Judul: Analisis Sektor Unggulan dalam Perekonomian Kota Bogor (Periode 2006-2012)
Abstrak: This research aims to analyze the leading economic sector of Bogor City in 2006-2012. The analysis used in this research is the contribution analysis of sector, Location Quotient (LQ), Shift Share (SS), ratio of growth models and overlay (from PB, RPs, and MRP). This research is conducted on the nine economic sectors and specifically on 28 economic subsectors of Bogor City. The data used in this research is the Gross Domestic Product (GDP) of Bogor City and GDP of West Java Province in 2006-2012. The result showed that there are three leading sectors, which are trade, hotel, and restaurant sector, manufacturing sector, and electricity, gas, and water supply sector. As for the subsector, there are five leading subsector, which are wholesale and retail trade subsector, textile, leather good, and footwear subsector, water supply subsector, financial institutions other than bank subsector, and building leasing subsector.

Judul: Analisis Struktur Ekonomi dan Sektor Unggulan di Kabupaten dan Kota Sukabumi (Periode Tahun 2007-2013)
Abstrak: Economic growth, economic structure and the decrease of inequality is of success barometer of economic development. This research aims to analyze the economic structure, growth sectors of the economy and leading economic sector at Regency and City of Sukabumi in 2007-2013. The secondary data of this research is limited from 2007 to 2013 with the method of contribution analysis of sector, shift share, location quotient, MRP and overlay. Economic structure in Regency and City of Sukabumi in 2007-2013 based on tertiary sector. The results of this research show that according to the method of shift share, the sector has a progressive growth in Sukabumi Regency is construction sector and trade, hotel, and restaurant sector. While in the Sukabumi City is the electricity, gas, and water sector, trade, hotel, and restaurant sector, and transport/communications sector. Moreover, the results of overlay method show the leading sectors in the Sukabumi Regency is the mining sector. While the leading sector in the Sukabumi City is the construction sector, trade, hotel, and restaurant sector and transport/communication sector.

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.
