Abstract

The use of plastic materials in agriculture causes the serious drawback of huge quantities of waste. The introduction of biodegradable materials, which can be disposed directly into the soil, can be one possible solution to this problem. Biodegradable materials are actually innovative materials; therefore, their physical properties must be evaluated in relation to their functionality during the use in field. In this research, Sago starch is physically mixed with different composition of Glycerol to produce Strength Sago Starch Film. Glycerol was added to the sago starch gel as a plasticizer to modify the mechanical properties and thermal properties of sago starch film. Deterioration in properties for Tensile strength (TS) but improvement on elongation properties of sago starch film with increasing amount of Glycerol was found. Additives such as Aldehyde and microcrystalline cellulose (MCC) were added to improve strength of Sago starch/Glycerol film. Characterisation made using Differential Scanning Calorimetric (DSC) showed significant differences between their melting or gelation transition while scanned with a Fourier Transform Infra Red (FTIR) Spectra showed strong absorption of carbonyl Aldehyde group. 40% to 60% Glycerol content were found to give optimum strength for sago starch film. All the experiments and tests were conducted at Lab Polymer 411,410 and 112 and Lab Applied Chemistry 307 at Applied Science Faculty, UiTM Shah Alam, Selangor.
