Effectiveness of Activated Carbon from Cassava Peel Waste to Reduce TSS (Total Solid Suspended) Levels in Batik Liquid Waste

Abstract

The results of the first trials show that the TSS content in Batik liquid waste in Pati is quite high at 540.75 mg/L. The study aims to determine the effect of making adsorbents from cassava peel waste which is influenced by the activation of adsorbents on TSS absorption in batik liquid waste. This research method includes the steps of making activated carbon from cassava peel waste, the process of activation of chemical carbon, and the adsorption test of batik liquid waste. Varied variables are for HCl, NaOH and without activators. The results showed a decrease in TSS for activator HCl 282.135 mg/L, NaOH activator 352.375 mg/L and without activator 386.245 mg/L. Based on research, the adsorbent from cassava skin is good for reducing TSS in batik liquid waste. Carbon activation with activator HCl is the most effective in absorbing TSS content in Batik liquid waste.

A Review on Cassava Residues as Adsorbents for Removal of Organic and Inorganic Contaminants in Water and Wastewater

“…0.1 M sodium hydroxide was found to be an efective activating agent for cassava bark residue to remove methylene blue dye. Tri Widayati et al [82] studied the removal of the total suspended solid present in batik liquid waste by using inactivated cassava peel carbon and activating carbon by 0.1 M hydrochloric acid and 1.0 M sodium hydroxide. Tey observed a decrease in the total suspended solid for the activating agent (hydrochloric acid) with an adsorption percentage of 47.83%, whereas with the activating agent (sodium hydroxide), the percentage of adsorption was 34.84%, and then, without the activating agent, the percentage of adsorption was found to be 28.57%.…”
