This paper discusses the mechanical properties of alternative wood substitute materials in the construction of small boats (jukung/cadik type). Jukung/cadik boat as a small fishing boat with a length overall 6,400 m, design beam 1,530 m, design draft 0.380 m, displacement 2,442 tons, wetted surface area 15.58 m2, the pressure acting on the submerged hull needed minimum material used has a strength of 0.0039 MPa or 3.92 kN/m2. The replacement material used is the HDPE blue drum scrap, which has an average thickness of 3mm, then made into two layers as laminate. The laminate process uses welding. The results of HDPE laminate material from these two layers are tested for tensile and compressive strength to meet the material strength requirements for small ship hulls. They were testing the strength of HDPE welded joints with type A1 specimens. Tension and compression of the two-layer laminate material was tested with specimens of type A2, A3, and A4. The tensile test results for A1 specimens obtained for welding tests are pretty good at 17.1 MPa, then the results of compression tests for specimen type A2, A3, and A4 on average are 23.36 MPa, which is greater than the need for the strength of the jukung/cadik hull.
