Judul: Efektivitas Sistem Pengembangan Karir dalam Meningkatkan Employee Engagement pada PT Pupuk Kaltim
Abstrak: Employee engagement is the one of the important factor that is currently widely used by companies to increase productivity. Employees will be engaged if the company can manage well and give a support to employees, one of them through career development system. The purposes of this study are to know employees’ perception about the career development system and employee engagement in PT Pupuk Kaltim, and analizing the effectiveness of the career development system in improving employee engagement. Data that used in this study are primary data and secondary data. This study uses analysis of linear regression and processed by SPSS 16.0 and Microsoft Excel 2010. Employees’ perception about the career development system and employee engagement showed that career development system has been done well and employees has high level of engagement. The result of regression analysis showed that competency assessment and qualification jointly effective in improving employee engagement and only competency assessment individually effective in improving employee engagement.

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.
