Abstrak: The objectives of this research are, first, to analyze the dynamics and self reliance of the community forest farmer groups of the Lemahduhur Village, Caringin Sub- District, Bogor; second, to identify the factors that affect to the dynamic and self reliance of the farmer groups; and the last, third, to explore the sustainability of the said forest farmer groups. Research was conducted on March-May 2011. Two farmer groups were studied through qualitative approach i.e the ‘Bina Mandiri’ and the ‘Puspa Mandiri’. The results show that the dynamic and self-reliance of the both groups are categorized as low.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
