Abstract


Plastic has become one the most influential material in human lives due to it being light and strong enough. However, because plastic is non-degradable, it will cause other environmental problem and it is not renewable. Therefore a material that can produce plastic, where it could easily be degradable and the source is renewable. One of these materials is Polylactid acid (PLA) which is derived from starchy plants, such as cassava. However the physical and mechanical of pure PLA still has its downsides, such as low attraction and limited thermal degradation. This research is focused on synthesis PLA from local cassava and addition local clay into PLA in order to improve the two characteristics mentioned previously. The results that the highest was obtain 1,9 kg for 6 hours of disposition and the highest lactic acid obtained 35 % for 5 days fermentation. Polymerization PLA from a lactic acid has been determined by FTIR results. Based on the data show PLA/clay 0,05 M with 2 hours has better tensile strenght is 36 MPa and thermal stability compared to pure PLA to be applied as the raw material for packaging.
