Judul: Objective Economic Pressure, Livelihood Strategies, and Subjective-Economic Welfare of Families of Victims of The Post-Sunda Strait Tsunami in Banten
Abstrak: Penelitian ini merupakan bagian dari penelitian payung berjudul “Dampak Tsunami Selat Sunda 2018 terhadap Kerentanan Sosial Ekonomi Keluarga dan Pencapaian SDGs Kesejahteraan”. Penelitian ini bertujuan untuk menganalisis karakteristik keluarga, tekanan ekonomi objektif, strategi nafkah, dan kesejahteraan subjektif-ekonomi bagi korban bencana Tsunami Selat Sunda di Banten. Metode penelitian yang digunakan adalah cross sectional study yang melibatkan 60 contoh yang dipilih secara simple random sampling. Pengumpulan data dilakukan pada bulan Maret 2021. Analisis data menggunakan uji deskriptif, uji korelasi, dan uji regresi logistik. Hasil uji regresi menunjukkan bahwa usia istri, usia suami, pendapatan per kapita, dan tekanan ekonomi objektif berpengaruh signifikan terhadap kesejahteraan subjektif-ekonomi. Berdasarkan nilai peluang kumulatif dari 60 responden diketahui peluang meningkatkan kesejahteraan subjektif-ekonomi keluarga pada kategori rendah adalah 0,989 kali dan peluang untuk kategori tinggi berdasarkan nilai odds ratio adalah 6,632 kali lebih tinggi dari kategori lainnya. Perpindahan tempat tinggal dari daerah pesisir ke hunian tetap di tengah perkebunan tidak membuat keluarga mengubah mata pencaharian atau mendalami keterampilan baru dalam mencari nafkah untuk meningkatkan pendapatan.

Judul: The Influence of Family Functions on Subjective Welfare of Families of Victims of the Post-Tsunami Disaster in Banten
Abstrak: Penelitian ini merupakan bagian dari penelitian payung yang berjudul “Dampak Gempa Selat Sunda 2018 Terhadap Kerentanan Sosial Ekonomi Keluarga dan Pencapaian SDGs Kesejahteraan”. Penelitian ini bertujuan untuk mengetahui pengaruh keberfungsian keluarga terhadap kesejahteraan subjektif keluarga korban pascabencana tsunami di Banten. Penelitian ini menggunakan metode cross sectional study dengan melibatkan 60 keluarga contoh yang dipilih berdasarkan metode simple random sampling. Hasil penelitian menunjukkan secara keseluruhan lebih dari separuh keluarga contoh pascabencana mengalami peningkatan fungsi keluarga dan kesejahteraan subjektif keluarga dengan terkategori cukup. Berdasarkan analisis korelasi, pendapatan total dan pendapatan per kapita keluarga berhubungan negatif signifikan dengan fungsi kontribusi dan perlindungan pada keberfungsian keluarga sedangkan besar keluarga berhubungan negatif signifikan dengan fungsi instrumental pada keberfungsian keluarga. Hasil uji regresi menunjukkan keberfungsian keluarga signifikan berpengaruh positif terhadap kesejahteraan subjektif keluarga. Dimensi fungsi ekspresif, fungsi pemeliharaan sistem, fungsi instrumental, serta fungsi kontribusi dan perlindungan berpengaruh positif terhadap kesejahteraan subjektif keluarga. Karakteristik keluarga meliputi usia istri, usia anak terkecil, lama pendidikan istri, lama menikah, pendapatan per kapita, dan status kemiskinan berpengaruh positif terhadap kesejahteraan subjektif keluarga. Berkah komunikasi dan ikatan kebersamaan serta dukungan sosial tinggi keluarga merasakan kepuasan tinggi secara psikologis dan secara sosial walaupun perekonomian mereka tergolong cukup untuk kebutuhan sehari-hari saja., This research is part of an umbrella study entitled "The Impact of the 2018 Sunda Strait Earthquake on Family Socio-Economic Vulnerability and Achievement of Welfare SDGs". This study aims to determine the effect of family functioning on the subjective welfare of families of victims of the post-tsunami disaster in Banten. This study used a cross sectional study method involving 60 sample families selected based on the simple random sampling method. The results, over all more than half of the post-disaster sample families experienced an increase in family function and family subjective well-being, categorized as moderate. Based on correlation analysis, total income and family income per capita were significantly negatively related to contribution and protection functions on family functioning, while family size was significantly negatively related to instrumental functions on family functioning. The results of the regression test, family functioning had a significant positive effect on the subjective well-being of the family. The dimensions of expressive function, system maintenance function, instrumental function, and contribution and protection functions have a positive effect on the subjective welfare of the family. Family characteristics include wife's age, age of the youngest child, wife's length of education, length of marriage, income per capita, and poverty status have a positive effect on the subjective welfare of the family. The blessing of communication and ties of togetherness and high social support, the family feels high psychologically and socially, even though their economy is quite sufficient for their daily needs.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
