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: Vulnerability and Community Resilience in Facing Landslide Disaster (Case: Kampung Muara 1, Cibunian Village, Pamijahan District, Bogor Regency, West Java)
Abstrak: Bencana tanah longsor merupakan suatu peristiwa alam yang dapat menyebabkan kerugian di berbagai aspek bagi komunitas yang terdampak. Dampak kerugian dari terjadinya bencana tersebut memungkinkan adanya perubahan pada tingkat kerentanan dari suatu komunitas. Salah satu cara menanggulangi kerentanan komunitas tersebut adalah dengan meningkatkan kapasitas adaptif yang dimiliki oleh komunitas terdampak sehingga komunitas akan lebih mudah dalam mencapai tahap resiliensi. Penelitian ini memiliki tujuan untuk menganalisis tingkatan dan hubungan antara kerentanan dan resiliensi komunitas dalam menghadapi bencana tanah longsor. Pendekatan yang dilakukan pada penelitian ini adalah pendekatan kuantitatif dengan metode survei kepada 80 orang responden, kemudian didukung dengan pendekatan kualitatif yang menggunakan metode wawancara mendalam. Hasil penelitian menunjukkan bahwa tingkat kerentanan dan tingkat resiliensi dari komunitas Kampung Muara 1 tergolong sedang, serta terdapat hubungan antara tingkat kerentanan dan tingkat resiliensi komunitas tersebut., A landslide disaster is a natural event that can cause losses in various aspects for the affected community. The impact of losses from these disasters allows for changes in the level of vulnerability of a community. One way to overcome community vulnerability is to increase the adaptive capacity of affected communities so that it will be easier for the community to reach the resilience stage. This research aims to analyze the level and relationship between community vulnerability and resilience in facing landslide disasters. The approach taken in this research was a quantitative approach using a survey method for 80 respondents, then supported by a qualitative approach using in-depth interview methods. The research results show that the level of vulnerability and level of resilience of the Muara 1 Village community is classified as moderate, and there is a relationship between the level of vulnerability and the level of resilience of the community.

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.
