Faktor-faktor yang mempengaruhi luas pengungkapan sukarela dan implikasinya terhadap asimetri informasi

Abstract: Penelitian ini bertujuan untuk mendapat bukti secara empiris serta menganalisis pengaruh faktor-faktor yang mempengaruhi luas pengungkapan sukarela dan implikasinya pada asimetri informasi. Populasi dalam penelitian ini adalah laporan tahunan perusahaan sektor industri barang konsumsi yang terdaftar di Bursa Efek Indonesia tahun 2010-2011. Pengambilan sampel dilakukan dengan metode purposive sampling yang menghasilkan 46 sampel tahun 2010-2011. Penelitian ini dilakukan dengan dua analisis regresi linear terpisah, tahap pertama merupakan regresi linear berganda dan analisis tahap kedua merupakan analisis regresi linear sederhana. Hasil penelitian ini menjelaskan pada model penelitian tahap pertama, porsi kepemilikan saham publik berpengaruh positif terhadap luas pengungkapan sukarela. Likuiditas perusahaan berpengaruh negatif terhadap luas pengungkapan sukarela. Sedangkan umur listing dan ukuran KAP tidak berpengaruh terhadap luas pengungkapan sukarela. Selanjutnya untuk model penelitian tahap kedua, variabel luas pengungkapan sukarela terbukti memiliki pengaruh negatif terhadap asimetri informasi. Abstract This study aims are to obtain empirical evidence and to analyze the factors that affect toward extensive voluntary disclosure and the implications for the information asymmetry. The population in this study are the companies' annual reports of consumer goods manufacturing sector listed in Indonesia Stock Exchange for year of 2010-2011. The sampling technique is purposive sampling method which results for 46 samples in 2010-2011. The research was commited by two separated linear regression analyzes, the first stage is a multiple linear regression and the second stage of analysis is a simple linear regression analysis. The results of this study describes the first stage of the research model, the public shareholding portion has a positive effect of voluntary disclosure. Liquidity has a negative effect of voluntary disclosure. Meanwhile, the age listed and size of the public accounting firm do not affect toward extensive voluntary disclosure. Furthermore, for the second stage of the research model, the extensive voluntary disclosure variable has proven that it has a negative impact on information asymmetry.

Deactivation and Regeneration of Ni/ZA Catalyst in Hydrocracking of Polypropylene

Abstract: Normal 0 false false false MicrosoftInternetExplorer4 The phenomena of catalyst deactivation and the effects of regeneration method on the characteristics and activity of Ni/ZA catalyst after being used in a continuous cracking reaction of polypropylene have been studied. Ni/ZA catalyst was prepared using sonochemical method with total metal intake of 4%. Characteristics and activity of fresh, spent, and regenerated catalyst were evaluated to get a better understanding about the catalyst deactivation. Characteristics which have been observed include catalyst acidity, porosity, crystallinity, and surface morphology. Catalytic activity test of Ni/ZA catalyst on polypropylene cracking reaction at temperature of 500 °C with H 2 flow rate of 20 mL/min and catalyst:feed ratio of 1:2 (w/w) showed the decrease of some catalyst characteristics such as specific surface area, total pore volume, and acidity due to coke fouling over a five-times continuous experiment. Regeneration of catalyst with oxidation-reduction method has been able to increase the activity and acidity of catalyst up to 7.47% and 38.54%, respectively, compared to those of spent catalyst, while the catalyst surface area and total pore volume decreased up to 32.83% and 26.92%, respectively. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}

Computer-Based Experiment of Free Fall Movement to Improve the Graphical Literacy

Abstract: The purpose of this study is to develop computer-based experiment of free fall movement to improve the graphical literacy of the Physics Education students. This study employed quasi-experimental design, particularly the pre-test and post-test control group design. The sample was 58 students of the first semester of Physics Education study program. They were divided into two groups, namely 38 students constituted an experimental group and 20 students constituted the control group. Both groups joined learning activities at laboratory and classrooms with the same topic which is the free fall movement. Computer-based learning models were used to design learning activities for the experimental group, while the control group used a traditional learning model with manual experiment with stopwatch and never use experiment tool of free fall movement. It was indicated in this study that the use of such learning model improved the graphical literacy capability better than the traditional learning, which covered ability to identify experimental variables, using the experimental tools, making a graph, formulating mathematical equation, making predictions on the basis of the graph.

Creative Thinking Analysis, Motivation and Concept Mastery on Learning of Cooperative Discovery Model in Elementary School

Abstract: The reason to do this research is because the creative thinking ability, motivation and mastery concept still less than optimal. The purpose of this research is to analyze the improvement of creative thinking ability, motivation and mastery of students’ concepts through cooperative discovery learning model. This research is quantitative research and design experimental with nonequivalent control group. The population in this research is the fifth grade students’ of Rejosari 02 and Rejosari 03 elementary schools. The sample of this research is choosen by using purposive sampling technique. The are 5a obtained 51 students as a control class and class 5b, 50 students as an experimental class. The research instrument is in the form of tests of creative thinking ability, questionnaire of learning motivation and concept of mastery test. The hypothesis test using the N-gain test and independent sample t-test. The result showed as follows: (1) the improvement of students’ creative thinking ability taught by using cooperative discovery learning of, is in category and those who average are in medium category. (2) the improvement of students’ learning motivation that taught by using cooperative discovery learning is of 82.12 and that of conventional learning is of 76.69. (3) There is a difference in the mastery of students' concepts that taught by using cooperative discovery learning and the conventional learning. So it can be concluded that by using cooperative discovery learning are the students’ creative thinking, motivation and concept mastery higher than that of conventional learning. This research gives the implication that cooperative discovery learning is suitable to use in the fifth grade of elementary school to increase the students’ creative thinking, motivation and as.

Analysis of Factors Affecting Manufacturing Companies in Indonesia Performing a Switching Auditor

Abstract: This study aims at analyzing the influence of the Public Accountant Firms Size, Size of Company, Financial Distress, Audit Opinion and Management Turnover toward Auditor Switching. The population of this study is a manufacturing company listed on the Indonesia Stock Exchange during the period 2011-2015 consisting of 134 companies. The sample was obtained by purposive sampling technique which resulted in the sample of 26 companies. Methods of data analysis using logistic regression and SPSS 21 using data and other information obtained from Annual Report. Results of this study shows that the Public Accountant Firms Size and Management Turnover have significant impact toward auditor switching, size of company have influence auditor switching. Financial distress and audit opinion did not effect auditor switching significantly. The value of Nagelkerke R Square is 0.283. conclusions of this study is the Public Accountant Firms Size and Management Turnover have significant impact toward auditor switching, size of company have influence auditor switching. Financial distress and audit opinion did not effect auditor switching significantly.
