Judul: Daya Saing Ekspor Komoditi Hortikultura Indonesia di Pasar ASEAN
Abstrak: Horticulture is one of agricultural sub sector of Indonesia which has quite good potential in international market, such as ASEAN. The objectives of this research are to analyze condition and the competitiveness position of Indonesian horticultural commodities in ASEAN’s market, also to formulate strategy which leads to increase the export competitiveness of Indonesian horticulture. The export competitiveness of Indonesian horticulture is analyzed using Revealed Comparative Advantages, Export Competitiveness Index, and Acceleration Ratio methods. The examined commodities in this research are cut flowers, mangoes, mangosteens, guavas, avocadoes, watermelons, potatoes, tomatoes, gingers, and curcumas. Considering the classification based on the analysis, we can coclude that commodities which have export competitiveness are mangoes, mangosteens, guavas, avocadoes, watermelons, potatoes, gingers, curcumas, and cut flowers, whereas tomatoes have less export competitiveness in ASEAN’s market

Judul: Dayasaing dan Permintaan Ekspor Sayuran Indonesia di Negara Tujuan Utama
Abstrak: The export commodities competitiveness is one of many indicators used for measuring the economic growth of a country. This research analyzed the export competitiveness of the five Indonesian vegetables, including potatoes, tomatoes, onions, cabbage, and chili which are delivered to five major destination countries and compared with competitor countries by looking at the comparative and competitive advantages as well as the factors that influence it. The period of analysis from 2008 to 2012 using Releaved Comparative Advantage (RCA), Export Product Dynamic (EPD), and the Gravity Model which used the data panel regression approach E-views 6. The result of this study indicates that the Indonesian commodities of vegetables do not have a comparative advantage better than its competitors, namely Netherland and China to the world. On the other hand, Indonesia has the best competitive advantage compared to its competitors. The factors that affect is Economic Distance, GDP, Exchange Rate, Population, and the Price of the Export with different results on each of the commodities.

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.
