Judul: Nutritional Status, Breastfeeding Knowledge, and Breastfeeding Practice in Cirebon Regency
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan status gizi ibu (asupan zat gizi dan indeks massa tubuh) dan pengetahuan ASI dengan praktik menyusui bayi usia 0–6 bulan di Kabupaten Cirebon. Desain penelitian ini adalah cross sectional study dengan jumlah subjek sebanyak 44 orang. Data yang digunakan merupakan data sekunder. Penelitian berlokasi di tiga desa di Kecamatan Gegesik, Kabupaten Cirebon yang merupakan lokus stunting. Sebanyak 47,7% subjek memiliki status gizi normal dan 29,5% subjek memiliki status gizi obesitas. Sebagian besar subjek memiliki tingkat kecukupan energi dan zat gizi yang belum mencapai kebutuhan harian. Sebanyak 63,6% subjek memiliki pengetahuan tentang ASI yang baik dan 43,2% subjek memiliki praktik menyusui yang kurang sesuai. Tidak terdapat hubungan signifikan antara tingkat kecukupan energi dan zat gizi ibu dengan status gizi bayi (p>0,05). Tidak terdapat hubungan signifikan antara karakteristik, status gizi, dan pengetahuan ibu mengenai pemberian ASI dengan praktik menyusui (p>0,05)., The purpose of this study is to analyze the relationship between maternal nutritional status (nutrient intake and body mass index) and breastfeeding knowledge with breastfeeding practices for infants aged 0-6 months in Cirebon Regency. The design of this research is a cross sectional study with a total of 44 subjects. The data used is secondary data. The study is located in three villages in Gegesik District, Cirebon Regency which were the locus of stunting. The amount of 47.7% subjects have normal nutritional status and 29.5% of subjects have obese nutritional status. Most of the subjects had adequate levels of energy and nutrients that had not yet reached their daily needs. The amount of 63.6% subjects have good knowledge of breastfeeding and 43.2% of the subjects have inappropriate breastfeeding. There is no significant relationship between the level of energy and nutritional adequacy of the mother and the nutritional status of the infants (p>0.05). There is no significant relationship between maternal characteristics, nutritional status, and knowledge of breastfeeding with breastfeeding practices (p>0.05).

Abstrak: The direct factors affecting infant’s nutritional status are energy and nutrients intake, and infection. Factors affecting energy and nutrients intake are nutrition knowledge of mother; childcare practices, included feeding and caring practices; and morbidity. The aim of this study was to analyze association between mother’s nutrition knowledge, feeding practices, and immunization with nutritional status of infant. Design of this study was cross sectional. Samples of this study were 60 infants aged 2-24 which were selected purposively. Samples consist of underweight and normal nutritional status (WAZ), The result showed that mother’s nutrition knowledge was positively significant correlated with infant’s nutritional status (r= 0.016 p<0.05). Furthermore, there were positively significant correlation between feeding practices and immunization with infant’s nutritional status( r= 0.031 p<0.05 and p< 0.01, respectively).

Judul: Penggunaan Metode Homotopi untuk Menyelesaikan Persamaan KdV (Korteweg-de Vries)
Abstrak: Natural phenomena can be explained using nonlinear mathematical models. In this paper, we studied the solution of KdV equation using the Homotopy method. The KdV equation is used for describing both surface and internal waves. One of the solutions is called a solitary wave. The use of homotopy method to solve the KdV equation required a nonlinear operator which was determined by the nonlinear form of the KdV equation itself. Based on this operator, a recursive formula was obtained to get a sequence of the KdV solution. The higher the sequence order of the sequence used, the closer to the exact solution of the KdV equation.
