Judul: Cultural Taboos and Eating Patterns with Food Diversity and Nutritional Status of Toddlers in The Dayak Tribe
Abstrak: Pertumbuhan dan perkembangan balita sangat dipengaruhi oleh kualitas gizi yang diberikan. Indikator yang dapat digunakan untuk mengetahui tumbuh kembang anak adalah status gizi. Tujuan dari penelitian ini adalah untuk menganalisis hubungan budaya pantangan makan dan pola asuh makan dengan keragaman pangan dan status gizi balita di Suku Dayak Provinsi Kalimantan Timur. Desain penelitian yang digunakan adalah cross sectional study. Penelitian dilaksanakan pada bulan Desember 2023 pada 100 balita bersuku Dayak. Penelitian telah lolos kaji etik dengan nomor 1098/IT3.KEPMSM-IPB/SK/2023. Pengumpulan data dilakukan dengan tiga metode yaitu wawancara, pengisian kuesioner, dan pengukuran antropometri secara langsung. Penelitian menunjukkan sebagian besar subjek tidak melakukan budaya pantangan makan (80%). Hampir seluruh subjek memiliki pola asuh makan yang tepat (97%). Keragaman pangan subjek sebagian besar terkategori sedang (50%). Status gizi subjek sebagian besar normal, tetapi masih terdapat balita dengan status gizi underweight (18%), stunting (24%), dan wasting (17%). Uji korelasi menunjukkan adanya hubungan yang signifikan antara pola asuh makan dengan keragaman pangan (p= 0,006). Selain itu, didapatkan hubungan yang signifikan antara keragaman pangan dengan status gizi balita TB/U (p= 0,020). Tetapi, tidak ditemukan hubungan signifikan antara budaya pantangan makan dan pola asuh makan dengan keragaman pangan dan status gizi pada indikator lain yang tidak disebutkan., The growth and development of toddlers are greatly influenced by the quality of nutrition provided. An indicator that can be used to assess child growth and development is nutritional status. The aim of this study is to analyze the relationship between food taboos and feeding parenting practices with dietary diversity and nutritional status of toddlers in the Dayak tribe of East Kalimantan Province. The research design used is a cross-sectional study. The study was conducted in December 2023 on 100 Dayak toddlers. The study has passed ethical review with the number 1098/IT3.KEPMSM-IPB/SK/2023. Data collection was carried out using three methods: interviews, questionnaires, and direct anthropometric measurements. The study showed that the majority of subjects did not practice food taboos (80%). Nearly all subjects had appropriate feeding parenting practices (97%). Most subjects had a moderate level of dietary diversity (50%). The nutritional status of most subjects was normal, but there were still toddlers with underweight (18%), stunting (24%), and wasting (17%) statuses. Correlation tests showed a significant relationship between feeding parenting practices and dietary diversity (p= 0.006). Additionally, a significant relationship was found between dietary diversity and the nutritional status of toddlers based on height-for-age (p= 0.020). However, no significant relationship was found between food taboos and feeding parenting practices with dietary diversity and other nutritional status indicators not mentioned.

Judul: Analysis of Food Consumption, Parenting Pattern and Nutritional Status of Toddler from The Family Program of Hope in Harau, Limapuluh Kota District
Abstrak: Keterbatasan akses terhadap pangan berpengaruh terhadap kualitas dan kuantitas konsumsi pangan rumah tangga. Penelitian ini bertujuan untuk menganalisis kualitas konsumsi pangan keluarga, kuantitas konsumsi zat gizi balita, pola asuh ibu, dan hubungannya dengan status gizi balita KPM PKH di Kecamatan Harau. Penelitian cross sectional study dilakukan pada bulan Maret hingga Juni 2021 pada 90 subjek. Data diperoleh dari hasil wawancara berdasarkan kuesioner, Food recall, dan HDDS. Subjek memiliki kualitas konsumsi yang tergolong tinggi (97,8%), tingkat kecukupan energi defisit (40,0%), tingkat kecukupan protein lebih (84,4%), Tingkat kecukupan zat besi (56,7%), vitamin A (98,9%), dan zinc (68,9%) cukup. Pola asuh ibu subjek tergolong baik (54,4%). Status gizi subjek yaitu berat badan normal (78,9%), tinggi normal (72,2%), gizi baik berdasarkan BB/TB (81,1%), dan gizi baik berdasarkan IMT/U (82,2%). Tidak terdapat hubungan yang signifikan antara pola asuh, kualitas konsumsi, dan kuantitas konsumsi dengan status gizi subjek (p>0,05)., Limited access to food affects the quality and quantity of household food consumption. This study aims to analyze the quality of family food consumption, quantity of nutritional consumption of children under five, mother's parenting, and its relationship with the nutritional status of toddlers from the family who get the benefit from family program of hope. in Harau District. The cross sectional study was conducted in March to June 2021 on 90 subjects. Data obtained from interviews based on questionnaires, Food recall, and HDDS. Subjects had a high quality of consumption (97.8%), a level of energy deficit adequacy (40.0%), an excess level of protein adequacy (84.4%), a sufficient level of iron (56.7%), vitamin A (98.9%), and zinc (68.9%) was sufficient. The subject's mother's parenting pattern is classified as good (54.4%). The nutritional status of the subjects were normal weight (78.9%), normal height (72.2%), good nutrition based on WHZ (81.1%), and good nutrition based on BAZ (82.2%). There is no significant relationship between parenting, quality of consumption, and quantity of consumption with the nutritional status of the subject (p>0.05).

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.
