Judul: Analysis of Indonesian Turmeric Competitiveness in Main Destination Countries
Abstrak: Indonesia sebagai salah satu produsen kunyit terbesar di dunia mempunyai potensi untuk berperan di pasar kunyit dunia sehingga mampu meningkatkan daya saing di pasar dunia. Penelitian ini bertujuan untuk menganalisis daya saing komparatif dan kompetitif ekspor kunyit Indonesia di negara tujuan utama. Metode yang digunakan adalah Revealed Comparative Advantage (RCA) dan Export Product Dynamic (EPD). Hasil analisis kunyit Indonesia berdaya saing komparatif kuat pada empat negara tujuan yaitu India, Amerika, Singapura, Korea Selatan, namun pada pasar Malaysia kunyit Indonesia tidak memiliki daya saing komparatif yang kuat. Analisis EPD menunjukkan bahwa kunyit Indonesia berada pada posisi Rising Star pada negara India dan Malaysia, sedangkan di negara Singapura dan Korea Selatan berada pada posisi Falling Star, dan Amerika Serikat berada pada posisi Lost Opportunity.

Judul: Analysis of Competitiveness and Factors Affecting Indonesian Cinnamon Powder Exports to  Main Destination Countries
Abstrak: Indonesia merupakan negara eksportir terbesar bubuk kayu manis (kode HS 090620) di dunia. Sejak 2012, nilai ekspor bubuk kayu manis Indonesia lebih tinggi dibandingkan dengan nilai ekspor kayu manis mentah. Namun nilai ekspor tersebut masih berfluktuatif dan cenderung menurun dibandingkan negara pesaing seperti Vietnam. Penelitian ini bertujuan untuk menganalisis daya saing, cakupan pemberlakuan NTM, dan faktor-faktor yang mempengaruhi ekspor bubuk kayu manis Indonesia ke 9 negara tujuan utama periode 2011-2020. Metode analisis yang digunakan pada penelitian ini adalah metode RCA, EPS, X-Model, pendekatan inventory, dan regresi data panel. Metode RCA menunjukkan bahwa bubuk kayu manis Indonesia memiliki daya saing yang kuat di 9 negara tujuan. Metode EPD menunjukkan posisi pasar retreat, falling star, dan rising star. X-Model menunjukkan pengembangan pasar optimis ke Swedia, potensial ke Belanda, Vietnam, Kanada, dan Jerman, sedangkan kurang potensial ke Amerika Serikat, Jerman, Brazil, dan Australia. Hasil regresi data panel menunjukkan harga ekspor, nilai tukar, LPI Indonesia, GDP riil per kapita negara tujuan, dan CR SPS memiliki pengaruh signifikan positif. Sedangkan dummy pandemi Covid-19 dan CR TBT memiliki pengaruh signifikan negatif., Indonesia is the largest exporter of cinnamon powder (HS code 090620) in the world. However, the export value is still fluctuating and tends to decrease compared to competing countries such as Vietnam. This study aims to analyze the competitiveness, scope of application of the NTM, and the factors that influence the export of Indonesian cinnamon powder to 9 main destination countries for the period 2011-2020. The analytical methods used in this research are RCA, EPD, X Model, inventory approach, and panel data regression. The RCA method shows that Indonesian cinnamon powder has strong competitiveness in 9 destination countries. The EPD method shows the retreat, falling star, and rising star market positions. The X-Model shows an optimistic market development to Sweden, potential to the Netherlands, Vietnam, Canada, and Germany, while less potential to the United States, Germany, Brazil, and Australia. The results of panel data regression show that export prices, exchange rates, LPI Indonesia, real GDP per capita of destination countries, and CR SPS have a significant positive effect. Meanwhile, the Covid-19 pandemic dummy and CR TBT had a significant negative effect.

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.
