Abstract

This study investigates the effect of using rice husk charcoal as an adsorbent in adsorption-assisted distillation for bioethanol purification. The research is motivated by the need for more efficient, low-cost, and sustainable bioethanol purification methods, considering the limitations of conventional distillation due to azeotrope formation and high energy consumption. An experimental laboratory method was employed by varying the mass of rice husk charcoal at 3 g, 5 g, and 7 g under a constant operating temperature of 78 °C and an initial ethanol concentration of 70%. Performance parameters analyzed included ethanol concentration improvement, separation efficiency, bioethanol yield, and condenser performance. The results indicate that increasing adsorbent mass significantly enhances ethanol purity, with the highest concentration of 89.4% and maximum separation efficiency achieved at 7 g of adsorbent. However, the highest bioethanol yield was obtained at 3 g of adsorbent, indicating a trade-off between product purity and quantity. Overall, rice husk charcoal is proven to be an effective, environmentally friendly alternative adsorbent with strong potential for application in small- to medium-scale bioethanol purification systems.

Abstract

This study systematically examines the role of zakat in promoting sustainable finance and achieving Sustainable Development Goals (SDGs). Through the Systematic Literature Review (SLR) method, this study identifies, analyzes, and synthesizes various empirical studies and national data related to zakat’s contribution to economic, social, and environmental development. Zakat, as an Islamic social finance instrument, has great potential in strengthening the inclusive financial ecosystem and supporting community welfare. The literature review shows that zakat plays a significant role not only as a financial instrument for redistributing prosperity but also as a catalyst for sustainable development through environmental conservation, economic empowerment, enhanced social resilience, and increased financial inclusion. The integration of zakat into the sustainable finance policy framework has been proven to support the achievement of several SDGs, particularly the goals of poverty eradication (SDG 1), decent work and economic growth (SDG 8), and inequality reduction (SDG 10). Therefore, zakat’s potential can be optimized through good governance, digital innovation, and cross-sector collaboration is a strategic key to accelerate the realization of sustainable finance and achieve the SDGs in Indonesia
