Judul: The Effect of Economic Pressure and Husband-Wife Interaction on Husband's Marriage Satisfaction
Abstrak: Penyebab perceraian tertinggi di Indonesia tahun 2021 adalah pertengkaran terus-menerus dan masalah ekonomi. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik, tekanan ekonomi, dan interaksi suami-istri terhadap kepuasan perkawinan suami. Responden terdiri dari 33 suami pekerja informal dan 32 suami pekerja formal di Jawa Barat yang diperoleh melalui teknik purposive sampling. Hasil uji beda menunjukkan lama pendidikan suami dan istri serta tekanan ekonomi pada kelompok informal berbeda signfikan dengan kelompok formal. Hasil uji hubungan menunjukkan semakin tidak stabil (informal) pekerjaan suami serta semakin rendah pendidikan suami dan istri, berhubungan dengan semakin tingginya tekanan ekonomi. Selain itu, semakin rendah tekanan ekonomi dan semakin baik interaksi suami-istri, berhubungan dengan semakin tingginya kepuasan perkawinan. Berdasarkan uji regresi, usia istri dan lama menikah berpengaruh negatif signifikan terhadap kepuasan perkawinan, sedangkan besar keluarga tanggungan dan interaksi suami-istri berpengaruh positif signifikan terhadap kepuasan perkawinan suami., The highest causes of divorce in Indonesia in 2021 were constant arguing and economic problems.

The different test results showed that the length of education of husband and wife and the economic pressure in the informal group were significantly different from the formal group. The relationship test results showed that the more unstable (informal) the husband's work and the lower the education of the husband and wife, associated with the higher the economic pressure. In addition, the lower the economic pressure and the better the husband-wife interaction, associated with the higher the marital satisfaction. Based on the regression test, wife's age and length of marriage have a significant negative effect on marital satisfaction, while the size of the dependent family and husband-wife interaction have a significant positive effect on husband's marital satisfaction.

Abstrak: Selama pandemi Covid-19, perintah bekerja dan sekolah dari rumah menjadi persoalan bagi keluarga di Indonesia. Penyesuaian perkawinan dan kemitraan peran gender dalam rumah tangga harus terjalin dengan baik agar terciptanya kepuasan perkawinan sehingga tidak terjadi konflik di dalam keluarga. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi kepuasan perkawinan pada keluarga utuh selama pandemi Covid-19. Responden dalam penelitian ini adalah istri dari keluarga utuh yang memiliki anak serta berdomisili di Kota Bogor. Teknik penarikan contoh menggunakan metode non-probability purposive sampling dengan jumlah contoh sebanyak 128 orang. Data diolah menggunakan uji deskriptif dan inferensia serta uji regresi linear berganda yang menggunakan SPSS 25 dan Structural Equation Modelling (SEM) menggunakan SmartPLS 3.0. Hasil uji korelasi menunjukkan bahwa terdapat hubungan positif antara penyesuaian perkawinan, kemitraan peran gender, dan kepuasan perkawinan. Hasil uji regresi linear menunjukkan bahwa pendapatan suami memiliki pengaruh positif signifikan terhadap kepuasan perkawinan. Secara konsisten, hasil uji korelasi, hasil uji regresi linear, dan SEM menunjukkan bahwa penyesuaian perkawinan dan kemitraan peran gender berpengaruh positif signifikan terhadap kepuasan perkawinan. Terdapat pengaruh tidak langsung antara penyesuaian perkawinan dan kepuasan perkawinan dengan mediator kemitraan peran gender., During the Covid-19 pandemic, orders to work and school from home have become a problem for whole families in Indonesia. Marital adjustment and gender role partnerships in the household must be well established in order to create marital satisfaction so that there is no conflict in the family. This study aims to analyze the factors that influence marital satisfaction in intact families during the Covid-19 pandemic. Respondents in this study are wives from intact families who have children and are domiciled in the city of Bogor. The sampling technique used method non-probability purposive sampling with the number of samples as many as 128 people. The data were processed using descriptive and inferential tests as well as multiple linear regression using SPSS 25 and Structural Equation Modeling (SEM) using SmartPLS 3.0. The results of the correlation test showed that there is a positive correlation between marital adjustment, gender role partnerships, and marital satisfaction. The results of the linear regression test showed that husband's income had a significant positive effect on marital satisfaction.

Judul: Apatite Growth Optimation on Chicken Mucouse by Fourier Transform Infrared (FTIR) Characterization
Abstrak: Some experiment had been conducted to grow apatite from supersaturated solution of calcium phosphate ions on chicken mucouse. The calcium and phosphate ions were originated from Ca(NO3)2 and (NH4)2HPO4. Carbonate ions from (NH4)2CO3 was also used as starting solution. Experiment was carried out within about 5 hours at temperature 370 C and pH 7. Value of Ca+ : PO4 3- was 1.67, while molar ratio of CO3 2- : PO4 3- was 0.5 : 1. Molarity of molar ratio CO3 2- : PO4 3- variated approximately 0.15 : 0.30, 0.51 : 1.02, and 0.90 : 1.80. Mass of mucouse powder was constant 0.75 gram. The analysis result of Fourier Transform Infrared (FTIR) showed that the precipitation was apatite carbonate type A and B. In these experiment it was found out that the mucouse reduce the crystallinity of apatite precipitant, and the growth of apatite crystal was optimum at solution with molar ratio CO3 2- : PO4 3- about 0.15 : 0.30.
