Judul: Sistem Pemasaran Rumput di Kepulauan Tanakeke, Kabupaten Takalar, Provinsi Sulawesi Selatan: Struktur Perilaku, dan Keragaan Pasar
Abstrak: South Sulawesi is one of the central of seaweed production in Indonesia. This study focuses in Tanakeke Islands, Takalar Regency that produced most of the seaweed in South Sulawesi. The objectives of this study were (i) to identify market structure of seaweed in Tanakeke Islands, (ii) to describe market conduct of seaweed in Tanakeke Islands, (iii) to determine market performance of seaweed in Tanakeke Islands. According to S-C-P approach (Structure Conduct Performance). The research indicated that market structure of seaweed was oligopsonistic, and the majority single marketing institution is determining the seaweed price. It also showed there were four marketing channel, (1) farmersmiddlemen in village-middlemen in subdistricts-wholesaler-exportir level, (2) farmers-middlemen in village-wholesaler-exportir level, (3) farmers-middlemen in village-wholesaler-exportir level, (4) farmers-middlemen in village-exportir level, where the first marketing channel had the highest total of the marketing margin. This implies the farmer share has the lower value. The research revealed weak market integration between farmer and middlemen. Conversely, market integration at farmer level and middlemen was highly, especially in the long run.

Judul: Analisis value chain system dan strategi pemasaran rumput laut di Kabupaten Maluku Tenggara, Provinsi Maluku
Abstrak: Analysis of value chain system is a strategic analysis tool that is used to better understand the competitive advantage found in the activities of upstream to the downstream, from the nursery to the seaweed marketing process in Southeast Maluku district. The purpose of this researchs to study the system of seaweed products value chain in Southeast Maluku regency at present and analyze and determine the marketing strategy of seaweed products in Southeast Maluku regency to create efficient marketing processes. Primary data were obtained from direct observations and interviews with the operational activities of each value chain actors. Sampling was purposive sampling method, the number of respondents is 41 people. Data processing used to analysis of value chain system for the process from upstream to downstream, value added analysis to look at the technical factors that influence the production capacity, the amount of raw materials used and labor, while the factors that influence the market price of output, wage labor, and the input values are adjusted for margin trading system as well as a SWOT analysis to formulate marketing strategies seaweed production. Alternative marketing strategies are analyzed by using SWOT method with respect to any description of the expected value chain mapping that can improve the trading system that is more structured and commodity processing in each of the pilot areas is to maximize the impact of commodity. These results indicate that the main activity of which is the process of breeding, outbound logistics, marketing and sales as well as the stage, which is also supported by the infrastructure, human resources management, as well as technology development of seaweed. The analysis of value added of seaweed on fishermen Rp. 287.67, small traders Rp. 550 and large traders Rp. 850 SWOT analysis of the results obtained from the internal analysis of 2.474 weighted score and external analysis of the results of 2.634. The combination of internal and external factors shows the position of the object being studied is located in the space V of stability (keep and maintain) that offered a viable strategy for the stable position of the fishermen are able to do the activities and measures market penetration improving product development strategy to sustain and maintain the performance that has been achieved.

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.
