Judul: Stress, Social Support, and Subjective Well-Being of Single Father Families During The Covid-19 Pandemic
Abstrak: Ayah tunggal kadangkala merasakan stres sehingga memerlukan dukungan sosial. Stres dan dukungan sosial akan memengaruhi kesejahteraan subjektif. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik keluarga, stres, dan dukungan sosial terhadap kesejahteraan subjektif pada keluarga ayah tunggal selama pandemi Covid-19. Penelitian ini menggunakan metode penelitian kuantitatif dengan desain cross sectional study yang melibatkan 60 ayah tunggal yang dipilih secara purposive sampling. Hasil penelitian menemukan bahwa lebih dari separuh ayah tunggal kadang-kadang merasa gelisah, stres, ataupun kesal dalam rentang waktu sebulan terakhir. Lebih dari separuh ayah tunggal memiliki dukungan sosial rendah, sedangkan sebagian besar ayah tunggal memiliki kesejahteraan subjektif sedang. Uji korelasi menunjukkan bahwa terdapat hubungan negatif signifikan antara pendapatan per kapita dengan stres dan stres dengan kesejahteraan subjektif, sedangkan pendapatan per kapita dan dukungan sosial berhubungan positif signifikan dengan kesejahteraan subjektif. Uji regresi menunjukkan bahwa pendapatan per kapita dan dukungan sosial berpengaruh positif signifikan terhadap kesejahteraan subjektif, sedangkan stres berpengaruh negatif signifikan terhadap kesejahteraan subjektif., Single fathers sometimes feel stressed and need social support. Stress and social support will affect subjective well-being. This study aims to analyze the influence of family characteristics, stress, and social support on subjective wellbeing of single father families during the Covid-19 pandemic. The research used quantitative research method with cross sectional study design involving 60 single fathers selected by purposive sampling. The results found that more than most single fathers sometimes felt nervous, stressed, or annoyed in the past month. More than most single fathers have a low social support, while most single fathers have a moderate subjective well-being. Correlation test shows that there is a significant negative relationship between per capita income with stress and stress with subjective well-being, while per capita income and social support has a significant positive relationship with subjective well-being. Regression tests show that per capita income and social support has a significant positive effect on subjective wellbeing, while stress has a significant negative effect on subjective well-being.

Judul: Economic Pressures, Coping Strategies, and  Quality of Life of Single Father Families during The Covid-19 Pandemic.
Abstrak: Keluarga ayah tunggal rentan dengan permasalahan ekonomi di masa pandemi Covid-19. Strategi koping dibutuhkan sebagai upaya untuk meningkatkan kualitas hidupnya. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik keluarga, tekanan ekonomi, dan strategi koping terhadap kualitas hidup pada keluarga ayah tunggal selama pandemi Covid-19. Penelitian ini menggunakan metode penelitian kuantitatif dengan desain cross sectional study yang melibatkan 60 ayah tunggal yang dipilih secara purposive sampling. Hasil penelitian menemukan bahwa hampir dari separuh ayah tunggal memiliki tekanan ekonomi objektif dan subjektif sedang, sebagian besar ayah tunggal memiliki strategi koping rendah, sedangkan hampir separuh ayah tunggal memiliki kualitas hidup sedang. Uji korelasi menunjukkan bahwa tekanan ekonomi objektif dan subjektif berhubungan negatif dengan kualitas hidup, sedangkan pendapatan per kapita dan strategi koping berhubungan positif dengan kualitas hidup. Uji regresi menunjukkan bahwa tekanan ekonomi subjektif berpengaruh negatif terhadap kualitas hidup, sedangkan strategi koping berpengaruh positif terhadap kualitas hidup., Single father families are vulnerable to economic problems during the Covid 19 pandemic. Coping strategies are needed to improve their quality of life. This study aims to analyze the influence of family characteristics, economic pressures, and coping strategies on the quality of life of single father families during the Covid-19 pandemic. The research used a quantitative research method with a cross-sectional study design involving 60 single fathers selected by purposive sampling. The results found that almost half of single fathers had moderate economic pressures, almost all single fathers had low coping strategies, and almost half of single fathers had moderate quality of life. Correlation test showed that objective and subjective economic pressures are negatively related to the quality of life, while per capita income and coping strategies are positively related to quality of life. Regression test showed that subjective economic pressure had a negative effect on the quality of life while coping strategies had a positive effect on the quality of life.

Judul: Synthesis of Molybdenum Trioxide (MoO3) by Electrochemical Method for Electrochromics Application
Abstrak: Molybdenum trioxide (MoO3) thin films have been deposited on glass substrates by electrochemical method using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O). The films were deposited onto glass substrates as the control temperature at 25○C and annealing treatment at 350○C for 30 mins. The MoO3 thin films were investigated by UV-Vis, X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM). The JCPDS card show that orthorhombic MoO3 (α- phase) has been formed. Molybdenum trioxide MoO3 formation was also confirmed by JCPDS card no. 35-0609. The SEM photographs revealed that the spherical and rod-like morphology and their grains size increased with increasing of heating temperatures. The measurement results show that the MoO3 thin film prepared at 350°C transmited about 80% of the visible spectrum. The effect of different heat treatments on surface morphology, thickness and optical properties of the films are discussed in this thesis.
