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: Analisis Pengaruh Variabel Makroekonomi terhadap Perkembangan Indeks Saham Syariah Indonesia (ISSI).
Abstrak: Investasi memiliki peran penting dalam perekonomian, karena investasi dapat mengatasi permasalahan sektor riil yang berkaitan dengan modal. Saat ini investasi syariah sedang berkembang di pasar modal syariah khususnya saham syariah yang memiliki Indeks Saham Syariah untuk menganalisis kondisi pasar terakhir sebagai pertimbangan bagi investor untuk berinvestasi. Penelitian ini bertujuan untuk menganalisis pengaruh variabel makroekonomi terhadap perkembangan Indeks Saham Syariah Indonesia (ISSI) periode Mei 2011 hingga Desember 2016 dengan menggunakan metode Vector Error Correction Model (VECM). Variabel Makroekonomi yang digunakan dalam penelitian ini yaitu BI-Rate, Inflasi, Indeks Produksi Industri (IPI), Nilai tukar rupiah terhadap dollar (KURS), Jumlah uang beredar (M2), Harga Minyak dunia (OP), dan Dow Jones Islamic Market United State (DJIMUS). Hasil estimasi VECM pada jangka pendek menunjukkan variabel DJIMUS signifikan terhadap ISSI. Pada jangka panjang, hasil estimasi VECM menunjukkan bahwa variabel IPI, dan DJIMUS berpengaruh positif secara signifikan terhadap ISSI, sedangkan variabel BI-Rate, KURS, dan OP berpengaruh negatif secara signifikan terhadap ISSI.

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.
