Efficiency Analysis Of Soybean Marketing In South Sulawesi
The decrease on soybean’s real price and its competition with other crops in the usage of field is presumed as one of the causes of soybean’s harvest areal reduction. At the same time, there is a higher increasing on the demand of soybean compared to the production capability inside the country so that the deficit increases from 968,000 ton (1998) become 1.42 million ton (2006) and 1.45 million ton in 2008 or increases up to 8.74%/year. A research on the efficiency of soy marketing in South Sulawesi is done in three areas; Bone, Soppeng and Wajo. Site selection is done on purpose (purposive sampling) with consideration of the central areas of soybean production. The purpose of the study is to analyze the efficiency of marketing soybeans and the factors that influence soybean marketing margins in South Sulawesi. The study was conducted in April-June 2010. The results showed that the variables that determine the kedalai marketing margin is the price at the farm level, the number of stages through which is in phase III (marketing channels 2 and 4) followed by soybean varieties, while the average volume of soybean marketing, distance from home to market, the number of stages through which the first phase (line 6), II (channels 5 and 7), and IV (channels 1 and 3), as well as location marketing for the region and Wajo Soppeng no significant effect on the real level of 90 percent of the marketing margin . Subsequently obtained also that the longer the channel or the more marketing agencies who are involved in marketing of soybeans, will lead to greater the marketing margin.SimakBaca secara fonetik

Unmanned aircraft technology for agricultural land mapping and monitoring
Remote sensing data has been widely used for identification and monitoring agricultural land condition. The use of satellite imagery is constrained by cloud cover, reliance on vendor data provider, and inflexible acquisition time and location of data acquired. The Unmanned Aircraft Vehicle (UAV) technology has been developed and widely used for remote sensing applications for agriculture. Aircraft sensors that is almost similar with sensors on satellite imagery allows results which can be used to analyze condition of existing agicultural landuse and land cover as well as land resources by using bands VNIR, SWIR, thermal, radar or SAR. Application of UAV in Indonesia is plagued by high initial costs, limitations of available technology and human resource capabilities. Regardless of proficiency level constraints, UAV technology has good prospects and challenges operational used of agricultural sector. Research and development of UAV applications for agriculture needs to be done.

Gap analysis of Supply and Demand of Corn Forage Production Approach Sync Center, Feed Plant, Animal and Population in Indonesia
The demand for feed maize continues to increase each year in line with the development of livestock industry. Feed mills often complain of difficulties in getting maize, but farmers also often complain of difficulties to sell their maize. This prompted the authors to assess the gap of supply and demand for feed maize by synchronization approach to production centers, feed mills, and livestock population. The results showed that: (1) out of 10 provinces of maize production centers, 7 of which are the centers of feed mills (2) the demand for maize for manufactured feed in 2010 is 36.28% above the demand base on livestock population, and (3) in 2020, the demand for maize for manufactured feed is projected to be 28.52% above that of using population approach. If the production of manufactured feed is adjusted to meet only the existing livestock, the need for feed maize is much smaller. There is an indication that the orientation of the feed mills is not only to meet domestic demand, but also for export. With the limited resources, especially domestic maize production, the manufactured feed should be focused to meet the domestic demand for feed, so that would not interfere the development of domestic livestock industry.
Key Words: Supply, Demand, Feed Maize, Feed Mills, Livestock Population.

Perception and the adoption of the application of rice farmers, System of Rice Intensification (SRI) in the district Seluma
The adoption of agricultural technologies by farmers is largely determined by the needs and capabilities of farmers to implement these technologies in the field. System of Rice Intensification (SRI) is an approach in rice culture techniques that can improve efficiency and productivity of irrigated lowland rice. To know farmers perception and adoption of SRI in Seluma Regency, Bengkulu Province, has conducted research in the Bukit Peninjauan I, Sukaraja Subregency. This village is the only village in the Seluma regency who began developing the SRI technology since 2009. The experiment was conducted in March to April 2011 with a census of 65 farmer members Bumi Sari Farmer Group, implementing SRI program that organized by Agriculture Office of Seluma Regency. Descriptive data processed to determine the perceptions and level of adoption of SRI. While the factors that influence farmers’ adoption was analyzed by logistic regression. The results showed that all the farmers have a good perception of SRI, but the technology adoption of farmers is still low because 69.23% of SRI technology components have not been adopted by farmers as recommended. Of the six components of the SRI technology i.e. (1) age of young seedlings, (2) one seed per hole, (3) spacing, (4) irrigation, (5) mechanical tillage, and (6) intake of organic matter, only the spacing and irrigation is adopted. The low adoption of SRI caused by the high risk to be faced such as seeds moved into the field is still too young (age 8-15 days after seedling), and pest and disease threats to the plant that only one seed per planting hole. Additionally mechanical tillage and intake of organic material was not adopted because of the perceived increase farmers’ labor and the cost of rice production. SRI farmers’ adoption of technology is not affected significantly by age, educational level, the area of land tenure and income level.

Multitype branching processes theory was used to approximate the survival of mutant genes in a two-locus diploid population reproduced by partial selfing. It is concluded that in the two-locus situation, where there are initially two mutant genes which have epistatic effect on fitness, tight linkages between the two loci is necessary for the survival of the mutant genes. If recombination is possible, a population with a high rate of selfing is more likely to accumulate epistatically favourable genes than one reproducing largely by random mating. This advantage of selfing becomes more pronounced as the strength of selection toward the favourable genes increases.
Key words: Survival Probabilities; partial selfing; selection.
