This study seeks to examine and assess the influence of Zakat, Infaq, and Sedekah (ZIS), corruption, and education on income inequality in Indonesia. The research uses a saturated sampling method, collecting data from the National Zakat Amil Agency (BAZNAS), Transparency International, the Central Statistics Agency (BPS), and the World Bank. The analysis uses quantitative time-series data from 2011 to 2022, processed with Stata 15, and employs multiple linear regression as the analytical method. The results indicate that ZIS has a significant negative effect on income inequality, while corruption also significantly reduces income inequality. On the other hand, education shows a positive but statistically insignificant effect. The coefficient of determination test reveals that 93.06% of the variation in income inequality can be explained by ZIS, corruption, and education, with the remaining 6.94% attributed to other factors not included in the study. Additionally, the findings suggest that ZIS and corruption together have a notable influence on income inequality.

This study focuses on examining the impact of halal certification, product quality, and marketing strategy on the sales of Home Industry food products. A descriptive quantitative approach was adopted to analyze the relationship between variables. Data were collected through questionnaires distributed to 170 respondents who were food product business actors Home Industry in Sariwangi District, Tasikmalaya Regency, West Java Province. The collected data were analyzed using the Structural Equation Modeling method with a Partial Least Squares (PLS-SEM) approach. The results show that both halal certification and marketing strategy have a significant positive effect on sales of Home Industry food products. Meanwhile, product quality does not show a significant effect on sales. The study also indicates that halal certification has the strongest influence on sales compared to the other variables.
