Abstract
This study aims to utilize wood sawdust waste in the paint industry waste treatment. The first thing to do is a qualitative analysis of heavy metals before and after the processing. Furthermore, the parameters measured are temperature, pH, TDS, and dissolved oxygen (Dislove Oxgen). The use of wood sawdust as a heavy metal adsorbent in paint industry wastes is able to provide efficient results with no sediment formation when conducting qualitative analysis of Cu2+ and Cd2+ metal ions and raising the waste parameters to be environmentally friendly. This is indicated by the decrease in TDS, COD, Cu and Cd levels, namely before the adsorption levels were 672 mg / L, 320 mg / L, 2.07 mg / L, and 0.23 mg / L, respectively. After adsorption the levels were 348 mg / L, 120 mg / L, 0.08 mg / L, respectively, and for Cd it was undetectable.This shows that the adsorption process works optimally.
