Judul: Analisis Pengaruh Gaya Kepemimpinan terhadap Komitmen Organisasi Karyawan di PT Aspex Kumbong
Abstrak: This research was done in Aspex Kumbong Company which is the merger company between Panwell Industry Company Ltd. ( South Korea Company ) and Aspex Paper Indonesia Company. To improve productivity and achievement of organizational objectives, required management of human resource is needed. It can be done by leadership style and organizational commitment of employees. The results showed that the most dominant leadership style from the four situational leadership styles (telling, selling, participating, and delegating) is selling style. This research used descriptive analysis and SEM (software SmartPLS version 2.0). The perception of employees about the organization commitment with affective, normative, and continuance component deemed to be owned by the employees. Telling leadership style partially significant influence the organizational commitment component affective of employees at Aspex Kumbong Company. Delegating leadership style partially significant influence the organizational commitment component affective and continuance .

Judul: Analisis Pengaruh Budaya Organisasi terhadap Employee Engagement pada PT Aspex Kumbong
Abstrak: This thesis explained about how organizational culture affects employee engagement at Aspex Kumbong company. The research aims to find which value of five organizational culture variabels influenced employee engagement. Organizational culture (X) as independent variabel has five values such as work dicipline, loyalty, focus on target, innovation, and carefulness. All of the values was identified by delphi method. The employee engagement as dependent variable (Y) has 3 sub variables: vigor, dedication, and absorption. Primary data was collected with interviewing supervisors and giving questionary to Aspex Kumbong employees. Furthermore, the analysis of this research used descriptive analysis and structural equation modelling method, using microsoft excel and SmartPLS 2.0. The result showed that inovation influences absorption. Carefulness influence all of employee engagement variabels.

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.
