Abstrak: General objective of this study is to analyse Community’s Food Preference and nutritional carrying capacity in the direction of food diversification achievement in Bogor Regency. The spesific objectives are (1) to analyse individual characteristic sample i.e. last education, salary per capita, expenditure per capita, (2) to identify environment characteristic i.e. number of family, job, information from mass media, and production, (3) to identify food preference, (4) to analyse the correlation between food preference with individual and environment characteristic, (5) to analyse local food’s production and preference. Design of this study was cross sectional study with cluster analysis and simple random sampling. Number of sample is 106 for two region characteristics. Data were analized by Microsoft Excel and SPSS 16.0 for Window. Food preference of Bogor Regency community shows that almost sample like to 9 food groups in Desireable Dietary Pattern. The reason of this food preference is food factor (taste, nutrition content, food processing). Local food potential in order to reach food diversification consider to food preference and production. It also an alternative way to fulfill carbohidrat, animal and plant based protein, vitamin and mineral needs. Output of Chi square dan Spearman analysis show that almost food don’t have correlation (p>0.05) with individual and environmental characteristic. Potensial local food based on food preference and production as alternative food for food diversification i.e. corn, cassava, sweet potato, taro (carbohydrate sources): fish, mung bean, tempe, tofu (protein sources); and green leaf vegetables, cow peas, banana and guava (vitamins and minerals sources). Production data shows that corn, fish, mung bean, and soybean production need to be increased its production or import from the other region, especially in West Java. This analysis need to support food preference and by itself it will also support food diversification.

Abstrak: Food preference has an important role in defining children’s food pattern. Food preference that is formed earlier will persist to influence food preference in adult. In the other words, children’s food preference is a critical point in defining adult’s food preference. Thus, study about children’s food preference and many factors that were related is important to do. The general objective of this study was to identified factors that is correlate to food preference of school children in bogor city, and the specific objectivess were to: 1). Identified individual characteristic of subject, 2). Identified Family’s socio economics condition of subject, 3). Identified school children’s food preference, and 4). Analyze correlation between food preference and many factors. This study used cross-sectional design and the subject was 90 students from 3 elementary school in Bogor City. The correlation between factors and food preferences analized use inferensia statistics which are: Chi Square and Rank Spearman. Food preference of school children shows that school children tend to like certain kind of food in each food groups. There are several kinds of food in each foods group which is less like by school children. Fruits are liked by most school children. Most of school children like a kind of food because of the organoleptic characteristic of food, especially taste. Individual characteristics and family’s socio economic conditions explained little of the variation in school children’s food preference. The statistic test shows that preference of certain food has correlation with individual and family’s socio economic conditions. School children’s food preference doesn’t not show variety yet. Interventions are needed to direct school children’s food preference become more various.

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.
