Judul: The Effect of village labor resources on the feasibility on new cropping system in Indonesia
Abstrak: Transmigration in Indonesia refers to the movement of people from densely populated regions to less populated one for the purpose of improving their economic situation. This is one of the alternatives for alleviating Java's population pressure problem and increasing development in rural areas. The introduction of multiple cropping in resettlement areas is seem as a key to increasing the welfare of transmigrants. The main objective of this study is to determine the feasibility of experimental multiple-cropping patterns with respect to labor supply in selected upland and lowland rice growing villages in transmigration projects of Lampung Sumatra. In addition to this, another objective is to examine the role of family labor, hired labor and exchange labor in increasing cropping intensity for achieving the socio-economic objectives of farmers...

Judul: Optimal allocation of resources in the coastal wetlands of Sumatra and case studies to tests the results
Abstrak: There are three major groups of people that live in Muara Telang study area, these are local residents, Buginese, and transmigrants. They grow rice, coconuts, bananas and other crops. Coconuts and bananas are the cash crops of the area. The objective of this study is to determine the economic efficiency of the cropping system as it was applied by each of those three major groups of people in Muara Telang. Also it compares the costs, yields, labor use, net returns over time for the cropping systems applied by each. This study has also examined the nonformal institution of the Buginese farmers and the methods of clearing coastal wetlands by the three groups of people in Muara Tcl . The data collection was carried out by interviewing the farmers in their houses. Analysis of the data was done by using a linear programming model, which was developed for each of the three major groups of farmers in Muara Telang. The result shows that the farmers in Muara Telang have not yet allocated their existing scarce resources to alternative activities efficiently, and there is something to be gained from reallocation of these resources. The important limiting factors of production are planting, weeding and harvesting labor for large sized farms (local resident farms), harvesting labor for middle sized farms (Buginese farms), and weeding labor for smaller farms (transmigrant farms). Using hired or exchange labor is one way for solving these limiting factors which if applied, could lead to an increase of more than 40 percent in the farmers' income. Price policy was found not to be a practical policy instrument in changing the product mix or increasing the farmers' income. This is shown by the fact that product prices would have to change very drastically if any significant changes in production patterns are expected. Moreover, the distributional effect of increasing prices would only benefit the larger farmers, who already have higher incomes.

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.
