Judul: Hubungan perilaku komunikasi dengan praktek budidaya pertanian organik
Abstrak: Sustainable agriculture development holds an important issue now days. Famers’ Communication behaviors in information seeking constitute a pivotal position in order to increase the farmers’ autonomy. The objectives of this research were: (1) to describe the practices of organic agriculture cultivation in red-onion farmers, (2) to analyze the correlation between farmers’ characteristics and the red-onion organic agriculture practices, (3) to analyze the correlation between farmers’ communication behavior and red-onion organic agriculture practices, (4) To analyze the correlation between farmers’ assessment towards agricultural technology, (5) to analyze the correlation between the red-onion organic agriculture practices and the degree of farmers’ autonomy in getting the production tools. This research was designed qualitatively using survey method. The data was analyzed using Tau-Kendall Test. This research produced several results such as: an Organic practice that has been conducted by the farmers was not utterly organic. The organic performer’s behavior was influenced by communication behavior variable and individual characteristics’. The farmers’ Autonomy was much correlated with farming activities’ behavior.

Judul: Faktor-Faktor yang Mempengaruhi Sikap Petani Padi Sawah terhadap Penerapan Pertanian Organik
Abstrak: Organic farming is one of the alternative solutions for environmental damage due to the use of synthetic materials input. Therefore, the objective of the study is to describe ricefield farmers attitude, to analyze attitudinal differences between non, semi, and organik ricefield farmers, to analyze the influencing factors on ricefield farmers attitude toward the implementation of organic farming. The study was conducted by survey methods on April 2013 in Magelang Subregency. 105 respondets was selected through sensus sampling and snowball sampling technique. The results shows that the ricefield farmers in Magelang Subregency are tends to have positive attitude towards the implementation of organic farming. Also, there is attitudinal differences among farmers. Non formal education, farming ecperience, capital ownership, acces to agricultural input material, and the values of the group has effect on the ricefield farmers attitude.

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.
