Abstract: Postpartum is a time of risk, most maternal and infant deaths in the world occurs in the first month. Education is aimed at improving health literacy so that quality postpartum care will optimize the health and well-being of mothers and babies. The aim of the study was to develop and test the validity of postpartum health promotion media in Semarang, Indonesia. We conducted research for four months in 2020 (May-August) in Semarang City, Central Java Province, Indonesia. Two sub-districts were selected: North Semarang and Genuk; for having the postpartum mother risk the largest. We use research and development methods which are divided into three phases; needs analysis, development and validity testing of promotional media. Needs analysis was carried out by means of focus group discussions, semi-structured interviews involving eight material experts (midwives) and 10 users (third trimester pregnant women couples). Development based on a needs analysis was carried out by editing the media using Adobe Photoshop software. Testing the validity of the material involved eight material experts and 36 thematic data analysis and descriptive statistics. The results of the thematic analysis reveal four main themes, first: the limited movement of the midwife, mother and husband, second: postpartum knowledge as most of the respondents have less knowledge in postpartum care. Third, traditional beliefs and practices as midwives still find mothers who believe in myths and practice traditional postpartum , and fourth, m-health for postpartum care is not much known. This study produces a postpartum care promotion model using m-health that is acceptable and feasible to implement for improving postpartum care literacy.
