Judul: Analysis of Regional Food Availability and Consumption with Prevalence of Stunting in Sumedang Regency 2018-2020
Abstrak: Stunting menjadi salah satu masalah gizi yang menjadi perhatian utama pemerintah di Indonesia untuk diamati dan diatasi. Masalah gizi stunting dipengaruhi oleh banyak faktor teramasuk dimensi ketahanan pangan, yaitu ketersediaan dan konsumsi pangan. Penelitian ini bertujuan menganalisis ketersediaan dan konsumsi pangan wilayah serta prevalensi stunting di Kabupaten Sumedang. Data yang diolah merupakan data sekunder dari dinas-dinas terkait di Kabupaten Sumedang pada tahun 2018-2020. Data disajikan secara deskriptif. Hasil analisis menunjukkan ketersediaan pangan dari segi kuantitas tergolong dalam kategori surplus. Kondisi konsumsi pangan wilayah dari segi kuantitas tergolong kategori baik untuk konsumsi energi dan lebih untuk konsumsi protein. Ketersediaan dan konsumsi pangan wilayah Kabupaten Sumedang masih dari segi kualitas masih belum beragam. Prevalensi stunting di Kabupaten Sumedang selama tahun 2018-2020 cenderung berfluktuatif, dan mengalami peningkatan sebesar 4,18 persen pada tahun 2020. Ketersediaan pangan wilayah dari segi kuantitas dan kualitas memiliki kecenderungan hubungan negatif dengan prevalensi stunting. Terdapat kecenderungan negatif antara konsumsi protein dan kualitas konsumsi pangan dengan prevlensi stunting. Terdapat kecenderungan hubungan positif antara konsumsi energi dan tingkat kemiskinan dengan prevalensi stunting., Stunting is one of the nutritional problems that is the main concern of the government in Indonesia to be observed and overcome. The problem of stunting nutrition is influenced by many factors including the dimension of food security, namely food availability and consumption. This study aims to analyze the availability and consumption of regional food with the prevalence of stunting in Sumedang Regency. The data processed is secondary data from related agencies in Sumedang Regency in 2018-2020. The data is presented descriptively. The results of the analysis show that food availability in terms of quantity is classified as a surplus. The condition of regional food consumption in terms of quantity is classified as a good category for energy consumption and more for protein consumption. The availability and consumption of food in Sumedang Regency is still not diverse in terms of quality. The prevalence of stunting in Sumedang Regency during 2018-2020 tends to fluctuate, and has increased by 4.18 percent. Regional food availability in terms of quantity and quality has a tendency to be negatively related to the prevalence of stunting. There is a negative trend between protein consumption and the quality of food consumption with the prevalence of stunting. There is a positive relationship between energy consumption and poverty rates and stunting prevalence.

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: 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.
