Judul: The Influence of Economic Pressure and Financial Management on Parenting Quality in Stunting Children
Abstrak: Stunting menjadi permasalahan multidimensi yang tidak hanya berkaitan dengan faktor gizi dan kesehatan, tetapi juga faktor pengasuhan. Kualitas pengasuhan memegang peranan penting dalam mendukung pemenuhan kebutuhan tumbuh kembang anak yang optimal. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik anak, karakteristik keluarga, tekanan ekonomi, dan manajemen keuangan terhadap kualitas pengasuhan. Penelitian dilakukan dengan pendekatan kuantitatif dan desain cross sectional study. Penelitian melibatkan 68 ibu dari keluarga utuh dengan anak stunting berusia 24-59 bulan dan berdomisili di Kecamatan Tanjungsari, Kabupaten Sumedang, Provinsi Jawa Barat. Responden penelitian diperoleh melalui non-probability sampling dengan teknik purposive sampling. Hasil penelitian menunjukkan bahwa tekanan ekonomi dan manajemen keuangan keluarga berada pada kategori sedang, sementara kualitas pengasuhan terkategori rendah. Usia anak, lama pendidikan ibu dan ayah, serta manajemen keuangan berhubungan positif signifikan dengan kualitas pengasuhan, sedangkan tekanan ekonomi berhubungan negatif signifikan dengan kualitas pengasuhan. Hasil uji regresi menunjukkan bahwa usia anak dan manajemen keuangan berpengaruh positif signifikan terhadap kualitas pengasuhan, sementara tekanan ekonomi berpengaruh negatif signifikan terhadap kualitas pengasuhan., Stunting is a multi-dimensional problem that is not only related to nutrition and health factors, but also parenting factors. The quality of parenting plays an important role in supporting the fulfillment of children's optimal growth and development needs. This study aims to analyze the influence of child characteristics, family characteristics, economic pressure, and financial management on the quality of parenting. The research was conducted using a quantitative approach and cross-sectional study design. This study involved 68 mothers from intact families with stunted children aged 24-59 months and residing in Tanjungsari District, Sumedang Regency, West Java Province. Respondents were obtained through non-probability sampling with purposive sampling technique. The results showed that the economic pressure and the financial management were categorized as moderate, while the quality of parenting are in the low category. A child's age, parent’s education, and the financial management are significantly positive related to parenting quality, while the economic pressure is significantly negative related to parenting quality. The regression test results show that the child’s age and the financial management have a significant positive effect on parenting quality, while the economic pressure has a significant negative effect on parenting quality.

Judul: Effect of Food Consumption, Health, Education, and Economic Factors on Stunting in West Java
Abstrak: Stunting merupakan masalah gizi yang dialami oleh balita di Provinsi Jawa Barat dengan prevalensi sebesar 26,1%. Berdasarkan WHO conceptual framework, faktor penyebab stunting terbagi atas causes dan context. Penelitian ini bertujuan menganalisis konsumsi pangan sebagai cause, faktor kesehatan, pendidikan, dan ekonomi sebagai context serta pengaruhnya terhadap prevalensi stunting di Jawa Barat. Desain penelitian ini adalah ecological study menggunakan data sekunder yang dipublikasi pada tahun 2018-2019 dengan unit analisis 18 kabupaten dan 9 kota. Metode analisis yang digunakan adalah analisis deskriptif dan regresi data panel. Hasil penelitian menunjukan konsumsi pangan penduduk berupa tingkat kecukupan energi dan protein tergolong normal, namun skor Pola Pangan Harapan belum mencapai 100. Terjadi perkembangan pada faktor kesehatan meliputi usia harapan hidup, jumlah sarana, tenaga dan jaminan kesehatan, serta faktor pendidikan meliputi harapan lama sekolah, rata-rata lama sekolah, jumlah sarana dan tenaga pendidikan. Faktor ekonomi seperti skor Indeks Pembangunan Manusia, pengeluaran perkapita disesuaikan dan pengeluaran pangan mengalami perkembangan, sedangkan ketimpangan pendapatan dan persentase penduduk miskin mengalami penurunan. Hasil penelitian menunjukkan tingkat kecukupan energi, jumlah sarana kesehatan, dan indeks gini berpengaruh positif signifikan terhadap prevalensi stunting, sedangkan tingkat kecukupan protein, usia harapan hidup, jumlah tenaga dan jaminan kesehatan berpengaruh negatif signifikan terhadap prevalensi stunting di Provinsi Jawa Barat. Kata kunci: ekonomi, kesehatan, konsumsi pangan, stunting, Effect of Food Consumption, Health, Education, and Economic Factors on Stunting in West Java. Supervised by YAYUK FARIDA BALIWATI. Stunting is a nutritional problem experienced by toddlers in West Java with prevalence of 26.1%. Based on WHO conceptual framework, the causes of stunting are divided into causes and context. This study aims to analyze food consumption as cause, health, education and economic factors as context and its influence on stunting prevalence in West Java. Design of this research is ecological study using secondary data published in 2018-2019. The analytical method is descriptive analysis and panel data regression. The results showed that energy and protein aduquacy level was normal, but Desirable Dietary Pattern Score had not yet reached 100. There were developments in health factors including life expectancy, personnel and health insurance, as well as educational factors including expected years school, mean years school, number of facilities and education personnel. Economic factors such as Human Development Index score, purchasing power parity and food expenditure have developed, while income inequality and the percentage of poor have decreased. The results showed that the energy adequacy level, number of health facilities, and Gini index had significant positive effect on stunting prevalence, while protein adequacy level, life expectancy, number of personnel and health insurance had significant negative effect on stunting prevalence in West Java.

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.
