Judul: Dampak Kebijakan Pemerintah Terhadap Keuntungan dan Daya Saing Rumput Laut di Kepulauan Tanakeke Provinsi Sulawesi Selatan
Abstrak: Seaweed is one of the leading commodities in the Fisheries Revitalization Program in South Sulawesi. Production and export growth of seaweed over the last five years experienced a significant increase but will not be offset by the value of export receipts caused by the quality of seaweed produced in Tanakeke islands so low that the price of seaweed in the international market is low. Therefore, This study aims to analyze: (1) the level of financial and economic benefits, (2) the competitiveness of commodities seaweed the through competitive and comparative advantage, (3) the impact of government’s input-output policy on the competitiveness and benefits of commodities seaweed. Policy Analysis Matrix (PAM) was employed in this study in order to calculate the private and social prices of revenue and cost of the seaweed in which the social price was calculate from the shadow price of output is based on FOB prices in the port of export (Makassar) and private prices from seaweed adjusted real actual price received by farmers Tanakeke Islands. The results showed that: (1) the seaweed in Tanakeke islands was profitable (both privately and socially profitable), (2) it had competitive advantage (PCR < 1) and comparative advantage (DRC < 1), (3) the impact of government policy on output indicates negative result means that government intervention has not been effective so that the prices received by farmers is lower than international prices.

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.
