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.

Judul: Pembuatan Sel Surya Berbasis Film Ferroelektrik Barium Strontium Titanate (Ba0,5Sr0,5TiO3)
Abstrak: Growth of films Ba0,5Sr0,5TiO3 (BST) 1 M has been done with variation of annealing in hold time 8 hours, 15 hours, 22 hours, and 29 hours at constant temperature 8500C, above Si (100) substrate p-type, by using the sol-gel process method which followed with spin coating process at 3000 rpm for 30 seconds. Optics spectroscopy shows that BST film solar cells with annealing hold time 8 hours, 15 hours, and 22 hours, works effectively in wavelength ≥ 700 nm absorption range. Yet for sample with annealing hold time about 29 hours effectively absorb in ≤ 700 nm wavelength range. It obtained BST film refractive index at range 2.0 to 7.0 to wavelength range ±370-870 nm. Band gap BST film value based on annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours respectively 2.60 eV; 3.12 eV: 3.24 eV, and 2.66 eV. Electrical conductivity value which obtained, indicate that the BST film is classified as semiconductor material with conductivity order 10-5-10-4 S / cm. The result of I-V photovoltaic characterization shows the BST film potentially to be a solar cells device with efficiency according to the annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours in a row are 2.68x10-5%, 3.51x10-5%, 4.53x10-5% and 3.22x10-5%
