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.

Abstrak: Soy is a source of vegetable protein which has relatively lower price compared to other source from animal protein. The marketing of young soybean pods make the availability of old soybean pods decrease in the market. The objective of this research is to analyze functions of marketing, the agency, marketing channel, market structure and market behavior; to analyze marketing margin, farmer’s share, and the ratio of benefits to costs; to calculate value added of tofu, tempe, and tauco. Analysis method for value added was conducted with Hayami method. Collecting data was conducted with purposive sampling method. This study shown that there are three marketing channels for old soybean pods and four marketing channels for young soybean pods. The marketing system institutions perform functions of marketing and face the different market structures. The result showed that the third channel was relatively efficient to distribute old soybean pods. The channel which is relatively efficient in the marketing of young soybean pods was channel two. The results of value added showed that tauco has the largest value added ratio than tofu and tempe.

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.
