dc.description.abstractTo improve properties of superabsorbent polymer (PSA) synthesized from onggok (cassava residual pulp), we have grafted binary monomer mixture of acrylic acid and acrylamide onto onggok in aqueous medium using APS as initiator. Some factors of the synthesis studied were loading sequence of monomer, addition of cross-linker, and absorption capacity. Testing was also performed by infrared spectroscopy. The PSA A1, which is created by grafting of acrylic acid and acrylamide without cross-linker, showed the highest water absorption of 370 g/g. The PSA A1 effectively absorbed water at pH 9 and the absorption capabilities were affected by levels of salinity of the medium. The PSA also potential as Cu2+ metal ion adsorbent.en
