Judul: Perkembangan subsektor perikanan dalam perekonomian kabupaten selayar 1993-2005
Abstrak: Secara umum kondisi kabupaten Selayar merupakan salah satu kabupaten maritim dalam wilayah negara kepulauan Republik Indonesia. Berdasarkan kondisi hidro-oseanografi dan morfogenesa, perairan kabupaten Selayar memiliki suatu keunikan sebagai kawasan perairan. Letak perairan dengan cakupan areal yang cukup luas seperti selat Makassar, laut Flores, laut Maluku dan teluk Bone memungkinkan pertukaran massa air yang berdampak optimal pada sirkulasi nutrien, menjadikan perairan ini subur dan dihuni oleh berbagai jenis ikan dengan nilai ekonomi yang tinggi.

Judul: Optimasi Perikanan Layang di Kabupaten Selayar Propinsi Sulawesi Selatan
Abstrak: Scads is a potential fishing resources in Selayar regency. The production of scads fishery landed in Selayar regency was 31.5 ton in 2006. The objectives of the research are 1) to determine priority of catching technology development for scads fish in Selayar district; 2) optimum allocation of scads fish catching unit in Selayar district; and 3) to determine development strategy of scads fishery. Survey method and direct observation was used in research methodology. Some analysis used in this research were 1) Scoring method, to determine the best of scads fishing technology pursuant to biological, tehnical, sosial, economical aspects and environmentally friendly; 2) LINDO analysis was used to determine optimum allocation in scads fish catching unit; and 3) SWOT analysis was used to determine development strategy of scads fishery. The result of this research is that the scads purse seine fishing technology become the most effective, efficient and suistainable. Optimum number allocation of scads fish catching unit used in Selayar district waters is 61 units of purse seine. The development strategy of scads fishery at Selayar district are (1) Optimizing scads fishery; (2) Operating economical oil consumption fishing unit; (3) Capital effort with low interest are available; and (4) Improvement of stakeholders and public function in fishing gear operation controlling.

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.
