Judul: Faktor-faktor yang Memengaruhi Tabungan Nasional: Studi Empiris di 28 Negara (2007-2011)
Abstrak: Based on Solow growth theory, saving is one of the factors of high output. Some researches show factors that influence national saving, such as growth, inflation, real interest rate, and Age Dependency Ratio. This research compares determinants of national saving in poor country, developing country dan developed country This study used static panel data for 6 poor countries, 11 developing countries and 9 developed countries. This study used annual data from 2007-2011. Variables used in this research are national saving, budget deficit, inflation, real interest rate, growth, and Age Dependency Ratio. The result shows that determinants of national saving in poor countries are Age Dependency Ratio, budget deficit, and inflation. In Developing countries, the determinants are Age Dependency Ratio, growth and budget deficit. While in developed countries, the determinants of national saving are Age Dependency Ratio, budget deficit, and real interest rate.

Judul: Faktor-Faktor yang Memengaruhi Utang Luar Negeri Pemerintah: Uji Panel Kointegrasi Periode Tahun 2000-2013
Abstrak: External debt in almost countries all over the world recently has become a popular issue. All countries, either developing or developed ones have chosen external debt as their option in order to tackle budget deficit or even as one of stimulus ways to escalate performance of national development. However, the matter comes when the allocation of this so called external debt is usually not directed to some productive sectors. This study analyses which factors may properly influence the government external debt of developing and developed countries which represent some different areas. The Panel Cointegration approach is employed to investigate whether the existing relationship on the model is long run relationship or not. Overall, the findings of this study shows that these variables; exchange rate, GDPP, saving, inflation and interest rate significantly affect external debt, otherwise inflation and interest have no significant impact on external debt. Furthermore, all variables are cointegrated so the model has a long run relationship.

Judul: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol
