Judul: Analysis  of  competitiveness  and  determinants  of  indonesian cpo export to india and netherlands
Abstrak: Sejak tahun 2006, Indonesia menjadi produsen CPO terbesar di dunia. Namun, krisis ekonomi global menyebabkan penurunan laju ekspor CPO dunia dalam beberapa tahun terakhir. Selain itu terdapat hambatan non tarif berupa black campaign terhadap di Eropa. Penelitian ini dilakukan untuk menganalisis daya saing dan faktor-faktor yang mempengaruhi ekspor CPO ke India dan Belanda. Berdasarkan hasil analisis Revealed Comparative Advantage (RCA), CPO Indonesia memiliki daya saing yang sangat kuat di pasar India dan Belanda. Hasil analisis Ordinary Least Square(OLS) menunjukkan ekspor CPO Indonesia ke India dipengaruhi oleh semua variabel dependen (harga ekspor CPO, harga minyak kedelai, kurs rupiah terhadap dollar, nilai RCA CPO Indonesia di India, dan pajak progresif). Sedangkan ekspor CPO Indonesia ke Belanda dipengaruhi oleh harga minyak kedelai dan pajak progresif., Since 2006, Indonesia has become the largest CPO producer in the world. However, global economic crisis caused decreasing in Indonesian CPO export in recent years. In addition, there is non tariff barrier, black campaign against Indonesia CPO in Europe. This study aims to analyze the competitiveness and the determinant of Indonesian CPO export to India and Netherlands. Based on RCA analysis, Indonesia CPO has high comparative advantage in India and Netherlands markets. The result of OLS analysis showed that the export of Indonesian CPO to India was affected significantly by all dependent variables (export price of CPO, price of soybean oil, exchange rate, RCA index, and progressive advalorem tax). Whereas, the export of Indonesian CPO to Netherlands was affected significantly by price of soybean oil, and progressive advalorem tax.

Judul: Competitiveness of Indonesia Crude Palm Oil (CPO) Exports in Main Destination Countries
Abstrak: Kelapa sawit adalah salah satu komoditas sub sektor perkebunan yang memiliki peran penting dalam perekonomian nasional. Kelapa sawit menghasilkan produk utama yaitu CPO (Crude Palm Oil). Indonesia merupakan negara dengan produksi CPO terbesar di dunia. Seiring dengan pergeseran konsumsi minyak nabati dunia kepada minyak sawit, volume ekspor CPO di pasar dunia juga semakin meningkat. Adanya kebijakan bea keluar tahun 2008 menyebabkan perubahan komposisi ekspor produk kelapa sawit yang awalnya berupa minyak sawit mentah menjadi produk turunannya. Malaysia merupakan negara pesaing yang melakukan ekspor CPO di dunia. Negara tujuan utama ekspor CPO Indonesia adalah India, Belanda, Malaysia, Italia, dan Singapura. Tujuan penelitian ini adalah menganalisis kinerja ekspor CPO Indonesia di pasar dunia dan menganalisis daya saing ekspor CPO Indonesia di pasar dunia terutama negara tujuan utama. Metode yang digunakan dalam penelitian ini adalah Revealed Comparative Advantage (RCA) untuk menghitung keunggulan komparatif CPO Indonesia dan Market Share Index (MSI) untuk menghitung pangsa pasar CPO Indonesia di negara tujuan utama dibandingkan dengan negara pesaing. Hasil dari analisis RCA menunjukkan bahwa CPO Indonesia memiliki keunggulan komparatif di negara tujuan utama ekspor sedangkan analisis MSI menunjukkan jika CPO Indonesia memiliki pangsa pasar yang besar di India, Italia, dan Singapura. Hasil dari kedua analisis tersebut menunjukkan bahwa Indonesia memiliki daya saing yang kuat di negara tujuan ekspor., Oil palm is one of the plantation sub-sector commodities that has an important role in the national economy. Palm oil produces the main product, namely CPO (Crude Palm Oil). Indonesia is a country with the largest CPO production in the world. In line with the shift in world vegetable oil consumption to palm oil, the volume of CPO exports on the world market is also increasing. The export duty policy in 2008 caused a change in the export composition of palm oil products from crude palm oil to its derivative products. Malaysia is a competitor country that exports CPO in the world. The main export destinations for Indonesian CPO are India, the Netherlands, Malaysia, Italy and Singapore. The purpose of this research is to analyze the performance of Indonesian CPO exports in world markets and to analyze the competitiveness of Indonesian CPO exports in world markets, especially the main destination countries. The methods used in this research are Revealed Comparative Advantage (RCA) to calculate the comparative advantage of Indonesian CPO and Market Share Index (MSI) to calculate the market share of Indonesian CPO in the main destination countries compared to competing countries. The results of the RCA analysis show that Indonesian CPO has a comparative advantage in the main export destination countries, while MSI's analysis shows that Indonesian CPO has a large market share in India, Italy and Singapore. The results of the two analyzes indicate that Indonesia has strong competitiveness in export destination countries.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
