Judul: Export Flow and Competitiveness  of Processed Coconut Oil in East Asia and North America
Abstrak: Minyak kelapa olahan adalah salah satu komoditas sektor industri pengolahan nonmigas dan termasuk komoditas lemak dan minyak hewan/nabati. Kawasan tujuan utama Indonesia adalah Asia Timur dan Amerika Utara. Cina dan Amerika Serikat (AS) adalah negara tujuan utama yang tidak memproduksi minyak kelapa olahan, tetapi menjadi eksportir di negara lain. Hal ini mengindikasikan produk yang diekspor kedua negara adalah hasil impor dari negara lain, seperti Indonesia. Penelitian ini bertujuan untuk menganalisis aliran ekspor dan daya saing minyak kelapa olahan Indonesia di Asia Timur dan Amerika Utara dengan metode analisis deskriptif, RCA, AR, EPD, dan X-Model. Hasil penelitian menunjukkan, minyak kelapa olahan Indonesia yang diekspor ke kedua kawasan diperdagangkan kembali oleh negara importir. Hasil RCA menunjukkan Indonesia berdaya saing komparatif di setiap negara tujuan. Hasil AR menunjukkan Indonesia mampu merebut pasar di setiap negara tujuan. Hasil EPD menunjukkan Indonesia berada di posisi retreat di Korea Selatan dan rising star di Cina juga AS. Hasil X-Model menunjukkan Indonesia memiliki potensi pasar kurang potensial di Korea Selatan dan potensi pasar optimis di Cina juga AS., Processed coconut oil is one of the commodities in the non-oil and gas processing industry sector and included in the fat and animal/vegetable oil commodity. The main destination areas for Indonesia’s are East Asia and North America. China and the United States (US) are the main export destination countries that do not produce processed coconut oil, yet become exporters in other countries. This indicates that the product exported by both countries is imported from other countries, such as Indonesia. This research aims to analyze the export flow and competitiveness of Indonesian processed coconut oil in East Asia and North America using descriptive analysis methods, RCA, AR, EPD, and X-Model. The research results show that Indonesian processed coconut oil exported to both areas is being traded again. The RCA result shows that Indonesian processed coconut oil is comparatively competitive in each destination country. The AR result shows that Indonesia can seize the export market for processed coconut oil in each destination country. The EPD result shows that Indonesia is in a retreat position in South Korea and in a rising star position in China and US. The X-Model result shows that Indonesia has less potential market in South Korea and optimistic potential market in China and the US.

Judul: Analysis of Competitiveness, Potential, and Factors Affecting Indonesia's Crude Coconut Oil Exports in Main Destination Countries
Abstrak: Minyak kelapa mentah merupakan produk turunan kelapa yang memiliki nilai ekonomi tinggi dan berkontribusi besar terhadap keseluruhan produk ekspor kelapa. Indonesia menjadi negara eksportir minyak kelapa mentah terbesar kedua di dunia, namun volume ekspor minyak kelapa mentah Indonesia ke negara tujuan utama menurun dalam beberapa tahun terakhir. Penelitian ini bertujuan untuk menganalisis keunggulan komparatif dan kompetitif minyak kelapa mentah Indonesia di negara tujuan utama, potensi ekspor minyak kelapa mentah serta faktor-faktor yang memengaruhi ekspor minyak kelapa mentah Indonesia di negara tujuan utama. Metode analisis yang digunakan, yaitu Revealed Comparative Advantage (RCA), Export Dynamic Product (EPD), X-Model, dan regresi data panel. Hasil estimasi RCA dan EPD menunjukkan minyak kelapa mentah Indonesia berdaya saing secara komparatif di Belanda, Malaysia, dan Amerika Serikat serta berdaya saing kompetitif di Amerika Serikat yaitu pada posisi rising star. Hasil estimasi X-Model menunjukkan minyak kelapa mentah Indonesia memiliki pasar optimis di negara Amerika Serikat. Hasil estimasi model menunjukkan bahwa variabel harga ekspor CCO Indonesia berpengaruh negatif dan signifikan, sedangkan harga ekspor CCO Filipina dan keterbukaan perdagangan berpengaruh positif signifikan terhadap volume ekspor minyak kelapa mentah Indonesia., Crude coconut oil (CCO) is coconut derivative products that has high economic value and contributes greatly to the overall export of coconut products. Indonesia is the second largest exporter of CCO in the world, but the volume of Indonesia's CCO exports to major destination countries has declined in recent years. This research aims to analyze the comparative and competitive advantages of Indonesia's CCO in the main destination country, the export potential of CCO, and the factors that affect Indonesia's CCO exports in the main destination country. The analysis methods used RCA, EPD, X-Model, and panel data model. The results of RCA and EPD estimates show that Indonesia's CCO is comparatively competitive in Netherland, Malaysia, and United States and also is competitively competitive in the United States, namely in the rising star position. X-Model estimates show that Indonesia's CCO has an optimistic market in the United States. The estimation results of the model show that the variable CCO export price for Indonesia has a negative and significant effect, while the export price for CCO for the Philippines and trade openness has a significant positive effect on the export volume of Indonesia's CCO.

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.
