<![CDATA[Background: Acute Respiratory Infection (ARI) is the disease with the highest number of cases in Indonesia, with one of the often-overlooked environmental risk factors being mold growth caused by indoor humidity and poor waste management. Objective: This community service activity aimed to improve public knowledge and awareness regarding the relationship between environmental mold, waste management, and the risk of ARI, as well as to encourage the implementation of clean and healthy living behavior (PHBS). Methods: The activity was conducted on Saturday, 23 April 2026, from 07:45 to 10:00 WIB at Tembok Dukuh X Balai RT 12 RW 01, Tembok Dukuh Sub-district, Bubutan District, Surabaya, targeting 25 residents. The implementation method consisted of a pretest, education and outreach, interactive discussion, a waste management demonstration, and a posttest as the evaluation instrument using an 8-item multiple-choice questionnaire. Results: The results showed an increase in the participants’ average knowledge score from 6.88 (median 7; range 4–8) at pretest to 7.69 (median 8; range 7–8) at posttest, accompanied by a narrowing score range indicating more even understanding among participants. Conclusion: This activity proved effective in improving community knowledge regarding ARI risk mitigation due to environmental mold and waste management, and is expected to be applied sustainably in daily life.]]>
