ABSTRACT
The ikat weaving industry plays a vital role in preserving cultural heritage while supporting the local economy. However, in its manufacturing process, the ikat weaving industry uses synthetic dyes that contain hazardous substances, resulting in negative environmental impacts, such as damage to aquatic ecosystems due to excessively high dye content. The aim of this study is to treat ikat weaving wastewater using biosorbent in the form of sugarcane bagasse obtained from the ikat weaving industry in Mojokerto Regency. This study used activated sugarcane bagasse with H2SO4 as an activator in a batch adsorption system as an alternative method. This study compares the efficiency of color removal in ikat weaving liquid waste with variations in biosorbent mass and contact time. The results of the study showed that the highest efficiency removal was found in the variation of adsorbent mass of 0.2 grams and contact time of 50 minutes, reaching 91.30%; The results of the statistical test analysis using the Two-way ANOVA model showed a value of Pr(>F) 0.681 for the adsorbent mass variable and Pr(>F) 0.555 for the contact time variable which indicated that both variables did not significantly affect the dye removal efficiency in ikat weaving wastewater.
