Judul: Pemimpin Adat dan Pembangunan Partisipatif di Kasepuhan Ciptagelar Sukabumi
Abstrak: Pemimpin adat adalah pemimpin yang dipilih berdasarkan hukum adat. Pemimpin adat bertanggung jawab terhadap kelangsungan hukum adat dan kesejahteraan masyarakatnya. Peranan pemimpin adat merupakan sosok yang mampu mengorganisasikan pengikutnya untuk ikut berpartisipasi dalam kegiatan. Ditunjukkan pemimpin adat mampu menerjemahkan kepentingan masyarakat. Masyarakat percaya kepada pemimpin adat, sehingga masyarakat mau ikut berpartisipasi dalam kegiatan yang diarahkan oleh pemimpin adat. Partisipasi mempunyai hubungan pengaruh dengan kesejahteraan. Partisipasi yang tinggi menyebabkan kebutuhan masyarakat dapat dipenuhi yang searah dengan tingkat kesejahteraan. Penelitian ini dilakukan untuk melihat hubungan antara peranan pemimpin adat, partisipasi dan kesejahteraan masyarakat. Metode yang digunakan merupakan metode survey. Hasil penelitian menunjukkan bahwa semakin baik peranan pemimpin, maka akan semakin tinggi partisipasi. Selanjutnya semakin tinggi partisipasi masyarakat, maka akan semakin tinggi kesejahteraan masyarakat.

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.
