Using synthetic dyes for textile can be harmful human health and can cause environmental pollution. So, it needs a safe and environmental friendly to substitute of textile dye that is natural dyes. The advantage of natural dyes is a relatively low pollution and non-toxic. In addition, the use of natural dyes is in smoothness and softness of the color. This product is highly appreciated and maintained, because of its beauty, prestige, cultural structure that cannot replaced by synthetic dyes. One of organic waste and potential as a natural dyes for textile is a dragon fruit peel, because the dragon fruit peel was contained a lot of betacyanine pigment. It is required to substitute of safe and environmentally friendly textile dye that is natural dyes. This study was carried out to determine the effect of mass quantity of raw material, time extraction and different type of solvent to obtain an absorbance value. The mass of raw materials used is 1, 2 and 3 grams with the extraction time is 15, 30 and 45 minute. As for the solvent, is using water, acids and bases with a fixed volume. Natural dyes for textile can be made from materials that exist in the nature, as well as organic waste. The process is use several types of solvents such as water, acids and bases with a fixed volume. The result of natural dyes for textile indicates that, using a lot of mass of raw material and the longer extraction time will be resulti the highest absorbance value. The best type of the solvent to produce a high absorbance value is an alkaline solvent (base).
