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: Mangosteen is a fruit tree crop that comes from a shady tropical forests in Southeast Asia. Mostly comes from Malaysian and Indonesian jungle. Mangosteen fruits one of Indonesia'sleading commodities for agribussiness. And therefore mangosteen have the potential to be exported to foreign countries. But the limitations of mangosteen farmers towards price information and market assurance are recognized as the greatest obstacle to developing the potential of the mangosteen fruit. One effort to resolve that problems is by using the partnership. Mangosteen farmers in Karacak Village, Leuwiliang, Bogor, has already made a partnership with PT. Agung Mustika Selaras. The aim of this research is to describes the implementation of partnership mechanism between PT. Agung Mustika Selaras with mangosteen farmers in Karacak Village, Leuwiliang, Bogor and also to analyzes the influence of partnership toward mangosteen farmer’s income in the Karacak village, Leuwiliang, Bogor. Data for this research was taken from October 2012 to November 2012. The respondent of this research is all partners farmer in Karacak village with the amount 23 farmers and non partner farmers with the amount 25 farmers This research is analyzed by using descriptive analysis, descriptive statistical , analysis of farming income, and the ratios (R/C).

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.
