Data analysis using Chi-Square Test. 89.4% of online motorcycle taxi drivers are male, 76.1% have low levels of education, 58.7% have low-income levels, 32.2% have poor knowledge, 46.2% have poor attitudes, 48.3% had poor family support, 26.2% had poor peer support, 45.2% had poor information accessibility, and 47% had poor personal hygiene behavior. There is a relationship between knowledge (p-value <0.001) attitude (p-value < 0.001 ) and family support (p-value < 0.001 ) with personal hygiene behavior. Knowledge becomes the most influential determinant of personal hygiene behavior. Providing an educational menu in the driver application can help to increase knowledge.
