Abstract

Natural dyes are used as a non-biodegradable alternative to synthetic dyes. Fresh palm fruit bunches (FFB) are known to contain several compounds which are thought to be used as alternative natural dyes, such as: flavonoids, caratenoids and tannins. Apart from that, the use of industrial waste is an added value in this research. Fixation is the most important stage after the color dyeing process because fixation is a stage to lock and strengthen the direction of the color. The types of fixator used in this research were tawas, kapur, and tunjung. The aim of this research is to see whether CPO production sterilizer waste can be used as an alternative to natural dyes and how the type of fixator affects the dyeing results of silk fabric. The evaluation parameters of the dyeing results observed were the value of color maturity, color evenness, and washing and rubbing fastness. The results showed that the three types of fixator had an effect on the color aging value produced but did not have a significant effect on the fastness of washing and scrubbing. The highest K/S value was found in Tunjung mordant at 1.33 at ʎmax 400nm. Meanwhile for Kapur and Tawas mordant it is 0.72 and 0.71. Keywords: fixator, natural dyes, waste

Abstract

One of the companies that make tools for printing at one of the printing companies in Jakarta has a product in the form of Offset Roller Printing, where Offset Roller Printing is a mainstay product with the highest sales. The company promises a declining trend in the rejection rate in 2024, with the rejection rate not exceeding 2%. For that, an analysis of the cause of the problem will be carried out until a repair proposal is obtained by using an integrated method which is Statistical Quality Control (SQC) with Failure Mode Effect Analysis (FMEA). Based on the check sheet, it shows the total production in January - December 2023 of 5699. On the overall operational map, there is no point that is outside the upper or lower operational limits. From the results of the FMEA analysis, it can be seen that the highest RPN is the cover for the method factor with the first priority having an RPN value of 252 which means that the vulcanization temperature is not reached or the temperature of the maturity point is not reached. unable to. There is a need to renew the vulcanization recipe so that the rubber matures perfectly and avoids the occurrence of oblong or closed defects. In addition, improvement proposals as a form of evaluation results are given related to the operator's attention factor, operator's skill, various types of materials, working environment temperature, no machine control, comfortable work environment, hostap plastic setting.
