Judul: Cash liquidity in the adoption of new cropping systems in central Lampung Indonesia
Abstrak: Linear programming approach was utilized to determine the feasibility of new cropping systems which give the highest income to farmers subject to capital, labour and land constraints. The results of the optimal solutions in this study have shown that at the present levels of beginning capital, labor and land, improved experimental cropping patterns introduced by Central Research Institute for Agriculture (CRIA) dominate the patterns to be adopted. The results show that an increase in beginning capital causes a decrease in cultivated area of old or farmers' patterns. Increasing the level of interest rate affects the patterns to be adopted by shifting cultivated area of the improved experimental patterns to the farmers' patterns. The improved experimental patterns have not been adopted in the presence of beginning capital shortage as well as credit shortage. Under the present conditions of available resources without capital generation in the model, credit is an important constraint in the production process and that added credit adds to net income. The hypotheses that the present level of credit used is not at optimum level is thus accepted. Parameterizing of available credit indicates further acceptance of the hypotheses that increasing cash flow through short-term credit will increase farm income and land use. This study also suggests that the credit received must be allocated within two seasons in order to maximize farm income. This allocation is important if capital generation is not involved in the farm business. In other words, credit for the second season is a necessary factor in maximizing farm income or in adopting improved experimental patterns. The farmers have more income and wider area to be cultivated Loan if the maturity is extended to 12 months rather than 6 months, present loan maturity. The findings allow us to hypothesize that extending loan maturity will increase farm income due to a shortage of capital in the second season. However, the above findings come out with the assumption that no risk aversion involved in the farmers' decision in adoption new improved experimental cropping patterns. Those findings as an optimal solution of linear programming approach are based on the assumption that constant return to scale is a characteristic of function. its production The linearity assumption in the objective function also makes the model inapplicable for activities that are inversely related e.g. the increase in output results in the lowering of the market price, farm size and others. Therefore, in order to achieve the objective

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: 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.
