Judul: Efektivitas Komunikasi Program Optimalisasi Lahan Pekarangan (Kasus Program Kawasan Rumah Pangan Lestari di Desa Mulyasari Kecamatan Ciampel Karawang Jawa Barat)
Abstrak: For change and renewal in society, effectiveness communications is needed so as to produce a change in the rate of cognitive, affective, and conative. In the Sustainable Food Home Area (KRPL) program, effectiveness communications is absolutely essential for their future as a program participant is able to adopt and implement the optimalization of their backyards so as not to let it alone. The purpose of this study were to (1) analyze the effectiveness communications KRPL program in the Mulyasari Village Ciampel District Karawang of West Java, (2) analyze the relationship between individual characteristics variable and external factors variable to the effectiveness communications variable of KRPL program in the Mulyasari Village Ciampel District Karawang of West Java, and (3) analyze the relationship between the effectiveness communications variable of KRPL program with the optimalization of backyard variable in the Mulyasari Village Ciampel District Karawang of West Java. The study were designed to use quantitative survey methods explanation research. These results indicate that (1) KRPL program conducted in the Mulyasari Village District Ciampel Karawang of West Java is quite effective at the level of cognitive, affective, and conative. It is evident that most participants KRPL program can understand the information they get from the instructor of the program, they also want to implement this optimalization program of their backyards, and they also run the program from The Ministry of Agriculture in optimize their yards that they have, (2) individual characteristics significantly and positively related to the effectiveness communication is an indicator of education and yard area. The external factor significantly and positively related to the effectiveness communication is an access to information, public policy, and the illumination intensity, and (3) effectiveness communications (cognitive, affective, conative) of KRPL program significantly and positively related to optimalization of their utilization backyards.

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.
