Judul: Analisis Strategi Pemasaran Mangga Gedong Gincu Kabupaten Indramayu untuk Pusat Perbelanjaan di Kota Besar (Kasus CV Damardjati, Kecamatan Jatibarang, Kabupaten Indramayu)
Abstrak: Gedong Gincu Mango is one of the special commodities in Indonesia with economic value. CV Damardjati is a supplier of Gedong Gincu Mango with supermarket distribution area limited in Indramayu Regency and Cirebon City, therefore they have not used the opportunity to get higher selling prices in the big city supermarket. This research was aimed to analyze fruit’s marketing mix and purchasing order of Gedong Gincu Mango in supermarkets and the marketing startegy of CV Damardjati’s Gedong Gincu Mango for the supermarket in big city. Observation and interview were conducted toward the director of CV Damardjati and the supervisors of supermarket and fruit shops. Strategies resulted by SWOT matrix analysis and explained in the two years strategy architecture are: applying the product positioning strategy on the Gedong Gincu Mango by adding brand, label and packaging attribute; enlarge its distribution area in the big city supermarket; and revitalitation promotion by selling promotion and direct marketing. Therefore, the company must built partnership to make Indramayu Regency’s Gedong Gincu Mango competitive in Big City Supermarket

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.
