Created in 2017 with an action research approach containing qualitative and quantitative studies (Mixed-method) to create applications based on input from mothers, cadres, community health centers, village heads and sub-district heads. These inputs can be used as improvements so that the iPosyandu application becomes more innovative and is integrated with the level of technological readiness of Posyandu cadres and mothers. Additionally, a mixed-method study was conducted in 2018 to evaluate this application. In 2019, this application will be researched for its cost-effectiveness so that it can strengthen the advocacy process to the government to help the government consider allocating the budget effectively in 2020 and beyond.T
