Judul: Financial Feasibility Study of Straw Mushroom Farming in Bojongmangu Village Subdistrict Bojongmangu of Bekasi
Abstrak: Jamur merang adalah salah satu jamur konsumsi yang memiliki permintaan tinggi, sehingga banyak dikembangkan salah satunya di Desa Bojongmagu. Produksi jamur merang di Desa Bojongmangu memiliki kelemahan, yaitu produksi yang tidak menentu sehingga relatif rentan terhadap faktor lingkungan. Hal ini akan memengaruhi keputusan petani untuk berusahatani, karena tidak diketahui secara pasti kelayakan usahatani. Investasi yang diperlukan juga tidak sedikit dan produksi yang tidak menentu akan memengaruhi kelayakan usahatani. Tujuan dari penelitian ini untuk (1) mengidentifikasi aspek-aspek kelayakan usahatani jamur merang, (2) mengestimasi kelayakan finansial usahatani jamur merang, (3) menganalisis pengaruh penurunan produksi jamur merang, penurunan harga jual jamur merang, dan peningkatan harga kapas terhadap kelayakan usahatani jamur merang. Metode analisis yang digunakan yaitu analisis kelayakan finansial, analisis sensitivitas, dan analisis switching value. Usahatani jamur merang layak untuk diusahakan, karena telah sesuai dengan aspek-aspek kelayakan serta kriteria investasi yaitu NPV, Net B/C, Gross B/C, IRR, dan Payback Period. Penurunan produksi dan harga jual jamur merang segar memberikan dampak paling besar terhadap usahatani jamur merang., Straw mushroom is one of edible mushrooms has a high demand, it is widely developed, one of them in Bojongmagu Village. Productions of straw mushroom in Bojongmangu Village has a weakness, that is erratic production it is relatively vulnerable to environmental factors. This will affect the decision of farmers to farm, because it is not known with certainty the feasibility of straw mushroom farming. The investment required is also not small and uncertain production will affect the feasibility of farming. The purpose of this research for (1) identify feasibility aspects of straw mushroom farming, (2) estimate the financial feasibility study of straw mushroom farming, (3) analyzed the effect of decreasing production of straw mushroom, decreasing selling price of straw mushroom, and increasing the price of cotton on the feasibility study straw mushroom farming. The analytical method is financial feasibility analysis, sensitivity analysis, and switching value. Straw mushroom farming is feasible, because complied with the aspects and investment criteria, that is NPV, Net B/C, Gross B/C, IRR, and Payback Period. The decrease in production and selling price of straw mushroom had the biggest impact.

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.
