Judul: Analisis Penyelenggaraan, Kontribusi, Tingkat Kesukaan dan Daya Terima PMT-AS di SDN 1 Malangsari, Cipanas, Lebak, Banten
Abstrak: Objective of this research is to analyze the PMT-AS organization, contribution, level of preferences and food acceptability at Malangsari 1 elementary school. The study was located in Cipanas, Lebak, Banten. Study design used a cross sectional study. Number of subjects taken as many as 68 students in grade 5 and 6 in SDN 1 Malangsari, Cipanas Lebak, Banten. The results of this study is the organization of snack PMT-AS was very good. PMT-AS contributed to the adequacy of energy (11%) and protein (8.6%). The highest of acceptability level (97.1%) and the degree of preferences (98.5%) was aremarem snack. Spearman correlation test showed that there is a significant relationship between consumption at each level of each PMT-AS snack, exept on combro ayam snack. Independent T-test showed that had different between male and female students at nagasari ayam and bakwan sayur snack (p<0.05). Degree of preferences at female student higher than male student at nagasari ayam snack. Degree of preferences at male student higher than female student at bakwan sayur snack. Chi-square test showed that there is not relationship between nutritional status with the level of preferences and the degree of acceptability of PMT-AS (p >0.05).

Abstrak: The general objective of this study were to assess food service management, food acceptance, and the consumption’s level of students boarding school dormitory SMA 1 Pemali Bangka Belitung. The research was conducted in May-July 2013 with a cross sectional design. Subjects was purposively chosen with the total of 71 students. A total of51.0% criticalcomponent of food service management the have implemented which consists ofplanning, purchasing, storing, processing, servicing,personal hygiene, andsanitation.Spearman correlation analysis showed that the preference level for taste of food was significantly associated (p<0.05)withenergy and protein sufficiency level. The preference level for temperature of food was significantly associated(p<0.05) with sufficiency levels of phosphorus. Preference level for temperature of food was significantly associated (p<0.05)with compliance level of energy and iron. The level of compliance was significantly associated (p<0.05)with sufficiency level of energy, iron, phosphorus, and zinc. Energy, protein, fosfor, iron intake from dormitory was significantly negatively associated(p<0.05) with intake from non dormitory.

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.
