Judul: Pengaruh variabel makroekonmi domestik dan global terhadap indeks saham konvensional dan syariah di Indonesia
Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh variabel makroekonomi domestik dan makroekonomi global terhadap Indeks Harga Saham Gabungan dan Jakarta Islamic Index. Penelitian ini menggunakan metode Vector Error Correction Model (VECM) dengan data runtut waktu bulanan dari Mei 2004 sampai dengan Mei 2015. Hasil penelitian ini menunjukan bahwa tidak semua variabel makroekonmi domestik dan global yang diamati memengaruhi IHSG dan JII secara signifikan positif maupun signifikan negatif selama periode penelitian. Berdasarkan hasil IRF, IHSG dan JII memberikan respon yang fluktuatif terhadap guncangan yang terjadi pada variabel yang diamati dalam penelitian. IHSG dan JII paling cepat mencapai kestabilan ketika merespon guncangan M2 dan kurs. Berdasarkan hasil FEVD, variabel yang memiliki kontribusi besar dalam memengaruhi IHSG dan JII adalah BI rate. Hal ini membuktikan pasar saham syariah belum bisa lepas dari pengaruh instrumen konvensional yang bertentangan dengan prinsip syariah.

Judul: Analisis Pengaruh Makroekonomi Domestik dan Makroekonomi Global Terhadap Indeks Saham Syariah Indonesia (ISSI) Periode 2011-2014
Abstrak: This study atempts to analyze the effect of domestic macroeconomic variables: namely BI Rate, Inflation, and Exchange Rate (USD/IDR); and global macroeconomic variables: namely World Oil Price, Dow Jones Islamic Market Index US (IMUS), and Hang Seng Index (HSI) against Indonesian Sharia Stock Index (ISSI). This research uses Vector Error Corection Model (VECM) with monthly data from May 2011 to August 2014. The result of this study shows that in the long-run all variables have a significant effect where ISSI is negatively affected by BI Rate, Inflation, and IMUS, dan positively affected by Exchange Rate, World Oil Price, and HSI. In the short-term ISSI is negatively affected by Exchange Rate and Inflation, and positively affected by HSI, and all are significant. In addition, variables affecting ISSI based on their proportion strated from the largerst to the lowest are BI R

Judul: Sintesis Flavon dari Fenol dan Benzoil Klorida
Abstrak: Flavone is a class of flavonoid, commonly found in plants with wide bioactivity spectrum. A widely used flavone synthesis route is through acidcatalyzed oxidative cyclization of β-diketone. In this study, unsubstituted flavone had been synthesized via 5-step from phenol, with 22% yield and successfully increased the yield of previous study on Fries rearrangement of phenyl acetate and benzoylation of o-HAP steps. Phenol was acetylated resulting 93% phenyl acetate. AlCl3-catalyzed Fries rearrangement in 1.5 hour and at 120 °C converted phenyl acetate into o-hydroxyacetophenone (o-HAP) with 40% yield. AlCl3 as catalyst produced o-HAP with higher and reproducible yield compared with BF3·Et2O and ZnCl2. Benzoylation of o-HAP followed by Baker-Venkataraman rearrangement of the ester product using KOH in dried pyridine produced β-diketone 1-(2- hydroxyphenyl)-3-phenylpropane-1,3-dione. The yield of ester and β-diketone were 71% and 85%, respectively. Finally, oxidative cyclization of β-diketone with sulphuric acid as catalyst produced 99% of flavone. The flavone product had been characterized spectroscopically and its melting point as well.
