This study aims to determine the quality characteristics of soap using seaweed. The
research method was carried out experimentally by making soap from various types of
seaweed. The research data were analyzed using a T-test analysis of soap made from 15
grams of E. cottonii, 10 grams of E. spinosum, and 15 grams of E. spinosum. The
parameters analyzed were organoleptic (appearance, smell, texture), physical test (foam
stability, pH), chemical analysis (moisture content, free alkalis, fatty acids, free fatty
acids). Research shows that different use of seaweed affects the quality of the soap
produced. The use of seaweed E. spinosum as much as 10 grams is the best treatment
with the characteristics of soap, namely: it has a bright and clean appearance, fragrance,
a hard texture, not sticky, 75.2% foam stability, pH 8.60, 21.86% moisture content,
alkaline free 0.40%, 26.37% fatty acids and 0.68% free fatty acids.
