Judul: Budaya Makan Pokok Beras Singkong dan Hubungannya dengan Pola Konsumsi dan Tingkat Kecukupan Gizi serta Status Gizi Masyarakat desa Cireundeu Cimahi Jawa Barat
Abstrak: Penelitian ini bertujuan untuk mempelajari budaya makan nasi yang berasal dari singkong analog” sebagai makanan pokok dan kaitannya dengan pola konsumsi dan tingkat konsumsinya kecukupan gizi serta status gizi desa Cireundeu masyarakat, Cimahi, Jawa Barat. Metode yang diterapkan dalam penelitian ini Kualitatif dan Kuantitatif. Metode kualitatif menggunakan wawancara mendalam dengan terstruktur Kuesioner dilakukan kepada tokoh masyarakat dan pejabat pemerintah, sedangkan Metode kuantitatif dengan desain cross sectional diterapkan pada 19 keluarga yang mempunyai kebiasaan makan “beras analog” yang berasal dari singkong. Komunitas itu siapa dikonsumsi sebagai makanan pokok yang mengikuti kepercayaan “Sunda Wiwitan”. Itu Pola masyarakat keluarga yang mengkonsumsi nasi turunan singkong adalah sebagai mengikuti banyak kemudian makan dua kali sehari (63,16%) dan mempunyai kebiasaan makan bersama. Status gizi penduduk muda dan dewasa sebagian besar normal. Namun, untuk anak balita hanya 50% yang normal dan 50% stunting. Tidak ada anggota keluarga yang berstatus kelebihan berat badan. Diantara tingkat kecukupan gizi, energi yang masuk lebih banyak hanya 89%. Namun, proteinnya dan lemak di mana sekitar 100%.

Judul: Sikap dan Perilaku Konsumsi Masyarakat terhadap Beras Padi (Oryza sativa) dan Beras Singkong (Manihot esculenta) sebagai Bahan Pangan Pokok (Kasus Masyarakat Kampung Cireundeu, Kelurahan Leuwigajah, Kecamatan Cimahi Selatan, Kota Cimahi, Provinsi Jawa Barat
Abstrak: Indonesia has a high proportion of household, which have deficit food energy in every provinces, that is why diversification is needed, even become one of the main pillars in achieving the food security. However, in fact, Indonesian people are still depended on the rice paddy. Changing people's behavior in consuming the rice paddy is not easy, it is needed to learn first about how people's attitudes towards staple’s food of the rice paddy and the non rice paddy. That is because the attitudes can influence behavior. This study investigated the attitude and consumption behavior of Cireundeu Village community between the rice paddy and rice cassava. Some people of Cireundeu village have been consumed rice cassava as their staple food. Based on those case, people’s attitudes and consumption behavior can be interesting to be used as the implementation learning of food security or food diversification in other areas. The method used in this study are quantitative and supported by qualitative data. Quantitative data collected by interviewing peoples with questionnaires. The results of this study indicated that the group of respondents that consume rice paddy tended to have a positive attitude towards the rice paddy and a neutral attitude towards rice cassava. While the group of respondents who consume rice cassava and the group of respondents who consume both staple food have a tendency to a neutral attitude to both. However, attitudes toward food staples did not correlate consumption behavior, that’s meaning attitude did not determine the consumption behavior.

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.
