Judul: Pengaruh Struktur Modal terhadap Kinerja Keuangan Perusahaan Sektor Barang Konsumsi
Abstrak: Sektor barang konsumsi merupakan industri yang memiliki pasar potensial di Indonesia karena tingginya populasi penduduk. Peluang tersebut membuat persaingan pada industri ini semakin ketat. Perusahaan dengan kinerja yang baik akan mampu bertahan dalam persaingan. Keputusan struktur modal yang tepat dapat mengoptimalkan kinerja keuangan perusahaan.Sebanyak 21 perusahaan barang konsumsi periode 2009-2013 menjadi sampel berdasarkan judgment sampling. Penelitian ini dianalisis menggunakan structural equation modeling. DAR dan DER merupakan faktor loading dari variabel laten struktur modal. ROA, ROE, dan NPM merupakan faktor loading dari variabel laten kinerja keuangan. Struktur modal berpengaruh negatif signifikan terhadap kinerja keuangan pada subsektor rokok dan subsektor farmasi. Terdapat pengaruh negatif namun tidak signifikan terdapat pada subsektor kosmetik dan barang perlengkapan rumah tangga. Terdapat pengaruh positif namun tidak signifikan pada subsektor makanan dan minuman dan subsektor barang perlengkapan rumah tangga. Struktur modal berpengaruh negatif signifikan terhadap kinerja keuangan sektor barang konsumsi.

Judul: Pengaruh Struktur Modal, Likuiditas, Modal Kerja, Solvabilitas, Aktivitas dan Pertumbuhan Perusahaan terhadap Profitabilitas Perusahaan.
Abstrak: Profitabilitas mengukur kemampuan perusahaan dalam memperoleh laba. Tingkat profitabilitas yang baik mencerminkan adanya prospek dan potensi perusahaan untuk mempertahankan eksistensinya di dunia bisnis. Tingkat profitabilitas diyakini dipengaruhi beberapa hal diantaranya, struktur modal, likuiditas, modal kerja, solvabilitas, aktivitas dan pertumbuhan perusahaan. Tujuan penelitian ini adalah untuk mengidentifikasi gambaran umum perusahaan sektor industri barang konsumsi di BEI, mengidentifikasi pengaruh struktur modal, likuiditas, modal kerja, solvabilitas, aktivitas dan pertumbuhan perusahaan secara simultan dan secara parsial terhadap profitabilitas pada perusahaan sektor barang konsumsi di BEI. Penelitian ini menggunakan metode pengambilan data sekunder yang diperoleh dari halaman resmi Bursa Efek Indonesia dan halaman resmi perusahaan yang menjadi objek penelitian dengan menggunakan rasio keuangan antara lain, DER, CR, WCT, DAR, TATO, dan rasio pertumbuhan penjualan terhadap ROE. Metode yang digunakan dalam penelitian ini yaitu analisis regresi linear berganda dan uji hipotesis. Hasil dari penelitian ini menunjukkan bahwa modal kerja, solvabilitas dan aktivitas berpengaruh signifikan terhadap profitabilitas, sedangkan struktur modal, likuditas dan pertumbuhan perusahaan tidak berpengaruh signifikan terhadap profitabilitas.

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.
