Abstract

The development of technology causes most of textile industries in Indonesia prefer to use synthetic dyes in the fabric dyeing process. In fact, synthetic dyes is able to have negative effect since it is is toxic to the health of workers and environment. To resolve this issues, one way to do is to use natural dyes. One of untapped potential in Indonesia is wood waste of jackfruit from furniture industry. Jackfruit wood itself containing dyestuffs which gives yellow color pigment so that it can be used as an alternative source of natural dyes. The purpose of this research is to study the effect of extraction time, mass to solvent volume ratio, and microwave power to yield of dyes. The extract of dye analyzed by UV-Visible Spectrophotometer and GC-MS, along the coloring and endurance tests of natural dyes on fabric and compare it with synthetic dyes. In this research, material is going to be extracted is the wood of jackfruit (Artocarpus heterophyllus lamk) with material size between 35 mesh - 60 mesh. The extraction process is done by using ethanol 96%. Extraction using MAE is carried out at the ratio of materials to solvent of 0,02-0,1 g/mL, the microwave power of 100-800 Watt, and the extraction time of 10-90 minutes. The conclusion is at microwave power of 400 Watt, material to solvent ratio of the 0,02 g/mL, the yield is 3,39% while at microwave power of 600 Watt, material to solvent ratio of the 0,02 g/mL, the yield is 3,67% with extraction time of 30 minutes. The highest recovery from ethanol 96% solvent is 60,41%. The result of UV-Vis Spectrophotometry and GC-MS test show that there is a chromophore compound in the extract of natural dye. The test results show the natural dyes of jackfruit wood can be used to coloring on the textile because it can gives staining result permanently.
