Abstract

Augmented Reality integrated media has the ability to display concept visualizations. Augmented Reality integrated media on the material of atomic theory development has been developed by previous researchers. This study aims to determine the level of practicality of Augmented Reality integrated media on the material of atomic theory development in learning and its effectiveness on learning outcomes. The type of research used is pre-experimental with a research design, namely One-group Pretest-Posttest Design. The sample class is X E.1 SMA Negeri 1 Sabak Auh. The instrument used in the practicality test is a questionnaire while the effectiveness test uses a cognitive knowledge test instrument in the form of multiple choices. The results of the study obtained a practicality value of 0.92 while the effectiveness test showed an average N-gain value of 0.72 in the high category. Hypothesis testing using the Wilcoxon match pairs test assisted by SPSS at a significance level of 0.05 obtained an Asymp. Sig. (2-tailed) value of <0.000 with the hypothesis decision accepted. So it can be stated that the integrated Augmented Reality learning media on the material on the development of atomic theory has proven effective in significantly improving student learning outcomes.

Abstract

This study analyzes the factors influencing the Sharia Stock Index in Indonesia based on world gold prices, crude oil prices, and BI Rate. Furthermore, to observe more complex conditions, the exchange rate was included as a form of mediation. The data in this study are time-series data collected from May 2011 to December 2023. The data were analyzed using time-series data regression, which involved mediating variables. The results show that world gold prices, crude oil prices, and the BI rate significantly affect the Indonesian Sharia Stock Index. The exchange rate mediates the effect of gold and crude oil prices on the Indonesian Sharia Stock Index but does not mediate the BI rate. This finding implies that the dynamics of global commodity prices and exchange rates should be the primary consideration in the investment strategy for Sharia stocks in Indonesia. In addition, the influence of the BI rate shows that the role of domestic monetary policy has also been proven to be significant in influencing the movement of the index.
