Judul: Analisis Konsumsi Buah Dan Sayur Di Provinsi Dki Jakarta Berdasarkan Data Riset Kesehatan Dasar (Riskesdas) 2010
Abstrak: Penelitian ini bertujuan untuk menganalisis konsumsi buah dan sayur di Provinsi DKI Jakarta dengan menggunakan data sekunder hasil Riskesdas tahun 2010. Desain penelitian yang digunakan adalah cross sectional study dengan jumlah sampel sebanyak 3.120 orang terdiri dari 1.567 laki-laki dan 1.553 perempuan. Hasil penelitian menunjukkan pada kelompok usia pra sekolah rata-rata konsumsi buah sebesar 36.3 g/hari dan konsumsi sayur 40.8 g/hari. Pada kelompok usia sekolah rata-rata konsumsi buah terdiri dari 30.8 g/hari dan sayur 29.6 g/hari, sedangkan pada usia pra remaja dan remaja rata-rata konsumsi buah sebesar 33.2 g/hari dan 29.9 g/hari, dan rata-rata konsumsi sayur 33.6 g/hari dan 37.2 g/hari. Pada kelompok usia dewasa rata-rata konsumsi buah dan sayur 36.9 g/hari dan 50.2 g/hari. Hasil uji korelasi Spearman menunjukkan adanya hubungan signifikan (p<0.05) antara pengeluaran rumahtangga, besar anggota rumahtangga, dan umur dengan konsumsi buah dan sayur. Hasil uji Chi Square menunjukan terdapat hubungan yang signifikan (p<0.05) antara jenis kelamin dengan konsumsi buah dan sayur, dimana pria mengkonsumsi lebih besar dari wanita.

Judul: Analisis KonsumsiPanganPendudukProvinsi DKIJakarta
Abstrak: This study was aimed to assess food consumption of people in DKI Jakarta. The design of this study was cross sectional study. The study which is conduted from analyzing food consumption data of Basic Health Research 2010 collected by a 24-hour recall method. Subject obtained from1626 households with 4964 household members.The result showed that energy consumption average of households stood at 1500 ± 711.48 kkal/cap/day and protein consumption average of households stoodat 50.82 ± 27.1 g/cap/day.Almost all (53.1%) energyadequacy level (TKE) households stood atextreemly leveldeficit category,proteinadequacylevel (TKP) households stood at normal category (47.2%) and desirable dietary pattern (PPH) stood at76.6. Spearman test resultshowed there wasno significant correlation(P>0.05) between maternal education level, number of household memberand food expenditure to householdsTKE and TKP.

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.
