Judul: Potensi Pengembangan Sapi Potong di Kabupaten Sijunjung Propinsi Sumatera Barat
Abstrak: Agricultural land in Sijunjung District that has not been optimally utilized could be used for the development of beef cattle farm. The development should conform land suitability as a reference to determine beef cattle development to achieve the government's target of meat self-sufficiency in 2010. This study aims to foresee the potential of land in Sijunjung District for development of beef cattle using a combined 2006 Landsat images, LREP maps and other supporting data through, financial analysis, and the desired rearing cattle the local community. The results indicate that the potential lands for the development were about 120,063 ha or 38.35% of the existing land area, which consists of mixed garden (100,359 ha), 3,247 ha of abandoned land, 11,027 ha of paddy fields and 5,428 ha of bush. Actualy, land carrying capacity is 55,518 Animal Unit, and the potential carrying capacity is 134,722 Animal Unit. The results of the NPV analysis for all farming schemes were positive, with B/C Ratio> 1, and the IRR> outweighed the applicable interest rate. Assessment using AHP showed that the caging system was preferable (0.650) than shepherd-based farming (0.350) with a value of inconsistency about 0.05.

Abstrak: The objective of the research were 1) to identification internal and ekstemal factors which can influences beef cattle farming development in Surade Sub-District, 2) to formulate the strategy of beef cattle development in Surade Sub-District. Primary data obtained by direct interview with the beef cattle farmer, used questionaue as the tool. Secondary data obtained from relevant institutions sources that related with the topic of the research, the data analyzed descriptive quantitative method. The result of feseability study analysis showed Net Present Value (NPV) equal to Rp. 5,670,144,68, Benefit Cost Ratio (BCR) equal to 1.52, Interest Rate Ratio (IRR) equal to 22% and Pay Back Period (PBP) equal to 4 year. The return cost ratio (RiC ratio) of beef cattle farm business analysis, showed that ratio as 1.70 value. It means that the beef cattle farm business were profitable with earning equal to Rp. 2,286,006,94. Base on data feseability study analyzed showed beef cattle development in Surade Sub-District were feseable. Result of analysis of SWOT in the form of strategy S-0 that is cooperation with financial institution to increase working capital, cooperation with government institution to introduce artificial insemination technology. Strategy of W-0 that is re-activated farmer group in marketing beef cattle product, more recruit farmer adviser to increase farmer knowledge in beef cattle farming. Strategy S-T that is to increase farmer knowledge in animal health, to increase animal productivity by applicated advance breeding technology. Strategy W-T that is to increase farmer personal skill in beef cattle farming, it can be implemented by coopemtion between farmer group and government intsitution.

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.
