In the light of finding solutions to the adversity brought by non-biodegradable wastes, bioplastic a polymer derived from renewable biomass resources such as starch, cellulose and lignin was discovered. Starch from rambutan (Nephelium lappaceum) was used as a raw material to determine its potential in bioplastic production. Rambutan seed starch plasticized with sorbitol was developed and characterized. The starch, sorbitol, vinegar and water were prepared in the ratio of 30g: 5ml: 5ml: 60ml. The characteristics of the starch in terms of ash content, moisture content and starch content was determined. From the analysis of rambutan seed starch, the ash content of 1.33%, moisture content of 79.6% and starch content of 22.83% were obtained. Soil burial test was conducted in determining the biodegradability of the film produced. The mass of bioplastic was reduced by more than 50% in the first 6 days and complete degradation occurred on the 15th day. Nephelium lappaceum seed is of good quality based on the low ash content but has high moisture content and even with the presence of starch the bioplastic film that was formed needs further investigation.
