Judul: Analisis pengaruh pengeluaran pemerintah, investasi, dan tingkat pendidikan tenaga kerja terhadap pertumbuhan ekonomi Indonesia
Abstrak: Produk domestik bruto Indonesia selama periode 2006 hingga 2013 menunjukkan tren yang meningkat, tetapi tingkat pertumbuhannya berfluktuasi. Faktor utama yang menjadi tulang punggung utama pertumbuhan ekonomi, yaitu modal dan tenaga kerja. Penelitian ini melihat perkembangan indikator pengeluaran pemerintah, investasi, dan tingkat pendidikan tenaga kerja sebagai penggerak pertumbuhan ekonomi. Pengeluaran pemerintah dalam bentuk belanja modal serta penanaman modal dalam negeri berpengaruh positif dan signifikan, sedangkan penanaman modal asing tidak berpengaruh signifikan terhadap pertumbuhan ekonomi. Tenaga kerja dengan pendidikan terakhir di level sekolah dasar berpengaruh negatif dan signifikan, sedangkan sekolah menengah pertama berpengaruh negatif dan tidak signifikan terhadap pertumbuhan ekonomi. Tenaga kerja dengan pendidikan terakhir di level sekolah menengah tingkat atas dan perguruan tinggi berpengaruh positif dan signifikan terhadap pertumbuhan ekonomi.

Judul: Pengaruh Pengeluaran Pemerintah, Investasi Swasta, dan Tenaga Kerja Terhadap Pertumbuhan Ekonomi di Indonesia
Abstrak: Economic development is the process of improving the welfare of any one indicator of success is measured economic growth The analytical method is use Engel-Granger cointegration test and Error Correction Mechanism (ECM). The result shows that (1)the realization of the government budget subsidies fluctuated greatly affected the world price of crude oil. Transfer area is the biggest government spending. Realization of private investment in the crisis affected the world economy. (2) The long-term variable subsidy and inflation has a negative significant relationship to economic growth, while private investment have a significant positive relationship In the short term variables inflation and subsidies have negative significantly relationship to economic growth, while private investment, government capital expenditure, the transfer area, and labor force has a significant negative

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.
