Abstrak: Organic farming is agricultural activities that seek the use of outside intake and avoid the use of pesticides and synthetic fertilizer. The results showed that the organic farmers and conventional farmers have the high responses of organic farming. However, the characteristics of organic farmer have no relation with farmer’s respons of organic farming. Then, in conventional farmers, formal education and the courage to take the risks have relation with farmer’s respons of organic farming. This research also showed there are no relation between farmer’s respons of organic farming with farmer’s income. Nevertheless, can be predicted that there are chances of the conventional farmers to adopt the organic farming

Abstrak: The objectives of this study are to identify the implementation of organic farming, identify farmer’s perception about the characteristic of organic farming innovation, analyze the influence of farmer’s perception to their farming implementation, and also to analyze the influence of farmer’s characteristic to their perception about organic farming innovation. The unit of analysis in this study are individuals, such as, farmers who assumed to make rational decision before deciding to do farming activities. Population was all farmers in Ciburuy village. Study respondents are the owner and tenant farmers that selected by using simple random sampling. The conclusion of this studies are (1) Farmer’s positive perception has a tendency to higher percentage than farmer’s neutral perception of organic farming. This suggests that the implementation of organic farming was influenced by farmer’s perception. (2) In the broad-land area category, has a tendency to higher percentage than narrow-land area. This suggests that farmer’s perception about the characteristic of organic farming innovation was influenced by farmer’s broad-land area. (3) Farmers who dare to take a middle risks, has a tendency to neutral perception of organic farming innovation. This suggest that farmer’s perception about the characteristic of organic farming innovation was influenced by farmer’s courage to take a middle risks. (4) In innovative categories, farmer’s neutral perception has a tendency to higher percentage than less-innovative categories. This suggests that farmer’s perception about the characteristic of organic farming innovation was influenced by farmer’s innovativeness. (5) In farmer’s categories about highly exposed to information, has a tendency to higher percentage than exposed to information categories. This suggests that farmer’s perception about the characteristic of organic farming innovation was influenced by farmer’s ability to expose the information. (6) In farmer’s cosmopolite categories, has a tendency to higher percentage than farmer’s not cosmopolite categories. This suggests that farmer’s perception about the characteristic of organic farming innovation was influenced by farmer’s ability to live out from their birth place.

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.
