Judul: DETERMINANT OF STUNTING AMONG CHILDREN AGED 0-23 MONTHS IN INDONESIA IN 2018
Abstrak: Terbentuknya SDM yang berkualitas dimulai dengan mempersiapkan kualitas penerus bangsa, yaitu anak. Stunting merupakan permasalahan gizi pada anak baduta yang ditandai dengan panjang badan atau tinggi badan <-2 SD median standar pertumbuhan anak WHO. Penelitian ini bertujuan untuk menganalisis determinan stunting terdiri dari faktor kesehatan yang termasuk dalam intervensi gizi spesifik pada kelompok 1000 HPK (pemberian TTD pada remaja putri dan ibu hamil, ANC (K4), PMT bagi ibu hamil KEK, imunisasi dasar lengkap pada bayi, IMD, serta ASI Eksklusif), BBLR, dan gizi buruk pada anak usia 0-23 bulan di Indonesia tahun 2018. Desain penelitian yang digunakan adalah studi ekologi. Data penelitian ini berupa data sekunder publikasi Kementerian Kesehatan Republik Indonesia dan BPS tahun 2019 dengan unit analisis 34 Provinsi. Hasil Uji korelasi Pearson menunjukkan ANC (K4), imunisasi dasar lengkap pada bayi, dan gizi buruk pada anak usia 0-23 bulan berhubungan siginifikan terhadap stunting anak usia 0-23 bulan (p<0,05)., The formation of quality human resources begins with preparing the quality of the country's successors, which is children. Stunting is a nutritional problem in children aged 2 years old which is characterized by body length or height <-2 median child growth standards WHO. This study aims to analyze the determinants of stunting consisting of health factors included in specific nutritional interventions in the 1,000 HPK group (giving TTD to adolescent girls and pregnant women, ANC (K4), PMT for SEZ pregnant women, complete basic immunization for infants, IMD, and exclusive breastfeeding), low weight, and malnutrition in children aged 0-23 months in Indonesia in 2018. The research design used was an ecological study. This research data is in the form of secondary data published by the Ministry of Health of the Republic of Indonesia and BPS in 2019 with analysis units of 34 Provinces. The results of the Pearson correlation test showed ANC (K4), complete basic immunization in infants, and malnutrition in children aged 0-23 months were significantly related to stunting of children aged 0-23 months (p<0.05).

Judul: Determinants Factors of Stunting in Children 24-59 Month in Indonesia
Abstrak: Age under five year old is one of the most important periods for a child’s growth and development. This period is important for placing health and intelectual development for a child’s future. Based on that, nutrition problems in childhood are needed to be eliminated. There are many problems in childhood related to nutrition .According to Ministry of Health (2008), there are 36,8% of children were stunted. It is larger than the number of undernourished and wasted children. The objective of this study were : (1) study the family characteristics, infectious diseases, environmental sanitation, hygiene behaviour, access and healthcare utilization, parents’ height and nutritional status according to height-for-age in children; (2) to analyze the relationship between environmental sanitation and healthcare utilization, and between hygiene behaviour and infectious diseases; and (3) to analyze determinant factors of 24-59 months old stunted children. This study used secondary data taken from Basic Health Research 2007 with cross sectional design. Sample size of 42042 children were taken. Pearson’s correlation were used to test relationship among variables. Determinants factors were revealed using SAS program with stepwise method. The results showed that there was a significant relationship (p<0,05) between infectious diseases and sanitation; among infectious diseases and access and healthcare utilization and hygiene behaviour. Factors affecting stunting significantly (p<0,05) were father’s height, mother’s height, age, gender, neighborhood, social and economic status, mother’s education, infectious diseases, personal hygiene, and environmental sanitation.

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.
