Judul: Factors Related to the Coverage of Iron Supplementation for Pregnant Woman in Indonesia
Abstrak: Cakupan pemberian TTD kepada ibu hamil merupakan salah satu indikator keberhasilan pelaksanaan program pemberian TTD kepada ibu hamil. Pelaksanaan program tersebut memerlukan sumber daya dan perilaku ibu hamil dalam memeriksakan kehamilannya agar dapat terlaksana dengan baik. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang berhubungan dengan cakupan pemberian TTD kepada ibu hamil di Indonesia. Desain penelitian ini yaitu studi ekologi dengan menggunakan data sekunder yang mencakup 34 Provinsi di Indonesia. Jenis data yang digunakan antara lain ketersediaan fasilitas pelayanan kesehatan, ketersediaan tenaga kesehatan, cakupan ANC K1 dan K4, serta alokasi anggaran kesehatan yang bersumber dari, BPS, Dinkes, dan Kemenkes. Uji hubungan yang digunakan yaitu uji pearson. Hasil penelitian menunjukan ketersediaan fasyankes serta cakupan ANC K1 dan K4 memiliki hubungan yang signifikan (p<0,10) dengan cakupan pemberian TTD kepada ibu hamil sedangkan, ketersediaan tenaga kesehatan dan alokasi anggaran kesehatan memiliki hubungan yang tidak signifikan. Ketersediaan puskesmas, posyandu, yaitu dokter obstetri dan ginekologi, tenaga kesehatan masyarakat dan tenaga gizi memiliki hubungan signifikan dengan cakupan pemberian TTD kepada ibu hamil., The coverage of iron supplementation for pregnant women is an indicator of the successful implementation of the program iron supplementation for pregnant women. Implementation of the program requires resources and the role of pregnant women to be implemented properly. This study aims to determine the factors related to the coverage of iron supplementation for pregnant women in Indonesia. The research design used is ecological study and using secondary data covering 34 provinces in Indonesia. The data used includes the availability of health facilities, availability of health workers, coverage of ANC K1 and K4, and the allocation of health budget from BPS, Dinkes, dan Kemenkes. The relationship test used is the pearson test. The results showed that the availability of health facilities and the coverage of ANC K1 and K4 had significant relationship (p<0,10) with the coverage of iron supplementation for pregnant women while, availability of health workers and health budget allocation had insignificant relationship. Puskesmas, posyandu, obstetricians and gynecologists, public health workers, and nutrition workers had a significant relationship with the coverage of iron supplementation for pregnant women are puskesmas and posyandu.

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.

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.
