Judul: Pengaruh Tata Kelola Perusahaan Dan Tanggung Jawab Sosial Perusahaan Terhadap Kinerja Keuangan Pada Perusahaan Indeks Kompas100.
Abstrak: Kegiatan operasional perusahaan dilakukan dengan tujuan utama untuk memaksimalkan laba bagi para pemegang saham. Namun selain itu, perusahaan juga berkewajiban untuk memberikan kontribusi pada pembangunan masyarakat. Untuk mengakomodasi tujuan dan kewajiban perusahaan tersebut dapat diterapkan suatu sistem yang disebut tata kelola perusahaan (corporate governance/CG). Perusahaan dapat menerapkan tanggung jawab sosial perusahaan (corporate social responsibility/CSR) sebagai langkah nyata dalam memberikan kontribusi kepada pembangunan masyarakat. Penerapan CG dan CSR saling berhubungan karena CSR merupakan konsekuensi dari penerapan CG. Penelitian dilakukan pada seratus perusahaan yang terdaftar dalam indeks Kompas100 untuk mengetahui pengaruh penerapan CG terhadap pengungkapan CSR, pengaruh penerapan CG terhadap CFP, pengaruh pengungkapan CSR terhadap CFP, dan pengaruh penerapan CG terhadap CFP dengan pengungkapan CSR sebagai variabel pemoderasi. Perusahaan indeks Kompas100 dipilih karena perusahaan tersebut dinilai mempunyai kinerja yang baik yang dapat dilihat pada return sahamnya dari tahun 2010 sampai tahun 2013 selalu diatas return saham IHSG. Analisis untuk mengetahui hubungan ketiga variabel tersebut dilakukan dengan analisis structural equation modeling (SEM) dengan pendekatan partial least square path modeling. Hasil penelitian menunjukkan bahwa penerapan CG berpengaruh positif terhadap pengungkapan aktivitas CSR. Namun penerapan CG berpengaruh negatif terhadap kinerja keuangan perusahaan. Pengungkapan CSR berpengaruh negatif terhadap kinerja keuangan. Penerapan CG berpengaruh negatif terhadap CFP melalui pengungkapan CSR sebagai variabel pemoderasi.

Judul: Pengaruh Corporate Governance Terhadap Harga Saham (Studi Kasus Pada Perusahaan Tercatat Indeks KOMPAS100 Tahun 2014-2018)
Abstrak: Praktik good corporate governance memiliki peranan sangat penting dalam mengarahkan dan mengelola suatu perusahaan. Salah satu penyebab krisis keuangan yang dialami Indonesia pada tahun 1998 dan 2008 adalah lemahnya praktik tata kelola suatu perusahaan di Indonesia. Perkembangan praktik tata kelola di Indonesia masih sangat tertinggal dengan negara ASEAN lainnya, berdasarkan hasil penilaian terakhir ASEAN Corporate Governance Scorecard (ACGS) Indonesia berada di peringkat ke 4 dari 6 negara peserta ACGS. Penelitian terdahulu menyatakan bahwa good corporate governance mempengaruhi harga saham suatu perusahaan. Penguatan corporate governance pada perusahaan akan mengurangi agency problem dan tercipta pengelolaan perusahaan yang transparan, akuntabel, tanggung jawab, independen dan wajar. Hal ini tentu akan menarik minat investor dalam menginvestasikan dananya sehingga akan mempengaruhi harga saham perusahaan tersebut. Harga saham akan berfluktuasi seiring dengan permintaan dari saham tersebut. Penelitian ini bertujuan untuk menganalisis tingkat kepatuhan perusahaan Indeks KOMPAS100 dalam menerapkan dan mengungkapan praktik Good Corporate Governance pada 2014 – 2018 dan menganalisis pengaruh Good Corporate Governance terhadap Harga Saham. Jumlah sampel penelitian adalah 56 perusahaan yang dipilih berdasarkan teknik purposive sampling dengan 3 kriteria. Jenis data yang digunakan data sekunder dari laporan tahunan perusahaan, situs web dan informasi resmi regulator atau perusahaan. Teknik pengolahan data menggunakan analisis data panel dengan bantuan perangkat lunak STATA 16. Hasil penelitian menunjukkan bahwa jumlah Komisaris Independen, return on assets, price to earning ratio dan price to book value memiliki pengaruh yang signifikan terhadap harga saham ke arah positif. Variabel jumlah rapat Dewan Komisaris, jumlah Direksi, jumlah rapat Direksi, pendidikan/pelatihan sekretaris perusahaan dan earning per share memiliki pengaruh positif namun tidak signifikan. Hasil uji simultan menunjukkan adanya pengaruh positif signifikan dari sembilan variabel independen terhadap harga saham. Hasil pengujian koefisien determinan menunjukkan besarnya adjusted R-square adalah 0.9609 atau 94.81%., Good corporate governance practice plays a very important role to direct and manage a company. One of the causes of the financial crises that Indonesia experienced in 1998 and 2008 was the weak corporate governance practices. The development of governance