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: 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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
