Judul: Analisis Pendapatan dan Efisiensi Produksi Usahatani Budidaya Pembesaran Ikan Mas dan Nila Pada Keramba Jaring Apung Ganda (Studi Kasus Waduk Cirata Desa Bobojong Kecamatan Mande Kabupaten Cianjur)
Abstrak: Cirata reservoir is one of three reservoirs in Citarum River that has major contribution to the fisheries in West Java. Fisheries in Cirata is conducted by fish rearing (Keramba cage) double KJA. Aquaculture of KJA performed by enlargement Cyprinus carpio and tilapia. This is because those commodities were major commodities in Cirata especially Cyprinus carpio. Enlargement of Cyprinus carpio and tilapia Aquaculture was cultivated widely in Bobojong village. The Objective of this research were to identify the structure of costs and farm income from KJA enlargement of Cyprinus carpio and tilapia aquaculturein Bobojong village by using π=TR-TC method, to analyze the factors that affect farm income from enlargement of Cyprinus carpio and tilapia aquaculture in Bobojong Village by using multiple linear regressi on analysis, to analyze the efficiency of production by using MR = MC and revenue efficiency y R/C method. Based on there gressi on results obtained, the factors that affect farmers' income significantly on the 5% through significance level were the number of Cyprinus carpio production, total production of tilapia, Cyprinus carpio seed costs, the price of tilapia seed, and the price of Cyprinus carpio feed education were not affected largely for the farm income. The results obtained on the third objectives howed that production off arming aquaculture on KJA fisheries was not optimal so that the production and production inputs used need to be optimized in order to get maximum profit. Enlargement of Cyprinus carpio aquaculture and tilapia in Bobojong Village was feasible to performed because the value of R/C off farm income from cash costs and total cost was greater than one.

Judul: Analisis faktor produksi dan pengembangan usaha budidaya Ikan Mas (Cyprinus carpio) dalam jaring apung di Waduk Cirata Desa Cikidang Bayaban, Kecamatan Mande, Kabupaten Cianjur, Jawa Barat
Abstrak: Produksi ikan mas dari usaha budidaya jaring apung di Waduk Cirata dari tahun ke tahun mengalami peningkatan seiring dengan pertambahan jumlah kolam jaring apung yang diusahakan. Pada satu tahun terakhir 1994-1995 produk- tivitas ikan mas dari usaha jaring apung cenderung menga- lami penurunan. Berhubungan dengan hal tersebut maka untuk mendapatkan manfaat yang lebih besar dalam usaha budidaya jaring apung diperlukan penyusunan perencanaan dan kebijakan dalam pengelolaannya. Salah satu pengelo- laan ini adalah aspek manajemen produksi yaitu dengan cara mengalokasikan input-input secara tepat sebagai salah satu usaha untuk mendapat produksi yang optimum dengan keun- tungan maksimum atau disebut efisiensi usaha. Sedangkan untuk melihat prospek pengembangan usaha jaring apung dimasa akan datang di waduk Cirata dilakukan analisis finansial. Tujuan dari penelitian ini adalah (1) Mengetahui alokasi penggunaan faktor produksi usaha jaring apung di daerah penelitian (2) Mencari kombinasi penggunaan faktor produksi yang paling tepat (3) Melakukan kajian pengem- bangan usaha melalui analisis finansial. Sedangkan kegu- naan dari penelitian ini adalah: (1) Bagi mahasiswa seba- gai latihan di lapangan dan sebagai salah satu syarat ...

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.
