Judul: Pengaruh budaya kelas terhadap prestasi mahasiswa S1 Departemen Manajemen Fakultas Ekonomi dan Manajemen Institut Pertanian Bogor
Abstrak: Every organization has a culture which has been made to establish rules or guidelines in thought and action in achieving the set goals. This means that the growing and well maintained culture will be able to boost the existing individual towards a better development. Culture is one of the factors which can affect achievement and is expected to give positive influence, especially for students in the classroom. The purpose of this study is (1) identifying student’s achievement in Bogor Agricultural University (2) identifying the class culture in Bogor Agricultural University (3) analyzing the influence of class culture on the student’s achievement in Bogor Agricultural University. Sampling method that used in this research is purposive sampling. This research uses analysis of linear regression and processed by SPSS 16.0, Microsoft Excel 2007 and Minitab 14. The result of regression analysis showed that attitude and behaviour jointly and individually effective in improving student’s achievement.

Judul: Pengaruh Budaya Organisasi terhadap Kinerja Pegawai Sekolah Alam Bogor
Abstrak: Organizational culture has an important role in creating synergies within the organization goals. This goals can be achieved through one of the indicators of the performance of the employee. Then, the important role from organizational culture in improving the performance of employees is needed to create an overall organizational performance improvement. The purpose of this study is to analyze the influence of organizational culture on employee performance of Sekolah Alam Bogor. The data collected comes from primary and secondary data using interview, questionnaire, and observation techniques. The sampling technique was performed by nonprobability sampling with proportionate stratified sampling method. In this study, processing of the data conducted using descriptive method and Structural Equation Modelling (SEM)-Partial Least Square (PLS) method and processed using software smartPLS 2.0. The result of the evaluation study conducted by testing the measurement and structural evaluation tests lead to the conclusion that organizational culture has a positive and significant impact on employee performance of Sekolah Alam Bogor, this can be seen by the beta value of the construct of organizational culture on employee performance construct is 26,436 where the beta value is greater than 1,96.

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.
