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: Analisis Hubungan Jaringan Komunikasi dengan Perubahan Taraf Penghidupan dan Pola Pikir dalam Pemberdayaan Pembudidaya Ikan di Kabupaten Kampar, Riau.
Abstrak: Network communication has an important role in community development activities. The success of empowerment activities, that’s know if there are change in livelihood and the mindset of the people to be better. As one of its activities is fish farmer empowerment. Based on the explain, that was done research on the communication network, change of livelihood and mindset in fish farmer empowerment in Kampar Regency, case study in Koto Mesjid Village. This research has been carried out by several phases starting from preliminary surveys to conduct an introduction and approach with some community leaders and informants in June 2012, then the first phase of the research survey was conducted in June 2013 and then continued collecting data in December 2013 to May 2014, after the continued to depth interviews in August and September 2014. The population are fish farmers. The sample determined by census to 90 respondents from members of the partners PT. Telkom. They get aid from PT Telkom by funding to capital aquaculture business of Catfish (Pangasius hypopthalmus). The first objective of this research is to describe and analyze the characteristics and perception of fish farmers to the performance of field facilitator and the received of grant production facilities in aquaculture. The result of research has showed that the Fish farmer characteristics in Koto Mesjid village are mainly in the productive age, education background in moderate level, family members in moderate, income in high, have wide pond size, have long term experience and have moderate working time. The grant of production facilities received by the fish farmers are seed of Pangasius hypopthalmus from government and grant funding to capital in aquaculture business from PT Telkom. Fish farmers perception to performance of independence and government facilitators is different. That, the independence facilitator is more active than government facilitator. The second research objective is to describe and analyze the communication network in the production and marketing of fish farmer empowerment in Koto Mesjid Village. The results of the study explained that the communication network formed in the production and marketing of aquaculture business in Koto Mesjid Village are interlock personal network. The third objective of this research is to describe and analyze the changes of livelihood and mindset in fish farmers empowerment in Koto Mesjid Village. The results showed that there has been a change in the livelihood and mindset the fish farmer in doing the aquaculture business to be better. Changes in livelihood and mindset can be seen from the changes of preparatory phase in the growth phase and almost in the development phase. The fourth research objective is to describe and analyze the relationship between characteristics of fish farmers, the perception of the performance of the marketing and production facilities with the communications network in the empowerment of fish farmers in the village of Koto Mesjid. The results of the study explained that there are significant relationship some personal characteristics of fish farmers: education, income, family member, working time and pond size to communications network of the production and marketing of aquaculture in empowerment of fish farmers in the village

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.
