Judul: Analisis jalur faktor-faktor yang mempengaruhi ketahanan pangan rumahtangga di Kabupaten Lebak, Provinsi Banten
Abstrak: The objective of this research were to: 1) identificate household socio economic characteristics and food acses, 2) analyze household consumption level and household food security level, 3) analyze relation of socio economic factors and household food security, 4) analyze impact of direct factors and indirect factors to household food security. This research was conducted by using cross sectional design. The location was in Pasindangan and Banjarsari Village, Cileles and Warunggunung Subdistrict, Lebak Distric that chosen purposively with concideration that farmer's household. The sample were 101 househholds. The result of the research shows that almost all (62.4%) household were household food security, household food insecurity in heavy level (7%), household food insecurity in moderate level (5%), and household food insecure (26%). factors that significantly relation with household food security were size of household, own of land, and household expenditure per capita. Direct factor that influence household food security was household expenditure expenditure per capita. Indirect factors that influence household food security were size of household – household expenditure per capita – household food security.

Judul: Analisis pengaruh food coping strategy terhadap ketahanan pangan rumahtangga petani di kabupaten Lebak Banten
Abstrak: The general objective of this research was to analyze the influence of score of food coping strategy toward household food security. The particular objectives of this research were to: 1) Identify household food security; 2) identify the characteristics food access of sample (size of family, father’s education, father’s occupation, family’s income, education and nutritional knowledge of the mothers, and social support); 3) Identify the food coping strategy in farmer’s household; 4) Identify the person who do the food coping strategy in farmer’s household; 5) Analyze the correlation between score of food coping strategy and household food security; 6) Analyze the influence factors of household food security. The research was conducted by using cross sectional study design from April to May 2009 in Kabupaten Lebak Banten. Sample was chosen by purposive sampling resulting in 101 households. The results show that 63.4% samples in household’s level were in food secure condition and 25.7% samples were in serious food insecure condition. Half of samples (49.5%) included in the small households (with 4 members of household or less). Generally, in age, most of the paterfamilias (57.4%) were in medium adult category (40 – 59 years). The dissemination of mother’s age were in the early adult category, that is 46.5% and 47.5% of mothers were in the medium adult category. Almost of all the mother (87.1%) included in low nutritional knowledge group. Spearman Correlation Test shows that the score of coping strategy have no significant correlation with household food security and the size of household has negative significant correlation with household food security (r=-0.270; p<0.01). The number of farm areas that owned by the farmer’s households have positive significant correlation with their household food security (r=0.309; p<0.01). It means that larger farm area that owned by the farmer’s household implied the better condition of household food security. However, Pearson Correlation Test shows that consumption of energy has negative significant correlation with score of coping strategy (r=-0.208; p=<0.05). It means that the higher score of coping strategy implied little in consumption of energy. It shows the decrease of food security condition. Regretion Test shows the factors that influence the household food security, for instance, number of farm area that owned by farmer household, poverty status, size of household, score of coping strategy, and alocation of food expenditure.

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.
