During the COVID-19 pandemic, activities to maintain personal hygiene, and environmental hygiene, including hand washing, reduce cross-contamination but are challenging to measure. Using the principles of self-awareness theory, we developed and tested a new instrument that produces a quantitative measure of personal hygiene. This study aims to determine the public's understanding of hygiene and sanitation. The training was given using online media with 119 participants. The results showed that the instrument was 95% valid. The level of practicality in understanding the content of the material reaches the level of 87%. Meanwhile, an average score of 83.95 was obtained for evaluating learning outcomes following training, indicating increased participants' knowledge of hygiene and sanitation attitudes. Participants' responses to the training activities were considered positive and positively impacted their psychology. Suggestions for follow-up from these findings is the need for training and socialization of clean and healthy living behavior in rural areas to improve the quality of public health in their environment, the majority of whom still lack knowledge of clean-living behavior.
