Judul: The Quality of Husband and Wife Interaction of Post-Tsunami Selat Sunda Disaster Victims’ Family in Banten
Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh frekuensi interaksi, tingkat keterlibatan interaksi, potensi konflik (kesenjangan) dalam perkawinan terhadap kepuasan interaksi suami istri pada keluarga korban pascabencana tsunami di Banten. Penelitian ini merupakan bagian dari penelitian payung yang berjudul “Dampak Gempa Selat Sunda 2018 terhadap Kerentanan Sosial Ekonomi Keluarga dan Pencapaian SDGs Kesejahteraan” menggunakan metode cross sectional study. Penelitian melibatkan 61 keluarga yang tinggal di Desa Teluk yang dipilih berdasarkan Data RKI (Riset Kolaborasi Indonesia) 2020. Sebagian besar keluarga merupakan keluarga dengan tahapan perkembangan usia anak dewasa. Hasil uji hubungan menunjukkan bahwa semakin lama usia pernikahan, maka semakin menurun frekuensi interaksi suami istri. Uji regresi menunjukkan bahwa semakin bertambahnya tahapan perkembangan akan menurunkan kepuasan interaksi. Tingkat keterlibatan interaksi yang tinggi akan meningkatkan kepuasan interaksi yang dirasakan istri sedangkan potensi konflik (kesenjangan) dalam perkawinan yang tinggi akan menurunkan kepuasan interaksi., This study aims to analyze the influence of frequency of interaction, level of interaction involvement, potential conflict (gap) in marriage to the satisfaction of husband-wife interaction of post-tsunami victims' families in Banten. This research is part of an umbrella study entitled "Dampak Gempa Selat Sunda 2018 terhadap Kerentanan Sosial Ekonomi Keluarga dan Pencapaian SDGs Kesejahteraan" using a cross sectional study method. The study involved 61 families living in Teluk Village which were selected based on the Data RKI (Riset Kolaborasi Indonesia) 2020. Most families are families with the developmental stages of adult children. The results of the relationship test show that the longer age of marriage, the lower the frequency of husband and wife interactions. Regression test shows that the increasing stages of development will decrease satisfaction of interaction. A high level of interaction involvement will increase the satisfaction of interaction felt by the wife, while a high potential conflict (gap) in marriage will satisfaction of interaction.

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: The Exploration of Discrete Logarithm over Finite Field GF(3m)
Abstrak: The security of many public~key algorithms is based on the problem of finding discrete logarithms. The generalized discrete logarithm problem is the following: given a finite cyclic group G of order n, a generator a of G, and an element fl E G, find the integer x, 0 ~ x ~ n - 1, such that 0: = fl. Algorithm for discrete logarithm problem focused on Menezes et al. (1997) that consist of exhaustive search algorithm, the baby-step giant-step algorithm, Pollard's rho algorithm, Pohlig-Hellman algorithm, and index-calculus algorithm. These algorithms are explorated to be used in discrete logarithm problem over finite field GF(3m ). The exploration also produces some algorithms, i.e. naif negative algorithm, baby-step mother-step algorithm, baby-step mother free-step algorithm, and baby-step free-step algorithm. All algorithms implemented using Maple 11. The Pohlig-Hellman and baby-step giant-step algorithms are efficient enough to be used in discrete logarithm problem over finite field GF(3m ) for m < 20.
