ABSTRACT
The aim of this research is to identify the supporting factors for the sustainable development of productive cash waqf institutions in Indonesia. Currently, cash waqf in Indonesia is still mainly in the social sector, such as mosque development and social hospitals. Therefore, productive cash waqf must be developed further, especially for the supporting factors. The research method used is based on a qualitative case study with four productive cash waqf institutions. Some supporting factors are identified using main nodes in each aspect. The result shows that each aspect has an important issue, such as education (need early education on waqf), economics (supporting system to pay waqf), media culture (habitual activity to pay waqf), environment (not so familiar) and politics (supporting regulations and promotion). The additional helix is the belief of Muslims to participate in waqf which is the main factors.
