Judul: Analisis Kelayakan Usaha Kemitraan dan Kontribusi Pengelolaan Hutan Rakyat terhadap Pendapatan Rumah Tangga Petani (Studi Kasus Kelompok Tani Rimba Lestari di Desa Karacak, Kecamatan Leuwiliang)
Abstrak: Pengelolaan hutan rakyat pola kemitraan merupakan salah satu cara untuk mengatasi permasalahan modal dalam pembangunan usaha hutan rakyat. Kelompok tani Rimba Lestari, Desa Karacak dalam pengelolaan hutan rakyat mengembangkan pola kemitraan antara petani, pemilik lahan, dan pemodal atau investor. Pola kemitraan ini diharapkan dapat memenuhi kebutuhan bahan baku industri kayu dan dapat meningkatkan pendapatan petani. Tujuan dari penelitian ini adalah untuk menganalisis kelayakan dan keuntungan usaha yang diperoleh, hubungan dengan industri kayu serta kontribusinya terhadap pendapatan rumah tangga petani dalam pengelolaan hutan rakyat kemitraan. Kelayakan usaha hutan rakyat kemitraan secara finansial layak untuk dikembangkan dengan nilai NPV Rp438 894 413/ha/tahun, BCR 4.37, dan IRR 48%. Pembagian keuntungan kelompok tani Rimba Lestari dialokasikan untuk petani 20%, pemilik lahan 40%, dan investor 40%. Kontribusi hutan rakyat terhadap pendapatan total petani adalah sebesar 34.52 %. Kelompok tani Rimba Lestari melakukan pemasaran hasil kayunya berdasarkan pemesanan dari konsumen.

Judul: Analisis Pola dan Hubungan Kemitraan di Hutan Rakyat Rimba Lestari Desa Karacak Kecamatan Leuwiliang
Abstrak: Capital is factor which being a constraint in any development of community forests. Partnership is believed to be a solution of this problem. Farmer group of Rimba Lestari (RL) in Karacak village develop community forest based on bussiness partnerships between smallholder farmers, land owners, and investors. The purpose of this study was to analyze the pattern and level of partnership, as well as knowing the pattern of results based on an analysis of the financial benefits. Partnership of RL community forest management was belong to Agribussiness Operational Partnership pattern. Partnership of RL community forest management is worth to be developed, it shows from the view of partnerships rate of 721.67, that is categorized as Partnership Prima Madya. The relationship of the bussiness need to be encouraged and also it needs an agreements of corporation for make a sustainable management. In addition, the level of relationship and the partnership of RL community forest management is also feasible to be developed based on the analysis of financial benefit with a value of NPV Rp339 769 771 /ha/yr and BCR 4.63 /ha/yr.

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.
