Judul: Pengaruh Makroekonomi dan Indeks Saham Syariah Internasional terhadap Indeks Saham Syariah Indonesia
Abstrak: Data kapitalisai pasar Bursa Efek Indonesia menunjukkan saham syariah Indonesia cenderung mengalami peningkatan. Kinerja saham syariah Indonesia direpresentasikan oleh Indeks Saham Syariah Indonesia (ISSI). Penelitian ini bertujuan untuk mengetahui faktor yang memengaruhi ISSI dalam jangka panjang maupun jangka pendek. Data yang digunakan berupa data deret waktu bulanan dari Mei 2011 sampai Desember 2018 dan dianalisis menggunakan metode vector error correction model (VECM). Peubah makroekonomi yang digunakan yaitu exchange rate (ER), consumer price index (CPI), jumlah uang beredar di Indonesia (M2), dan sertifikat Bank Indonesia syariah (SBIS). Saham syariah internasional yang digunakan yaitu Dow Jones Islamic market Europe index (DJIEU), Dow Jones Islamic market Malaysia index (DJIMY), Dow Jones Islamic market US index (IMUS), Dow Jones Islamic market Greater China index (DJIGC), dan Dow Jones Islamic market Japan index (DJIJP). Hasil penelitian ini menunjukkan lag optimum yang diikutsertakan dalam model berdasarkan nilai AIC terkecil adalah lima. Terdapat hubungan jangka pendek dan jangka panjang antar peubah. Peubah yang memiliki pengaruh jangka pendek terhadap ISSI yaitu ISSI itu sendiri, ER, DJIGC, DJIMY, dan DJIJP. Selain itu, terdapat hubungan jangka panjang antara peubah ISSI, ER, M2, CPI, SBIS, IMUS, DJIGC, DJIJP, DJIMY, dan DJIEU.

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
