Islamic and conventional economic have different paradigm about solution that should be done. This study try to analyze the determinant of Indonesian inflation with two approaches model using Vector Auto Regression (VAR) and Vector Error Correction Model (VECM) methods.
The results of variance decomposition, show that contribution of independent variable in Islamic model is greater than conventional one with 14.8 percent and 7.4 percent, respectively. Other findings show that interest rate gives positive influence and dominant contribution to IHK than other variables both, in Islamic model (13%) and mixed model (39%). Therefore, interest system in the Indonesian economy should be reconsidered to achieve monetary stability.
