The screen printing home industry generates wastewater causing dangerous environmental pollution since it has heavy metal contents. Cassava peel is one material that can be activated and used as an adsorbent to treat the wastewater. This study aims to analyze the effect of mixing speed on dye adsorption using cassava peel waste in a batch reactor and mixed by the jar test device. In the process of making adsorbents, cassava peel was dried and carbonized in a furnace into a powder, and then it was activated using H 2 SO 4 solution. Wastewater was contacted with the 10 gr of adsorbent then mixed in variation speed of 50, 100, 150, 200, 250 rpm and variation contact time of 30, 60, 90,120, 150 minutes. The maximum removal of 96.78% was observed in the mixing speed of 100 rpm over the 60 minute contact time. It could be concluded that organic waste such as cassava peel is a great adsorbent and resolves color pollution in the environment.
