This study aims to determine the development map of mathematic model in islamic economics and finance research that is indexed by Scopus and other reputable journal with the keyword "Mathematic model in islamic economics and finance". The data analyzed were 100 selected publications. The development map of mathematic model in islamic economics and finance research analyzed using the VOSviewer application program to find out the bibliometric map. The results showed that the number of publications on the development of mathematic model in islamic economics and finance research indexed Scopus from 1983-2019 experienced a significant increase and the most were published in Journal of King Abdulaziz University: Islamic Economics. Network visualization showed that the map of the development of mathematic model in islamic economics and finance research was divided into 3 clusters. The majority of research is related to modeling of Profit Loss Sharing (PLS) schemes. However, despite the development of using mathematical model in those researches, the approach tends to be adaptive (inductive) from conventional models that already exist. A challenge to review the mainstream model need to be further critically reviewed. Hence, it is necessary for researcher to formulate a mathematical model with a deductive approach that is reduced from Islamic norms or ethics derived from the Alquran and Sunnah.

This study attempts to identify the causes and dominant factors that are obstacles in the development of cash waqf in Indonesia, using the IFE EFE Matrix and SWOT methods, and the solutions offered.

This study attempts to identify the causes and dominant factors that hinder the development of cash waqf in Indonesia, using the IFE-EFE Matrix and SWOT methods, while offering solutions to solve it. Based on the results of IFE analysis, the highest-rank of strengths is the ability of cash waqf in expanding the base of waqf fund sources followed by the ease and zero cost of funds. In comparison, the top weaknesses are the lack of socialisation to the community and the lack of professional nazhir human resources. The results of EFE analysis imply the highest-rank opportunity is the potential of unlimited cash waqf followed by the emergence of many sharia financial institutions and Islamic economics study programs in universities. Meanwhile, the top threat is a weak political will of authorities, followed by the majority of traditional nazhir. It is expected that there will be a joint commitment from various parties, both from policymakers and academics and practitioners to support and encourage efforts to develop the Islamic (social) finance industry, especially in developing cash waqf in Indonesia.
