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: Hubungan Keterdedahan Media Komunikasi dengan Perilaku Komunikasi Anggota Gabungan Kelompok Tani
Abstrak: Media communication has an important role in distributing information about agriculture, especially in rural areas. Communication media can influence the communication behavior of farmers. The issues raised in this research are: 1) How do the characteristics of individual farmers, farmers exposure the communication media and communication behavior of farmers in gapoktan Jaya Mandiri?, 2) the extent of individual characteristics affecting the relationship exposure farmers on communication media?, 3) the extent of the relationship farmers communication media exposure influence the communication behavior of farmers?. The research was conducted using survey research methods. The results obtained are characteristic gapoktan member farmers such as gender, age, duration of farming, land, education and access to communication media influence farmers expoure to communication media. Meanwhile, the internet exposure related to interpersonal communication behavior of farmers and radio exposure, meeting gapoktan exposure.

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.
