Pengaruh Suhu Pemanasan Ekstrak Rumput Laut Coklat (Sargasum Plagyophyllum) Sebagai Antibakteri Staphylococcus Aureus Dan Pseudomonas Aeruginoosa
Abstract
This study aimed to determine the effect of different temperatures on the effectiveness of
brown seaweed extract (Sargasum plagyophyllum) as an antibacterial agents for Staphylococcus
aureus and Pseudomonas aeruginoosa. The treatment conducted was heating the extract with
varied temperatures (50, 60 and 70 ºC). The parameters assessed were the clear zone diameter on
each medium for Staphylococcus aureus and Pseudomonas aeruginosa bacteria. The results
showed that the extracting the brown seaweed at the temperature of 70 ºC was the most effective
treatment to inhibit the growth of Staphylococcus aureus and Pseudomonas aeruginosa bacteria
with an inhibition zone diameter of 4.31 mm of 8.30 mm, respectively.
Keywords: antibacterial, Pseudomonas aeruginoosa, Sargasum plagyophyllum and
