Judul: Analisis appraisal ekonomi perikanan purse seine di Pekalongan
Abstrak: Setiap pelaku usaha perikanan berusaha memaksimalkan keuntungan dan meminimalkan biaya per unit. Analisis appraisal merupakan analisis biaya dan pendapatan untuk melihat sejauh mana keuntungan yang diterima oleh nelayan purse seine. Penelitian ini bertujuan untuk mengetahui seberapa besar manfaat ekonomi yang diterima oleh nelayan Purse seine selama tahun 2000, mengingat pada pertengahan 1997 terjadi krisis moneter yang berlanjut menjadi krisis ekonomi yang mempengaruhi daya beli masyarakat. Selain faktor tersebut, Perairan Utara Jawa diindikasikan telah mengalami penurunan stok sumberdaya sehingga tingkat harga riil dan biaya operasianal terus meningkat. Dugaan adanya penurunan stok yang terjadi di Perairan Utara Jawa juga dapat ditunjukkan dari hasil tangkapan yang cenderung menurun selama 4 tahun terakhir. Hasil penelitian ini menunjukkan terjadinya kenaikkan harga riil ikan yang mencapai 78,76%. Dari segi penerimaan yang diperoleh hasilnya meningkat tetapi hal ini juga diiringi oleh naiknya biaya operasional karena daerah fishing ground yang semakin jauh.

Judul: Kebijakan Pungutan Hasil Perikanan (PHP): Studi Kasus Perikanan Purse Seine Pelagis Kecil di Pelabuhan Perikanan Nusantara (PPN) Pekalongan
Abstrak: Purse seine fishery in North Java coastal represent one of effort capture fishery which becoming importance for fishery society in Central Java, especially Pekalongan city. The purpose of this research is to analyze effort of occupation, value of ship productivity and fish composition, fish price standard (HPI), and volume an reward (%) of PHP towards of ship purse seine small fish pelagic. This research was studied during January to June 2006 for primary collecting data at Pekalongan Fishing Port, Central Java. Method used in this research is literature study and survey method. The result show that all purse seiner are capable to operate except for 81 GT ( 2004 & 2005) and 65 GT (2005) vessels; However and the productivity of purse seiner was decreased until 14,5 % - 60,9 % for 2004 and 2005. The standard of fish price was appropriated by Ministry Regulation and Rewards of PHP have opportunity increasing equal to 3.5 % – 4.5 %.

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.
