Abstract

Online learning is one of the implementations of distance education that continues to develop, particularly with the utilization of video conferencing applications such as Zoom Meeting. This study aims to analyze the effectiveness of using Zoom Meeting in online learning by focusing on detecting students' attention levels based on blink analysis. In this research, an eye detection module was developed using the Dlib Model and Facelandmark, with the Histogram of Oriented Gradients (HOG) method as a feature extraction technique. Blink analysis was conducted to determine the blink ratio, which serves as an indicator of an individual's attention level. Generally, attention levels can be identified through blinking patterns, where fatigue or lack of focus is reflected in higher blink frequency. The study results show that the developed system can identify an individual's focus level with a highest accuracy of 95.56% in tests with three subjects, while the lowest accuracy was 72.24% in tests with 16 subjects. Based on the analysis of blink frequency during learning sessions using Zoom Meeting, it can be concluded that the average student focus level remains within the normal range.

Abstract

Economic growth is an important indicator in assessing the success of a country’s development. Although the development of the Islamic capital market and inflation has been widely studied, research that specifically analyzes the effect of the market capitalization of Sharia stocks included in the Indonesian Sharia Stock Index (ISSI) and inflation on Indonesia’s economic growth during the 2021–2024 economic recovery period remains relatively limited. This study aims to analyze the effect of ISSI Sharia stock market capitalization and inflation on Indonesia’s economic growth, both partially and simultaneously. This study used a quantitative approach with a causal associative design. The research sample covered all quarterly data for the 2021–2024 period, selected through saturated sampling. Data were collected through documentation from official publications of Statistics Indonesia, Bank Indonesia, the Indonesia Stock Exchange, and the Financial Services Authority, and were then analyzed using multiple linear regression. The results showed that ISSI Sharia stock market capitalization had a positive and significant effect on Indonesia’s economic growth, with a significance value of 0.002. Inflation also had a positive and significant effect on economic growth, with a significance value of 0.000. Simultaneously, the two variables had a significant effect on economic growth, with a significance value of 0.000 and an Adjusted R² value of 0.741. These findings strengthen Keynesian Growth Theory, which emphasizes the importance of investment in driving economic growth, and broaden understanding of the role of the Islamic capital market and macroeconomic stability in national development. The conclusion of this study confirms that ISSI Sharia stock market capitalization and inflation are important factors contributing to Indonesia’s economic growth during the economic recovery period. The implications of this study point to the importance of strengthening the Islamic capital market and controlling inflation to support sustainable economic growth.
