Judul: Analisis Tingkat Kepuasan Konsumen di Restoran Gumati Paledang Bogor.
Abstrak: Pada era globalisasi ini, kebiasaan masyarakat untuk makan di luar rumah membuat keberadaan restoran semakin memberikan kemudahan bagi masyarakat perkotaan yang cenderung sangat sibuk dan tidak punya waktu luang untuk menyediakan makanan sendiri. Berkembangnya usaha restoran di Bogor menyebabkan persaingan yang begitu ketat baik dalam hal produk, pelayanan, suasana restoran, lokasi maupun fasilitas pendukung. Persaingan tersebut mengharuskan para pelaku bisnis makanan menerapkan strategi pasar yang menitikberatkan kepada kepuasan konsumen. Penelitian ini bertujuan untuk mengidentifikasi karakteristik konsumen dan proses pengambilan keputusan pembelian, serta menganalisis tingkat kepuasan konsumen. Data yang digunakan merupakan data primer diperoleh dari hasil kuesioner terhadap 100 responden diolah menggunakan alat analisis deskriptif dan analisis Customer Satisfaction Index (CSI) dan Importance Performance Analysis (IPA). Hasil penelitian didapatkan pada proses pengambilan keputusan suasana dan pemandangan restoran menjadi atribut yang sangat dipertimbangkan. Secara keseluruhan berdasarkan Customer Satifaction Index (CSI) diperoleh nilai 79.14 persen yang artinya konsumen sudah merasa puas dengan kinerja atribut restoran.

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.
