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: The Role of Collective Action for Disaster Mitigation in Community Resilience Facing Landslides
Abstrak: Bencana tanah longsor mengakibatkan berbagai dampak seperti rusaknya sarana dan prasarana, kehilangan tempat tinggal, hingga banyaknya korban jiwa sekaligus memberikan dampak psikologis yang memengaruhi kehidupan sosial masyarakat. Dampak negatif dari bencana dapat dikurangi dengan melakukan mitigasi agar komunitas bisa bertahan. Kampung Muara 1, Desa Cibunian telah melakukan kegiatan mitigasi baik struktural maupun non struktural. Aksi kolektif yang dilakukan komunitas dapat mencapai resiliensi jika komunitas melakukan tindakan kolektif. Metode penelitian menggunakan pendekatan kuantitatif melalui kuesioner dan pendekatan kualitatif dengan observasi serta wawancara mendalam. Responden dalam penelitian ini berjumlah 80 responden. Data kuantitatif diolah menggunakan aplikasi Microsoft Excel 365 dan aplikasi IBM SPSS Statistic 24. Penelitian ini menggunakan analisis statistik sederhana yang didukung data kualitatif untuk melihat variabel aksi kolektif dengan resiliensi komunitas dalam menghadapi bencana tanah longsor. Hasil penelitian menunjukkan bahwa aksi kolektif masih bersifat top down dan belum sepenuhnya komunitas Kampung Muara 1 dikatakan resilien.

Judul: Apatite Growth Optimation on Chicken Mucouse by Fourier Transform Infrared (FTIR) Characterization
Abstrak: Some experiment had been conducted to grow apatite from supersaturated solution of calcium phosphate ions on chicken mucouse. The calcium and phosphate ions were originated from Ca(NO3)2 and (NH4)2HPO4. Carbonate ions from (NH4)2CO3 was also used as starting solution. Experiment was carried out within about 5 hours at temperature 370 C and pH 7. Value of Ca+ : PO4 3- was 1.67, while molar ratio of CO3 2- : PO4 3- was 0.5 : 1. Molarity of molar ratio CO3 2- : PO4 3- variated approximately 0.15 : 0.30, 0.51 : 1.02, and 0.90 : 1.80. Mass of mucouse powder was constant 0.75 gram. The analysis result of Fourier Transform Infrared (FTIR) showed that the precipitation was apatite carbonate type A and B. In these experiment it was found out that the mucouse reduce the crystallinity of apatite precipitant, and the growth of apatite crystal was optimum at solution with molar ratio CO3 2- : PO4 3- about 0.15 : 0.30.
