau-pulau kecil mengalami ketertinggalan sehingga pemanfaatan sumber daya alam yang tersedia di wilayah tersebut belum optimal. Penelitian ini bertujuan untuk menganalisis sub sektor mana yang memiliki keunggulan komparatif dan kompetitif, menentukan pusat pelayanan fasilitas perikanan cakalang, menganalisis pemanfaatan sumberdaya perikanan cakalang dan pola kelembagaannya. Metode analisis yang digunakan adalah location quotient (LQ), shift- share (SSA), skalogram, bioekonomi dan deskriptif. Hasil penelitian menunjukkan bahwa sub sektor yang mempunyai keunggulan komparatif dan kompetitif tinggi adalah sub sektor kehutanan, sedangkan sub sektor perikanan mempunyai keunggulan komparatif tetapi mempunyai daya saing yang kecil. Pusat pelayanan fasilitas perikanan cakalang yang terbesar terdapat di Desa Daruba Kecamatan Morotai Selatan. Pemanfaatan sumberdaya perikanan cakalang belum optimal. Pola kelembagaan perikanan cakalang belum berkembang dengan baik, antar unsur lembaga belum berinteraksi secara sinergis.

Judul: Kajian pemanfaatan dan pengembangan sumberdaya pulau kecil di Kabupaten Halmahera Selatan
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: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
