Judul: Kajian dampak initial public offering terhadap economic value added PT Bank Tabungan Negara, Tbk
Abstrak: BTN Bank is a bank that focuses on housing loans. BTN Bank are fulfilling their IPO on December 27, 2009. In order to evaluate their success of the IPO, the performance seen based economic value added that BTN has been created. The aims of this research are: (1) analyze the growth of capital structure BTN Bank and COC (cost of capital) generated before and after the IPO, (2) analyze the financial performance of BTN Bank growth by comparing the value of economic value added (EVA) before and after the IPO, and (3) analyze the impact of the IPO to the cost of equity and the resulting impact on EVA (economic value added) Bank BTN. There are three result from this study. First, the percentage of the average amount of capital structure (long-term debt and equity) Bank BTN after IPO has discreas and the cost of capita Bank BTN after IPO has increase. Second, economic value added (EVA) of Bank BTN after IPO has decreased. Third, IPO of BTN Bank in 2009 resulted the value of cost of equity increases and it has significant effect on economic value added (EVA) Bank BTN after the IPO

Judul: Pengaruh initial public offering (IPO) terhadap kinerja keuangan pada PT Bank Jawa Barat dan Banten periode 2009-2010
Abstrak: Kebutuhan akan dana yang besar menginspirasi perusahaan menjual sebagian sahamnya di pasar modal untuk mendapatkan sumber dana baru dari publik atau yang dikenal dengan go public. Sejak 8 Juli 2010 Bank BJB sudah terdaftar di Bursa Efek Indonesia dengan opening price Rp 830,00 per saham dan ditutup dengan harga Rp 900,00 atau meningkat 50 persen dari harga Rp IPO Rp 600,00 per saham. Penelitian ini bertujuan untuk (1) Menganalisis perubahan struktur modal pra dan pasca IPO, (2) Menganalisis kesehatan perseroan pra IPO dengan analisis rasio keuangan, (3) Menganalisis kesehatan perseroan pasca IPO dengan analisis rasio keuangan, (4) Menganalisis pengaruh IPO terhadap kinerja keuangan perseroan. Data yang digunakan dalam penelitian ini hanya data sekunder baik bersifat kualitatif maupun kuantitatif. Data tersebut diperoleh dari studi pustaka, internet, jurnal, serta literatur-litertur terkait yang mendukung penelitian. Metode analisis datanya yaitu membandingkan kinerja keuangan perseroan pra IPO dengan pasca IPO. Analisis yang digunakan untuk mengetahui hal tersebut adalah dengan analisis rasio keuangan termasuk rasio CAMEL (Capital, Assets, Management, Earnings, Liquidity) di dalamnya. Penelitian dimulai dengan menganalisis perubahan struktur modal pra dan pasca IPO, lalu menganalisis kinerja keuangan pra dan pasca IPO dengan analisis rasio, seperti ROA, ROE, NPM, OPM, DER, PBV, EPS, PER, CAR, ATTM, NIM, BOPO, dan LDR. Setelah dianalisis kinerja keuangan pada masing-masing periode, selanjutnya penelitian dilanjutkan pada tahap perbandingan antara kinerja keuangan pra IPO dengan pasca IPO dengan menggunakan uji beda paired-sample t test.

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.
