Judul: Process and Output of Family Resilience on  Lebak Flash Flood Victims in 2020 Who Stay in Temporary Housing
Abstrak: Penelitian ini bertujuan untuk menganalisis proses dan output resiliensi keluarga korban banjir bandang. Desain penelitian adalah cross sectional study. Pendekatan retrospektif digunakan untuk mendapatkan data 1 bulan pascabencana. Sampel dipilih secara purposive sampling yakni 60 keluarga korban banjir bandang Lebak yang tinggal di hunian sementara Desa Bungur Mekar dan Desa Pajagan. Pengambilan data dilakukan pada Maret 2021, tepat 15 bulan pascabencana. Hasil penelitian menunjukkan bahwa bencana menyebabkan keluarga mengalami krisis selama 3,5 bulan. Proses resiliensi keluarga pada 15 bulan lebih tinggi dibandingkan pada 1 bulan pascabencana. Seluruh variabel pada proses dan output resiliensi keluarga saling berhubungan positif di setiap bulannya. Hasil uji regresi menunjukkan bahwa pada bulan ke-15, kapasitas organisasi keluarga dan atmosfer keluarga secara konsisten berpengaruh terhadap kenaikan capaian output resiliensi keluarga (subjektif). Sementara itu, semakin bertambah tua usia suami berpengaruh terhadap penurunan capaian output resiliensi keluarga (subjektif). Hasil penelitian diharapkan menyediakan data dan informasi bagi para pengambil kebijakan dan program untuk meningkatkan ketangguhan keluarga dalam menghadapi bencana., The study aimed to analyze the process and the output of family resilience on flash flood victims. The research design was cross sectional study. Retrospective approach used to obtain data for the 1 st month post-disaster. The sample was selected by purposive sampling, specifically 60 families of Lebak flash flood victims who stay in temporary housing Bungur Mekar Village and Pajagan Village. Data was collected in March 2021, 15th months post-disaster. The result showed that the disaster caused the family to live in crisis for 3,5 months. The process of family resilience at 15th months is higher than at 1st month post-disaster. All process variables and the output of family resilience were positively related every month. The regression test results showed that at the 15th months, family organization capacity and family atmosphere consistently influenced the increase of family resilience output (subjective). Meanwhile, the older husband’s age influenced the decrease of family resilience output (subjective). The result of this study are expected to provide data and information for policy and program makers to reinforce family resilience in dealing with disasters

Judul: Correlation between Social Capital and Family Resilience in Facing Floods (Case Study: Bojongkulur Village, Gunung Putri Sub-district, Bogor District, West Java)
Abstrak: Bencana banjir merupakan bencana yang kerap terjadi di negara Indonesia. BNPB (2021) mencatat bahwa bencana banjir mendominasi kejadian bencana alam Indonesia dengan jumlah 42,1%. Untuk menjadi masyarakat yang sigap akan bencana banjir, perlu dilakukan upaya dalam meningkatkan resiliensi keluarga. Modal sosial merupakan salah satu aspek yang penting dalam upaya meningkatkan resiliensi terhadap bencana banjir. Tujuan dari penulisan adalah untuk mendeskripsikan kondisi banjir dan perilaku masyarakat, menganalisis tingkat modal sosial dan resiliensi keluarga dalam menghadapi banjir yang dimiliki oleh keluarga di Desa Bojongkulur, serta hubungan antara modal sosial dengan tingkat resiliensi keluarga dalam menghadapi bencana banjir di Desa Bojongkulur. Metode yang digunakan dalam penelitian ini adalah pendekatan kuantitatif yang didukung pendekatan kualitatif. Data kuantitatif yang diperoleh akan diolah dan diuji menggunakan statistik uji rank spearman. Data kualitatif yang diperoleh melalui wawancara mendalam terhadap informan akan disajikan secara deskriptif. Hasil penelitian menunjukkan bahwa tingkat modal sosial dan resiliensi keluarga yang dimiliki masyarakat Desa Bojongkulur berada pada kategori tinggi dan terdapat hubungan yang signifikan dan positif antara tingkat modal sosial dengan tingkat resiliensi keluarga., Floods are a disaster that often hits Indonesia. It was stated by BNPB (2021) that floods dominates Indonesia’s total natural disaster incident, with a total of 42,1% of total incident. High rainfall that water catchment areas can not hold is a common cause of floods. In order to make a disaster alert community, family resiliency increasement is necessary. Social capital is one of the most important aspect in dealing with floods. The purpose of this paper is to describe the floods and community action in dealing with that disaster, analyzing social capital and resilience level which Bojongkulur Village has in order to face floods, and the correlation between them. The method used in this study is quantitative approach supported by qualitative approach. The obtained quantitative data will be processed and tested with spearman’s correlation test. Meanwhile, qualitative data obtained from informan by depth interview will be presented descriptively. The results shows that social capital and family resilience have high level and there’s a significant and positive correlation between social capital level and family resilience level.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
