Seaweed Gracilaria verrucosa is one of the potential marine natural resource commodities in Karawang Regency, Indonesia. The G. verrucosa-enriched bar soap is one of the added value products that can be developed from seaweed since it has a potential antiseptic function for human skin. Also, the seaweed-enriched bar soap sale can give more incomes for the seaweed farmers and coastal community in Karawang Regency. This study aims to produce bar soap with the addition of different seaweed G. verrucosa formulation and to examine the sensory, physicochemical, and bioactivity characteristics of G. verrucosa-enriched bar soap. This study applied five variants: the bar soap with extract of water + 250 ppm of seaweed (W250), extract of water + 500 ppm of seaweed (W500), extract of water + 750 ppm of seaweed (W750), extract of ethanol + 750 ppm of seaweed (E750), and seaweed pulp (SWP). The bar soap of variant W500 has the highest attributes according to the sensory and physicochemical analysis, while the variant SWP has the highest bioactivity parameter. From the results, the bar soap of variant W500 and SWP can be the candidates for further product development.
