Abstrak: Home care is a service system which is used to overcome problems arising from the increasing number of elderly population, such as malnutrition. The purpose of this study was to identify food consumption, health status, depression level and nutritional status of elderly participants and non participants Home Care, as well as to analyze the relationship. A cross sectional study was conducted on elderly people aged 60 years and above in Tegal Alur, West Jakarta. A total of 60 elderly (30 participant and 30 non participants) were actively followed as participants. They were interviewed on demography and social economic status, one-month semi-quantitative food frequency questionnaire, health status, geriatric depression scale (GDS) short version, and assessed by anthropometric measures. Average level of adequacy energy, protein, calcium, phosphorus dan vitamin C of participant relatively lower than non participants (87,5% vs 95,5%; 80% vs 90%; 51,4% vs 59,2%; 104% vs 116,1% and 73,1% vs74,9%, respectively). The study showed that no significant difference in term food consumption, health status, depression level, and nutritional status between the elderly participant vs non participants. And as much as 63,3 % participant and 53,3% non participants experienced more than one type of health complaince and most of them are well nourished and not depressed. The statistical analysis with correlation test showed that health status of elderly significantly positive with the level of depression. While other variables such as duration of illness significantly negative with level of adequacy of energy, protein, minerals, and nutritional status. Percent RDA of energy, protein and minerals are positively associated with nutritional status.

Abstrak: Decreases of physiological function in the body will occur in the elderly population. As a result, the elderly body’s ability to work normally is decreased, especially in term of consuming foods. The lack of food consumption in the elderly will affect their nutritional status and increase the risks of the occurrence of anemia and health status problems. The objective of this study was to know the relationships of food consumption, nutritional status, and health status of the elderly living in nursing homes and families at the City of Bandung. A retrospective study of 115 elderly people was conducted and data collected on May 2012. The study showed that level of energy intake was normal, protein was lack, calcium was lack, iron was adequate, and vitamins were lack. Correlation test showed that there was no correlation among level of energy, protein, calcium, iron, vitamin B1, B2, B6 and vitamin C intake to health status (p>0.05). However, there was correlation among level of protein intake to nutritional status, level of vitamin B1 and B2 intake to health status, nutritional status and anemia to health status, as well as blood pressure to anemia (p<0.05).

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.
