Abstrak: The objectives of this research were: (1) to analyze effect of characteristic factors such as social dynamic, physical environment, farmers’ characteristics and socio-economic environment of entrepreneurship communication patterns; (2) to ensure important factors that will strongly influence the increasing of entrepreneurship capacity; (3) to formulate effective communication pattern for entrepreneurship capacity development efforts of vegetable farmer in the Taiwan’s technical mission in two districts in Indonesia. This research resulted several outputs, namely: (1) communication pattern of farmers’ entrepreneurship in Taiwan’s technical mission was categorized good enough and significantly influenced by group dimensions i.e membership and group climate on social dynamics; (2) the development of farmers’ entrepreneurship capacity in Taiwan’s technical mission was categorized good and it was directly influenced by education level characteristics and farmers’ business experiences, it was also influenced by physical environment on dimensions of communication infrastructure and technology characteristics, it was significantly influenced by socio-economic environment on dimension of support social system and mass media information, and also significantly affected by family support dimension, institutional support and local knowledge functioning of socio-economic environment and significantly influenced by dialogic dimension on farmers’ communication entrepreneurship pattern; (3) effective communication patterns regarding development of entrepreneurship capacity of farmers was dialogic communication patterns, and communication pattern itself were strengthened by these factors: social dynamic on group climate and group dimension of membership dimensions. (4) some of the forms of technical skill, social skill, and managerial skill that potentially can improve and compete towards farmers were entrepreneur technical skill, social skill, and managerial skill. By improving their technical skill, social skill, and managerial skill, it was expected farmers were able to improve their productivity, income, autonomy which at the end can develop farmers’ welfare in Indonesia.

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.
