Judul: Factors Associated with Hemoglobin Levels in Adolescent Girls
Abstrak: Salah satu masalah gizi yang umum terjadi pada remaja putri di Indonesia adalah anemia. Kadar hemoglobin bisa berbeda-beda setiap individu karena dipengaruhi oleh berbagai macam faktor. Tujuan dari penelitian adalah menganalisis faktor-faktor yang berhubungan dengan kadar hemoglobin pada remaja putri. Penelitian ini menggunakan desain cross sectional study serta melibatkan 102 subjek yang merupakan siswi SMPN 2 Bojonggede. Data yang digunakan adalah data sekunder dari kegiatan skrining anemia pada remaja putri di desa Ragajaya tahun 2023. Subjek penelitian paling banyak adalah perempuan berusia 14 tahun (36%). Sebagian besar status gizi subjek termasuk ke dalam kategori normal (56%). Sebanyak 54% subjek memiliki frekuensi konsumsi pangan hewani tidak sering (1-3 kali/minggu). Hampir seluruh subjek penelitian tidak patuh dalam mengonsumsi TTD (95%). Rata-rata nilai hemoglobin subjek adalah 11,83, One of the nutritional problems that commonly occurs in adolescent girls in Indonesia is anemia. Hemoglobin levels can vary for each individual because they are influenced by various factors. The aim of the research is to analyze factors related to hemoglobin levels in adolescent girls. This research used a cross sectional study design and involved 102 subjects who were female students at SMPN 2 Bojonggede. The data used is secondary data from anemia screening activities for adolescent girls in Ragajaya village in 2023. Most research subjects were 14 year old girls (36%). Most of the subjects

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.
