Judul: Status Gizi, Konsumsi Pangan, dan Persepsi terhadap Kesehatan Reproduksi pada Remaja Putri SMU dan SMK di Kota Bogor dikaitkan dengan Kesiapan Reproduksi
Abstrak: Kualitas reproduksi akan terwujud bila didukung kesiapan reproduksi yang baik. Kesiapan reproduksi pada remaja dipengaruhi kesiapan fisik yang digambarkan melalui status gizi dan kesehatan remaja serta kesiapan mental berupa persepsi remaja terhadap kesehatan reproduksi. Status gizi salah satunya dipengaruhi oleh konsumsi pangan seperti kebiasaan makan dan diet, konsumsi fast food serta kebiasaan merokok. Disamping itu, persepsi terhadap kesehatan reproduksi yang baik akan sangat mendukung kesiapan reproduksi remaja guna menurunkan angka kematian ibu dan kejadian berat bayi lahir rendah. Dalam penelitian ini dipelajari status gizi, perilaku konsumsi, dan persepsi remaja putri SMU dan SMK di dikaitkan dengan kesiapan reproduksi. Penelitian dilakukan pada dua SMU (SMUN 1 dan SMUN 3) dan dua SMK (SMKN 1 dan SMKN 3) di Kota Bogor. Analisis statistik yang digunakan adalah uji korelasi Spearman's, uji beda t (t-test) digunakan untuk mengetahui ada tidaknya perbedaan setiap variabel di SMU dan SMK, dan analisis regresi berganda.

Judul: Kebiasaan Makan dan Pengetahuan Kesehatan Reproduksi Remaja Putri Peserta Pusat Informasi dan Konseling Kesehatan Reproduksi Remaja (PIK-KRR)
Abstrak: ~ aim of this research was to observe food habit and knowledge of reproduction ftet{lth of female adolescence as participant and non partiscipant of Information cintre and Counseling of Adolescence Reproduction Health (PIK-KRR) at SMU 1 ;tiwa and SMK 1 Liwa. The specific objectives of this research were: 1) to study tIi socio-economy and demography of their family, 2) to observe their food habit, 3~to study their knowledge of nutrition 4) to study their knowledge reproduction hee.lth, 5) to analyze the relationship betwen socio~economy, food habit, k~wledge of nutrition and reproduction health. Reproduction readiness in a~lescence is influenced by physical readiness which is reflected from nutrition ail health status and mental readiness in the form of adolescence perception ai.:..>. ut reproduction health. This research used cross sectional design. The site of t~ research is determined using purposive sampling. The SMU 1 Liwa was cijbosen because this school has PIK-KRR and most of the graduates continue t'iir study to the higher level of education, and SMKN Liwa Lampung Barat was cioosen because this school does not have PIK-KRR yet and most of the gffiduates do not continue their study. Spearman's Correlation and t-test utilized t~know whether there were any difference in each variable in SMU and SMK s&.., dents. The results of the study show that, SMU female adolescence have better reproduction readiness than SMK female adolescence. There fore it is important for female adolescence to get correct information about nutrition, and reproduction health through formal or informal way.

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.
