Judul: Partisipasi dan Dampak Program CSR PTPN VII terhadap Taraf Hidup Masyarakat Gunung Dempo Sumatera Selatan
Abstrak: One of responsibility to local communities, PT PTPN VII Persero has a corporate social responsibility program called UMKM program to empower the local communities. The purpose of this research was to describe the profile communities; describe the CSR program implementation in PTPN VII; analyze the level of stakeholder participation in the implementation of UMKM programs; analyze the impact of stakeholders participation in CSR programs on people's lives. The subject of this study was the Village of Mount Dempo, including local communities, government and corporate employees village. The method used in this research consisted of a quantitative method and supported by qualitative research using questionnaires and in-depth interview guide. The results of this research showed that every stakeholders had different types and degree of participation. The higher the level of participation of the communities involved in the implementation of the program, the higher the standard of living that is generated.

Judul: Hubungan Tingkat Partisipasi Peserta Program Csr Pt. Pertamina Dengan Tingkat Taraf Hidup Masyarakat Desa Karangsong
Abstrak: Corporate Social Responsibility (CSR) merupakan wujud kepedulian dan tanggung jawab sosial perusahaan kepada lingkungan dan masyarakat. PT. Pertamina merupakan salah satu perusahaan yang telah melaksanakan CSR guna menunjang operasionalisasi perusahaan. Penelitian ini bertujuan untuk menganalisis hubungan tingkat partisipasi dengan keberhasilan program, hubungan keberhasilan program dengan taraf hidup peserta dan hubungan partisipasi dengan taraf hidup peserta program. Pendekatan yang digunakan dalam penelitian ini adalah mengombinasikan pendekatan kuantitatif dengan pendekatan kualitatif. Hasil penelitian menunjukkan terdapat hubungan lemah antara partisipasi dengan keberhasilan program, tidak terdapat hubungan antara tingkat keberhasilan program dengan taraf hidup, serta tidak terdapat hubungan antara tingkat partisipasi dengan taraf hidup peserta program.

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.
