Judul: Ecological Study of Coverage of with the Supplementary Feeding (PMT) for Pregnant Women with SEZ in Indonesia.
Abstrak: Masalah ibu hamil KEK di Indonesia tahun 2022 telah mencapai target nasional ibu hamil KEK (13%) yaitu sebesar 8,43%. Peran pemerintah dalam mengatasi masalah tersebut dengan membentuk Program Pemberian Makanan Tambahan Ibu Hamil KEK. Pemberian makanan tambahan ibu hamil KEK menjadi salah satu rencana aksi untuk mendukung ketercapaian Indonesia Emas 2045 dan tujuan pembangunan bekelanjutan (SDG’s) ke-3 yaitu kesehatan dan kesejahteraan yang baik. Penelitian ini bertujuan menganalisis faktor-faktor yang berhubungan dengan cakupan PMT ibu hamil KEK di Indonesia tahun 2022. Desain penelitian yang digunakan adalah studi ekologi dengan menggunakan data sekunder publikasi dari BPS, Kemenkes RI, dan BKKBN tahun 2022. Hasil uji korelasi Spearmen dalam penelitian menunjukkan cakupan kabupaten/kota minimal 80% posyandu aktif dan ketersediaan tenaga layanan ANC berhubungan signifikan (p=0,024; p=0,039) dengan cakupan PMT ibu hamil KEK di Indonesia. Saran untuk selanjutanya kuantitas dan kualitasnya tempat dan tenaga layanan ANC di setiap provinsi di Indonesia perlu ditingkatkan., The problem of pregnant women with SEZ in Indonesia in 2022 has reached the national target of pregnant women with SEZ (13%), which is 8.43%. The government's role in overcoming this problem is by establishing the Supplementary Feeding Program for Women with SEZ. Supplementary feeding for pregnant women with SEZ is one of the action plans to support the achievement of the Golden Indonesia 2045 and the 3rd sustainable development goal (SDG's), namely good health and well-being. This study aims to analyze the factors associated with PMT coverage of women with SEZ in Indonesia in 2022. The research design used was an ecological study using secondary data publications from BPS, Kemenkes RI, and BKKBN in 2022. Spearmen's correlation test results in the study showed that district/city coverage of at least 80% active posyandu and availability of ANC service personnel were significantly associated (p=0.024; p=0.039) with PMT coverage of women with SEZ in Indonesia. It is suggested that the quantity and quality of ANC centers and personnel in each province in Indonesia should be improved.

Abstrak: Improving the quality of human resources is the main pillar for development, because of the quality of human resources will determine the progress of a nation. The quality of human resources, among others, mirrored by health status, which is determined by the quality of the woman's pregnancy.In this period of pregnant women in dire need of balanced nutrition, good health and correctly in order to pass through a phase of pregnancy optimally. Pregnancy is always associated with the physiological changes that result in an increase in the volume of fluid and red blood cells and a decrease in the concentration of nutrient-binding proteins in the blood circulation, as well as a decrease in micronutrients. When a pregnant woman eating, then in fact there are two bodies that must be fulfilled the need for nutrients, the body of the mother and fetus are always growing and developing. The gestation period is a period of growth and development of the fetus toward the birth so that the nutritional disorder that occurs during pregnancy will impact the health of the mother of the fetus. Some maternal malnutrition during pregnancy include Chronic energy deficiency. Chronic energy deficiency (CED) is a condition in which women experience chronic food shortages lasting (chronic) resulting in impaired - maternal health disorders with signs or symptoms include weakness and pallor (Depkes RI 2003). Based on the results of Health Research (Riskesdas) in 2013, iron deficiency anemia is a public health problem with a prevalence among pregnant women aged 15-49 years at 24.2%. Some provinces showed higher prevalence of national, such as Central Sulawesi, Maluku, Papua and NTT with a prevalence of 45%. (Balitbangkes 2013). Indonesia proportion of the population aged 10-54 years who were pregnant in Indonesia was 2.68 percent, in urban areas (2.8%) higher than in rural areas (2.55%). Different patterns of pregnancy by age group and place of residence. Among the female population aged 10-54 years, there is a pregnancy at a very young age (<15 years), albeit with a very small proportion (0.02%), mainly in rural areas (0.03%). The proportion of pregnancies in teens (15-19 years) was 1.97 per cent, rural (2.71%) higher than in urban areas (1.28%). (Balitbangkes 2013).Specifically, this research aims as follows: (1) Identify the characteristics of pregnant women based in rural, urban and island regions (2) to analyze the prevalence of CED in pregnant women (3) analyze the relationship between the characteristics of pregnant women with CED in rural and urban areas (4) Analyze the determinant CED in pregnant women in rural and urban areas (5) analyze the relationship between the characteristics of pregnant women with CED various islands in Indonesia (6) to analyze the determinants of CED in pregnant women various islands in Indonesia. The data used in this research is secondary data from the Health Research in 2013 (Riskesdas 2013). Riskesdas is a cross-sectional survey design to describe the health problems of the Indonesian population as a whole. The population in this analysis are all pregnant women in Indonesia, which has been recorded by the Central Statistics Agency (BPS). The samples used

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.
