Judul: Gaya hidup dan kejadian sindrom metabolik pada karyawan laki-laki berstatus gizi obesitas di PT. Indocement Citeureup
Abstrak: The objectives of this study were to analyze life style and incidence of metabolic syndrome among obese male employees in PT. Indocement Citeureup. The cross sectional design was applied in this study, with purposive sampling involving 59 male obese employees selected by inclusion criteria. As much 49.15% sample has metabolic syndrome with the highest prevalence of metabolic syndrome marker was central obesity (96.55%), followed by hipertriglyceridemia (82.76%), low level of High Density Lipoprotein (HDL) (72.41%), high level of fasting blood glucose (62.07%) and hypertension (55.17%). There is no significant difference in proportion of metabolic syndrome incidence according to age, history of obesity, smoking habits, excercise habits, physical activity level and eating behavior (p>0.05). High consumption of cigarettes significantly correlated (p<0.05) with lower diastolic blood pressure and greater abdominal circumference. Unhealthy eating behavior also significantly correlated with lower level of HDL cholesterol, while snacking behavior correlated with high level of fasting blood glucose (p<0.05).

Judul: Gaya Hidup, Intake Zat Gizi Dan Morbiditas Orang Dewasa Yang Berstatus Gizi Obes Dan Normal
Abstrak: The objective of this research was to identify characteristic of samples, food intake, lifestyle, morbidity and energy balance among adult obese and normal nutritional status. A cross-sectional study was conducted from October to November 2010 in Bogor Agricultural University (BAU). The study participants were employee’s rector of BAU. The samples were chosen purposively with criteria were adult category, age >21 years, male and female gender, body mass index (BMI) >27.0 for obese nutritional status; BMI 18.5-25.0 for normal nutritional status, and ready for being sample of research. The number of obese sample were 25 and normal sample 25 people. Majority (72%) of obese samples were 30-49 years old. There was a significant difference in education levels of among samples (p<0.05). Rice, cassava, street food and soft drink consumption were found higher in obese than normal samples. Statistical analysis showed that there was a significant difference in obese and normal samples in protein intakes and adequacy level of protein (p<0.05). There was a significant difference in leisure-time between obese and normal samples (p<0.05). Ready-to-eat food habit was found higher in obese than normal status. The average of energy balance among samples were negative. In addition, there was a significant difference in family history of obesity between obese and normal samples (p<0.05). For the last three month, both subjects suffer from infections of acute respiratory. Diabetes mellitus and uric acid was found in obese subjects, while anemia was found in normal subjects The study showed that nutritional status was positively correlated with age, education levels, frequency of cassava consumption, family history of obesity and ready-to-eat food habit and negatively associated with intakes of protein.

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.
