Abstrak: Good corporate Governance (GCG) is one important thing to notice in a company. GCG is a rule that is arranged by government that has been legally confirmed. The implementation of GCG in every company is surely different but it has to follow the standard that has been made by the government. Company profitability ratio can visualize the finance performance of the company it self eventhough it has to be also supported by another ratio measurement. The value of Return on Asset (ROA) and Return on Equity (ROE) is two aspects on profitability. The purpose of the research to knowing how the influence implementation of GCG on company profitability ratio. According to the value that was measured by the E-Views 6.0 application, the implementation of GCG shows the impact of company profitability ratio. CGPI score is remarked as the independent variable and the range of ROA and ROE of the company remarked as dependent variable.

Judul: Analisis Pengaruh Good Corporate Governance terhadap Kinerja Keuangan dan Harga Saham Perusahaan yang Masuk ke Dalam Pemeringkatan Corporate Governance Perception Index
Abstrak: Good corporate governance (GCG) adalah suatu sistem dan seperangkat peraturan yang mengatur hubungan antara berbagai pihak yang berkepentingan demi tercapainya tujuan perusahaan. Tujuan penelitian ini adalah menguji pengaruh penerapan GCG terhadap kinerja keuangan dan harga saham. Penerapan GCG diproksi dengan skor Corporate Governance Perception Index (CGPI), kinerja keuangan diproksi dengan rasio Tobin’s Q, dan harga saham diproksi dengan harga saham pada penutupan akhir tahun. Sampel yang digunakan pada penelitian ini adalah perusahaan yang terdaftar pada pemeringkatan CGPI dan Bursa Efek Indonesia dari tahun 2007-2011. Berdasarkan hasil uji hipotesis didapatkan bahwa penerapan GCG secara parsial tidak berpengaruh signifikan terhadap variabel kinerja keuangan dikarenakan berdasarkan uji R2 didapatkan hasil bahwa hanya sebesar 8% rasio Tobin’s Q dipengaruhi oleh penerapan GCG sedangkan sisanya dipengaruhi oleh faktor lainnya. Penerapan GCG secara parsial berpengaruh signifikan terhadap variabel harga saham yaitu sebesar 16.2% harga saham dipengaruhi oleh penerapan GCG sedangkan sisanya dipengaruhi oleh faktor lainnya.

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.
