Judul: An Analysis on the Effect of Regional Expansion on Regional Economics Development (Case study of Cimani, West Java Province)
Abstrak: This research is intended to: (1) anal:vze the effect of regional expansion on economic and welfare development in Cimahi, (2) analyze the effects of regim expansion on the Cimahi regional fiscal capacity, (3) anal~/ze the effects of ~nsion toward mobility of Cimahi regional government in developm~nt that i\1lOt based of the main government subsidiary (development subsidy), if the regi'orml autonomy is not firmly implemented. and (4) tr· analyze the feasibil;ty of expan§ion, The methods of analysis lIsed are descriptive analysis, entropy diver~y index analysis, particip'ative analysis, financial <.lId expansion suitability reporEanalysis, The result of this research shows positive affects of Cimah'i oity expanil.on toward the region's economic and welfare- development. Regional exparruon had also a positive impact on the growth of the region's fiscal capacity, but tli value 'of EDI for the regional income indicates that the region's fiscal capacjy has not developed yet. The distl'ibution of regional autonomy has incre$ed the ability of the region in producing its obtaining and financing the area'sS.development, however, the increasing DAU has proven an oecurring deperillency toward the central government.

Judul: Relationship Among Budget Structure and Tipology of Regional problems for Optimazing Regional Development Performance.
Abstrak: The financial crisis beginning in medio 1997 that led to economic turbulence has exerted a negative impact on the economic condition. This condition made development performance became quite low and instable. The misallocation of budget also influenced regional development performance. This fenomena create idea that needs a study about relationship between budget structure and tipology of regional problems for optimizing regional development performance. The purpose of the research are (1) to identify profile of development performances; (2) to measure disparity development among regencies/municipalities in the provinces of West Java and Banten; (3) to measure the correlation among budget structure, tipology problems and development performance; (4) to find principal indicators of development performance. These research use the analytical tool such as: (1) Tabulation Analysis; (2) Location Quotient; (3) Williamson's Index; (4) Correlation and (5) Natural Logarithmic Regression. The result of this research indicates that (1) The structure of economics among regencies/municipalities have led sectors in West Java and Banten. Some regencies/municipalities led in manufacture industries, such as Bekasi (82.87 percent), Bogor (49.27 percent), Purwakarta (44.80 percent), Cilegon (61.84 percent), and Tangerang (56.28 percent). Some regencies/municipalities give large contribution in agriculture sectors such as Subang (42.89 percent), Garut (40.96 percent), Cirebon (37.47 percent), Lebak (40.35 percent), and Pandeglang (36.13 percent); (2) There are lack of development among regencies/municipalities. Williamson's Indices for West Java and Banten are 0.4158 and 0.5846. The figures indicate that disparity of development in Banten is higher than that in West Java; (3) The correlation between growth of Gross Domestic Regional Product (GDRP) and illiteracy rate shows negative coefficient (-0.8) with P-Value 0.000; (4) In the whole are relationship among performance of development, structure of budget and tipology of regional problems. The regression coefficient of allocation of education budget is 0.419. Meanwhile the regression coefficient rate of illiteracy is -0.580. This model have P-Value, Multiple R and R Square respectively 0.000, 0.913 and 0.834. All of the result of the research conclude that (1) The Improving of the matching among the budget patern and tipology regional problems will optimize regional development performance (2) The available of competence human resources will speed the regional development performance.(3) The Larger contribution of education budget will increase the regional development performance.

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.
