<![CDATA[Soap is a cleansing product produced from the saponification reaction between oils or fats and a base, forming fatty acid salts that can lift dirt. This research aims to utilize dragon fruit skin extract and honey as sources of antioxidants in solid bath soap. The process was carried out on a laboratory scale using Virgin Coconut Oil (VCO) as the source of fatty acids that reacts with NaOH solution. The formulation was varied at the ratios of dragon fruit skin extract:honey 0:8; 2:6; 4:4; 6:2; 8:0 mL and a volume of 30% NaOH of 4, 6, 8, 10, and 12 mL. The extract and honey serve as antioxidants, while VCO increases skin softness and moisture. The results show that the soap meets SNI standards for solid soap. The best formulation is at a ratio of 6:2 for dragon fruit skin extract and 10 mL of NaOH, with a pH of 9.12, moisture content of 11.6%, an organoleptic score of 4.16, a 67% reduction in bacteria, and very strong antioxidant activity with an IC₅₀ of 3.4879 ppm (10 ppm). This combination of natural ingredients has the potential to produce environmentally friendly solid soap that is beneficial for skin health.
