Judul: The Effect of Economic Pressure and Family Resilience on Parenting Baduta Children During the Covid-19 Pandemic
Abstrak: Pandemi covi-19 memicu timbul berbagai masalah baru dalam keluarga yang berdampak pada pola asuh anak baduta. Penelitian ini bertujuan untuk menganalisis pengaruh tekanan ekonomi dan ketahanan keluarga terhadap pola asuh anak baduta pada masa pandemi covid-19. Pengambilan contoh dilakukan secara purposive sampling pada yang memiliki anak baduta dengan responden sebanyak 30 orang. Lokasi penelitian di Desa Cibatok 2, kecamatan Cibungbulang, Kabupaten Bogor, Jawa Barat menggunakan desain penelitian cross sectional study. Uji korelasi menunjukkan bahwa usia menikah istri, pendapatan per kapita dan ketahanan keluarga berhubungan positif signifikan dengan pola asuh serta pendapatan dengan ketahanan keluarga. Besar keluarga berhubungan negatif signifikan dengan ketahanan keluarga dan pola asuh. Uji regresi menunjukkan bahwa usia menikah istri, lama pendidikan istri, pendapatan per kapita dan ketahanan keluarga berpengaruh positif signifikan terhadap pola asuh, sedangakan besar keluarga dan ketahanan keluarga berpengaruh negatif signifikan terhadap pola asuh. Kata kunci : Baduta, Covid-19, Tekanan ekonomi, Ketahanan keluarga, Pola asuh., The COVID-19 pandemic has triggered new problems in the family that have an impact on the quality of the childcare environment. clown. This study aims to analyze the effect of economic pressure and family resilience on the parenting pattern of children under the age of two during the COVID-19 pandemic. Sampling was done by purposive sampling on those who have children under the age of 30 with 30 respondents. The research location is in Cibatok 2 Village, Cibungbulang sub-district, Bogor Regency, West Java using a cross-sectional study design. Correlation test shows that wife's age at marriage, income per capita and family resilience have a significant positive relationship with parenting and income with family resilience. Family size is significantly negatively related to family resilience and parenting patterns. The regression test showed that the wife's married age, wife's length of education, income per capita and family resilience had a significant positive effect on parenting, while family size and family resilience had a significant negative effect on parenting.

Judul: The Influence of Economic Pressure and Gender Role to Family Resilience During the Covid-19 Pandemic
Abstrak: Adanya Covid-19 merubah tatanan kehidupan sosial ekonomi masyarakat. Keluarga harus mampu menjalankan peran gender dan mempertahankan ketahanan keluarga. Penelitian ini bertujuan menganalisis pengaruh karakteristik keluarga, tekanan ekonomi, dan peran gender terhadap ketahanan keluarga selama masa pandemi Covid-19. Responden pada penelitian ini adalah istri dari keluarga utuh yang memiliki anak yang tersebar di Kabupaten Bogor. Teknik penarikan contoh menggunakan metode purposive sampling dengan jumlah contoh sebanyak 84 orang. Data dikumpulkan melalui kuesioner online menggunakan google form. Data diolah menggunakan uji deskriptif dan uji regresi linier berganda. Hasil penelitian menemukan sebagian besar tekanan ekonomi keluarga berada pada kategori rendah. Sebagian variabel peran gender berada pada kategori rendah. Namun, sebagian besar ketahanan keluarga berada pada kategori tinggi. Uji hubungan karakteristik responden menunjukkan terdapat hubungan signifikan negatif antara umur suami, lama menikah, tekanan ekonomi subjektif, dan tekanan ekonomi total dengan ketahanan keluarga. Selain itu, pendidikan suami-istri, pendapatan suami, kemitraan gender dan peran gender berhubungan signifikan positif dengan ketahanan keluarga. Hasil analisis uji regresi linier berganda menunjukkan terdapat pengaruh yang signifikan negatif antara tekanan ekonomi dengan ketahanan keluarga dan pengaruh signifikan positif pada peran gender dan pendapatan suami. Hal ini berarti semakin rendah tekanan ekonomi yang dihadapi oleh keluarga maka semakin tinggi ketahanan keluarga yang dimiliki dan semakin tinggi peran gender serta pendapatan suami maka ketahanan keluarga akan semakin baik., The existence of Covid-19 has changed the social and economic life of society. Families must be able to carry out gender roles and maintain family resilience. This study aims to analyze the effect of family characteristics, economic pressure, and gender roles on family resilience during the Covid-19 pandemic. Respondents in this study were wives from intact families with children scattered in Bogor Regency. The sampling technique used purposive sampling method with the number of samples as many as 84 people. Data was collected through an online questionnaire using a google form. The data were processed using descriptive tests and multiple linear regression tests. The results of the study found that most of the family's economic pressure was in the low category. Some of the gender role variables are in the low category. However, most of the family resilience is in the high category. The relationship test of respondents' characteristics showed that there was a significant negative relationship between husband's age, length of marriage, subjective economic pressure, and total economic pressure with family resilience. In addition, husband and wife's education, husband's income, gender partnership and gender roles are significantly positively related to family resilience. The results of multiple linear regression analysis showed that there was a significant negative effect between economic pressure and family resilience and a significant positive effect on gender roles and husband's income. This means that the lower the economic pressure faced by the family, the higher the family's resilience and the higher the gender role and husband's income, the better the family's resilience.

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.
