Abstract

This study analyzes the substantive implementation of Islamic economic principles in Islamic financial institutions based on the framework of Maqashid al-Shariah.A qualitative case study approach was employed, collecting data through in-depth interviews and document analysis. The findings indicate that the principle of wealth protection is realized through the avoidance of riba and gharar, although operational activities are more heavily dominated by sale-based contracts rather than profit-sharing arrangements. On the other hand, the integrated social function is carried out through the management of ZISWAF, yet its implementation often faces pressure to meet profitability targets. Tensions arise between adhering to formal procedures and achieving the intended benefits.

Abstract

The spread of SARS (Severe Acute Respiratory Syndrome) disease in a human population is one of the phenomena that can be mathematically modeled. The exposed period of SARS disease underlies the formation of the SVEIR epidemic model which is a modification of the SVIR epidemic model by adding subpopulation E (exposed). In the SVEIR model, there are two control variables in the form of vaccination and treatment which aimed to minimize exposed subpopulation, infected subpopulation, and control implementation cost. The Pontryagin’s minimum principle is used to obtain optimal control and system, thus minimizing objective functional as the objective to be achieved. Furthermore, the forward-backward sweep method is used for numerical simulation in order to determine the most appropriate control strategy in a finite time. The simulation results show that implementation of both vaccination and treatment is the most effective decision making to control the spread of SARS disease.Keywords: optimal control, Pontryagin’s minimum principle, SARS.
