Judul: Faktor-Faktor yang Memengaruhi Keputusan Masyarakat Kampus terhadap Produk Pembiayaan (Studi Kasus: BPRS Botani IPB University)
Abstrak: BPRS Botani merupakan BPRS yang sebagian besar sahamnya dimiliki oleh IPB University. Berdasarkan data, nasabah yang berasal dari masyarkat kampus hanya 8,68 persen dari total populasi. Penelitian ini bertujuan untuk menganalisa faktor-faktor yang memengaruhi keputusan masyarakat IPB University terhadap produk pembiayaan BPRS Botani dengan sampel sebanyak 100 responden. Metode yang digunakan adalah analisis deskriptif dan analisis regresi logistik. Hasil penelitian menunjukkan religiusitas, pengetahuan tentang perbankan syariah, pengetahuan tentang BPRS Botani, biaya jasa berpengaruh signifikan positif sedangkan tingkat margin atau harga berpengaruh signifikan negatif terhadap pengambilan keputusan menggunakan produk pembiayaan BPRS Botani.

Judul: Faktor-faktor yang Memengaruhi Preferensi Mahasiswa IPB Terhadap Tabungan Syariah
Abstrak: Islamic banking is one of the financial institutions that are being developed at this time. Compared with the conventional banking customers who have stood since a long time time in Indonesia, Islamic banking customers is still relatively small. One of the huge potential for Islamic banking market is college students. Logistic regression method used in this study to analyze the factors that influence IPB students in choosing a savings. Descriptive analysis method used to analyze the student knowledge of sharia savings, the student confidence of sharia savings, and the student assessment against the facility of sharia savings. The data used in this study are primary data taken through an online questionnaire and secondary data taken from the literature. The result showed that the student knowledge of sharia savings, the student confidence of sharia savings, and student gender are factors that most influence students in choosing sharia savings. The result by descriptive analysis method showed that the student knowledge of sharia savings, the student confidence of sharia savings, and the student assessment against the facility of sharia savings are in good categories.

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.
