Judul: Competitiveness Analysis of Indonesian Pineapple Exports to the United Arab Emirates
Abstrak: Nanas Indonesia mempunyai jumlah produksi yang terus meningkat setiap tahunnya. Sebagian besar nanas Indonesia diekspor ke Uni Emirat Arab. Namun, jumlah nanas yang diekspor ke Uni Emirat Arab masih jauh lebih rendah dibandingkan negara pesaingnya, yaitu Filipina. Penelitian ini bertujuan (1) menganalisis keunggulan komparatif nanas Indonesia di Uni Emirat Arab dan (2) menganalisis keunggulan kompetitif nanas Indonesia di Uni Emirat Arab. Metode analisis yang digunakan dalam penelitian ini adalah Revealed Comparative Advantage untuk menganalisis keunggulan komparatif nanas di Uni Emirat Arab, metode Export Product Dynamic dan Diamond’s Porter untuk menganalisis keunggulan kompetitif nanas di Uni Emirat Arab. Hasil penelitian menunjukkan bahwa Indonesia memiliki keunggulan komparatif di Uni Emirat Arab dengan nilai rata-rata RCA > 1. Nanas Indonesia memiliki keunggulan kompetitif. Nanas Indonesia berada pada posisi pasar Rising Star. Analisis Diamond’s Porter menunjukkan bahwa banyak faktor kelemahan dalam ekspor nanas Indonesia, namun terdapat dua faktor pendukung yang memiliki keunggulan kompetitif, yaitu peran pemerintah dan peran kesempatan, Indonesia’s pineapples have a production that continues to increase every year. Most of Indonesia's pineapples are exported to the United Arab Emirates. However, the amount of pineapple exported to the United Arab Emirates is still much lower than its competitor, the Philippines. This study aims to (1) analyze the comparative advantages of Indonesian pineapples in the United Arab Emirates and (2) analyze the competitive advantages of Indonesian pineapples in the United Arab Emirates. The analytical method used in this study is Revealed Comparative Advantage to analyze the comparative advantage of pineapples in the United Arab Emirates, the Export Product Dynamics, and Diamond's Porter to analyze the competitive advantages of pineapples in the United Arab Emirates. The results showed that Indonesia has a comparative advantage in the United Arab Emirates with an average value of RCA > 1. Indonesian pineapple has a competitive advantage. Indonesian pineapple is in the Rising Star market position. Diamond’s Porter analysis shows that there are many factors of weakness in Indonesia's pineapple exports, but there are two supporting factors that have a competitive advantage, namely the role of government and the role of opportunity.

Judul: Analysis of Indonesia's Nutmeg Export Performance and Competitiveness.
Abstrak: Pala merupakan komoditas unggulan ekspor Indonesia. Indonesia menjadi eksportir terbesar di dunia pada komoditas pala dengan HS 090811. Meskipun demikian tetap diperlukan inovasi serta pengembangan sehingga dapat meningkatkan nilai ekspor. Penelitian ini menganalisis Kinerja dan Daya Saing Ekspor Pala Indonesia ke negara tujuan utama dengan menggunakan data dari 9 negara, yaitu Vietnam, Amerika Serikat, Belanda, Jepang, Jerman, Italia, Singapura, India, dan Korea Selatan selama periode 2012-2018. Metode analisis yang digunakan yaitu RCA, EPD, X-Model, dan regresi data panel. Hasil RCA menunjukkan bahwa ekspor pala Indonesia pada semua negara tujuan memiliki daya saing yang kuat serta keunggulan komparatif. Analisis EPD menunjukkan Amerika Serikat dan India berada pada posisi Rising Star, Falling Star pada Vietnam, Jepang, Jerman, Italia, dan Singapura. Kemudian Retreat pada negara Belanda dan Korea Selatan. Hasil Model-X menunjukkan potensi pengembangan pasar ekspor pala Indonesia optimis, potensial, dan kurang potensial. Regresi data panel menunjukkan harga ekspor, nilai tukar riil, dan TBT berpengaruh signifikan terhadap nilai ekspor pala Indonesia., Nutmeg is Indonesia's leading export commodity. Indonesia is the world's largest exporter of nutmeg with HS 090811. Nevertheless, innovation and development are still needed so that it can increase export value. This study analyzes the performance and competitiveness of Indonesia's nutmeg exports to major destination countries using data from 9 countries, namely Vietnam, the United States, the Netherlands, Japan, Germany, Italy, Singapore, India and South Korea during the 2012-2018 period. The analytical methods used are RCA, EPD, X-Model, and panel data regression. The RCA results show that Indonesia's nutmeg exports to all destination countries have strong competitiveness and comparative advantages. EPD analysis shows the United States and India are in the Rising Star, Falling Star positions in Vietnam, Japan, Germany, Italy, and Singapore. Then Retreat to the Netherlands and South Korea. X-Model shows that the potential development of the Indonesian nutmeg export market is optimistic, potential, and less potential. Panel data regression shows that export prices, real exchange rates, and TBT have a significant effect on the export value of Indonesian nutmeg.

Judul: Penyelesaian Masalah Rotasi Aliran Fluida Kental Von Karman Menggunakan Metode Homotopi
Abstrak: Von Karman equation is an equation that describes fluid viscous flow induced by infinite disk rotation. By assuming steady flow and laminar, viscous incompressible fluid flow is represented in Von Karman equation by an angular velocity and the vertical direction velocity as the independent variables. Von Karman equation is a nonlinear problem that is solved using the homotopy method. The use of homotopy method is done by defining an homotopy function that requires auxiliary parameters to control the convergent region of the solution. The solution is a recursive formula with given initial conditions. Using software based-functional shows that velocity components converge to a value.
