The batik industry faces challenges in developing products that are not only aesthetically pleasing but also have added value that is environmentally friendly and functional. This research aims to optimize the use of zinc oxide (ZnO) nanoparticles in batik fabrics in an effort to achieve sustainable antibacterial effects. ZnO nanoparticles are known for their strong antimicrobial properties and stability, making them suitable for application in textiles. This research method involves the synthesis of ZnO nanoparticles via a sol-gel technique and their application to basic fabrics through a pad-dry-cure process. Antibacterial activity tests were carried out on Escherichia coli and Staphylococcus aureus via the agar diffusion method. The results showed that the basic fabrics optimized with ZnO had significant inhibitory zones against both types of bacteria, indicating a strong antibacterial effect. Antibacterial activity was tested against Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive) via the agar diffusion method. ZnO-coated fabrics demonstrated strong inhibition zones of 15 mm for E. coli and 18 mm for S. aureus, confirming their effectiveness as antibacterial agents. Durability testing through ten washing cycles showed only a moderate decrease in antibacterial activity, with inhibition zones reduced to 13 mm and 16 mm, respectively, indicating strong binding stability. The sustainability of this effect was tested through many washing simulations, where the antibacterial activity of batik fabric was still retained. This research opens up opportunities for the batik industry to adopt green innovations that can increase selling value and expand the market while contributing to environmental conservation efforts. These findings open opportunities for the batik industry to strengthen competitiveness, increase product value, and contribute to sustainable textile development aligned with global demands for health, culture, and environmental responsibility.
