Judul: Hubungan Karakteristik Individu dan Perilaku Komunikasi dengan Tingkat Adopsi Teknik Pencegahan Kematian ikan (Kasus Petani Ikan Jaring Apung di Blok Jangari Waduk Cirata Cianjur).
Abstrak: The objective of the research is to study the relationship between individual characteristics and communication behavior with the level of adopted technique in preventing fish death. The subjects in this research are fish farmers operating floating nets at Blok Jangari Waduk Cirata, Cianjur. The death of fish occurred several times in the area due to plankton booming, recurrent wave, or herpes disease of fish. Some experienced farmers have the knowledge to predict, identify, and overcome the above mentioned problems. Accordingly some preventive measures have been regularly practiced. However, the problems still exist that costs farmers hundreds of tons of fish yearly. It was presumed that effective communications between farmers and extension agents, among farmers, and between farmers and other elements in the business would overcome the problems. The research was conducted in April 2006 using 50 responders. Measurement instrument was tested for validity and reliability before use. Data were analyzed using “Rank Spearman correlation test”. The result shows that the prevention of fish death is effective for most farmers but some farmers do not have the capacity to do so. Most information gathered by farmer, regardless the preventive technique, is through interpersonal communication with the buyers which also serve as middle man in the fish business. Communication through radio or mass media is less important in this case.

Abstrak: Akuakultur adalah suatu kegiatan memelihara, memelihara, membudidayakan, dan memanen ikan lingkungan yang terkendali. Kegiatan yang dilakukan oleh petani ikan, komunikasi Jaringan ini penting karena berkontribusi dalam pengembangan budidaya perikanan Misalnya, informasi pasar. Tujuan dari penelitian ini adalah untuk menganalisis komunikasi jaringan pada petani ikan, mengidentifikasi hubungan individu karakteristik dan perilaku pemasaran dengan komunikasi jaringan (individu gelar koneksi). Penelitian ini menggunakan metode survei eksplanatori tujuan, yang dipadukan dengan pendekatan penelitian kuantitatif dan diperkuat oleh pendekatan penelitian kualitatif. Instrumen penelitian ini adalah kuesioner untuk data kuantitatif dan wawancara mendalam untuk data kualitatif. Jaringan komunikasi dapat membantu para petani ikan untuk berinteraksi dengan berbagai pihak mengenai pemasaran sehingga dapat membantu para peternak ikan dalam mengembangkan usahanya.

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.