practices in Indonesia is still lagging behind other ASEAN countries. Based on the results of the latest assessment of the ASEAN Corporate Governance Scorecard (ACGS), Indonesia is in 4th place out of 6 ACGS participating countries. Previous research statef that good corporate governance affects the stock price of a company. Strengthening corporate governance in companies will reduce agency problems and create transparent, accountable, responsible, independent and fair company management. It will certainly attract investors to invest their funds, thus, it will affect the company's stock price. Share prices will fluctuate in line with the demand for these shares. This research aimed to analyze the level of compliance of companies with the KOMPAS100 Index in implementing and disclosing Good Corporate Governance practices in 2014-2018 and analyzing the effect of Good Corporate Governance on Stock Prices. The number of research samples were 56 companies selected based on purposive sampling technique with 3 criteria. The type of data used was secondary data from company annual reports, websites and official information of regulators or companies. The data processing technique used panel data analysis with the help of STATA 16 software. The

Judul: Phylogeography and Species Limits in the Papuan White Snake (Micropechis ikaheka) (Reptilia: Serpentes: Elapidae)
Abstrak: Papua white snake, Micropechis ikaheka, has been distingushed into two subspecies M.i. ikaheka and M.i. fasciatus. However, due to lack of data on their morphology, distribution and ecology, both subspecies often ignored in scintific discussions and refers only byas , Micropechis ikaheka. This study was designed to document the differences between M.i. ikaheka and M.i fasciatus by using scales characteristics and reproductive organ or hemipenes. The study also examine, zoogeography, habitat, diet and cannibalism of both subspecies to better understanding the the ecology of one of the most venomous snakes in the world. This study consists of three topics with method and also different in the size samples, respectively. The first study is the histology and microtopography of the skin were studied using paraffin method and Scanning Electron Microscope (SEM). The second is the hemipenis were examined by following Myers and Cadle (2003), and Zaher and Prudente (2003). The third is the abdominal surgery was carried out to document diet type and the investigate phenomenon of cannibalism in the snake. Specimens for this study came from the collection from Museum Zoologicum Bogoriense (MZB) and Universitas Negeri Papua’s Laboratory (LZU). The research result also indicated that the markers of skin and hemipenis described the same structure and microornamentation in all M. ikaheka groups being compared. Based specimens examined morphological descriptions do not s support the further differentiation in Micropechis. In short, two markers that used in this study could not sufficiently indicate the differences in the level of species and subspecies of M. ikaheka. The study, however, were able to delineate zoogeography and skin color patterns, which fall into four groups: M. i. ikaheka; M. i. fasciatus. M. i. ssp. “intermediate”; and M. i. ssp “black”. This study also revealed that color variations did not overlap in their geographic distribution. It is therefore, it suggested that environmental factors may contribute to the skin color variations. It also assumed that habitat discontinuous and biogeography factors may also cause the loss of the connection between the original populations (vicarians) or follow colonization events (dispersal). The examined of 22 stomach contents of M. ikaheka shows this species is carnivorous, and prey on vertebrates such as amphibians, fish, reptiles, and Mammals. These snakes are opportunistic predators since they prey on all that can be captured, but mainly reptiles (61.5%), followed by mammals and fish (both 15.4%), and amphibians (7.7%). Although categorized as terrestrial animal, the diet study showed that M. ikaheka snakes often go into the water to hunt for fish (the sample from Yapen island), including eel (the sample from Aru island). Based on prey items indentified, there is evidence that M. ikaheka is cannibal. At this time, there still no record on reason for cannibalism, but it is assumed that cannibalism was due to competition between populations and means to control population.
