Judul: Studi keberhasilan kegiatan penimbangan balita di desa tamansari, kecamatan ciomas, kabupaten bogor propinsi jawa barat
Abstrak: Banyak faktor yang mempengaruhi keberhasilan kegiatan penimbangan balita, yaitu partisipasi ibu balita (dipengaruhi oleh latar belakangnya), kader pelaksana penimbangan, pemuka masyarakat dan sarana dalam kelompok penimbangan. Pada penelitian ini khususnya akan dilihat dari segi ibu peserta dan kader dalam kelompok penimbangan. Berpijak dari hal di atas, maka tujuan penelitian ini adalah untuk mengetahui perbedaan latar belakang kader dan -ibu peserta di Posyandu yang berhasil dan kurang berhasil di Desa Tamansari. Pengambilan contoh dilakukan secara acak sederhana terhadap ibu peserta penimbangan masing-masing 30 orang di- Posyandu yang berhasil dan kurang berhasil, sedangkan semua kader gizi diambil sebagai contoh. Dengan demikian jumlah contoh seluruhnya adalah 60 orang ibu peserta dan 24 orang kader gizi. Data latar belakang (tingkat pendidikan, umur, jumlah anak, besar keluarga dan pendapatan keluarga), pengetahuan dan sikap kader gizi dan ibu peserta dilakukan dengan cara Wawancara sedangkan data ketrampilan dilakukan dengan peng- Data sekunder meliputi data SKDN, sarana dan pelaksanaan kegiatan penimbangan. Dalam penelitian ini ada dua Posyandu. Posyandu yang dikategorikan berhasil mempunyai tingkat pencapaian program (N/S) sebesar 27.7 persen, tingkat partisipasi program (D/S) 53.5 persen, tingkat liputan program (K/S) sebesar 91.1 per- rasio kader balita sebesar 20 anak balita setiap kader. 11.6 persen, D/S 21.8 persen, K/S 64.6 persen dan rasio kader balita sebesar 45 anak balita setiap kader. Hasil penelitian menunjukkan bahwa pendapatan dan jum- lah anggota keluarga kader gizi antara Posyandu yang berha- sil dan yang tidak berhasil berbeda nyata. Sedangkan pen- didikan, umur kader, jumlah anak, pengetahuan, sikap dan ketrampilan kader gizi tidak menunjukkan perbedaan yang r nyata antara kedua Posyandu. Pendidikan, besar keluarga dan sikap ibu peserta pada Posyandu yang berhasil berbeda nyata dengan Posyandu yang kurang berhasil. Sedangkan umur, pendapatan, jumlah anak, pengetahuan dan ketrampilan ibu peserta pada kedua Posyandu tidak menunjukkan perbedaan yang nyata…dst

Judul: Hubungan Partisipasi Ibu Balita di Posyandu dengan Pengetahuan, Sikap, dan Perilaku Gizi Ibu Balita serta Status Gizi Balita di Kecamatan Tamansari, Kabupaten Bogor
Abstrak: The objective of this research is to examine correlation between mother’s participation in posyandu with knowledge, attitude, behavior and adequacy level of children under-five nutrition in Tamansari, Bogor. This research is part of the research which its title was “a Multi-Approach Intervention to Empower Posyandu Nutrition Program to Combat Malnutrition Problem in Rural Areas” was conducted on February 2012 by using a cross sectional study design. 120 people become sample in this research were selected purposively with sample criteria are (1)have children under-five (male or female 0-60 month), (2)registered as a users of posyandu, (3)ready to be interviewed. The data which used are primary data including characteristic of family and individu sample (big of families, income of families, age, education, and job of sample, characteristic of children underfive (gender and age), mother’s participation in posyandu, knowledge, attitude, behavior of nutrition, food consumption of children under-five, and nutritional status of children under-five. Secondary data including general image of research location. The analysis was carried out with Structural Equation Modeling (SEM). Based on the analysis of SEM, mother’s participation has a significant effect on the level of nutrition knowledge (T-value =-2.59E16). Nutrition knowledge has a significant effect with nutrition attitude (T-value = -3.8323). Nutrition attitude has a significant effect with nutrition behavior (T-value = -3.8323). Nutrition knowledge has a significant effect with nutrition behavior (Tvalue = -3.8323). Nutrition attitude has a significant effect with nutritional status of children (T-value = -3.8323). Nutrition behavior has a significant effect with nutritional status of children (T-value = -5.1027)

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.
