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: Prenilasi Senyawa β-Diketon sebagai Prekursor 3-Prenilflavon
Abstrak: One group of flavonoids that has not been commonly synthesized is 3- prenylflavone. The main objective of this experiment was to synthesize precursor of 3-prenylflavone. Firstly, β-diketone was synthesized via 4 steps from phenol as starting compound with total yield of 24%. Prenylation of β-diketone with prenyl bromide and K2CO3 base produced 4 fractions which were separated by using preparative thin layer chromatography (PTLC) with n-hexane:EtOAc (8:2) as the eluent. Fraction with Rf = 0.80 was further separated by using preparative PTLC with n-hexane:EtOAc (99:1) as the eluent. Two fractions were obtained with Rf = 0.38 and 0.42. The first fraction has been characterized as diprenylated β-diketone with 49% yield. Application of protecting group on the phenolic OH group in β- diketone are needed to obtain monoprenylated β-diketone which can be further cyclized into 3-prenylflavone
