Judul: Pengelolaan perikanan karang di menui kepulauan, Kabupaten Morowali Sulawesi Tengah
Abstrak: Tujuan dari penelitian ini adalah (1) mengobservasi kondisi terumbu karang di lokasi penelitian kaitannya dengan kegiatan penangkapan ikan karang; (2) melihat keberadaan ikan karang konsumsi di lokasi penelitian; (3) menggambarkan aktivitas perikanan di lokasi penelitian; dan (4) membuat rencana strategi dan rencana program pengelolaan perikanan karang di Menui Kepulauan. Penelitian ini menggunakan metode Reef Resource Inventory (RRI) untuk menilai tutupan karang secara umum dan pengamatan terhadap ikan karang sebagai data awal. Aktivitas perikanan dianalisis dengan metode deskriptif melalui wawancara mendalam, pengisian kuesioner, serta observasi langsung di lapangan. Pembuatan rencana strategi dan rencana program beserta prioritasnya dalam pengelolaan perikanan karang dilakukan dengan menggunakan metode A-WOT yang merupakan gabungan AHP dan SWOT. Berdasarkan hasil analisis diketahui bahwa kondisi terumbu karang di lokasi penelitian dalam keadaan bagus (rata-rata tutupan karang hidup 54,50%). Keberadaan ikan karang kelompok spesies target (ikan karang konsumsi) dapat dikatakan masih dalam kondisi bagus (13 famili yang terdiri dari 32 spesies). Kegiatan pemanfaatan ikan karang oleh nelayan setempat masih dilakukan secara sederhana dengan teknologi tradisional. Strategi pengelolaan perikanan karang dilakukan dengan peningkatan kualitas sumber daya manusia di Menui Kepulauan serta membuka peluang untuk usaha maricultur dan wisata bahari.

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.
