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: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
