The study aimed to assess people's knowledge, attitudes, and practices regarding hygiene, sanitation, and water use in Sukabumi District. It found that handwashing with soap and latrine use were not common. People's understanding of safe water was based only on appearance. Solid waste disposal and liquid waste management practices needed improvement. Effective health messages faced challenges like lack of media coverage and community priorities being economic over health-related. Factors like government program coordination and corporate social responsibility were also issues.
