Sintesis Poly (Sodium Acrylate-co¬-Acrylamide) sebagai Flokulan Anionik pada Proses Pemurnian Nira

The problems in Indonesia related to the sugar industry is that sugar consumption is greater than its production which causes the inability of the sugar industry to meet the demands of all consumers. One of the problems that occur is due to the large number of imported raw materials including flocculants, which in this case is anionic polyacrylamide flocculants. Anionic polyacrylamide (APAM) was first developed in the world through an alkali hydrolysis process. So far, APAM synthesis technology has undergone a lot of development. In this study, synthesis poly (sodium acrylate-co-acrylamide) was performed as flocculant which will be used in the sugar refining process. The synthesis steps between acrylic acid and sodium carbonate. And then synthesis with acrylamide and add some of ammonium persulfate. This study was conducted in various concentrations of acrylic acid and acrylamide, i.e., 0: 100, 20:80, 40:60, 50:50, 60:40, 80:20, 100: 0. The resulting flocculants was tested in sugar canein in order to determine the effect of the flocculantsaddition. The result of FTIR test showed that the polymerization process between acrylic acid and acrylamide has been succeeded. After analysis, the most effective flocculants obtained at concentration acrylade: acrylamide of 50:50
