Child Friendly Integrated Public Space is one of the important policies/programs of the Special Capital Region of Jakarta Provincial Government to realize Jakarta as a Child Decent City. It is a place and/or open space that combines the activities of citizens by implementing the 10 Main Program for the Family Empowerment and Welfare with the Child Decent City Program. To find out the effectiveness of the Kenanga Child Friendly Integrated Public Space in Cideng Subdistrict, indicators for fulfillment of functions were used as contained in Article 4 of the Governor Regulation of the Special Capital Region of Jakarta Province Number 123 Year 2017 concerning Management and Requirements for Facilities and Infrastructure of Child Friendly Integrated Public Spaces. Data were collected through observations, document reviews, and in-depth interviews with informants consisting of the Secretary of the Family Empowerment and Welfare Activator Team, consultants, managers, and user communities. The collected data were analyzed using quantitative and qualitative descriptive analysis techniques. The results of the study concluded that the Kenanga Child Friendly Integrated Public Space has been effective in all indicators of fulfillment of functions, but still requires assistance from the government in terms of maintenance of infrastructure and facilities as well as the development of a management information system that is supported by a complete set of hardware, software, databases, as well as computer networks and data communications.
