Abstrak: This study aims to examine the pattern and characteristics of agricultural land convertion and its factor and the rate of agricultural land conversion in Kediri Regency. Descriptive analysis method used to analyze the patterns, characteristics and the rate of land conversion. Meanwhile, to analyze the factors used multiple linear regression models. The results showed that the patterns and characteristics of land conversion in Kediri Regency spontaneously still very little compared by the plan. The government managed to overcome the problem of agricultural land deficit through by extensification farmland program. Empirically the factors that influence agricultural land convertion in the real level of the farmer in Ngasem Subdistrict the first is the number of dependents, which is indicating the rapid growth of the region after opening area. The second is the distance of the area from the center of he central business district. Third is the price of agricultural land per/ square meter. The fourth is land held previously. The implication of this is that local government needs to coordinate with the owners of wide land so the conversion can be controlled.

Judul: Analisis dampak alih fungsi lahan pertanian terhadap kemandirian pangan di Kabipaten Subang (studi kasus : Desa Belendung, Kecamatan Cibogo)
Abstrak: Increasing of population and economy growth in Indonesia, particularly in industrial sector, leads to the demand increasing of land.

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.
