Judul: Analisis Pengaruh dan Strategi Green Marketing terhadap Keputusan Pembelian Konsumen Pepaya Callina
Abstrak: The emergence of awareness of environmental problems triggered the industrial world for marketing concept that puts the present environmental issues (green marketing). The purpose of this study is to (1) identify the characteristics Callina papaya consumers (2) Identify the aspects that has relationship with characteristics of Callina papaya consumer (3) Identify the priority strategies to increase the competitiveness that influence the consumer purchasing decisions. The characteristics of Callina papaya consumer at dominated by women who work as housewives, have middle income upward, above the 31 years old, and the last titled education scholar. Processing use Cross Tabulations there are some relations, such as relation between the gender with knowledge about Callina papaya, relation between age with opinions about fruit flesh and the knowledge about production process, relation between income with a willingness to pay higher, relation between educational with willingness to pay higher, and relation between occupations with opinions about delicious papaya. The opinion of some experts through interviews processed using the ANP in order to obtain priority strategies that should be implemented in advance of the cluster is the product quality of product attributes, the product of cluster marketing mix, and retail of cluster actors.

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.
