Judul: Analisis Sektor Unggulan dan Ketimpangan Ekonomi di Provinsi Banten (Periode tahun 2002-2011).
Abstrak: Banten Economic growth during 2002 – 2011 has increased positively. This growth happened because of the role of superior sector at Banten province economic areas. Based on identification using analysis method LQ, Shift Share and Klassen typology has found four superior sectors at Banten province that are manufacture sector, electricity sector, gas and clean water, trading sector, hotel and restaurant, also transportation and communication. Those four sectors are called modern economic sectors. The causes of economic gap of interregional between regency and city at Banten province happened by the differences between of identified superior sector at province level, compared to regency and city level. The undeveloped Banten regency and city has different superior sector compared to superior sector at Banten province. Meanwhile, the developed region has the same superior sector with superior sector at Banten province. The Banten government regulation during 2003 - 2011 which is aimed to create agriculture sector as superior sector has not reached yet. Besides that, the purpose to decrease the interregional economic gap between regency and city during 2003 – 2011 has not reached yet also.

Judul: Kajian Sektor Unggulan Perekonomian Wilayah Provinsi Banten
Abstrak: Implementation of regional develompment in Banten Province hasn’t been optimal because the high number of unemployment and increasing of number of poor people.Government needs to do an integrated planning to expand some sectors,which are able to drive economic region. The main purpose of this study is to analyze the leading sectors of Banten Province. The method of this research is Input-Output table analysis of Banten Province at producer domestic prices in 2010, the classification of 58 sectors aggregated into 9 sectors. Result of the research showed leading sectors in Banten Province are manufacturing industry sector, trade, hotel, and restaurant sector, and transport and communication sector. Sub-sectors that are able to support them are food, beverages, and tobacco industry sector, papper and printing products industry sector, computers, electronics, optics, and electrical equipment industry sector, wholesale, retail trade, and repair of motor vehicles sector, road transport sector and air transport sector.Agriculture sector has a potential as basic sector to increase economic growth and domestic income in South Banten

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
