Areca nut fiber contains pectin, pectin oksalat, and flavonoids that can act as antibacterial. The content of coir nut compound can inhibit the growth of P. aeruginosa bacteria causing wound infection and burns. The objectives of the study were to measure and analyze ethanol extract concentration of 2% b/v, 3% b/v, 4% b/v, 5% b/v, and 6% b/v concentration in inhibiting the growth of P. aeruginosa bacteria. The research stages started with P. aeruginosa bacteria certification, making nutmeg extract with maseration method for 48 hours (2x24 hours) using 96% ethanol, then testing method using diffusion well. The results showed that 2% b/v, 3% b/v, 4% b/v, 5% b/v, and 6% b/v ethanol extract concentrations were able to inhibit P. aeruginosa bacteria with consecutive inhibit zones 15.2 mm, 16.6 mm, 17.4 mm, 18.4, and 19.2 mm, respectively. Result of Kruskall-wallis test with significant value p = 0,247, showed no significant difference between ethanol extract concentration of areca nut to P. aeruginosa bacteria growth.
