Judul: Analisis CART Ketepatan Waktu Lulus Berdasarkan Karakteristik Mahasiswa di FEM dan FAPERTA
Abstrak: Graduate on time is one of the indicators of a student’s success in obtaining their undergraduate degrees. Previous study using CHAID (Chi-Squared Automatic Interaction Detection) method concluded that the highest probability classification for the IPB students who graduated on time comes from FEM and the lowest probability classification comes from FAPERTA. According to that, the purpose of this research is to identify the student’s characteristics as an indicator of the timeliness pass from the faculty with highest and lowest number of students who graduated on time using CART method. Tree classification of FEM classifies the characteristics of the highest students that graduated on time by 75% as the students from Departements of IE and MAN. Tree classification of FAPERTA classifies the characteristics of the highest students that graduated on time by 26.1% as the students from Departements of AGH and PTN and have GPA greater than 3.335. The classification tree of FAPERTA is better to estimate students who graduated on time with accuracy value 81.47% and the classification tree of FEM is better to estimate students who didn’t graduate on time with accuracy value 71.4%.

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.
