Judul: Pola Kemitraan antara Petani dengan UBH-KPWN dalam Usaha Hutan Rakyat Jati Unggul Nusantara di Desa Ciaruteun Ilir, Kabupaten Bogor
Abstrak: Usaha Bagi Hasil Koperasi Perumahan Wanabakti Nusantara (UBH-KPWN) is a business unit developed by the Forestry Department engaged in the farming of National Superior Teak (JUN). UBH-KPWN applies the concept of profit sharing partnership in farming activities. This partnership system is specifically made by UBH-KPWN in order to maintain the farming continuity of national superior teak (JUN). The partners of UBH-KPWN include farmers, investors, landowners and the village government. To determine the forms of partnership between UBH-KPWN and its partners (farmers, investors, landowners and the village government), it is necessary to study the feasibility and the extent of partnership, whether it is beneficial to both parties. This research was conducted from April through June 2011 in the village of Ciaruteun Ilir, Cibungbulang District, Bogor Regency. The data in this study were collected using interviews and a survey. The respondents were selected by a stratified purposive sampling method based on the land area under cultivation. The number of respondents was 60 people. The analysis of the feasibility of community forests in terms of partnership was done in two phases: (1) analysis of cost sharing and (2) partnership-level analysis by a scoring method. The partnership pattern of the community forest in Ciaruteun Ilir village is feasible for the farmers, UBH-KPWN, investors, landowners and the village

Abstrak: The aim of study is to explain participation of farmers for managing forest, to explain the pattern of relation between farmers and cooperative on forest management which is compared to the pattern of relation between farmers and middlemen, and to explain perception of farmers about the role of forest management on increase total income of farmers. The study used survey method with random sampling for respondents. Total of respondents were 33 respondents; 18 JUN farmers, 12 non-JUN farmers, and 3 respondents of cooperative. Participation of farmers to follow steps of forest management is a factor for affecting the total good trees of farmers. The pattern of relation between farmers and cooperative is single stranded. This relation is defined as single commercial relation and it is also happened between farmers and middlemen. The same relation pattern to cause the positive and negative impact differently for farmers. Perception of farmers included in the category is high (>50%). Forest mangement is able to increase the total income of farmers from wood sale with cooperative and middlemen are as wood buyers.

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.
