Abstract

Polbeng 1 Research Vessel was built in 2025 at the Politeknik Negeri Bengkalis and in collaboration with CV Fatih Bahari Engineering. This vessel is made entirely of high-density polyethylene (HDPE) plastic. This ship is assembled using a welding method carried out using X-groove welding. However, there are several theories that state that V-groove joints are better. So validation is needed on the strength of the Polbeng 1 Research Ship construction. The first validation was carried out by conducting tensile tests and bending tests; the standards used were ASTM D638 and ISO 527–2. The test results showed that the X joint had better strength compared to the strength of the V-groove with a reduction in tensile strength of the unwelded material of 24.3% and 26.8%, respectively. The bending strength also decreased by 11.35%. And 63.8%. The second validation was carried out by calculating the pressure on the shell bottom (P_dBM) from the formula in the Biro Klasifikasi Indonesia 2021 regarding Classification and Construction Rules. The calculation results showed that the X-groove connection met the standards of the Biro Klasifikasi Indonesia (BKI).
