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.

Judul: Modal Sosial Kelompok Tani Hutan Rakyat (Studi Kasus di Desa Damarwulan, Kecamatan Keling, Kabupaten Jepara)
Abstrak: Community-based forest management has been proved to be able to prevent forest degradation at some locations. So that, to sustain community forest it is important to consider social capital of community in forest management. The purpose of this study is to find out the farmer group activity and the management organization also to identify and assess individual characteristics and social capital of farmer group. This study was conducted at the Damarwulan Village, Keling District, Jepara Regency on April 2014 using survey methods from 30 farmers. Data collected using observation, interview, documentation, and technics analyzed descriptively. Based on the assessment, the individual characteristics of farmers was in the medium category, while the social capital was at the high level. Individual characteristics that significantly correlated to the elements of social capital based on Spearman correlation were non-formal education, formal education, land area, and period of residential. Individual characteristics that significantly correlated to the social capital level were formal and non-formal education, period of residential.

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.
