Judul: Analisis Kinerja Keuangan PT Jasa Marga Tbk Sebelum dan Setelah Privatisasi
Abstrak: PT Jasa Marga as BUMN has been struggling to do some improvement through Initial Public Offering (IPO) since November, 1st 2007. This research is done to (1) Analyses finances condition trend PT Jasa Marga Tbk during 2004-2013 period then predict during 2014-2015. (2) Compares between financial performance Jasa Marga during four periode before privatization and after privatization. (3) Explains significant factorin financial performance average ratio Jasa Marga, after enterprise is private. The analysis results finances condition trend PT Jasa Marga Tbk shows that enterprise balance and profit end to increase during 2004-2013, and estimated to increase during 2014-2015. While financial performance analysis shows that enterprise solvabilitity level is tend to decrease. Next, liquidity level, profitability, and enterprise activity ends to riseduring 2004-2013. After signification test is done, it shows some increased scores after privatization which is experienced by average cash ratio, current ratio, ROE, DER and DAR, is not affects significantly. The increasing value which is affects significantly are ROA, NPM and TATO.

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.
