Abstract

Textile liquid waste containing various chemicals and pollutants is a serious problem because it is difficult to achieve waste water quality standards in accordance with Minister of Health Regulation No. 416/1990. This research uses a literature review method to analyze various studies related to the use of activated charcoal in treating industrial liquid waste. Activated charcoal, with a carbon composition of 85-95%, is known to have high adsorption capabilities thanks to its porosity which can reach hundreds to thousands of square meters per gram. The process of making activated charcoal involves carbonization and activation of carbon materials at high temperatures. The method used was a review of articles between 2015 and 2023. The research results showed that activated charcoal was effective in reducing Chemical Oxygen Demand (COD) by up to 98.74%, which indicates a significant reduction in pollutant content. The adsorption process, which is an exothermic reaction, occurs more efficiently at low temperatures and increases with the length of contact time between activated charcoal and liquid waste. Conclusion: Textile industry liquid waste and variations in activated charcoal dosage and shaking time provide concrete data on the efficiency of activated charcoal in dealing with water pollution, offering a sustainable solution for industrial liquid waste management.

Abstract

The use of natural dyes as an environmentally friendly alternative to reduce the use of synthetic dyes which have a negative impact on the environment. Natural dyes can be obtained from various natural sources such as plants, animal waste, and minerals, with plants being the most common source. Plant pigments such as anthocyanins, tannins, flavonoids, and chlorophyll provide a variety of colors that can be used for coloring. The natural dyeing process involves four stages: making the dye solution, fabric preparation, dyeing, and fixation. Testing the quality of natural dyes includes color visualization tests, color aging, color differences and fastness to washing. The methodology for writing this article is a literature study, reviewing various related research from 2013 to 2023. The results show that several plants such as Tarum, Coconut, Secang, Noni, Turmeric, and Shallots can produce colors such as dark blue, brownish cream, red , yellow, and brownish orange on fabric. In conclusion, natural dyes not only support environmental sustainability but also offer a safe and low-cost coloring alternative, although there are challenges in the manufacturing and application process of these natural dyes.
