Judul: Risk Communication to Increase Independence of Swamp Rice Farmers in South Sumatera
Abstrak: The risk of farming rice swamps that have a lot of problems in managing farming rice makes farmers swamp affected by the level of production and income were received fairly low. Low self-reliance of farmers of rice marsh in the management of land marsh caused by information, innovation, and the ability of communication risks swamp rice farmers who are still classified as low. Management of risks rice swamps are highly influenced by the condition of nature and the environment topography of the area swamps and system of cultivation which used the farmers both the means of production are used, monitoring the organism nuisance plants as well as fluctuations in the price of grain and rice. Communication of risk is part of the communication that can provide input information that is kept constant and reciprocal forth between extension worker, groups of farmers, governments, and partners farmer so happened to increase the independence of farmers in farming rice swamp to involve farmers in the development of the means of agricultural, liveliness extension in the dissemination of innovation information swamp rice farming. In addition to the price that continues to dynamically follow the request tastes market. Increasing the ability of farmers to answer the challenges of law No. 19 of 2013 concerning the protection and empowerment of farmers. The ability of farmers to establish themselves as private are independent of the terms of the power of competitiveness, power filter, and power sanding, need to be aspects of the amplifier main to run the farming of rice that manage the farmers as a source of eye livelihood principal. The purpose of the research was (1) to analyze the communication of risk, the level of independence of farmers, and the factors that affect the farming of rice in the District Banyuasin and Regency of Ogan Ilir, South Sumatera. (2) analyze the factors which predominantly affect the communication of risk and the level of independence of farmers in farming rice swamp. (3) developing a risk communication strategy formulation in increasing the independence of swamp rice farmers in South Sumatra. The research was using the approach to the study of quantitative and using survey techniques. The study involved 294 samples from two districts. Withdrawal of samples carried out by random stratified to see the data that is held respectively in the district were selected in District Ogan Ilir and District Banyuasin. Withdrawal of samples to take from some groups that belong in the group of farmers and distributed questionnaires and on the interview following the guidelines for the interview. Risk farming rice swamps that occur have the intensity that enough was which often happens flood seasonally, as well as the attack of pests which reduce the production of farmers as well as fluctuations in the price of grain is often no uncertain which impact on the income of farmers. The ability of communication risk of farmers derived from the activities of farmers in the follow socialization in villages and groups of farmers and media information directly and not directly. The process of communication of risk occurs periodically continues to

Abstrak: Rice is one of the main food in Indonesia. Demand for rice increases as the population increases. The national rice production has not been able to meet the needs of national consumption. In the last number of years, Indonesia has to import rice to meet the demand. On the other hand, the risks and impacts of climate anomalies, such as floods and droughts, become more frequent and more intense. The climate hazards have been found to be main threat to agricultural production systems and national food security. In some specific area such as in coastal areas, the occurrence of environmental damage coupled with the problem of rising sea, flood has already become an annual disaster. The floods last for a few months during the rainy season and this does not allow farmer to plant the rice in this season. This research examines the potential of rice floating technology to address the problem of the annual floods which occurred in Pamotan Village, Ciamis District, West Java and Rawaapu Village, Cilacap District, Central Java. Floating rice technology addresses the flood risk using raft as cropping medium. The results of the analysis indicated that the floating rice technology is very potential to be applied in areas that have already been experiencing annual flooding problem. The economic feasibility of this technology is also very high. The total revenue earned by floating rice farming is greater than the total income of the conventional rice farming in Pamotan and Rawaapu. This is demonstrated by the higher ratio of revenue and cost (R/C) of floating rice farming than that of the conventional technique. The R/C of the floating rice reached 2,03 while that of the conventional rice was only 1,71. This suggests that the floating rice cultivation is not only very potential to address the problem of permanent flood but also for increasing farmers income.

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.
