Judul: The Relationship of Availability, Access, and Consumption of Animal Food with Stunting in South Sulawesi 2018-2019
Abstrak: Parameter yang digunakan untuk mengetahui pemenuhan kebutuhan gizi adalah melalui ketahanan pangan. Tiga pilar ketahanan pangan dapat dinilai dengan mengetahui ketersediaan, konsumsi, dan akses pangan. Salah satu permasalahan gizi yang muncul akibat kurangnya konsumsi pangan adalah stunting, dan salah satu wilayah dengan prevalensi stunting yang tinggi adalah Sulawesi Selatan yaitu 35,7% pada tahun 2018. Jenis pangan hewani berkontribusi besar dalam upaya pencegahan stunting. Penelitian ini bertujuan untuk mengetahui hubungan ketersediaan, akses, dan konsumsi pangan hewani dengan stunting di Sulawesi Selatan. Data yang digunakan adalah data sekunder dari Badan Pusat Statistik (BPS), dan Dinas Kesehatan. Data tersebut diolah dan dianalisis dengan Excel, Neraca Bahan Makanan (NBM), dan SPSS secara deskriptif dan inferensia. Hasil penelitian ini menunjukkan bahwa secara umum, ketersediaan pangan hewani di Sulawesi Selatan sudah baik. Akses fisik, akses ekonomi, serta akses sosial masih mengalami fluktuasi ditahun 2018-2019. Konsumsi pangan hewani terkategori rendah untuk kecukupan energi dan terkategori baik untuk kecukupan protein. Uji korelasi menunjukkan terdapat hubungan signifikan antara persentase penduduk miskin (p=0,001) dan persentase penduduk buta huruf (p<0,1) dengan stunting, dan tidak terdapat hubungan signifikan antara ketersediaan dan konsumsi pangan hewani, serta persentase rumah tangga aliran listrik dan proporsi pengeluaran pangan hewani., The parameter to determine the fulfillment of nutritional needs is food security. Three pillars of food security can be assessed by knowing the availability, consumption, and access of food. A nutritional problem that arises due to lack of food consumption is stunting, and one of the areas with a high prevalence of stunting is South Sulawesi, namely 35.7% in 2018. Types of animal foods contribute greatly to stunting prevention efforts. This study aims to determine the relationship between availability, access, and consumption of animal food with stunting in South Sulawesi. The data used are secondary data from the BPS and the Health Office. The data were processed and analyzed using Excel, NBM, and SPSS descriptively and inferentially. The results of this study indicate that the availability of animal food in South Sulawesi is good. Physical, economic, and social access still fluctuated. Consumption of animal food is categorized as low for energy adequacy and in the good category for protein adequacy. The correlation test showed that there was a significant relationship between the percentage of the poor (p=0.001) and the percentage of the illiterate population (p<0.1) with stunting, and there was no significant relationship between the availability and consumption of animal food, as well as the percentage of households without electricity and proportion of animal food expenditure.

Judul: Analysis of Socio-economic Factors Associated with  Animal-based Food Consumption in Indonesia
Abstrak: Konsumsi pangan hewani dalam jumlah cukup dinilai penting untuk membantu mencegah terjadinya masalah gizi termasuk stunting. Faktor sosial ekonomi menjadi salah satu faktor yang dapat mempengaruhi konsumsi pangan hewani penduduk. Penelitian ini bertujuan untuk menganalisis hubungan antara berbagai faktor sosial ekonomi terhadap konsumsi pangan hewani di Indonesia. Desain penelitian ini adalah cross sectional menggunakan data sekunder dari 34 provinsi di Indonesia yang mencakup data jumlah penduduk, rata-rata lama sekolah, PDRB per kapita, pendapatan riil, tingkat kemiskinan, tingkat pengangguran, dan konsumsi pangan hewani. Penelitian dilakukan pada bulan April-September 2021. Hasil analisis regresi linear berganda menunjukkan bahwa PDRB per kapita dan tingkat pengangguran memiliki hubungan positif (p<0,05), sedangkan jumlah penduduk dan tingkat kemiskinan berhubungan negatif dengan konsumsi pangan hewani (p<0,05). Upaya untuk mengontrol jumlah yang bertujuan untuk mengurangi tingkat kemiskinan dan pengangguran, serta stabilitas ekonomi diperlukan untuk meningkatkan GDRP yang selanjutnya menjamin pemenuhan konsumsi pangan., To avoid nutrition disorders, including as stunting, adequate animal-based food consumption is required. Various socioeconomic factors may influence the community's intake of animal-based foods. The goal of this study was to look at the socioeconomic aspects that influence animal-based food intake in Indonesia. The study was cross-sectional and included secondary data from 34 Indonesian provinces, including information on population, mean school years, GDRP per capita, real income per capita, poverty level, unemployment rate, and animal-based food consumption. The research took place from April to September of 2021. Multiple linear regression analysis revealed significant positive relationships between GRDP per capita and unemployment rate and animal-based food consumption (p<0.05), but substantial negative relationships between population and poverty rates and animal-based food consumption (p<0.05). To increase GRDP and assure food consumption, population restrictions aimed at lowering poverty and unemployment rates, as well as macroenonomic stability, are required.

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.
