Judul: Perilaku Konsumen dalam Aktivitas Pembelian Telur Omega-3 di Beberapa Supermarket di Kota Bogor
Abstrak: Omega-3 egg is egg that contains more omega-3 than conventional egg but still not too popular in society. The aim of this study was to identify consumer behavior towards purchasing activity omega-3 egg in several categories supermarket in Bogor City. This study conducted in 26 August – 26 September 2013 in 6 supermarkets namely Ramayana Tanah Sareal, Lotte Mart Cimanggu, Yogya Cimanggu, Giant Yasmin, Giant Botani Square and Superindo Jembatan Merah. There were 60 selected samples were divided 10 samples supermarket-1. This study used non randomized sampling method. Consumer in Bogor city have known the information about omega-3 egg from print media, buy it from supermarket purpose to consumed, all family member consume but not rutine, amount of eggs 10 eggs purchase-1, brown egg shell is preferred, the most preferred packaging was plastic mica, egg price 2.500 rupiah egg-1 and respondents thought that omega-3 egg price expensive.

Judul: Persepsi Masyarakat terhaciap Telur Ayam Omega-3 eli Bogar
Abstrak: Omega-3 egg is modificated egg with higher nutrition content than conventional egg and has a lot benefits for health and intelligence. This study aimed to identify public perception on omega-3 egg and its benefits by dividing them into several categories. There were 50 selected sample of respondents having knowledge about omega-3 eggs which are also divided into five characteristic. There are pregnant women, infants mother, educated at least bachelor people, disease susceptible age (45-60) years, and the elderly (> 60) years. Respondents were given eleven questions about the advantages of omega-3 egg and five choices of virtues in consuming omega-3 eggs. The result indicated that all categories of respondents agree with all the advantages of omega-3 eggs. While, the virtue in consuming omega-3 eggs are chosen selected by respondents were toddlers intelligence. In conc1usion,the study has showed that society in Bogor area received omega-3 egg products as adventageous products for health and brain intelligence

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.
