To maintain all of the jobs they were serious engaged in, information had become an important factor. Their need for informations was inseparable from the problems they experience in both farming and non-farming activities. They need not only farming but also non-farming informations. To meet the need for informations, they tried to get information by visiting many sources of information. The information seeking behavior pattern among the peasants were different depending on the information needed, types of farming activities, and types of jobs other than farming activities. However, while seeking information, they faced a number of constraints (personal, interpersonal, and environmental).

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.
