<![CDATA[Waterborne diseases (WBDs) like cholera, typhoid, and diarrhea continue to be a serious public health concern, especially in rural Indonesia where there is a lack of health literacy and sanitation facilities. Due to poor sanitation and disjointed hygiene practices, Sumberejo Village in Gedangan, Malang, is extremely vulnerable. The program helps the community prevent waterborne diseases by promoting better hygiene and sanitation knowledge. 44 community members participated in a one-group pre-test and post-test design, with the majority being women from the Family Welfare Movement (PKK) and health cadres. The intervention was a 90-minute group session that included an instructional film and an infographic brochure that had been locally customized. Knowledge scores before and after the intervention were examined using the Wilcoxon signed-rank test. Participants' median knowledge scores significantly improved from a pre-test mean of 94.7 to a post-test mean of 96.9 (p = 0.031). Despite this cognitive improvement, no significant association was found between knowledge level and sanitation practices, highlighting a persistent knowledge–behavior gap. Integrated audiovisual and visual teaching resources work well to raise community awareness of waterborne disease. Future interventions, however, must address behavioral, environmental, and infrastructure reinforcements in addition to education if they are to produce long-lasting behavioral change.]]>
