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.

Abstrak: Soy is the third most important food crop in Indonesia after rice and corn. Demand for soy in Indonesia has increased every year. Until now, Indonesia has been unable to meet the national demand for soy. This inability can be overcome by improving soy agribusiness system where marketing system is one aspect that needs to be fixed. Improvement of the marketing system aspect can be started from the central areas of soy production. West Java is the fifth province with the largest value of soy productivity in Indonesia. Cipeuyeum village, Cianjur regency is one of soy producing area in West Java. There are four channels of marketing system in this village with five institutions tha identified with the snowball method. This marketing system institutions perform each functions and face the diverse market structures. Quantitative analysis showed the most efficient channel with Rp917.00 for the marketing margin, 85.89% for the farmer’s share value, and 7.06 for ratio of profit to cost.

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.
