Abstract
Metroxylon Sagu or also known as Sago starch, is one of local materials found in abundant in Sarawak. In this study of developing the sago starch-based thin film, Titanium Oxide (TiO2) as the main catalyst to be infused within the thin film, and was used to treat sago wastewater The developed films were characterised using surface morphology scanning electron microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) to analyse the pattern or image developed by the film under the beam light. Based on the characterisation of SEM, the structures formed on the surface of the film are nearly identical for each sample and the distribution of Titanium Oxide (TiO2) are uniform. For FTIR analysis, both of the plasticizers have the same functional groups and compound only that glycerol contain higher intensity in the hydroxyl group due to stronger and wider hydrogen bond between the molecules. Analysis of wastewater in terms of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS) against the function of time were also completed. The photocatalysis reaction between UV light with power of 40 watts and Sunlight were compared and it shows that the reaction under UV light showed better photocatalysis reaction compared to Sunlight due to the different intensity. For the comparison between plasticizers, sorbitol showed better photocatalysis reaction compared to glycerol. For the reaction of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS) against the function of time with sorbitol, the readings of the degradation are 2% better compared to glycerol as the plasticizers. Overall, it shows that sorbitol are slightly better as the plasticizers to be used in order to treat sago wastewater via photocatalysis reaction.
