Judul: The Effect of Financial Leverage and Profitability on Income Smoothing on the IDX Quality 30 Non Bank Index for the Period of 2015-2019
Abstrak: Manajemen perusahaan memiliki wewenang atas laporan keuangan yang dikeluarkan perusahaan. Manajemen seringkali berupaya merombak laba atau disebut dengan rekayasa laba. Salah satu teknik rekayasa laba adalah perataan laba yang mengatur laba dengan mengurangi fluktuasinya. Penelitian ini bertujuan menganalisis pengaruh pengungkit keuangan dan profitabilitas terhadap perataan laba. Objek penelitian adalah indeks IDX Quality 30 (IDXQ30) Non Bank periode 2015-2019. Data yang digunakan merupakan data sekunder yang diperoleh dari laporan keuangan perusahaan selama periode 2015-2019 serta studi literatur. Metode yang digunakan adalah analisis regresi logistik biner dengan Debt to Asset Ratio (DAR), Debt to Equity Ratio (DER), Return on Asset (ROA), dan Net Profit Margin (NPM) sebagai variabel independen serta Indeks Eckel sebagai variabel dependen. Hasil penelitian menunjukkan bahwa secara simultan DER, ROA, dan NPM berpengaruh signifikan terhadap perataan laba. Secara parsial, DER dan ROA tidak berpengaruh terhadap perataan laba, sedangkan variabel NPM berpengaruh negatif signifikan terhadap perataan laba., Management has the authority over the financial statements issued by the company. Much of earnings management is trying to overhaul profits or what is called earnings engineering. One of the profit engineering techniques is income smoothing, which rules profits in order to reduce fluctuation. This study aims to analyze the effects of financial leverage and profitability on income smoothing. The object of this research is the IDX Quality 30 index (IDXQ30) Non Bank for the 2015-2019 period. The data used is secondary data obtained from the companies’ financial statements during the 2015-2019 period and literature studies. The method used in this research is binary logistic regression analysis with Debt to Asset Ratio (DAR), Debt to Equity Ratio (DER), and Return on Assets (ROA), and Net Profit Margin (NPM) as independent variables and Eckel Index as dependent variable. The results showed that simultaneously DER, ROA, and NPM have a significant effect on income smoothing. Partially, DER and ROA have no effect on income smoothing, while NPM variable has a significant negative effect on income smoothing.

Judul: Analisis Pengaruh pada Faktor-Faktor Income Smoothing dengan Gender sebagai Variabel Moderator pada Emiten Perbankan 2008-2012
Abstrak: Management can intervene in the process of preparation of financial statements for external parties by way of leveling, raising, and lowering the profit reporting. One pattern of earnings management in a way that is leveling Income Smoothing reported income so as to reduce fluctuations in earnings are high. The sample was 26 banks listed on IDX period 2008-2012 and analyzed using the SPSS multiple linear regression testing and moderation regression model to identify variables that influence the gender variable Return on Assets (ROA), Net Interest Margin (NIM), and Debt to Equity Ratio (DER) to variable income smoothing through the F test and T test The results showed that both simultaneously ROA, NIM, DER and three variables are moderated by gender significant effect on income smoothing. Partial test also showed that the ROA, NIM, DER, variables ROA and NIM gender moderated significantly influence income smoothing, while DER moderated by gender has no effect.

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.
