Judul: Faktor – Faktor yang Mempengaruhi Pendapatan Total Petani Hutan Rakyat di Desa Karyasari, Kecamatan Leuwiliang, Kabupaten Bogor
Abstrak: The development of community forest is related to farmers prosperity. The total income of community forest farmers can be an indicator of their prosperity. Therefore, the purpose of this research to analyze factors which influence the incomes of community forest farmers at Karyasari Village, Leuwiliang Sub- District, Bogor District.

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.
