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: Faktor-faktor yang Berhubungan dengan Anemia pada Ibu Hamil di Kecamatan Gegesik Kabupaten Cirebon
Abstrak: Salah satu masalah gizi di Indonesia adalah anemia pada ibu hamil yang merupakan penyebab tingginya angka kematian dan berat bayi lahir rendah. Tujuan penelitian ini adalah menganalisis faktor-faktor yang berhubungan dengan anemia pada ibu hamil di Kecamatan Gegesik. Desain penelitian yang digunakan adalah potong lintang. Penelitian ini menggunakan data sekunder yang melibatkan total subjek sebanyak 99 ibu hamil, yakni 51 ibu hamil anemia dan 48 ibu hamil non anemia. Tingkat kecukupan energi, protein, dan zat besi semua subjek umumnya berada pada kategori defisit. Frekuensi konsumsi pangan enhancher zat besi lebih tinggi pada ibu hamil normal, sedangkan frekuensi konsumsi inhibitor zat besi lebih tinggi pada ibu hamil anemia. Sebagian besar ibu hamil memiliki jarak kehamilan dan paritas tidak beresiko. Status gizi kurang lebih tinggi pada kelompok ibu hamil anemia. Hasil uji bivariat dengan menggunakan Spearman menunjukan bahwa terdapat hubungan yang signifikan negatif antara usia kehamilan dan frekuensi konsumsi kopi dengan kadar Hb. Selain itu, terdapat hubungan signifikan positif antara frekuensi konsumsi daging sapi/kambing dengan kadar Hb ibu hamil. Hasil analisis multivariat menunjukkan ibu hamil yang mengonsumsi daging sapi/kambing <1 kali/bulan memiliki risiko 2,79 kali mengalami anemia dan ibu hamil yang mengonsumsi daging ayam <3 kali/minggu memiliki risiko 2,39 kali mengalami anemia., One of the nutritional problems in Indonesia is anemia in pregnant women which is a high maternal mortality rate. This study aims to analyze the factors associated with anemia in pregnant women at Gegesik Cirebon Regency. The research design with cross-sectional study. This study used secondary data with subjects of 99 pregnant women, consist of 51 anemic pregnant women and 48 non-anemic pregnant women. The level of energy, protein, and iron sufficiency is generally in defisit category. The frequency consumption of iron enhancher is higher in non-anemic pregnant women, while the frequency consumption of inhibitor iron is higher in anemic pregnant women. Most of pregnant women have pregnancy intervals and parity is not at risk. Underweight nutritional status is higher in the group of anemic pregnant women. The results of bivariate test using Spearman showed that there was a significant negative relationship betweet gestational age and frequency of coffee consumption with Hb levels. There is a significant positive relationship between the frequency of consumption meet/lamb with Hb levels of pregnant women. The results of multivariate analysis showed This study showed meat/lamb consumption less than one times per month associated with increased of the risk of anemic by 2,79 times and chicken consumption less than third time per weeks associated with anemic by 2,39 times compared with pregnant women with third time per weeks.

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.
