Judul: The Correlation between Mother Nutrition Knowledge and Attitudes, Parenting Styles, and The Nutritional Status of Toddlers in Daycare Participants in the city of Bogor
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan antara pengetahuan, sikap gizi ibu, pola asuh, dan status gizi balita peserta daycare di Kota Bogor. Desain penelitian cross sectional. Subjek berjumlah 40 balita yang dititipkan di daycare Kota Bogor dan penelitian dilaksanakan pada bulan September 2019 hingga Februari 2020. Hasil penelitian menunjukkan sebagian besar ibu balita memiliki pengetahuan gizi dan sikap gizi yang baik. Sebagian besar ibu memiliki pola asuh makan dan pola asuh kesehatan yang baik. Kuantitas pengasuhan ibu pada hari biasa lebih rendah dibandingkan pada hari libur. Tingkat kecukupan energi dan karbohidrat anak cenderung normal, sedangkan tingkat tingkat kecukupan protein dan lemak termasuk dalam kategori lebih. Sebagian besar balita memiliki status gizi baik. Hasil uji korelasi menunjukkan bahwa tidak terdapat hubungan signifikan antara pengetahuan gizi dan pola asuh makan maupun pola asuh kesehatan. Sikap gizi ibu tidak berhubungan dengan pola asuh makan dan pola asuh kesehatan. Hasil uji korelasi juga menunjukkan bahwa tidak terdapat hubungan antara pengetahuan dan sikap gizi, pola asuh ibu dengan status gizi balita., This study aims to analyze the correlation between mother nutrition knowledge and attitudes, parenting style, and nutritional status of toddler daycare participants in Bogor. The design of this study was cross sectional study involved 40 toddlers daycare and was conducted from September 2019 until February 2020. The results showed that most of mothers have good nutritional knowledge and attitudes. Most mothers have good feeding style and parenting in toddlers health. Most of mothers have a low quantity of parenting on weekday. Toddlers's energy and carbohydrate adequacy levels tend to be normal, while the level of nutrient adequacy of proteins and fats tends to be excess. Most toddlers had normal nutritional status. The results of the correlation test showed that there were no significant correlation between Mother Nutrition Knowledge and Attitudes with parenting styles, The results of the correlation test showed that there were no significant correlation between nutrition knowledge and attitudes, parenting styles, and nutritional status of toddlers.

Judul: The Correlation between Mothers’ Child-Parenting Feeding and Physical Activity, with Toddler’s Nutritional Status on Working and non-Working Mothers
Abstrak: ABSTRAK GRACIA INDRIANA KEMBAREN. Hubungan antara Pola Asuh Makan dan Aktivitas Fisik, dengan Status Gizi Anak Balita pada Ibu Bekerja dan Tidak Bekerja. Dibimbing oleh IKEU EKAYANTI. Penelitian ini bertujuan untuk mengkaji hubungan pola asuh makan dan aktivitas fisik, dengan status gizi anak balita pada kelompok ibu bekerja dan ibu tidak bekerja. Metode penelitian yang digunakan adalah cross sectional dengan subjek berjumlah 60 balita yang dibagi kedalam dua kelompok, yaitu 24 balita pada kelompok ibu bekerja dan 36 balita pada kelompok ibu tidak bekerja. Subjek adalah balita dengan usia 2-5 tahun. Tempat penelitian dipilih secara purposive di Kecamatan Rancabungur. Penelitian dilaksanakan pada bulan April hingga Mei 2020, Hasil uji korelasi menunjukkan bahwa karakteristik subjek (usia) dan karakteristik keluarga (pendidikan ibu, besar keluarga, pendapatan perkapita keluarga) berhubungan dengan pola asuh makan (p<0,05). Pola asuh makan tidak berhubungan dengan asupan zat gizi (p=0,358, r=0,121). Hasil uji korelasi menunjukkan bahwa asupan energi tidak berhubungan dengan status gizi BB/TB (p=0,305, r=0,135). Asupan protein tidak berhubungan dengan status gizi TB/U (p=0,915, r=0,014). Hasil uji korelasi menunjukkan bahwa aktivitas fisik tidak berhubungan dengan status gizi balita (p=0,120, r=0,263)., ABSTRACT GRACIA INDRIANA KEMBAREN. The Correlation between Mothers’ Child-Parenting Feeding and Physical Activity, with Toddler’s Nutritional Status on Working and non-Working Mothers. Supervised by IKEU EKAYANTI. This research aimed to analyze the correlation between mothers’ child-parenting feeding and physical activity, with toddler’s nutritional status on working and non-working mothers. The study design was cross sectional with 60 toddlers, divided into two groups; 24 toddlers of working mother and 36 toddlers of non-working mother. The subjects were toddler from 2-5 years. The place were selected purposively in Rancabungur district. The research conducted in April until May 2020, The results of the correlation test showed that the characteristics of the subject (age) and the family (mothers’ education, number of family, family’s income percapita) were related to the feeding pattern (p<0,05). Feeding pattern was not related to nutrient intake (p=0,358, r=0,121). The results of the correlation test showed that energy intake was not related to the nutritional status of WHZ index (p=0,305, r=0,135). Protein intake was not related with nutritional status of HAZ index (p=0,915, r=0,014). The results of the correlation test showed that physical activity does not have a relationship with the nutritional status of toddler (p=0,120, r=0,263).

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.
