Judul: Nutritional Fulfillment of Children Under Three in Stunting Area of Kepung Public Health Center, Kediri Regency
Abstrak: Stunting merupakan masalah yang belum terpecahkan di Indonesia. Penelitian ini bertujuan untuk mengetahui pelaksanaan pemenuhan gizi batita stunting dan normal di Desa Besowo. Penelitian ini merupakan studi case control dengan 38 anak usia 19-36 bulan yang dipilih melalui total sampling dan secara purposive. Pengumpulan data dilakukan dengan mengukur antropometri contoh dan wawancara dengan ibu contoh. Berat badan lahir rendah (BBLR) (15,8%) dan panjang badan lahir pendek (26,3%) (p=0,016) ditemukan pada kelompok stunting. Tidak ada perbedaan yang signifikan pada karakteristik orang tua (p>0,05). Karakteristik sosial ekonomi kedua kelompok cenderung homogen (p>0,05). Tidak ada perbedaan signifikan riwayat konsumsi suplemen pada ibu contoh selama kehamilan antara kedua kelompok (p>0,05). Lebih banyak kelompok stunting yang mendapatkan inisiasi menyusu dini (IMD) (p=0,027). Sebagian besar riwayat pemberian ASI eksklusif tidak diberikan pada kedua kelompok (p>0,05). Konsumsi kelompok pangan daging-dagingan berbeda nyata di kedua kelompok (p=0,027). Tingkat kecukupan zat gizi konsumsi contoh (p>0,05), keragaman pangan (p>0,05) dan pengetahuan, sikap, dan perilaku gizi ibu contoh tidak berbeda nyata (p>0,05). Subjek pada kelompok stunting yang mendapat IMD sebagian besar tidak mendapatkan ASI eksklusif. Oleh karena itu, intervensi yang menekankan pada pengetahuan gizi harus ditujukan untuk mengatasi faktor-faktor yang mempengaruhi pemberian ASI eksklusif dan praktik pemberian makanan., Stunting is an unsolved problem in Indonesia. This study aims to determine the nutritional fulfillment of stunting and normal toddlers in Besowo Village. This is a case control study with 38 subjects aged 19-36 months selected through total sampling and purposively. Data was collected by measuring anthropometric and interviewing the sample mothers. Low birth weight (LBW) (15.8%) and short birth length (26.3%) (p=0.016) were found in the stunting group. There was no significant difference of parents’ characteristics (p>0.05). Socio-economic characteristics of the two groups tended to be homogeneous (p>0.05). There was no significant difference in the history of supplement consumption during pregnancy between the two groups (p>0.05). More stunting group received early initiation of breastfeeding (EIB) (p=0.027). Mostly exclusive breastfeeding was not given to both groups (p>0.05). The consumption of the flesh food was significantly different between two groups (p=0.027). The level of nutritional adequacy of subject’s consumption (p>0.05), food diversity (p>0.05) and the nutritional knowledge, attitudes and behavior of the subject’s mothers were not significantly different (p>0.05). Most of the subjects in the stunting group who received EIB did not exclusively breastfeed. Therefore, interventions emphasizing nutritional knowledge should address the factors influencing exclusive breastfeeding and feeding practices.

Judul: The Correlation between Breastfeeding and Complementary Feeding Practices with Stunting of Children Aged 6-23 Months in Kupang District
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan praktik pemberian ASI dan MP-ASI dengan stunting pada baduta usia 6–23 bulan di Kabupaten Kupang. Desain penelitian ini adalah cross sectional study dengan jumlah subjek sebanyak 1404 baduta yang dipilih dengan purposive sampling. Penelitian ini menggunakan data sekunder dari penelitian Better Investment for Stunting Alleviation (BISA) 2020. Sebanyak 17,9% subjek tergolong severe stunting dan 19,6% subjek tergolong stunting. Hasil uji hubungan menunjukkan adanya hubungan signifikan antara usia, jenis kelamin, status ekonomi dengan stunting (p<0.05). Mayoritas subjek pernah diberi ASI (98,2%) dan masih lanjut diberi ASI (84,8%). Sebanyak 63,5% subjek tidak memenuhi Minimum Diet Diversity (MDD), sementara 47% subjek tidak memenuhi Egg and/or Flesh Food Consumption (EFF). Masih terdapat 25,9% subjek yang tidak memenuhi Minimum Meal Frequency (MMF) dan sebagian besar subjek yaitu 79,1% tidak memenuhi Minimum Acceptable Diet (MAD). Subjek yang mengalami stunting lebih tinggi pada kelompok subjek dengan keragaman makanan yang kurang, frekuensi makan yang cukup, serta diet yang diterima tidak memenuhi MAD. Hasil uji hubungan yang dilakukan pada variabel praktik pemberian ASI dan MP-ASI tidak membuktikan adanya hubungan signifikan dengan stunting (p>0,05)., This study aims to analyze the correlation between breastfeeding and complementary feeding practices with stunting among children aged 6–23 months in Kupang District. The design of this study was cross sectional study with 1404 subjects selected by purposive sampling. This study used secondary data from the Better Investment for Stunting Alleviation (BISA) research 2020. About 17.9% of the subjects were classified as severe stunting and 19.6% of the subjects were classified as stunting. The results of correlation test showed that there was a significant relationship between age, gender, and economic status with stunting (p<0.05). The majority of the subjects had been breastfed (98.2%) and continued to be breastfed (84.8%). About 63.5% of the subjects did not meet the Minimum Diet Diversity (MDD), while 47% of the subjects did not meet the Egg and/or Flesh Food Consumption (EFF). About 25.9% of the subjects did not meet the Minimum Meal Frequency (MMF) and most of the subjects about 79.1% did not meet the Minimum Acceptable Diet (MAD). Stunting subjects were higher in the subject group with less food diversity, sufficient eating frequency, and the diet received did not meet MAD. The results of correlation test conducted on the practice of breastfeeding and complementary feeding did not prove a significant relationship with stunting (p>0.05).

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.
