Judul: Modal Sosial dalam Pengelolaan Kebun Hutan (Dukuh) di Kecamatan Karang Intan Kabupaten Banjar Provinsi Kalimantan Selatan
Abstrak: Some researches on the management of community forestry have been done across continents with various themes. This study aims to measure the level of social capital in the management of forest gardens (dukuh), and analyze their effects on the dukuh performance. The research was conducted by using survey method. Two villages were purposively selected. Respondents were randomly selected from each villages with total number of 60 respondents. The results showed that the level of social capital in two communities in the management of dukuh is high, based on strongly held norms, values, beliefs, and rules. High social capital has facilitated the formation of the good dukuh performance, characterized by good levels of plant density, the value of high productivity, efficient use of resources, utilization of resources is fair, as well as the on going sustainable management of dukuh. This study concludes that social capital of Karang Intan community is still strong. Considering the high social capital in the community, the authors suggest the need for government support, especially through the enhancement of the role, the expansion of social networks, and strengthening the norms in force.

Abstrak: Some researchs on the private forest have been done across continents with various themes. This study aimed to measure the level of social capital in the management of private forest, and analyze their effects on the private forest performance. The research was conducted by using survey method. Two villages in two district were purposively selected. Respondents were randomly selected from each villages with total number of 60 respondents. The results showed that the level of social capital in two communities in the management of private forest is high, based on strongly rules and solidarity. High social capital has facilitated the awakening of the good private forest performance, characterized by good levels of high private forest productivity, as well as the on going sustainable management of private forest, benefits in the rules of fair management and efficient cost of private forest management. Strong social capital encouraged better performance. This study concludes that social capital of Wonogiri community is still strong. Considering the high social capital in the community, the authors suggest a need to increase the parties, especially the government to support forest management through the enhancement of the role, facilitating the expansion of social networks, and strengthening to aplicate the rules to the public.

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.
