Research "Gel hand sanitizers without rinse made from seaweed, sopi and natural fragrances", was purpose to find out the physical characteristics and antiseptic power of the products produced. The research method used is an experimental method. The ingredients used are seaweed as a gel preparation, 65% sopi as an antiseptic material and cajuput oil and cinnamon as a natural fragrance. The treatment includes A = immersion of seaweed for 24 hours, consist of A1 = immersion in clean water and A2 = immersion in 3% NaOH solution. B = Natural fragrances, consist of B0 = No Fragrance , B1 = Cajuput Oil, B2 = Cinnamon extract . The results of the research show that physical characteristics include: the color of the product is influenced by the type of fragrance used, especially the fragrance that comes from natural ingredients that have a distinctive color. The product texture depends on the alkali treatment of seaweed that is used as a gel preparation. Seaweed without alkali treatment produces products in the form of thick liquids. Whereas seaweed with 3% NaOH solution produced semi-solid (gel) shaped products. The product gel is homogeneous with a pH value of 5.5 - 6.0. Antiseptic power includes inhibitory power for gram-positive bacteria (Clostridum perfringens and Staphylococcus aureus) generally weak, whereas gram-negative bacteria (Escherichia coli, Pseudomonas and Salmonella) are generally weak to moderate. The trial of product use in 10 volunteers showed no side effects from the products produced. The positive result of using the product is that the skin feels smooth. Key words: Handsanitizer, seaweed, sopi, cajuput oil, cinnamon extract.
