Antifouling paint was introduced and utilized as a control to prevent the problem of biofouling. The Methanolic Crude Extract (MCE) Essential Oil (EO) were extracted from Melaleuca cajuputi. Gas Chromatography-Mass Spectrometry (GC-MS) used determine metabolite profiles. An antibacterial assay conducted via disc diffusion technique an antifouling MCE EO M. cajuputi investigated using crystal violet painted steel panels incorporating EO. Painted immersed in aquarium measure antibiofilm activity natural sea environment observe settlement foulers. exhibits against Gram-negative bacteria, indicating narrow-spectrum activity, while has broad-spectrum Gram-positive −negative bacteria. GC-MS profile showed presence cycloheptasiloxane, tetradecamethyl-, cyclotrisiloxane, hexamethyl-, terpinene-4-ol, caryophyllene, 1,8-cineole both Crystal revealed that samples reduced attachment biofilm form by Pseudomonas aeruginosa at 61% 60%. Panel with incorporated 5% inhibits bacteria growth seawater, followed 10% MCE, EO, testing. Referring photographic observation, all coated successfully foulers compared Blank Paint (BP). In conclusion, these findings indicated could potentially be substitute for toxic antifoulants formation microfoulers.
