Abstrak: 'Go organic' program in 2010 had positive impact on the marketing activities of organic vegetables. A kind of organic agricultural products that increasing in demand is a source of vitamins, fiber, and also as long-term health investment. These awareness is also pushed by the education and income levels. As higher the public awareness of health gives motivation to farmers to provide this organic product that free from harmful chemicals. These products offered to the market with variety of different attributes with non-organic vegetables. Therefore it is necessary to study how the market segments and preferences are formed for the organic vegetable commodity. Through software of this study were analyzed using k-means cluster and conjoint analysis. The result shows a potential consumer is housewife with adult to old age that has levels of economic well-established. The most expected preference for consumers is the kind of d vegetables, it is leaves shape, the benefit is good for healthy life, and the attribute label for most consumer attention is the 'organic' word on the packaging.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
