Judul: Analisis Faktor-Faktor yang Memengaruhi Pemindahan Ibukota Negara
Abstrak: One of the possible solutions to overcome the problems of a country’s capital is to move its capital city. The moving of the capital which was well designed and well executed can be a solution to overcome the problems of the nation's capital. There are three common reasons for moving the capital, namely socio-economic considerations, political considerations, and geographical considerations. Jakarta as the capital of Indonesia has a lot of problems so that the government has discourses about moving its capital. Discourses of moving the capital require further investigation and learning from other countries who had moved its capital. This study aims to determine the factors that affect the transfer of the nation’s capital by analyzing 26 selected countries in the period of 1990, 2000, and 2010, by using logistic regression. Nations that moved its capital in general is developing countries, and has split-type capital cities. The factors that significantly affect the relocation of the capital is the GDP per capita, land area, population, population density, and type of the capital. In the plan of moving its capital, the government should use the split-type capital since this type of capital is more likely to be done.

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: 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.
