Judul: Factors Related to the Coverage of Iron Supplementation for Pregnant Woman in Indonesia
Abstrak: Cakupan pemberian TTD kepada ibu hamil merupakan salah satu indikator keberhasilan pelaksanaan program pemberian TTD kepada ibu hamil. Pelaksanaan program tersebut memerlukan sumber daya dan perilaku ibu hamil dalam memeriksakan kehamilannya agar dapat terlaksana dengan baik. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang berhubungan dengan cakupan pemberian TTD kepada ibu hamil di Indonesia. Desain penelitian ini yaitu studi ekologi dengan menggunakan data sekunder yang mencakup 34 Provinsi di Indonesia. Jenis data yang digunakan antara lain ketersediaan fasilitas pelayanan kesehatan, ketersediaan tenaga kesehatan, cakupan ANC K1 dan K4, serta alokasi anggaran kesehatan yang bersumber dari, BPS, Dinkes, dan Kemenkes. Uji hubungan yang digunakan yaitu uji pearson. Hasil penelitian menunjukan ketersediaan fasyankes serta cakupan ANC K1 dan K4 memiliki hubungan yang signifikan (p<0,10) dengan cakupan pemberian TTD kepada ibu hamil sedangkan, ketersediaan tenaga kesehatan dan alokasi anggaran kesehatan memiliki hubungan yang tidak signifikan. Ketersediaan puskesmas, posyandu, yaitu dokter obstetri dan ginekologi, tenaga kesehatan masyarakat dan tenaga gizi memiliki hubungan signifikan dengan cakupan pemberian TTD kepada ibu hamil., The coverage of iron supplementation for pregnant women is an indicator of the successful implementation of the program iron supplementation for pregnant women. Implementation of the program requires resources and the role of pregnant women to be implemented properly. This study aims to determine the factors related to the coverage of iron supplementation for pregnant women in Indonesia. The research design used is ecological study and using secondary data covering 34 provinces in Indonesia. The data used includes the availability of health facilities, availability of health workers, coverage of ANC K1 and K4, and the allocation of health budget from BPS, Dinkes, dan Kemenkes. The relationship test used is the pearson test. The results showed that the availability of health facilities and the coverage of ANC K1 and K4 had significant relationship (p<0,10) with the coverage of iron supplementation for pregnant women while, availability of health workers and health budget allocation had insignificant relationship. Puskesmas, posyandu, obstetricians and gynecologists, public health workers, and nutrition workers had a significant relationship with the coverage of iron supplementation for pregnant women are puskesmas and posyandu.

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: 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.
