Judul: Resouce allocation on small farms in Bogor Indonesia
Abstrak: This study was based on data obtained from a random sample of farms near the provincial road in the district Leuwiliang, Bogor, Indonesia. The major objective of the study was to analyze the 1962 economic organization of farms in this area with respect to 4 input categories. These are land, animal labor, human labor and current expenditures, the latter consisting of seed and fertilizer costs. hypothesized that farm resources were not used efficiently. The results of the study indicate that, by using the present method of production, resources had not been used in the optimum combination. Too little fertilizer and too much human labor had been applied. Farm sizes should be increased, and necessary changes in the input combination need to be made, if more profitable farm operation is desired. Further, it was concluded that the optimum input combination to achieve maximum profit should not be recommended, as long as there is no possibility of finding other uses for the released farm labor. Based on this conclusion, the importance of balanced economic growth, implicating the efficient use of resources, in both sectors of agriculture and industry is emphasized.

Abstrak: This study was based on data obtained from a random sample of farms in Kota Marudu, Kota Belud and Tuaran districts. The main objective of the study was to analyze the 1978 economic organization of farms in the area with respect to three input categories: Land, human labour and current expenditures. It vas hypothised that farm resources were not efficiently used. The results of the study indicate that, by using the then present method of production, resources had not been utilized in the optimum combination. Too little current expenditures had been incurred and too much human labour had been utilized. Fara size should be increased, and necessary changes in the input combination need to be made, if more profitable farm operation is desired. It was concluded that the optimum input combination to attain maximum profit should not be recommended, as long as there is no possibility of finding other uses for the released farm labour. Hence, based on this conclusion, the importance of balanced economic growth, implicating the efficient use of resources, in both secters of agriculture and industry is phasized.

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.
