Judul: Kajian model gugus pulau dalam pengembangan Wilayah Kepulauan di Kabupaten Maluku Tenggara Barat, Provinsi Maluku
Abstrak: The size of the small island and the isolated location by the sea are related to the limited supply of the land resources and the accessibility to the surrounding islands. The problem of the small islands are generally related to the difficulties to get the supply for living and various facilities needed for development, coming from inside and from outside of the small islands. To solve the problem, it needed a spatial approach model, and one of the approach model is island cluster model. The design of this model focus to the effort of the levelization of the population in order to reach the balance between Ecological Footprint (EF) and Bio Capacity (BC), by the interaction proses among the islands in the research area. Based on the design on the model mention above the aim of this study is to know the implication of the island cluster model in the development of the archipelago in Western part of Southeast Maluku Regency, which stratified in macro, messo, and micro level. The results shows that in macro level, the mechanism of the islands cluster model can reduce the gap of GDP growth, in messo level can reduce the un employment, and in micro level can extend the sustainability length of time of each small islands in the study area.

Judul: Study of the Islands Cluster Model, for the development of archipelago of the Western Southeast Maluku Regency, of Maluku Province.
Abstrak: Luas wilayah Kabupaten Maluku Tenggara Barat (MTB) secara keseluruhan mencapai 125.422,4 Km2. dari luas tersebut 110.838,3 Km2 atau 88,37% diantaranya merupakan wilayah lautan. Sedangkan 14.584 Km2 atau 11,63% sisanya merupakan wilayah daratan yang terfragmentasi dalam bentuk pulau dan pulau kecil dengan luas dibawah 2.000 Km2. Dengan demikian secara geografis wilayah Kabupaten Maluku Tenggara Barat didominasi oleh pulau-pulau kecil, bahkan sangat kecil, sehingga karakteristik pulau-pulau kecil sangat berperan dalam pengembangan wilayahnya. Dengan luasan wilayah yang kecil, maka pulau-pulau kecil memiliki keterbatasan dalam ketersediaan sumberdaya alam dan jasa-jasa lingkungan seperti air tawar, vegetasi, tanah, ekosistem pesisir dan satwa liar , sehingga pada gilirannya akan berpengaruh terhadap daya dukung pulau-pulau kecil tersebut didalam menopang kehidupan manusia serta segenap kegiatan pembangunan yang ada. Dengan semakin banyaknya penduduk di pulau-pulau kecil, maka kebutuhan penduduk akan lahan di pulau kecil juga semakin meningkat. Jika kebutuhan ini tidak sesuai dengan kapasitas daya dukung lahan yang cukup memadai dari waktu ke waktu, maka keberlanjutan pembangunan pulau-pulau kecil tidak akan tercapai. Selain kecil, tata letak dari pulau kecil dalam ruang yang terpisah oleh laut dan lautan cenderung terpencil sehingga aksesabiltas dari lingkungan diluar pulau kecil tersebut yang diharapkan dapat ikut memberikan suplai kebutuhan hidup serta berbagai fasilitas lainnya didalam rangka mendukung proses pertumbuhan dari pulau kecil tersebut juga relatif lebih sulit.

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.
