Judul: Exclusive Breastfeed History, Nutritional Status, and Anemia Status of Toddler at Gegesik Cirebon Regency
Abstrak: Tujuan penelitian ini adalah menganalisis hubungan riwayat mendapat ASI eksklusif terhadap status gizi dan status anemia balita di kecamatan Gegesik kabupaten Cirebon. Desain penelitian yang digunakan adalah cross sectional. Penelitian dilakukan di tiga desa yaitu Desa Sibubut, Desa Kedungdalem, dan Desa Bayalangu Kidul, Kecamatan Gegesik Kabupaten Cirebon Provinsi Jawa Barat. Penelitian ini menggunakan data sekunder dengan jumlah subjek 119 balita. 52,1% balita berjenis kelamin perempuan dan berusia 12-23 bulan. Sebagian besar balita lahir dengan berat dan panjang yang normal. Masih terdapat 28,6% balita yang tidak mengonsumsi kolostrum dan hanya sedikit balita yang mengonsumsi ASI secara eksklusif, karena mengonsumsi makanan prelakteal, dan mengomsumsi MPASI terlalu dini. Sebagian besar balita memiliki status gizi normal berdasarkan indikator BB/U, TB/U, BB/TB, akan tetapi masih terdapat balita dengan berat badan kurang (34,5%) dan berat badan sangat kurang (8,4%), balita stunting (39,5%), serta balita dengan gizi kurang (16%) dan gizi buruk (4,2%). Terdapat 89,1% balita berstatus anemia dan paling banyak memiliki anemia kategori sedang. Hasil uji hubungan Spearman menunjukkan tidak terdapat hubungan yang signifikan antara pemberian ASI eksklusif dengan status gizi dan status anemia balita (p value>0,05)., This research aims to analyze the correlation between the history of exclusive breastfeeding with toddlers’ nutritional status and anaemia status in Gegesik, Cirebon Regency. This research design used a cross-sectional which was conducted in three villages namely Sibubut village, Kedungdalem village, and Bayalangu Kidul village, in Gegesik District, Cirebon Regency, West Java Province. The data was obtained through secondary data by including 119 toddlers which 52.1 % were female and aged 12-23 months. Most toddlers are born with a normal weight and length. Then 28.6 % of toddlers are not consuming colostrum. Therefore, only a few toddlers receive exclusively breastfeeding because they have to consume prelakteal food and complementary feeding over-early. Based on indicators of W/A, H/A, and W/H, which reveal most toddlers have a normal nutritional status, on the other hand, there are toddlers with underweight (34.5%), severely weight (8.4%), stunting (39.5%), likewise toddlers with wasting (16%), and severely wasting (4.2%). There are 89.1% of toddlers were classified as anaemia and most were in a mild category. The finding of the Spearman Correlation Test reveals that was no significant correlation between exclusive breastfeeding with nutritional status and anaemia status of toddlers (p value> 0.05).

Judul: Children Feeding Practices, Food Consumption, and  Toddlers Anemia Status in Locus Stunting Village Cirebon Regency
Abstrak: Anemia merupakan masalah gizi global dengan prevalensi 36,78% balita di Indonesia mengalami anemia. Konsumsi pangan adalah faktor utama yang mempengaruhi status anemia. Pola asuh makan juga berkontribusi dalam pembentukan pola konsumsi makan balita. Penelitian ini bertujuan menganalisis hubungan pola asuh makan dengan konsumsi pangan balita, dan hubungan karakteristik balita, pola asuh makan, dan konsumsi pangan dengan status anemia balita. Desain penelitian yang digunakan adalah cross sectional study dan menggunakan data sekunder. Jumlah subjek penelitian sebanyak 130 balita usia 6– 59 bulan. Penelitian berlokasi di 3 desa di Kecamatan Gegesik, Kabupaten Cirebon yang merupakan lokus stunting. Anemia yang terjadi pada penelitian ini mencapai 87,7% dengan tingkat keparahan paling banyak yaitu anemia tingkat sedang (75,4%). Perbedaan signifikan antara kelompok balita anemia dan tidak anemia terdapat pada variabel: berat lahir (p-value=0,010), pekerjaan ibu (p-value=0,027), tingkat kecukupan energi (p-value=0,028), tingkat kecukupan protein (p-value= 0,040), tingkat kecukupan lemak (p-value=0,002), dan tingkat kecukupan Fe (p value= 0,000). Tidak terdapat hubungan signifikan (p-value>0,05) antara pola asuh makan dengan konsumsi pangan balita. Faktor yang berhubungan dengan status anemia balita adalah usia balita (r=-0,173; p-value=0,049), tingkat kecukupan Fe (r=0,179; p-value=0,042), konsumsi hati ayam (r=0,190; p-value=0,030), dan konsumsi telur (r=-0,207; p-value=0,018)., Anemia is global nutritional problem with a prevalence of 36,78% of toddlers in Indonesia experiencing anemia. Food consumption is the main factor that affect anemia. Children feeding practices also contribute to formation of food consumption patterns in toddlers. This study aims to analyze the correlation between children feeding practices and food consumption for toddlers, and the relationship between toddlers characteristics, children feeding practices, and food consumption with toddlers anemia status. This research uses a cross sectional design and secondary data. The number of research subjects was 130 toddlers aged 6-59 months. The study was located in 3 villages in Gegesik District, Cirebon Regency which were locus of stunting. Anemia that occurred reached 87,7% with the highest severity is moderate anemia (75,4%). Significant differences between anemic and non-anemic toddlers groups were found in variables: birth weight (p value=0,010), mother's occupation (p-value=0,027), energy adequacy level (p value=0,028), protein adequacy level (p-value=0,040), fat adequacy level (p-value= 0,002), and iron adequacy level (p-value=0,000). There is no significant relationship (p-value>0,05) between children feeding practices and food consumption in toddlers. Factors related to anemia status of toddlers are toddler’s age (r=-0,173; p-value=0,049), iron adequacy level (r=0,179; p-value=0,042), chicken liver consumption (r=0,190; p-value=0,030), and egg consumption (r=- 0,207; p-value=0,018).

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.
