Abstract

The discharge of batik dye effluents into water bodies is a significant environmental concern, as it contains toxic azo dyes that are difficult to degrade. Traditional methods for dye removal, such as chemical oxidation and adsorption, often have limitations in terms of cost, efficiency, and environmental impact. This study aims to investigate the photocatalytic degradation of batik dye effluents using zinc oxide (ZnO) nanorods synthesized through a green chemistry approach. ZnO nanorods were synthesized using natural plant extracts as reducing agents, offering an environmentally friendly and cost-effective alternative to conventional methods. The photocatalytic performance of the synthesized ZnO nanorods was evaluated by exposing them to batik dye effluents under UV light. The effects of parameters such as pH, catalyst dosage, and UV exposure time were studied. The results showed that ZnO nanorods exhibited significant degradation of the dye, with optimal performance achieved at pH 5, a catalyst dosage of 0.2 g, and 120 minutes of UV exposure. The nanorods demonstrated high reusability, making them suitable for long-term application in wastewater treatment. This study highlights the potential of ZnO nanorods synthesized via green chemistry as an efficient, eco-friendly solution for treating batik dye effluents, offering a sustainable alternative to traditional wastewater treatment methods.

Abstract

Background. Non-formal education plays a significant role in rural South Africa, where formal education systems often face challenges such as limited infrastructure and financial resources. The integration of technology can help bridge these gaps, offering innovative ways to deliver education in under-resourced areas. Purpose. This study aims to explore the role of technology in enhancing non-formal education in rural South Africa, particularly focusing on its effectiveness in improving access, quality, and engagement for learners. Method. A qualitative research approach was employed, with interviews and focus group discussions conducted among educators, students, and community members in rural areas. Results. The findings reveal that technology, particularly mobile learning platforms and digital resources, has significantly enhanced accessibility to educational materials. Additionally, it has contributed to more interactive and engaging learning experiences, though challenges such as unreliable internet connectivity and limited technological skills among educators persist. Conclusion.  The study concludes that while technology has great potential to improve non-formal education in rural South Africa, efforts must be made to address the challenges of infrastructure and digital literacy.
