One of the requirements of the batik textile industry is to use natural, safe, and environmentally friendly dyes. We researched different particle sizes and extraction temperatures to achieve the optimal chlorophyll concentration and mordant concentration for color durability and effectiveness. Before extraction, cassava leaves were dried and crushed to various sizes, i.e. 20, 40, and 60 mesh. Extraction temperatures were set to 30, 40, 50, 60, and 70 oC. Mordant concentrations were varied to 20, 30, and 40 gram/l, and were assessed as pre-mordanting, meta- mordanting, and post-mordanting. The chlorophyll concentration was measured using a UV-Vis spectrophotometer at a 645 nm and 665 nm wavelength. It was found that cassava leaves had the potential to become a natural dye for textiles because of their high chlorophyll concentration. The highest concentration was 16.001 mg/l, obtained from a simplicial size of 40 mesh and extraction temperature of 30 oC while the optimal result at a concentration of mordant 40 grams by using a meta-mordanting process.
