Judul: Analisis Pendapatan Dan Faktor-Faktor yang Mempengaruhi Produksi Usahatani Kedelai di Desa Cipeuyeum, Kecamatan Haurwangi, Kabupaten Cianjur
Abstrak: Soybean is a crop which is consumed by Indonesian people in the form of refined products. West Java province is one of the largest soybean producing areas in Indonesia. One of the areas in West Java, which produces soy is Cipeuyeum village. However, soy is still become the interlude for the farmers. The benefits received by farmers over soy farming activities will be measured through analysis of the farming income and the value of R-C ratio. In addition, the influence of factors of production to the production of results will be viewed by using the multiple regression analysis. Based on the analysis of income, farmers who harvest the soybeans upon young and old pods suffered losses during the growing season. Factors of production which is used by farmers are land, seed, urea, KCl, phonska, liqiud fertilizer, MOL, workers, dan insecticide. Factors of production which gives a positive influence of soy production results include urea, phonska, dan insecticide.

Judul: Pendapatan Usahatani Kedelai di Desa Sukasirna Kecamatan Sukaluyu Kabupaten Cianjur
Abstrak: Soybean is one of important food crops in Indonesia after rice and corn. Fulfillment of dried soybean in the country has not been able to meet the demand, so the old pods cultivation and productivity still need to be enhanced. The purpose of this research was to examine the variability, farm income analysis, as well as to analyze the ratio between revenue and cost (R/C) of the old and young pods soybean in Sukasirna Village, Sukaluyu District, Cianjur Regency. This research used descriptive and quantitative analysis, namely income analysis and R/C ratio. Income based on cash costs per hectare per season of old and young pods soybean is Rp 2 287 625.33 and Rp 680 142.42. Income based on total costs per hectare per season on old pods soybean is positive amounting Rp 578 796.95 and profitable to be developed. While in young pods soybean have negative farming income based on total costs per hectare per season which means young pods soybean farmers suffered a loss of Rp 129 199.46. Analysis of the ratio of R/C at the expense of cash in old pods soybean at 1.62 while on young pods soybean is 1.24. Value of the ratio R/C old and young pods soybean over the total costs of 1.11 and 0.97.

Judul: Sifat optik dan sifat listrik diode schottky film Barium Titanat (BaTiO3) berstruktur emas - BaTiO3 (Metal – ferroelektrik)
Abstrak: Diode Schottky (emas - BaTiO3) berhasil dibuat dengan ditumbuhkan di atas permukaan interdigital electrode berbahan emas(Au) menggunakan metode Chemical Solution Deposition (CSD) . Film BaTiO3 dibuat dengan proses annealing pada suhu 400oC dengan variasi holding time annealing 4 jam dan 10 jam. Karakterisasi sifat optik diode Schottky dilakukan menggunakan UV-Vis Spektrofotometer untuk memperoleh nilai energi gap Film BaTiO3. Nilai energi gap BaTiO3 pada dua perlakuan holding time annealing 4 jam dan 10 jam sebesar 3.27 eV dan 3.21 eV dan nilai energi gap tersebut termasuk dalam kategori semikonduktor. Karakterisasi sifat listrik diode Schottky dilakukan menggunakan LCR Meter yang didapatkan nilai konduktivitas listrik pada Holding time annealing 10 jam lebih besar daripada 4 jam. Kemudian, didapatkan nilai impedansi yang menunjukkan bahwa pada holding time annealing 4 jam lebih besar daripada holding time 10 jam. Didapatkan pula nilai konstanta dielektrik yang menunjukkan pada waktu holding time annealing 4 jam lebih besar daripada 10 jam.
