| dc.description.abstract | Oil palm (Elaeis guineensis Jacq) is a plantation crop that has developed quite well in Indonesia. In addition to high palm oil production, this also affects palm oil by products or waste. One example of palm oil waste is palm shells. Oil palm shell waste can be used as a natural dye because oil palm shells contain flavonoid compounds. This research is expected to provide information related to the utilization of palm oil waste, especially shells, to become natural dyes and to determine the value of the dye test on linen fabric media for two treatment factors, namely particle size (micro and nano) and cloth soaking time (12 hours and 24 hours), the patterns used in the coloring of the cloth are sikkam leaves and noni leaves. Fastness testing of ecoprint results is carried out by washing and drying under direct sunlight. The average particle size produced in micro samples is 3,94 μm with a standard error of 0,88 and in the nano samples it is 25 nm with a standard error of 0,59. Micro sample yield was 6,67%, while nano sample yield was 8,04%. The control had the lowest dye retention value of 7,81%, while the nano sample size with 24 hour immersion had the highest retention value of 18,47%. The nano sample produces a darker color than the micro sample, but the immersion time does not show a significant difference. The value of the difference in the color of the oil palm shells with the difference in particle size after the fastness test was carried out have the same level of color difference in the small category (ΔE = 2 – 3,5) This is suspected even though they have different partcle sizes, but the phytocemical content is the same so that th color changes are not so different after the fastness test. | en_US |
