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: Analisis Aktivitas Fisik, Konsumsi Sayur, Buah Dan Kopi, Serta Sindrom Metabolik Karyawan Di Pt Indocement Citeureup
Abstrak: Penelitian ini dilakukan untuk menganalisis aktivitas fisik, konsumsi sayur, buah dan kopi, tekanan darah, profil lipid, sindrom metabolik dan status gizi karyawan middle age non-obese di PT Indocement Citeureup. Desain cross sectional dengan purposive sampling 59 orang karyawan middle age non-obese di PT Indocement digunakan pada studi ini. Hasil penelitian menunjukkan sebanyak 34% contoh memiliki status gizi lebih dan 88% contoh memiliki persen lemak yang tinggi. Sebanyak 17% contoh mengalami hipertensi dan 80% contoh mengalami dislipidemia. Sebanyak 49% contoh termasuk ke dalam kategori aktivitas fisik ringan. Sebanyak 20% contoh mengalami kejadian sindrom metabolik. Hasil penelitian menunjukkan bahwa rata-rata konsumsi sayur contoh adalah 61.5±44.8 gram yang masih rendah dibandingkan dengan anjuran dari PGS, rata-rata konsumsi buah contoh adalah 159.5±104.7 gram yang sudah sesuai dengan anjuran dari PGS dan rata-rata konsumsi kopi contoh adalah 250.1±259.8 ml yang masih termasuk dalam konsumsi wajar. Terdapat hubungan negatif yang signifikan antara konsumsi sayur dengan lingkar perut (p<0.05). Tidak ada hubungan yang signifikan antara aktivitas fisik, konsumsi sayur, buah dan kopi dengan kejadian sindrom metabolik (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.
