Judul: Penilaian Konsumen Terhadap Atribut Restoran Oriental Food (Kasus Restoran Makisu dan Shanghai Garden di Gedung Bursa Efek Indonesia)
Abstrak: Seiring peningkatan kegiatan perekonomian di Indonesia, terjadi perubahan gaya hidup pada masyarakat yang bekerja di Jakarta. Salah satunya adalah perubahan pola makan. Pergeseran pola konsumsi makanan dari makanan tradisional ke makanan modern disebabkan oleh (1) peningkatan pendapatan, (2) perubahan gaya hidup, (3) mobilitas yang tinggi di perkotaan, sehingga masyarakat cenderung lebih memilih makanan modern. Intensitas kerja karyawan di Jakarta yang relatif tinggi dan waktu makan siang karyawan yang sangat terbatas mendorong karyawan mendapatkan makanan untuk makan siang yang bersifat cepat, praktis dan nyaman. Kondisi ini merupakan alasan utama bagi pengusaha untuk membuka restoran modern. Bisnis restoran yang sedang berkembang pesat di Indonesia adalah bisnis waralaba yang cepat saji (fast food). Peningkatan pertumbuhan waralaba asing dan lokal di Indonesia setiap tahunnya menyebabkan persaingan yang semakin ketat antara pelaku bisnis restoran. Persaingan mendorong pelaku bisnis untuk terus membangun dan mempertahankan kesetiaan pelanggan. Sehingga setiap pelaku bisnis harus menempatkan orientasi pada kepuasan pelanggan sebagai tujuan utama. Restoran Makisu dan Shanghai Garden adalah salah satu pelaku pada bisnis tersebut. Tujuan penelitian adalah (1) mengidentifikasi keputusan pembelian konsumen terhadap Restoran Makisu dan Shanghai Garden dan (2) menganalisis preferensi konsumen terhadap pemilihan Restoran Makisu dibandingkan dengan Restoran Shanghai Garden.

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.
