Judul: Analisis Faktor Ekonomi yang Mempengaruhi Laju Inflasi Negara Anggota ASEAN dengan Regresi Data Panel
Abstrak: Panel data regression model is the regression model using panel data which is a combination of cross section data and time series data. To estimate the panel data regression model, there are 3 approaches, those are pooled least square, fixed effect model, and random effect model. Parameters on pooled least square approach be estimated by Ordinary Least Square (OLS) method. On fixed effect model approach, parameters be estimated by OLS with the addition of dummy variable. Parameters on random effect model be estimated by Generalized Least Square (GLS). This research aims to estimate the panel data regression model to the data rate of inflation percentage of ASEAN member countries in 2000-2008 to know the economic factors that affect the inflation rate. The results of panel data analysis shows that the appropriate panel data regression model for these data is the fixed effect model with weighting (cross section weights) and white heteroscedasticity. This model indicates that the Consumer Price Index and money growth significantly affected the inflation rate of the ASEAN member countries.

Judul: Analisis Dampak Inflasi terhadap Pertumbuhan Ekonomi di Negara ASEAN+5
Abstrak: Negara ASEAN+5 menunjukkan perkembangan inflasi dan pertumbuhan ekonomi yang berbeda-beda. Terdapat pola hubungan antara inflasi dengan pertumbuhan ekonomi. Ada saat peningkatan inflasi diikuti dengan menurunnya laju pertumbuhan ekonomi ataupun sebaliknya. Peningkatan inflasi dibarengi dengan peningkatan pertumbuhan ekonomi maupun sebaliknya. Hal ini menarik untuk dianalisis lebih lanjut. Tujuan dari penelitian ini adalah untuk menganalisis dampak inflasi terhadap pertumbuhan ekonomi di negara ASEAN+5. Periode analisis yang digunakan dalam penelitian yaitu dari tahun 1995-2014 dengan menggunakan metode Fixed Effect Model panel statis. Hasil penelitian menunjukkan bahwa terjadi dampak negatif antara inflasi dan pertumbuhan ekonomi di negara ASEAN+5. Oleh karena itu bank sentral harus menjaga tingkat inflasi agar tidak menghambat laju pertumbuhan ekonomi di negara ASEAN+5. Serta melakukan peningkatan kerja sama dalam keterbukaan perdagangan seperti perdagangan internasional dan pembentukan modal melalui investasi. Diharapkan dengan hal itu dapat meningkatkan laju pertumbuhan ekonomi di negara ASEAN+5.

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
