Abstrak: Plant ornamental horticulture is one commodity that has considerable contribution in the development of agriculture in Indonesia. Ornamentals (floriculture) is an agribusiness product are now being develop. In Indonesia ornamental plants can grow well, but cultivated ornamental plants adapted to the natural condition of each region. One of the areas in Indonesia, which became centers of ornamental plants in West Java. West Java itself has several centers of ornamental plants such as Bandung, Cianjur, Sukabumi, Karawang, Bekasi, Garut, Depok, and Bogor. Ornamental plants are cultivated in the centers of ornamental plants are composed of various types ranging from ornamental plants cut flowers, ornamental plants cut leaves, leaves of ornamental plants in pot, and ornamental plants in the garden. Godong Ijo Nursery is one of the companies engaged in the agribusiness plants located at KM 10 Jalan Raya Cinangka, Sawangan District, Depok Municipality. Godong Ijo Nursery incorporated in KUBA (Agribusiness Business Group) under the auspices of the department of agriculture in Depok. With a land area of ±2.5 hectares Godong Ijo Nursery has grown with the type of commodities that selenium. Total weighting on the IFE matrix totaled 3.331, which mean the company’s internal situation Godong Ijo is at a level above the average. EFE matrix weighting the total amounted to 3.296, which mean the company able to take advantage of opportunities and avoid threats well.

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.
