Abstract

Eucheuma spinosum, red algae, contains secondary metabolites that act as antibacterial. It can be used as an active compound in the production of alcohol-free hand sanitizer. This research was aimed to determine the gram-positive and gram-negative antibacterial activity, pH, and viscosity of alcohol-free hand sanitizer containing E. spinosum extract. The results showed that the alcohol-free hand sanitizer containing 8% E. spinosum extract had characteristics in the form of a gel with the antibacterial activity of gram-positive bacteria (Bacillus subtilis) of 8.83±0.76 mm and gram-negative bacteria (Escherichia coli) of 8.67±0.58 mm, pH appropriate to pH of skin human (5.83±0.29), and viscosity following the hand sanitizer standard (2708 cps).

Abstract

ABSTRACTSeaweed is a type of algae that can live in marine waters and is the largest part of marine plants. This study aimed to observe the chemical composition of red seaweed (Eucheumaspinosum) originating from the Takalar Waters of South Sulawesi Province. The seaweedE. spinosumextract were evaluated for their chemical characteristics including the content of moisture, ash, protein, and the yield. The results showed that the chemical characteristics ofseaweed extracthad yield, moisture content, ash content and protein content of 5.23%, 21.27%, 1.55% and 5.74%, respectively. Keywords:chemical composition,Eucheumaspinosum, seaweed
