Abstrak: Farmer’s group is one of agribusiness institution, which is located in the region of the countryside. This institution is expected plays an important role in every farming activity. However, there are still many farmers groups that do not run according to the function. This research aims at analysing the performance of the Karya Mekar Farmers Group and the influence of the institution against the success of mangosteen farming on farmer members in Karacak Village Leuwiliang. The result of this research showed that Karya Mekar Farmers Group had not been running optimally yet. This because there were things that didn’t suit well such as things that related to market existence and credit system on farmers’ group that didn’t work well yet. Karya Mekar Farmers Group also played the role in the success of farming on its members. This could be seen from the result of farming income and the R/C ratio which higher than non-group farmers

Abstrak: The presence of farmers institution could be the key to improve welfare and economies of scale in the village for farmers. As its function, farmers institution could be a forum of farmers for improving quality, quantity, and continuity of their crops togetherness. Farmers institution also could be balancing the bargaining position between small farmers and marketing farmers then food estates. This research aims to assess the performance of farmers institution in Mekarmukti Village, Cibinong District, Cianjur, West Java in farmers group level as a forum of farmers and Farmers Group Associaton (FGA) level which could be improving the economies of scale and act as supporting institutions other agribusiness subsystem in agribusiness system of chili. This research also measured an impact from FGA and farmers group to farmers so that establish a hierarchy system which synergize for farmer’s welfare. Performance analysis measured with descriptive statistical analysis and impact analysis measured with nonparametical statistic, Wilcoxon Paired Test. Result, Mekarmukti FGA have a success rate performance of 72,73 percent and farmers group in associated with it have rate in the range below. Mekarmukti FGA also impact positively in 17 variabels from 23 tested variabels. In conclusion, FGA and farmers group in associated with are important for member farmers because of have a good performance and and positive impact. However, Mekarmukti FGA and farmers group in associated with still have to improve the performance which not optimally yet and reducting the negative impact.

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.
