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: Social Capital and Household Participation in  Community Collective Action Facing Landslide Disaster (Case: Kampung Muara 1, Cibunian Village, Pamijahan District, Bogor Regency, West Java)
Abstrak: Bencana alam yang terjadi di Indonesia menimbulkan banyak dampak, baik kehilangan materi maupun jiwa manusia. Modal sosial dapat menjadi strategi dalam mencapai resiliensi komunitas apabila disertai dengan aksi kolektif dari komunitas itu sendiri. Partisipasi komunitas dalam setiap aksi kolektif komunitas menghadapi bencana sangat diperlukan. Tujuan penelitian ini untuk menganalisis modal sosial dan partisipasi rumah tangga dalam aksi kolektif komunitas menghadapi bencana tanah longsor. Pengumpulan data melalui kuesioner pada 80 orang responden dan wawancara mandalam. Pengolahan data menggunakan uji korelasi rank spearman. Hasil penelitian menunjukkan bahwa meskipun modal sosial tergolong tinggi, namun hubungan modal sosial dan partisipasi rumah tangga dalam aksi kolektif komunitas tergolong lemah., The natural disasters that occurred in Indonesia caused many impacts, both loss of material and human lives. Social capital can be a strategy for achieving community resilience if accompanied by collective action from the community itself. Community participation in every community collective action facing disasters is very necessary. The aim of this research is to analyze social capital and household participation in collective community action in facing landslide. Data was collected through questionnaires from 80 respondents and in-depth interviews. Data processing uses the spearman rank correlation test. The results of the study show that although social capital is relatively high, the relationship between social capital and household participation in community collective action is relatively weak.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
