Judul: Kualitas Konsumsi Pangan Anak Jalanan Jakarta.
Abstrak: Penelitian ini bertujuan menganalisis kualitas konsumsi pangan pada anak jalanan di Jakarta. Desain yang digunakan adalah cross sectional study melibatkan 33 anak jalanan dengan rentang umur 10-18 tahun. Penelitian dilakukan pada Mei - Juli 2016. Data yang diambil antara lain karakteristik keluarga dan anak jalanan, aktivitas, pengetahuan gizi, dan konsumsi pangan anak jalanan. Sebanyak 54.55% subjek berjenis kelamin perempuan. Sebagian besar (66.67%) subjek memiliki status gizi normal. Sebanyak 84.84% contoh bekerja selama 5-7 hari dalam seminggu. Sebanyak 51.52% subjek memiliki pengetahuan gizi yang baik. Sebagian besar subjek (75.75%) memiliki kualitas konsumsi pangan yang buruk. Hasil uji korelasi Spearman menunjukkan terdapat hubungan signifikan (p < 0.05) antara durasi di jalan dengan pendapatan per hari. Tidak terdapat hubungan antara durasi di jalan dan pengetahuan gizi dengan tingkat kecukupan zat gizi, pengetahuan gizi dengan kualitas konsumsi pangan, kecukupan zat gizi dengan status gizi, dan kualitas konsumsi pangan dengan status gizi.

Judul: Pola Aktivitas, Konsumsi Pangan, Status Gizi  Dan Kesehatan Anak Jalanan Di Kota Bandung
Abstrak: The general objective of this research was to know and analyze the correlation of pattern activity, food consumption, nutritional status and health of street children. The research design was cross sectional study. This research was part of project research Socio-economics and Environmental Factors Contributing to The Health and Nutritional Status of Street Children. Data was collected on February 2009 in Bandung, West Java. Street children was chosen by purposive sampling from eight NGOs in Bandung. Street children criteria were: 1) 5-18 years old 2) boys and girls 3) spend time in the street at least four hours in a day 4) work for a living in the street, commonly work as singers, beggars, shoe-polisher, porters etc. The result showed that most street children activity was singers, spend 4-8 hours in a day and 4-6 days in a week. The average energy and protein adequacy level of street children was light deficit category, iron and vitamin C in low category and vitamin A in sufficient category. Almost street children have normal nutritional and health status and good personal hygiene. There is no correlation between activity and duration of street children with nutrition adequacy level. There is no correlation between personal hygiene and nutritional status with health status.

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.
