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: 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: Studi Taksonomi Katak Subgenus Papurana (Lesson, 1831) dari Halmahera (Anura, Ranidae, Hylarana), Studi Taksonomi Katak Subgenus Papurana (Lesson, 1831) dari Halmahera (Anura, Ranidae, Hylarana
Abstrak: I reevaluated taxonomic of subgenus Papurana position from Halmahera based on morphological and molecular analyses. My results show that two separate species occur on the Halmahera Island, each nested within two distinct clades (hereafter papua clade and celebensis clade), one of which corresponds to H. moluccana (celebensis clade) and the other to an unidentified species (papua clade). By p-distance ranging from 6.9 to 11.5% on the 16S rRNA gene, the unidentified species (Hylarana sp.) is genetically different from all congeners of the papua clade. The Hylarana sp. can be distinguished from all congeners by following combination of charactes: vomer teeth in two oblique rows with narrow inter-vomer distance; snout rounded dorsally; dorsum with few scattered cone-shaped tubercles that are black with white tips; distinct skin folds (ridges) on the dorsal side of the thigh coinciding with dark brown cross bars; a marbled pattern on the ventral side of the thigh and yellowish groin. I also present new data for H. daemeli, H. volkerjane, and H. arfaki from the western region of Papua. Furthermore, I found that H. celebensis has numerous mtDNA lineages, indicating cryptic diversity within the celebensis clade. The discovery of two separate species on Halmahera necessitates more research into the biogeographic history of Hylarana in Northern Moluccas.
