Judul: Manajemen Operasi Unit Penangkapan Gillnet Millenium 30 Gt Di Ppi Karangsong, Kabupaten Indramayu
Abstrak: Tingginya jumlah unit penangkapan gillnet millenium 30 GT di PPI Karangsong mengakibatkan terjadinya persaingan antar pelaku usaha, sehingga diperlukan adanya manajemen operasi yang baik agar produktivitas dapat ditingkatkan. Tujuan dari penelitian ini yaitu menghitung produktivitas unit penangkapan gillnet millenium di PPI Karangsong, menentukan faktor yang mempengaruhi produktivitas unit penangkapan gillnet millenium di PPI Karangsong, dan mendeskripsikan manajemen operasi unit penangkapan gillnet millenium di PPI Karangsong. Perhitungan produktivitas menggunakan pendekatan rasio input/output. Berdasarkan perhitungan produktivitas, kapal 4 memiliki produktivitas tertinggi, sedangkan produktivitas terendah diperoleh kapal 2. Analisis fungsi produksi menggunakan persamaan Cobb-Douglas. Faktor-faktor produksi yang berpengaruh secara bersama-sama terhadap produktivitas yaitu jumlah trip, jumlah tenaga kerja, jumlah bahan bakar, panjang jaring dan lebar jaring. Faktor-faktor produksi yang berpengaruh secara sendiri-sendiri yaitu jumlah trip dan jumlah bahan bakar.

Judul: Optimasi Teknis Perikanan Gillnet Millenium di Desa Karangsong, Kabupaten Indramayu
Abstrak: Northern Java Sea has already know as one of the most productive sea in Indonesia. Development of PPI Karangsong, is one of Fisheries development policies of Indramayu Regency for increasing the regional economic growth. Gillnet millennium is one of the most popular fishing gear in PPI Karangsong. Fishermen in Karangsong use gillnet millennium in some variation type of technical and operation method. This study aims to determine which gillnet millennium variation type has the best optimization score. This study was held by using survey method, and the data collected by purposive sampling method. Based on the results of the study revealed that the ship that operate in the PPI Karangsong made of wood with the size of the 5 GT, 20 GT, 30 GT, 40 GT and 60 GT. .Gillnet millenium that are used by fishermen made of polyamide monofilament material, the size of the gillnet millenium that is operated on the basis of the size of the ship is all 20 pieces up to 110 pieces. The fishermen in karangsong most of the fishermen are full. The score of the function for four groups as studies object are 0,18 (< 10 GT), 2,812 (20 GT), 1,824 (30 GT), and 2,89 (> 40 GT). Production factors that influence the optimization of gillnet millennium are depth of the net, number of day of the trip, and the fishing location.

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.
