Judul: Konvergensi Indeks Pembangunan Manusia di Provinsi Banten
Abstrak: Neoclassical economists stated that the level poorer regions would tend to grow faster than the richer regions. This is because of the diminishing marginal returns to capital in the richer regions, as the level of capital per labor is relatively high in these regions. Which in turn will catch up convergence income (wealth). So it will happen by itself without the need for government policy. Some economists opposed this theory, such conditions never happen without any support of government policy. In fact income convergence that never actually happened, it was economies leads to divergence. Based on the theory, in this study would like to know whether the Human Development Index in Banten Provence leading to convergence or divergence during the period 1994-2009. In which the object of research include (Lebak, Pandeglang, Serang and Tangerang) Regency, (Tangerang and Cilegon) Municipal. Using panel data regression model in data analysis techniques are expected to capture the issues can not captured and explained by analysis time series and cross section. Use of the Human Development Index as the object of research because as one indicator of achievement of government's performance in human resource development framework that was introduced by UNDP in 1990. Based on these results can be concluded there was a tendency in Banten Human Development Index has led to a marked convergence with the sigma convergence and beta convergence is negative.

Judul: Disparitas Antar wilayah dan Determinan Pertumbuhan Ekonomi di Provinsi Jawa Barat dan Banten
Abstrak: The economy of a region portrayed through economic growth as well as one indicator to see the results of the development that has been done and is useful for determining the direction of future development. In infrastructure development, government's role as a very strategic mobilizer in supporting economic growth, anddisparityof regional became decreasing and development expected to convergence. West Java Provincial Government has developed the initial concept development and two three Metropolitan Growth Center. This concept was developed by considering the strategic position of Metropolitan Areas (Bodebek Karpur, Bandung and Cirebon) as the center of population agglomeration, and economic and social activities, as well as Growth Center (Palabuhanratu and Pangandaran) as the center of economic growth that has the potential for growth and development of the region in another areas and macro conditions in Indonesia. Policy to accelerated development of the region through increased economic growth and reduction of disparities to push economic growth, followed by the even distribution of income. Past studies have shown that the development of infrastructure such as transport infrastructure, electricity and telecommunications networks and the provision of clean water is essential in order to improve the economy in a region. Infrastructure facilities needed not only by households but also by the business community. Infrastructure improvements are expected to bring prosperity and accelerate economic growth. Areas with adequate infrastructure has a greater advantage in attracting investment into the region, causing the area will be growing faster than areas with poor infrastructure. This is due to the opening of the isolation of the area so that access to the various factors of production may be possible to open up the movement of the region's economy. The purpose of this study is: First, analyze the regional economic disparities district/ City in the province of West Java and Banten. Second, Testing the convergence between the district/ city in the province of West Java and Banten approach Gross Regional Domestic Product. Third, analyze the determinants of disparities between regions and economic growth in the Province of West Java and Banten. Based results of research on disparities between regions and the determinants of economic growth in the Province of West Java and Banten in the period 2004 to 2010 can be drawn some conclusions as follows: (1) Economic growth in the City and County in West Java and Banten from 2004 to 2010 was very volatile. The results of calculations using Williamson indeks 2004 to 2010 in the province of West Java and Banten quite high. (2) Infrastructure development in Indonesia during the period of 2004 to 2010 in general has increased. Beta convergence of GDP Banten value greater when separated with West Java during joining West Java. The half Life needed to close the gap in Banten faster than in West Java. (3) The result of disparities between regions and estimate the determinants of economic growth based on existing data indicates that the electrical and water variables influence positively the regional economic growth. Water infrastructure elasticity is greater than the elasticity of electricity infrastructure. While the road infrastructure influence negatively effect the

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.
