Judul: Analisis Perencanaan Laba Jangka Pendek dan Prospek Usaha Ayam RAs Pedaging (Studi Kasus di Peternakan "X", Kabupaten Pandeglang)
Abstrak: Tujuan dari penelitian ini adalah (1) menganalisis struktur biaya dan penerimaan Peternakan “X”, (2) menganalisis perencanaan laba jangka pendek Peternakan “X” dan (3) menganalisis prospek usaha peternakan “X” dimasa mendatang. Penelitian berlangsung mulai bulan Maret – April 2006 di Peternakan ”X”, Desa Citalahab Pandeglang. Penelitian ini didesain sebagai studi kasus yang bersifat deskriptif analitis. Data yang diperoleh dianalisis dengan analisis peramalan komponen anggaran, analisis perencanaan laba jangka pendek dan analisis sensitifitas. Hasil penelitian menunjukan metode terbaik untuk peramalan produksi, harga pakan dan harga jual ayam broiler yaitu metode rata-rata bergerak linear, sedangkan harga DOC dengan menggunakan metode pemulusan eksponensial tunggal pada α = 0,7, kemudian dilanjutkan dengan metode smoothing (pemulusan) eksponensial linear dari Brown. Pemilihan metode tersebut didasarkan pada pola data dari periode sebelumnya, nilai MSE (Mean Square Error) dan nilai MAE (Mean Absolut Error) yang terkecil.

Judul: Analisis perencanaan laba jangka pendek dan prospek usaha ayam ras pedaging studi kasus di Peternakan "X", Kabupaten Pandeglang
Abstrak: The entrepreneur of broiler business has to realize the opportunity and threat of the future. Known the fix cost and variable cost which will give the impact to output volume is necessary. These information are for business analysis and future profit orientation. The aims of this research are: (1) To analyze cost structure and revenue of Peternakan “X”, (2) To analyze short term profit planning of Peternakan “X”, (3) To analyze business prospect of Peternakan “X” in the future. This research was carried out at Citalahab Pandeglang District during March until April 2006. Data analysis are consist of budget forcasting analysis, short term profit planning analysis and sensitivity analysis. Peternakan “X” has variable cost structure which higher than fix cost. It is caused by the use of feed cost reaches 73,089% from total variable cost. The revenue of Peternakan “X” is comes from broiler, chaff and bag sock sales also mortality and FCR incentives. The result of short term profit planning shows: (1) The lowest break even point value is occurred on period 15, that is Rp 56.085.895,90 (2) The highest margin of safety is occurred on period 15, that is 88,27% (3) The highest shut down point is occurred on period 18, that is Rp 28.551.388,80 (4) Degree of operating leverage is 1,1 times, (5) The highest contribution margin is occurred on period 15, that is Rp 63.028.437,00. That value is very small if it is compared to the amount of revenue which has happened in Peternakan “X”. This situation shows good business opportunity to the future.

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.
