The population in this research are family farmers who have children 4 and 5 th grade who reside in the village Sindangjaya, District Cipanas, Cianjur with a sample of 35 children. Sampling was conducted using probability sampling method with random sampling techniques. The results showed that the internal susceptibility to family farmers is low, relatively low external vulnerability child, and child well-being on farm families is low. Typology vulnerability of children and the well-being of children in a family of farmers included in Type 1 and Type 4.

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.
