Judul: The Correlation of Food Consumption and Iron Supplementation and Food Taboo with Hemoglobin Concentration of Pregnant Women at RSKIA Kota Bandung
Abstrak: Anemia pada ibu hamil dapat meningkatkan resiko kematian pada ibu hamil serta pertumbuhan dan perkembangan janin tidak optimal. Penelitian bertujuan untuk menganalisis hubungan antara konsumsi pangan dan tablet tambah darah (TTD) serta food taboo dengan kadar hemoglobin (Hb) ibu hamil. Desain penelitian adalah cross sectional yang melibatkan 41 contoh dan dilakukan pada bulan Oktober sampai November 2019 di RSKIA Kota Bandung. Data konsumsi pangan diperoleh dengan food recall 1x24 jam dan FFQ. Data food taboo dan konsumsi TTD dikumpulkan dengan wawancara. Data kadar Hb diperoleh dari buku Kesehatan Ibu dan Anak (KIA). Hasil uji korelasi menunjukkan tidak terdapat hubungan yang signifikan antara food taboo dengan tingkat kecukupan energi dan zat gizi (protein, lemak, karbohidrat, vitamin C, folat, dan zat besi) (p>0.05). Tingkat kecukupan zat besi (p=0.046, r=-0.314) dan asam folat (p=0.013, r=-0.384) berhubungan signifikan negatif dengan kadar Hb. Tidak terdapat hubungan yang signifikan antara konsumsi TTD dengan kadar Hb, namun konsumsi TTD kelompok non anemia (103.7±32.7 tablet) adalah lebih banyak daripada kelompok anemia (87.8±49.3 tablet). Hal ini mengindikasikan bahwa konsumsi TTD yang lebih banyak, kadar Hb contoh lebih tinggi (tidak anemia)., Anemia in pregnancy could increase the risk of maternal death and adverse effect on pregnancy outcomes. The study aimed to analyze the correlation between food consumption, iron supplementation and food taboo with hemoglobin concentration of pregnant women. This cross-sectional study was conducted on 41 pregnant women at RSKIA Kota Bandung from October until November 2019. Food consumption data was collected by food recall 1x24 hours and FFQ. Food taboo and the consumption of iron supplement collected by questionnaire. Hemoglobin concentration was obtained from the subjects’ KIA book. This study showed that food taboo had no significant correlation with the adequacy level of energy and nutrients (protein, fat, carbohydrate, vitamin C, folate, and iron) (p>0.05). There was a negative correlation between the adequacy level of iron (p=0.046, r=-0.314) and folate (p=0.013, r=-0.384) with subjects’ hemoglobin concentration. The consumption of iron supplement and hemoglobin concentration was found not correlated. But, the consumption of iron supplement of non-anemic subjects was higher (103.7±32.7 tablets) than anemic subjects (87.8±49.3 tablets). This indicated that the higher consumption of iron supplement, the better subjects’ hemoglobin concentration.

Judul: Hubungan Tingkat Kecukupan Protein dan Zat Besi (Fe) dengan Kadar Hemoglobin Ibu Hamil di Kota Bogor
Abstrak: Levels of hemoglobin is one of the most common indicator used to determine the status of iron deficiency anemia, which is closely related by intake of protein and iron that increased and must be adequate during pregnancy. The aim of study was to explain relationship between %RDA of protein and iron with levels of hemoglobin at pregnant mother in Bogor City. The design of this study was cross-sectional study, and the number of samples were 45 pregnant women. The result of the research show that the anemia prevalence was 22.2%. Consumption of animal foods as a source of iron was still low (60.3 g) it might for 68.8% of the samples had inadequate iron. Intake of vitamin C as a enhancer of iron bioavailability was 27.0 mg. This study has shown that intake of heme iron (6.9 mg) was lower than the non-heme iron (10.4 mg). Most of sample on group anemia and non anemia has %RDA of energy and protein as a deficit level of heavy and then %RDA of vitamin A, vitamin C, folic acid, and iron as a deficit. Results test correlation show there is no relation between %RDA of protein and iron with levels of hemoglobin (p>0.05)

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.
