Judul: Hubungan Perilaku Gizi Ibu dengan Kecukupan Energi, Protein dan Zat Gizi Mikro Keluarga pada Pemukiman Kumuh Di Jakarta Selatan
Abstrak: Determinant and regulator of family eating habit is a mother. Therefore, knowledge, attitudes, and practices of maternal nutrition essentially to be considered and improved. The purpose of this study was to determine the relationship between maternal nutritional behaviour with famili’s nutrient adequacy in slums at South Jakarta. The samples in this study were family and mother as the unit of analysis. The research was conducted by interviewing the unit of analysis. Mothers in this study has good knowledge and attitudes of nutrition, but their practises of nutrition was moderate. Over all, energy adequacy of family was still deficit, but protein adequacy was enough. Adequacy of vitamin A, vitamin B, and phospor were adequate, but calcium, iron, and vitamin C were deficit. Stepwise regression results indicate that maternal nutrition knowledge, attitude, and practice does not affect the nutritional adequacy of family who lived in slum at South Jakarta.

Judul: Hubungan Karakteristik Keluarga, Pengetahuan dan Sikap Gizi, serta Perilaku Hidup Bersih dan Sehat dengan Status Gizi Ibu Di daerah Kumuh, Jakarta Selatan.
Abstrak: Tujuan penelitian ini adalah menganalisis hubungan karakteristik keluarga, pengetahuan gizi, sikap gizi serta perilaku hidup bersih dan sehat(PHBS) terhadap status gizi ibu. Penelitian ini menggunakan data sekunder. Subjek dalam penelitian ini adalah ibu dengan kriteria tidak hamil. Hasil penelitian menunjukkan terdapat hubungan yang signifikan (p<0.05) antara pengetahuan gizi dengan sikap gizi. Terdapat hubungan signifikan (p<0.05) antara sikap ibu dengan tingkat kecukupan protein dan energi. Tidak terdapat hubungan signifikan (p > 0.05) antara perilaku hidup bersih dan sehat dengan tingkat kecukupan protein dan energi. Tidak terdapat hubungan antara Perilaku Hidup Bersih dan Sehat dengan status gizi ibu.Terdapat hubungan positif yang signifikan antara usia dengan status gizi ibu. Tidak terdapat hubungan positif antara variabel lain dengan status gizi. Terdapat dua kelompok berbeda berdasarkan hasil uji Klaster analisis, yaitu kelompok masyarakat sungai dan masyarakat rel kereta api.

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.
