The pigment paste variations in the composites were 0%, 5%, 7,5%, and 10%, with immersion durations of 0, 2, 4, 6, 8, 10, 12, and 14 weeks on a laboratory scale. All pigment addition variations and immersion durations in the composites were subjected to tensile testing. Fourier Transform Infrared (FTIR) and Scanning Electron Microscope (SEM) analyses were also performed to examine the functional groups present in the composites and the morphology of the fracture surfaces from the tensile tests. The research results show that the effect of adding pigment pastes on tensile strength at variations of 0%, 5%, 7,5%, and 10% decreased compared to the normal sample values by 2,04%, 9,96%, 8,75%, and 10,0,4%, respectively, at week 14. ## Keywords - Ultimate tensile strength - Materials science - Ramie - Composite material - Composite number - Scanning electron microscope - Pigment - Seawater - Tensile testing - Optical microscope - Fourier transform infrared spectroscopy - Immersion (mathematics) - Fractography - Artificial seawater --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
