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.

Abstrak: Currently various community-based forest resources are found to have been able to save forests from extinction. It's rationale necessitates the need to incorporate social capital in community forest management and timber trade. The research objectives were (1) to identify and assess individual characteristics, elements of social capital and community timber trade patterns, (2) to determine and analyze the relationship between individual characteristics and the elements of social capital as well as community timber trade patterns, (3) to obtain the most appropriate strategy in the management of community forests and timber trade. Data were analyzed descriptively, using Spearman rank correlation, SWOT and QSPM analyses. The individual characteristics of farmers, based on the assessments, were in the medium category. The social capital was at the high level, at which people are generally committed to joint efforts, effective collaboration, collective and institutionalized action, expressing ideas to increase productivity, maximize mutual benefit and positive interdependence. The elements of community timber trade observed were the pattern of sale time, marketing chain and the sale system in three channels. The individual characteristics that were significantly correlated with the elements of social capital were age, formal education, non-formal education, income, and social status. The individual characteristics correlated with the pattern of the timber trade were the levels of formal and non-formal education, income and social status. The social capital that was correlated with the trade pattern in the certified sites was proactive measure, while in the uncertified location, apart from the proactive measures, the network had a positive correlation with the pattern of community timber trade. The selected strategy to strengthen management of community forests and timber trade was by improving people's knowledge of forest management and timber trade, which includes good cultivation people and timber trade patterns by conducting extension, training and development.

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.
