The using of plastic waste from various types of plastics such as polypropylene and LDPE is carried out to see the properties of each biodegradable plastic produced, so that it can be used according to their respective needs. The addition of starch from empty fruit bunch of palm oil is expected to produce biodegradable plastic that breaks down naturally so that it can overcome the problem of plastic build up. The composition used in the manufacture of biodegradable plastics is the ratio of plastic waste and starch of empty fruit bunch of palm oil is 60:40. The method of molding biodegradable plastics is the hot press method. Biodegradable plastic from LDPE type plastic waste has a tensile strength price of 6.9410 N/m 2 and a elongation value of 3.1875%, a melting point temperature of 103°C and a decomposition temperature of 384°C, the gravimetric thermal test obtained a residue of 12.6%, and analysis of morphological properties shows spread the starch from empty fruit bunch palm oil evenly. Biodegradable plastic from polypropylene type plastic waste has a tensile strength value of 9.81 N/m 2 and elongation of 0.5625%, a melting point at a temperature of 163.68°C and decomposes at a temperature of 445.62°C the gravimetric thermal test obtained a residue of 11.5%. From the resulting characteristics, it can be concluded that biodegradable plastic made from LDPE material has lower strength but higher elasticity, and biodegradable plastic made from Polypropylene has better strength but low elasticity.
