Judul: Analisis Keputusan Pembelian Daging Sapi oleh Konsumen Rumah Tangga (Kasus: Hipermarket Giant Taman Yasmin Bogor)
Abstrak: The beef price rising affected other meat products purchasing, such as chicken and fish. The increasing of beef price also happened at the modern market in Bogor. This study analyses the process of beef purchasing by consumer, interest level and performance attributes of beef at Giant Taman Yasmin. By using Costumer Satisfaction Index (CSI) and Importance Performance Analysis (IPA) methods, the results are the consumer satisfaction rate of beef sales at Giant Taman Yasmin is satisfied, where consumers have felt the performance of beef in Giant Taman Yasmin has good, but there is still need to be improved, and the price attribute is the first priority which has to be improve

Judul: Analisis Proses Keputusan Pembelian Daging Ayam Ras Dan Implikasi Terhadap Bauran Pemasaran (Studi Kasus Pasar Baru Bogor Dan Giant Botani Square).
Abstrak: Produksi terbesar daging ternak di Kota Bogor tahun 2014 berasal dari komoditi ayam ras. Hal ini mengindikasikan adanya konsumsi yang tinggi pula sehingga pemasar menjual daging ayam untuk memenuhi kebutuhan masyarakat. Pasar Baru Bogor dan Giant Botani Square menyediakan daging ayam ras dengan tingkat harga bersaing dan karakternya masing-masing. Tujuan dari penelitian ini adalah menganalisis karakteristik konsumen, proses keputusan pembelian, tingkat kepuasan dan implikasi terhadap bauran pemasaran dari konsumen daging ayam di kedua pasar tersebut. Data dikumpulkan dari 100 responden yang dipilih dengan metode convenience. Respon konsumen mencakup harapan dan kinerja daging ayam diukur dengan skala Likert. Data dianalisis dengan menggunakan metode deskriptif, Chi-square, Mann-Whitney, Importantce Performance Analysis (IPA) dan Customer Satisfaction Index (CSI). Hasil menunjukkan bahwa terdapat perbedaan karakteristik konsumen dan proses pengambilan keputusan di kedua pasar. Hasil CSI untuk konsumen di Giant Botani Square yaitu 81.72 dan untuk yaitu Pasar Bogor yaitu 74.42 persen. Kesimpulannya adalah Pasar Baru Bogor dan Giant Botani Square telah dapat memuaskan konsumen daging ayam.

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.
