Judul: Analisis pengaruh kompensasi petani terhadap produktivitas usaha: studi kasus Kawasan Agropolitan Pacet, Kabupaten Cianjur
Abstrak: Kompensasi yang diberikan akan mempengaruhi produktivitas dan tidak hanya diberlakukan pada karyawan yang bekerja di perkantoran, tetapi hal tersebut berlaku juga pada tenaga kerja di semua lapangan pekerjaan. Salah satunya adalah penerapan sistem kompensasi yang diberlakukan kepada petani di Kawasan Agropolitan Pacet, Kabupaten Cianjur. Penurunan produktivitas Kawasan Agropolitan Pacet, bukan karena pengalihfungsian lahan semata tetapi juga dikarenakan sebagian petani yang menggarap lahan tersebut beralih profesi menjadi pedagang dengan anggapan pendapatan finansial yang diperoleh akan lebih menjanjikan

Judul: Analisis karakteristik usahatani komoditas hortikultura dan faktor-faktor yang mempengaruhinya di kawasan agropolitan pacet - Cianjur
Abstrak: Research result indicates size of the land ownership on research locations in agropolitan area (Sukatani and Sindangjaya villages) were relative narrow, with farm domination pattern for both villages were as land owner (1), as rent, sharing holder, mortage (2), as a governmental property (3). Meanwhile the farm enterprise characteristic the farmer was tends to conduct multiple cropping planting pattern (polyculture). Planting pattern was formed using four considerations, such as: (1) technique of cultivation, (2) market request, (3) the limited of capital and labour owned by farmer and (4) socio-economic condition. Crop rotation with high and quick intensity, causing type fertilizer and chemicals used immeasurable progressively. Based on farm enterprise characteristics on research location, if conducted of efficiency analysis of farm enterprise, indicate that all of R/C ratio value were above 1 that means all commodities were efficient. Meanwhile, analysis of multiple regression productivity farm enterprise productivity in agropolitan area indicate that variable having a significant effect on reality to farm enterprise advantage were land size, fertilizer, labour, and dummy variable about conservation activity (-p<0.05). There are three free significant variables in the factors of model binary logistic regression analysis that influence the farmer’s role in application of soil conservation techniques. Those are (1) land governance, (2) planting pattern, and (3) land ownership.

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.
