MadaABSTRACTChitosan has been used as biosorbent. In addition to having advantage chitosan as biosorbent has also disadvantage. Chitosan is very soluble in low pH so it cannot adsorb Cr (total) atlow pH. It is due to active site (amine group) of chitosan undergo protonation and its adsorption capability is easily influenced by anions in waters. Therefore, the research studied use of chitosan coating active charcoal of coconut shell to increase adsorption capability of Cr (total), BOD, COD. This research was done to evaluate characteristic of liquid waste quality with Wastewater treatment unit (IPAL) or without Wastewater treatment unit (IPAL) and compare with Regulation of DIY Governor number 7/2010. It studied also effect of pH and Concentration of chitosan coating active charcoal as adsorbent on decrease in Cr (total), BOD, and COD concentration on liquid waste of leather tanning. The results indicate liquid waste of leather tanning industry with Wastewater treatment unit (IPAL) and without Wastewater treatment unit (IPAL) have exceeded quality standard of liquid waste of leather tanning industry. ANOVA statistical test indicated Cr (total), BOD, COD are significant at 0,05 (p
