Abstract: Electrolytic oxidising water (EOW) is a disinfectant and sanitary material that is classified as easy to obtain, inexpensive, safe, and environmentally friendly. This study aims to determine the effect of electrodes and mineral salt concentration on changes in the properties of EOW such as potential hydrogen (pH), oxidation-reduction potential (ORP), and total dissolved solids (TDS) at various times, determine the toxicity of EOW to earthworms (Lumbricus sp.), and the disinfecting ability against bacteria (both gram-positive and gram-negative) was measured with disc diffusion method. The water used for EOW is rainwater in Yogyakarta. The study results show that EOW water is successfully produced by an electrolysis device and the EOW water used as a disinfectant is environmentally friendly. Furthermore, the use of EOW water as a disinfectant shows the ability to inhibit gram-positive and gram-negative bacteria, which is comparable to 70% ethanol.
