| description | Problems that are often encountered in the results of the development of material modificationsuper absorbent polymers (SAPs) in the form of water absorption ability and ability swelling which is low, solubility in water and organic compounds is lacking, the condition of the material is hard and brittle and not environmentally friendly so it is difficult to decompose. These conditions can be minimized and improved through modification of monomer compounds, crosslinker, and initiator in the polymerization process. The polymerization process is carried out by the method chemical crosslinker with crosslink agent i.e., formaldehyde in the main chain (backbone) namely polyvinyl alcohol (PVA) and daughter chains namely bagasse cellulose with the help of an initiator in the form of potassium persulfate (KPS). The results of the study showed that formation of a new functional group (C-OH stretch) at 1143,30 cm-1; (-OH) at 3461.03 cm-1; (C-O-C) at 1200,55 cm-1; (C=O) at 1529.86 cm-1. The highest absorption capacity reached 746.4912% in the sample with 0.8 gram of initiator and crosslink 0.8mL. Mark Swelling the highest was obtained in acidic conditions, namely pH 6 with a value of 358.3007. The surface morphology of the superabsorbent is formed with pores ± 11.7537 nm which is a dense, strong and elastic surface. The surface change proves that the process grafting and interactions interfacial two materials going well.
