Judul: Correlation between Mother's Nutritional Knowledge, Parental Dietary Pattern, and Nutritional Status of Toddlers with Adolescent Mothers
Abstrak: Provinsi Jawa Barat merupakan salah satu provinsi di Indonesia dengan persentase pernikahan usia dini tertinggi. Tingginya angka pernikahan usia dini tersebut menyebabkan banyak terjadinya ibu dengan kehamilan pertama di usia remaja. Psikososial pada remaja putri belum siap untuk menjalankan peran menjadi seorang ibu yang dapat mendorong terjadinya pola asuh penelantaran sehingga anak kurang perhatian dan kurang asupan makanan yang bergizi seimbang. Pengetahuan gizi ibu yang kurang akan mempengaruhi praktik pemberian makanan yang tidak tepat. Asupan gizi yang baik, tidak hanya dipengaruhi oleh ketersediaan pangan yang memadai saja tetapi dipengaruhi juga oleh pola asuh yang baik. Penelitian ini bertujuan menganalisis hubungan antara pengetahuan gizi ibu, pola asuh makan dan status gizi baduta dengan ibu remaja. Desain penelitian yang digunakan, yaitu cross sectional study. Penelitian ini dilaksanakan di Kecamatan Gebang, Kabupaten Cirebon. Jumlah subjek penelitian sebanyak 44 baduta berusia 6-24 bulan. Hasil penelitian menunjukkan bahwa terdapat hubungan signifikan positif antara pengetahuan gizi ibu remaja dengan pola asuh makan (p<0,05) dan terdapat hubungan signifikan negatif antara pengetahuan gizi ibu remaja dengan status gizi baduta berdasarkan indeks BB/U dan TB/U (p<0,05)., West Java is one of provinces in Indonesia with highest percentage of early marriage. The high rate of early marriage causes many mothers to have their first pregnancies in their teens. From a psychosocial perspective, female teenagers are generally not ready to assume the role of being a mother which can lead to neglect of parenting so that the child is less attentive and less likely to feed them a balanced and nutrious diet. Lack of mother’s nutritional knowledge will affect inappropriate feeding practices. Good nutritional intake is not only influenced by adequate food availability but is also influenced by good parenting. This study aims to analyze correlation between mother’s nutritional knowledge, parental dietary pattern and nutritional status of toddlers with adolescent mothers. The research design used was a cross sectional study. The research was conducted in Gebang District, Cirebon Regency. The number of research subjects was 44 toddlers aged 6-24 months. The results showed that there was a significant positive correlation between mother’s nutritional knowledge and parental dietary pattern with adolescent mothers (p<0,05) and there was a significant negative correlation between mother’s nutritional knowledge and nutritional status of toddlers based on index of weight/age and height/age with adolescent mothers (p<0,05).

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.
