Adsorben is one of the alternative media for processing waste water. The aim of our study is to reduce metal ions content that were Fe(III) dan Cu(II) in the laboratory liquid waste by using of cocoa pods husk M45 (Theobroma Cacao) as a biosorbent. This research was carried out through two systems, that were batch and continuous systems. Batch system was conducted to determine optimum contact time, pH optimum, and adsorption capacity, whereas continuous sytem was intended to determine adsorbent height and the maximum flow rate of laboratory liquid waste. The methods used in this study were adsorption and filtration. The adsorption results were analyzed by AAS (Atomic Absorption Spectrophotometer). Study results found that the optimum conditions of cocoa pods husk M45 (Theobroma Cacao) adsorption for metal ions content, Fe(III) dan Cu(II) were for 90 minutes and at pH of 6 in the system batch. The optimum flow rate of the continuous system was at 6.166 mL/sekon with an adsorbent height of 15 cm in the 2 inch adsorption column. The adsorption capacity of adsorbent for Fe(III) metal ion was at 11.074 mg/g and 28.4091 mg/g for Cu(II), respectively based on the Langmuir isothermal method.
