Judul: Kelembagaan penyuluhan partisipatif dalam pengelolaan hutan rakyat: studi kasus komunitas petani sertifikasi percabaan Dusun Pagersengon Kelurahan Selopuro Kecamatan Batuwarno Kabupaten Wonogiri Provinsi Jawa Tengah
Abstrak: The success of private forest can’t be separated from the contribution of various parties. The research objectives were to analyze the institution of private forest, to analyze stakeholder’s involvement, to analyze the processes and outcomes of participatory extension, and to formulate institution development strategy of participatory extension. The method used is a case study by which data collection was conducted by interview, observation, FGD, and documentation study. Poverty caused by land aridity awakened local leaders to realize the need for change. Observation of teak and mahagony plants that were able to survive in Selopuro made them to invite the neighbors to planting timber in their land. The invitation was rejected by the people so the leaders built a demplot with timber plants to show the public that timber plants were suited to the condition of Selopuro. Finally, people realized that their leaders were correct and people began to plant timber plants. Government, NGOs, foundations, and donor agencies also facilitated the community to achieve the expected change. The role of the parties run was different but with the same goal of helping people to help themselves. One of the impacts of participatory forestry extension is the improvement of community welfare.

Judul: Modal Sosial dalam Pengelolaan Hutan Rakyat Lestari di Kabupaten Wonogiri Provinsi Jawa Tengah
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.
