The objective of the study was to substantiate the influence of selected independent variables for building optimal models of teaching a series of tasks aimed at motor skills development in boys aged 10. Materials and methods. The study involved 32 boys aged 10. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. To achieve the objective set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of learning tasks; pedagogical experiment, methods of mathematical statistics, methods of mathematical experiment planning. In the process of teaching, a method of algorithmic instructions was used. Results. The effect size of the factor varied from series to series. The calculated Cochran's criterion showed that all the groups of experimental data were obtained from the same population. It was found that the variances do not differ for the selected significance level of 0.05.  Each independent variable (X1, X2, X1X2) plays a role in changing the indicator of proficiency in the Mawashi-geri-jodan (roundhouse kick). The constructed mathematical models adequately describe the obtained data. The calculated regression coefficients are statistically significant (Fр < Fkр), which means that the regression model is effective. Throughout the experiment, the independent variable Х1 “number of sets” had a constant positive effect on the target feature (Y). The percentage contribution in the first series of learning tasks was 59.3%, in the second – 88.6%, in the third – 56%, in the fourth – 93.9%, in the fifth – 81.3%, in the sixth – 69.62%. The independent variable Х2 “rest interval” has a negative effect in the first series – 25.9%, in the second series – 10.6%, in the fifth – 9.9%, in the sixth – 13.1%. A positive effect of the first-order interaction (X1X2) was observed in the third series – 29.1%, the fifth – 8.9%, the sixth – 17.28%.  Conclusions. The optimal combinations of conditions for the series of tasks when teaching boys aged 10 the Mawashi-geri-jodan (roundhouse kick) are the following: series 1 – 3 sets, rest interval 60 s; series 2 – 3 sets, rest interval 60 s; series 3 – 3 sets, rest interval 120 s; series 4 – 3 sets, rest interval 60–120 s; series 5 – 3 sets, rest interval 120 s; series 6 – 3 sets, rest interval 120 s.

Several studies related to the effect of audits on taxpayer compliance provide different conclusions. Bergman and Nevarez (2006) find the fact that tax audits negatively affect compliance. In contrast, Gemmel and Ratto (2012) concluded that the audit had a negative effect on the group of taxpayers who obeyed, and at the same time had a positive effect on the group of taxpayers who did not comply. Given the different conclusions, the researcher is interested in testing in the Indonesian context by using the SIDJP data from the Directorate General of Tax for the period 2009-2013.The difference-in-differences approach model implemented in this study adopts Norman Gemmell and Marissa Ratto (2012). The dependent variable is income tax while the independent variable is the dummy variable for group, time and type of audits. Regression results show that the interaction coefficient between the dummy group variable and the time dummy variable which is the difference-in-differences coefficient, has a p-value that is statistically insignificant to reject null hypothesis. It tells that there is no difference in the level of compliance between the audited (corporate) taxpayer and non-audited (corporate) taxpayers. No impact on the level of compliance of taxpayers may come from several reasons, including the small coverage of the tax audits, the existence of the bomb crater effect, and the results of the type of updating audit risk.

This study aims to analyze the profitabilitybetween Islamic Banks and Conventional Banks in Indonesia. This study uses data from 2010 to 2015. The samples used in this study consists of 3 Islamic Banks and 3 Conventional Banks. While the data used is obtained from the financialstatements of each bank stored in the bank website address. Data analysis technique is done by t-test and regression analysis with SPSS 18 application. The estimation results on the t-test showed that the banks used in this study did not have significantmean differences. The result of the regression test shows simultaneously the independent variable of DPK, Equity and Loan only affects the ROA of conventional bank. While partially on conventional banks DPK has a negative effect is not significantto ROA, Equity has a positive effect is not significantto ROA, Loans has a positive effect is not significantto ROA. In Islamic banks DPK has a positive effect is not significantto ROA, Equity has a negative effect is not significantto ROA, Loans has a negative effect is not significantto ROA. From these results can be said that conventional banks more profitablewhen compared to Islamic banks.

This study analyzes the influence of Islamic stocks on corporate sukuk. The object of this study is the outstanding corporate sukuk in Indonesia in 2015-2016. This study aims to analyze the effect of Islamic stock variables, namely the capitalization of the Jakarta Islamic Index and the Indonesian Islamic Stock Index. This research was conducted using quantitative methods. The data source in this study is secondary data. The data in this study were collected in two ways, namely choosing objects based on three elements (social situation) and samples (purposive sampling). The data collection technique in this study is documentation. The results of this study indicate that the Capitalization of the Jakarta Islamic Index (JII) has a significant negative effect on outstanding sukuk because the capitalization coefficient of the Jakarta Islamic Index (JII) is -0.015194 and the significance level of JII is 0.0299 smaller than alpha 0.05. This means that the increase in capitalization that occurred in 2015-2017 had a significant negative effect on the outstanding sukuk which caused the outstanding sukuk to decline. The Capitalization of the Indonesian Sharia Stock Index (ISSI) has a significant positive effect on outstanding sukuk because the capitalization coefficient of the Indonesian Sharia Stock Index (ISSI) is 0.014341 and the significance level of the ISSI is 0,0008 smaller than alpha 0.05 which means an increase in ISSI capital in the year 2015-2017 had a significant positive effect on outstanding sukuk which resulted in outstanding sukuk increasing.
