Judul: Analysis of Economic Structure and Factors that Influence Job Opportunity in Jakarta
Abstrak: This study aimed to determine the structure of economy and factors that affect job opportunity in Jakarta. Author used Shift Share Analysis, Location Quotient and Multiple Regression that was estimated with Least Square Method (OLS) in Semi-Log form. To examine the relations that happened on job opportunity, author used the regional autonomy as a dummy variable, FDI, domestic investment, GDRP, and investment lending rate, with time series data from the period 1993 until 2008. The result of Shift Share Analysis and Location Quotient since the implementation of regional autonomy showed that employment growth from the components of national employment growth, industry mix and competitive advantage were dominated by the tertiary sector, such as trade, hotels, and restaurants; transportations and communications sector; financial sector, renting and business services; and services sector. The four sectors above were also a basic sector in expanding job opportunity. The results of Multiple Regression Analysis showed that the dummy variable of regional autonomy, FDI, domestic investment, GDRP, and investment lending rate had simultaneous effect toward job opportunity. And partially, FDI, domestic investment and investment lending rate had significant effect toward job opportunity. Dummy variable of regional autonomy, FDI, domestic investment and GDRP had positive effect and investment landing rate had negative effect toward job opportunity. While dummy variable of regional autonomy and GDRP had positive and not significant effect toward job opportunity.

Judul: Analysis of Structure Change and Sources of Economic Growth in DKI Jakarta: Input Output Model Analysis
Abstrak: This study aims to analyze the role of industrial sector in economic growth of DKI Jakarta Province in 1993, 2000, and 2006. This research is expected to provide information about what sector is superior sector (keysectors) and changes in economic structure in the Province of DKI Jakarta during study period. In addition, through this research could also determine that there are linkages among sectors in the Province of DKI Jakarta and the pattern of changes in sources of output growth. Research method used is the input-output analysis in order to answer the research objectives. Data of Input Output Table of DKI Jakarta Province obtained from BPS (Central Bureau of Statistics) is the data in 1993, 2000, and 2006. The number of sectors that were analyzed and then made the process of aggregation of up to 23 sectors. The results showed that during 1993, 2000, and 2006, the structure of domestic final demand is dominated by the demand among. Components of demand among the source of output growth is the component of household consumption (konsRT) and fixed capital formation (Pmtb). During the study period, sectors that have backward linkages rates above the average power dispersion and that have numbers forward linkage in the above-average sensitivity of dispersion has decreased the number of sectors. Based on the analysis, leading sector during the study period occurred in six sectors, namely; industry sector of Food, Beverages & Tobacco (MKMN), sector of Chemical, Drugs, Cosmetics (KIMOB), sector of Metal, Machinery, and Electronic (LME), sector of Electricity, Gas, and Water Supply (LGAB), sector of Real Estate, and Business Services (REJP), and sector of Other Services (JSLN).

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.
