Improper processing of plastic waste can cause several environmental problems, such as air pollution, soil damage, respiratory diseases, and others. This research utilizes high density polyethylene (HDPE) waste as a basic material for synthetic beams. The manufacture of synthetic beams goes through several stages, such as washing, drying, crushing, chopping, and melting HDPE waste, as well as moulding into a block. The physical properties examined in this study include compressive strength, flexural strength, density, and ductility which refer to SNI 03-3958-1995 and SNI 03-3959-1995 codes. From the test results, it was obtained that the average compressive strength and flexural strength of synthetic beams were 1.52 – 2.53 MPa and 0.61 – 0.95 MPa, respectively. Synthetic beams have an average modulus of elasticity of 109.4 MPa, and a density of 834.8 kg/m3. The test results from this study indicate that the strength of synthetic beams from HDPE is low and does not meet the requirements for use as a construction material. In further research, innovation is needed to obtain stronger synthetic beams.
