This type of qualitative descriptive research was carried out in Jiken Village, Tulangan District, Sidoarjo Regency, East Java purposively using primary and secondary data. Data were taken by sampling with household interviews and analyzed to obtain answers to the research objectives. The results showed that the behavioral factors of the household preparing food include the number of family members, planning to prepare food, the amount of food preparation costs, the intensity of cooking a day, and whether or not they have ever learned to cook.
