Judul: Strategi Pengembangan Usaha Tanaman Anggrek Vanda di Kelompok Tani Parakan Jaya Kota Tangerang Selatan
Abstrak: Orchid plant is one of the plants that has superiority of other types of flowers, such as it is has many variations and is widespread throughout the world. Production of orchids in Indonesia shows large numbers, which in 2012 contributed to the production of orchid fifth largest after chrysanthemum, tuberose, rose and jasmine. To that end, orchid commodity market can provide a bright prospect in the future. South Tangerang city is a center of orchid plant in Banten province, with one of the leading commodities in South Tangerang City is vanda orchids. The purpose of this study is to formulate alternative strategies based on the company's internal and external as well as establish the main strategies that had been applied by Parakan Jaya Farmer's Group. Based on the analysis of the matrix IE, Parakan Jaya Farmer's Group is in quadrant II, which suggests that Parakan Jaya Farmer's Group is well positioned and well grow. The SWOT analysis is done, resulting in seven alternative strategies that can be run by Farmers Group Parakan Jaya. QSPM analysis results indicate that the best strategy to be done by Parakan Jaya Farmer's Group is stepping up efforts for the promotion of business activities of Vanda orchids.

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.
