Judul: Dampak Landreform Dari Bawah (By Leverage), Dan Arah Transfer Manfaat Dalam Kebijakan Program Pembaruan Agraria Nasional (Studi Kasus Organisasi Tani Lokal Banjaranyar Ii Desa Banjaranyar Dan Organisasi Tani Lokal Pasawahan Ii Desa Pasawahan Kecamatan Banjarsari, Kabupaten Ciamis, Jawa Barat)
Abstrak: To create an equity land structure, it’s necessary to change the agrarian structure to increase community wealth. It called landreform. The purpose of this research was to identification land conflict, processes in implementation landreform by leverage, implementation of National Agrarian Reform Program (PPAN), and trajectories of change and reform in land policies in OTL Banjaranyar II and OTL Pasawahan II. The number of respondents in this research were 30 people for each OTL with stratified random sampling. In general, the implementation of land occupation at these place called landreform by leverage integration (at OTL Banjaranyar II) and annexation (at OTL Pasawahan II) type. National Agrarian Reform Program was implemented at Banjaranyar, whereas at Pasawahan it still on process. Impelentation of landreform by leverage and the National Agrarian Reform Program gave social impact, the change of agrarian structure and wealth for people at these place. The trajectories of change and reform in land policies is redistribution.

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.
