Judul: Analisis kelyakan usaha sistem pertanian terpadu di AD Farm di Kecamatan Leuwisadeng Kabupaten Bogor
Abstrak: Sistem pertanian terpadu merupakan konsep pertanian yang menerapkan pengolahan limbah sehingga dapat digunakan kembali. Konsep pertanian terpadu dapat mengoptimalkan seluruh sumberdaya yang ada, sehingga limbah yang dihasilkan dapat memberi tambahan manfaat bagi usaha yang dijalankan. Salah satu usaha yang menerapkan konsep pertanian terpadu adalah AD Farm. Komoditi utama yang dihasilkan oleh AD Farm adalah Cabai, Jagung, Pepaya Calina, Jambu Kristal, Ayam Broiler dan Domba. Selain komoditi utama juga terdapat komoditi sampingan yang dihasilkan oleh AD Farm yaitu Babycorn, Pupuk kandang dan Kompos. Tujuan dari penelitian ini yaitu menganalisis struktur biaya usahatani, nilai penerimaan, pendapatan, rasio R/C dan usahatani dengan menerapkan sistem pertanian terpadu. Metode analisis yang digunakan adalah analisis pendapatan usahatani dan R/C Rasio. Hasil penelitian menunjukkan dengan mengadopsi sistem pertanian terpadu AD Farm dapat mengurangi biaya untuk pembelian pupuk. Selain itu dengan menerapkan sistem pertanian terpadu AD Farm dapat mengurangi jumlah buah yang rusak karena lalat buah pada komoditi Jambu Kristal dan Pepaya Calina dan menyebabkan penerimaan meningkat. Sehingga dapat dinyatakan dengan menerapkan sistem pertanian terpadu AD Farm dapat memperoleh peningkatan keuntungan.

Judul: Analisis usahatani terpadu pada Anugrah Farm di Kecamatan Tajur Halang Kabupaten Bogor
Abstrak: Integrated farming system is a business system that combines the components of agriculture, such as plants, animals and fish in a union. Longyam is one of the integrated farming system concept that combine the maintenance between fish and poultry. The purpose of this research was; 1) to analyze the effect of integrated farming system to the cost structure, revenue, additional benefits, income, and contribution of Anugrah Farm businesses, also 2) to analyze the efficiency level of Anugrah Farm‟s businesses. This research used farm income analysis method that include cost, revenue, and the business efficiency level analysis. Research shows that cost and revenue from chicken poultry method is higher than other businesses. An additional benefit of integrated farming was received cost saving and chicken feses transfer price. In business contribution, chicken poultry business is more contribute than catfish business to longyam‟s revenue. Chicken poultry business is more efficient to develop, with the value of R/C ratio is higher than other businesses.

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.
