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: 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
