The growth of weeds as"undesirable"plant needs to be controlled. The main controller for weed removal is pesticides. However, pesticides cause pollution towards soil, water, air, and human. Alternatives are needed in controlling weeds. The weed to be experimented with is Lorotis weed (Aeschynomene Indica). The independent variables in this study were quicklime mordant, lime mordant, and iron sulfate mordant. The dependent variable is color aging and color fastness to washing. The control variables in this study were 1 kg of lorotis weed, 5 liters of water, 1.5 m of primishima mori, 10 minutes of mordant generation with a ratio of 250 grams of mordant: 2.5 liters of water, 10 minutes of immersion, 15 times the sample frequency. Results of the study showed that Lorotis weed has the potential to be used as a textile dye. Textile dyeing process needs to be supported by mordanting process. Iron sulfate mordant is proven to produce color with the highest level of color intensity. While the color fastness test showed that quicklime mordant has a good fastness level. © 2023 Author(s).
