Judul: Analisis Risiko Usaha Peternakan Ayam Broiler Dengan Pola Kemitraan Dan Mandiri Di Kota Sawahlunto/Kab. Sijunjung
Abstrak: One commodity that many farms are cultivated by breeders of broiler chickens. Broiler breeding process has a shorter culture period than other farm commodities. Broiler chicken farming is inseparable from the existence of business risks. The most common risk is the risk of production and price risk. On-farm production of plasma risk is one risk is quite high, while the independent farm price risk is the risk that a major effect on earnings. This study aims to analyze the sources of risk that affecting farmer’s income, the effect of production risk and price risk to the farmer’s, analyzing the influence of a partnership, as well analyzing alternative strategies appropriate to address existing risks. The method used is a risk analysis, revenue analysis and analysis of the revenue balance (R/C Ratio). The comparison of income between farmers and the plasma independent of Rp 58 618 500 and the value of R/C Ratio of the received independent farmers is 1.16. while in this period plasma farmers suffered losses of Rp -4 465 900 and R/C Ratio of 0.73

Judul: Analisis Risiko Produksi Pada Usaha Peternakan Ayam Broiler Bermitra dan Mandiri di Kabupaten Serang Propinsi Banten
Abstrak: One of the many farms which has the potential national meat contribution is broiler chickens farm. Serang Regency is one of the broiler production centers in Banten, and it encourages the emergence of partner companies. PT.Berkah Mitra Sejahtera is a company which forms a partnership with three broiler poultrymen in Serang District. There are few independent broiler chicken farms there. The aim of the study was to identify the sources of the farm production risks of the independent or contract farming, to analyze the likelihood of the risks and impacts of farm production risk sources,to compared risks production broiler chicken farm of independent or contract farming, to analyze and to analyze alternative strategies to handle the farm producton risk sources. There were four farm production risk resources found in the contract farming farms i.e, diseases whose average probability was 39.43 percent, weather changes - 31.93 percent, poorer DOC quality - 24.23 percent, and predators - 12.90 percent. Similiarly there were also four farm production risk resources found in the independent poultryman’s farm, i.e diseases whose probability of which was 50.00 percent, weather changes - 46.40 percent, predators - 23.30 percent, and poorer DOC quality - 18.10 percent.Based on t-test showed the risk production being largest for contract farming because p-value >α=0.05,so that no reject Ho. Risk mapping results indicate that there were two strategies, namely preventive and mitigation strategies. Diseases were a source of risk that had the highest possibility and the greatest 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.
