Abstract

This research investigates the impact of economic volatility on the market capitalization of the Jakarta Islamic Index(JII) from 2019 to 2021. Analysis of stock prices and returns for companies in this index reveals fluctuations that are correlated with economic disruption. In addition, research explores the significance of financial ratios, especially Return On Assets (ROA), as an important tool for assessing company performance. Economic Value Added (EVA) was also tested as a factor influencing stock returns, producing different results from previous research. Thirteen companies in the JII were the research samples, selected through purposive sampling based on criteria such as consistent registration for three years, annual financial reports for the 2019-2021 period, and not using foreign currency. Data obtained from company reports. This research uses an explanatory quantitative approach, by applying panel data regression and models such as Common Effect, Fixed Effect, and Random Effect. The results of statistical analysis for the EVA variable show that there is no significant influence on the returns of sharia shares listed on the JII. Meanwhile, the ROA variable shows that ROA has a significant effect on stock returns in companies listed on the JII.

Abstract

This research aims to assess the impact of tax extensification and intensification policies on the optimization of local tax revenues, with a case study at the Regional Revenue Agency (BAPPENDA) of Sumedang Regency. This study adopts a quantitative descriptive design utilizing a survey method involving tax officials from the Regional Revenue Agency (BAPPENDA) of Sumedang Regency. The sample was selected using a purposive sampling technique, where participantswere chosen based on predefined criteria. Data were obtained from both primary and secondary sources, with the primarydata collected through questionnaires distributed to 30 respondents. The instrument used a Likert scale ranging from 1 to 5 to measure responses. Analytical methods applied included normality tests, multiple linear regression, Pearson’s product-moment correlation, coefficient of determination, and hypothesis testing using t-tests and F-tests, conducted with IBM SPSS version 25.The findings reveal that tax extensification exerts a positive but statistically insignificant impact on local tax revenue, indicated by a regression coefficient of 0.223, a t-value of 1.928 (less than the critical value of 2.052),and a significance level of 0.064, exceeding the standard threshold of 0.05. Similarly, tax intensification also demonstrates a positive yet insignificant influence, with a regression coefficient of 0.061, a t-value of 0.377, and a significance level of 0.709, all failing to meet statistical significance. Furthermore, the combined effect of both tax extensification and intensification on local tax revenue is also not statistically significant, as reflected by an F-value of 1.946 (below the critical F-value of 3.09) and a significance level of 0.162, which is higher than 0.05.
