Judul: Correlation between Ampo Consumption Habit with Consumption and Nutritional Status of People of Bektiharjo Village, Tuban
Abstrak: Ampo merupakan camilan berbahan baku tanah liat yang berasal dari Kabupaten Tuban. Ampo tergolong pangan yang unik berbahan baku tanah liat dan dikonsumsi manusia (geofagi) dalam kondisi nondarurat dan nonpatologis. Ampo juga dipercaya masyarakat Tuban dapat menguatkan sistem pencernaan dan memiliki berbagai manfaat lainnya. Tujuan khusus penelitian ini adalah untuk menganalisis karakteristik sosial–ekonomi,konsumsi gizi, tingkat kecukupan gizi, hubungan kebiasaan mengonsumsi Ampo dengan tingkat kecukupan gizi dan status gizi masyarakat, dan hubungan tingkat kecukupan gizi dengan status gizi di Desa Bektiharjo, Kecamatan Semanding, Kabupaten Tuban, Provinsi Jawa Timur. Sampel dalam penelitian ini sebanyak 35 diwawancarai untuk mengetahui karakteristik, recall dalam 2 x 24 jam, dan kebiasaan makan Ampo. Sebagian besar sampel (97.1%) adalah perempuan yang mulai mengonsumsi Ampo sejak berusia 3 tahun atau saat hamil. Hasil analisis Spearman menunjukkan terdapat hubungan negatif antara kebiasaan makan Ampo berdasarkan jumlah Ampo yang dikonsumsi dengan tingkat kecukupan lemak (r=-0.416) dan tingkat kecukupan zat besi (r=-0.436) (p<0.01). Hasil analisis ini juga menunjukkan tidak terdapat hubungan antara frekuensi dan jumlah konsumsi Ampo dengan status gizi sampel. Hasil analisis Pearson menunjukkan adanya hubungan positif yang signifikan antara tingkat kecukupan zat gizi yaitu karbohidrat (r=0.500; p<0.01), protein (r=0.357), kalsium (r=0.408), dan fosfor (r=0.351) (p<0.05) dengan status gizi sampel.

Judul: Keragaman Konsumsi Pangan dan Hubungannya dengan Status Gizi pada Orang Dewasa di Perkotaan
Abstrak: This study aimed to analyze the diversity of food consumption and the association with nutritional status among adults in urban area especially in DKI Jakarta. This study using a cross sectional design and secondary data. Subject were 102 adults. The data collected were socio economic characteristic (age, education, family size, nutritional status (BMI and waist hip ratio), food consumption (nutrition intake and dietary diversity score) and healthy status. Diversity of food consumption can measured by Dietary Diversity Score methods and the results showed that most of subject has a good food diversity. Spearman correlation test showed that there was a positive relationship (p<0.05) between BMI with healthy status and education with iron consumption. Other variables observed were not significantly related (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.
