Judul: The Dynamics of Bouke Ami Fishery in Muara Angke Fishing Port
Abstrak: Operasi penangkapan bouke ami membutuhkan modal untuk berlayar yang cukup besar dan dapat menyebabkan kerugian jika pendapatan dari hasil tangkapan lebih kecil dari modal yang dikeluarkan. Perencanaan penangkapan ikan yang di susun berdasarkan dinamika usaha perikanan dapat mengurangi resiko terjadinya kerugian tersebut. Penelitian ini bertujuan untuk mengidentifikasi dinamika usaha penangkapan kapal bouke ami di Pelabuhan Perikanan Nusantara (PPN) Muara Angke sebagai bahan perumusan perencanaan penangkapan ikan. Dinamika tahunan kapal bouke ami di PPN Muara Angke dilihat berdasarkan data hasil tangkapan per trip, jumlah trip per bulan, jumlah pembelian solar subsidi per kapal, dan harga hasil tangkapan terhadap kondisi cuaca di daerah penangkapan. Hasil penelitian menunjukkan periode dengan hasil tangkapan per trip kapal bouke ami tertinggi berada pada periode Oktober-Desember. Pola keberangkatan kapal bouke ami di PPN Muara Angke terjadi pada dua periode, periode pertama pada bulan Februari-Mei dan periode kedua pada bulan Juli-Oktober. Harga tangkapan nelayan bouke ami yang didaratkan di PPN Muara Angke relatif stabil pada saat kondisi cuaca buruk. Kelimpahan hasil tangkapan bouke ami dipengaruhi secara signifikan oleh cuaca namun operasi penangkapan kapal bouke ami tidak signifikan dipengaruhi oleh cuaca karena kondisi daerah penangkapan yang stabil saat kondisi cuaca buruk, Bouke ami fishing operations require considerable operational expenditure and can result in losses if income does not exceed the expenditure. Planning a fishing operation based on its dynamics can reduce the risk of such losses. This study aims to identify the dynamics of bouke ami fishing operation at Muara Angke fishing port as a basis for formulating fishing plan. The research identifies annual dynamics of bouke ami boats in Muara Angke fishing port against weather conditions in the fishing ground on the subject of catch per trip, trip total per month, the subsidized diesel purchases per ship, and catch prices. The results show that the period with highest catch per trip of bouke ami boats is in October-December. The departure pattern of bouke ami boats at Muara Angke occurs in two periods, the first period in February-May and the second period in July-October. The price of bouke ami fishermen's catch landed at Muara Angke fishing port is relatively stable during bad weather. The abundance of bouke ami catch is significantly influenced by the weather but fishing operation is not significantly influenced by the weather since fishing ground condition are stable in bad weather period.

Judul: The Effect of Rising Fuel Prices on the Fisherman's Income of Bouke Ami at Muara Angke Fishing Port
Abstrak: Nelayan bouke ami membutuhkan biaya operasional untuk melaut, salah satu diantaranya adalah bahan bakar minyak (BBM). Kenaikan harga bahan bakar minyak membuat nelayan bouke ami kesulitan melaut. Penelitian ini bertujuan untuk mengidentifikasikan kondisi umum perikanan bouke ami ukuran kapal =30 GT di PPN Muara Angke Jakarta, menghitung perbedaan biaya operasional unit penangkapan bouke ami =30 GT sebelum dan sesudah kenaikan harga BBM, dan menghitung perbedaan pendapatan dan keuntungan kapal bouke ami =30 GT sebelum dan sesudah kenaikan harga BBM di PPN Muara Angke Jakarta. Penelitian dilaksanakan di PPN Muara Angke dan menggunakan metode survei dengan teknik observasi langsung terhadap kapal bouke ami =30 GT. Hasil penelitian ini menunjukkan bahwa unit penangkapan bouke ami di PPN Muara Angke didominasi oleh kapal berukuran =30 GT sebesar 92%. Kebutuhan biaya operasional naik sebesar 43% antara sebelum dan sesudah kenaikan harga BBM, dan terdapat pengaruh dari kenaikan harga BBM terhadap pendapatan dan keuntungan nelayan di PPN Muara Angke., Bouke ami fishermen need operational cost to go to sea, one of them is fuel oil. The increase in fuel prices has made it difficult for bouke ami fishermen to go to sea. This research aims to identify the general condition of the current bouke ami ship size =30 GT fishery at PPN Muara Angke Jakarta, count the operational costs of fishing units for bouke ami =30 GT before and after the increase in fuel prices, and count the difference in income and profits of bouke ami vessels =30 GT before and after the increase in fuel prices at Muara Angke port. The research was carried out at PPN Muara Angke and used a survey method with direct observation techniques on bouke ami vessels =30 GT. The results of this research show that the bouke ami fishing unit at Muara Angke port is dominated by vessels measuring =30 GT by 92%. The need for operational costs increased by 43% between before and after the increase in fuel prices. There is a significant effect of the increase in fuel prices on fishermen’s income at Muara Angke port.

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.
