N2 - One alternative to reduce the effect of water pollution from the textile industry is to replace the use of synthetic dye with the natural one. Henna leaves are one of the natural dye sources which has lawsone, a unique substance that produces orange colour. Some commonly used conventional extractions are soxhletation and maceration. One extraction method that is tried to be developed in this study is the Ultrasound-assisted Extraction. The effects of feed ratio to solvent, time, temperature and solvent types were investigated and discussed in this study. The highest yield from the extraction of Henna leaves was found to be 17.96% which was achieved at pH 1 with the extraction time of 10 minutes, feed/solvent ratio of 0.02, and aquadest solvent. Based on the both qualitative and quantitative analysis of the extracted colour, the ultrasound assisted method was found to be more effective and efficient than the soxhletation method.
