Abstract
The Chromium(VI) waste treatment system in the textile industry activities in Indonesia is an environmental problem that really needs attention. This is because Chromium(VI) is a heavy metal that falls into the category of hazardous and toxic materials. So that it can have a negative impact on the environment and health of the body. One simple processing effort to reduce the amount of Chromium(VI) in waste is the biosorption method using organic adsorbents. One of these organic adsorbents is Salacca zalacca seeds. Salacca zalacca seeds can be used as an alternative adsorbent because they have cellulose fibers that can adsorb Chromium(VI) ions in waste. This research was conducted using a sample of clothing coloring waste obtained from one of the textile engineering schools in Bandung, Indonesia. In addition, research was also conducted on determining the right dosage so that the adsorption results were maximal. The results showed that Salacca zalacca seed powder was able to adsorb as much as 76.21% of the amount of Chromium(VI) in 100 mL of waste samples with a dose of 4 grams. These results indicate the level of effectiveness and proper absorption of powdered Salacca zalacca seeds. So that this method can be used as an alternative method to treat Chromium(VI) waste in a simpler and cheaper way.
