Judul: Kelentingan Nafkah Masyarakat Desa Di Kawasan Banjir (Kasus:Daerah Aliran Sungai Cibeet, Desa Karangligar,Kecamatan Telukjambe Barat, Kabupaten Karawang)
Abstrak: Bencana alam layaknya banjir tidak dapat duga datangnya, para petani yang menggatungkan hidupnya terhadap pertanian harus berjuang keras untuk bertahan dari banjir, petani tidak bisa lagi menggantungkan hidupnya dengan modal alam saja namun mulai menggunakan modal sosial, modal finansial, modal fisik dan modal manusia. Petani yang terkena banjir mengalami kerentanan nafkah akibat banjir. Pemanfaatan dari kelima buah modal akan mempengaruhi sebrapa parah kerentananan yang diakibatkan oleh banjirdiduga terdapat pengaruh antara modal nafkah dengan tingkat kerentanan rumahtangga (Livelihood Vulnerability Index). Modal nafkah yang diukur berupa modal manusia, modal sosial, modal alam, modal fisik dan modal finansial, sedangkan tingkat kerentanan diukur denganexposure, sensitivity, dan adaptice capacity. Hasil dari penelitian menunjukan bahwa terdapat pengaruh antara modal alam, modal finansial, dan modalmanusia di daerah banjir sedangkan pada daerahnon banjir modal nafkah yang berpengaruh adalah modal alam, modal manusia dan modal fisik

Judul: Strategi Penghidupan dan Resiliensi Nafkah Rumah Tangga Petani di Kawasan Banjir (Kasus: Desa Sumber Urip, Kecamatan Pebayuran, Kabupaten Bekasi Utara)
Abstrak: Rumah tangga petani di kawasan banjir mengalami kerugian dan terhambat pendapatannya yang disebabkan terendamnya lahan pertanian oleh banjir yang menyebabkan kerentanan pada sistem nafkah. Rumah tangga melakukan berbagai strategi nafkah serta memanfaatkan sumber-sumber nafkah yang tersedia agar dapat bertahan dan segera pulih dari krisis. Tujuan dari penelitian ini adalah untuk menganalisis struktur nafkah, strategi nafkah dan faktor-faktor yang mempengaruhi tercapainya resiliensi nafkah rumah tangga petani di kawasan banjir, Desa Sumber Urip, Kecamatan Pebayuran. Penelitian ini merupakan penelitian kuantitatif yang didukung dengan kualitatif. Teknik pengumpulan data melalui kuesioner untuk data kuantitatif dan wawancara mendalam untuk data kualitatif. Hasil penelitian ini menunjukan bahwa faktor yang mempengaruhi resiliensi rumah tangga petani di kawasan banjir adalah persentase pendapatan pertanian sawah terhadap total pendapatan rumah tangga, jumlah sumber pendapatan rumah tangga, jumlah organisasi/lembaga yang diikuti rumah tangga, dan jumlah kegagalan menghadapi krisis., Farmer households in flooded areas suffer losses and have reduced income as a result of agricultural land flooding, which exposes the livelihood system to vulnerability. Households use various adaptation mechanisms and take advantage of available sources of income to survive and recover quickly from the crisis. The purpose of this study is to analyze the structure of income, livelihood strategies , and factors that support the achievement of household livelihood resilience among farmers in flooded areas, Sumber Urip Village, Pebayuran District. This is a quantitative study that is supported by qualitative data. Technique of collecting data is through questionnaires for quantitative and in-depth interviews for qualitative. The results of this study indicate that the percentage of rice farming income to total household income, the number of sources of household income, the number of organizations/institutions in which households participate, and the number of failures to face the crisis are the factors that influence the resilience of farmer households in flooded areas.

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.
