The implementation of PHBS in households is the responsibility of each household member, which is also the responsibility of the government/city and the ranks of the relevant sectors to facilitate PHBS activities in households to be carried out effectively. In the home, the mother has a massive role in giving an example, role model, education in a family. Mothers also dominate in regulating food menus and keeping the house clean, including providing health education in the family, such as planting PHBS. The study was designed in the form of qualitative research with an in-depth interview approach. The informants in this research were 12 people consisting of 5 key informants and seven regular informants. The interview guide was built based on ten indicators of PHBS at the household level. All indicators of PHBS at the household level have been successfully elaborated. Interestingly, in this study, some informants give breast milk for less than six months. Then what is interesting is the habit of consuming fruits and vegetables from local fruits and vegetables. Smoking behavior has become part of the culture of Mandar society.
