The current use of parametric design method helps architects or building designers in creating design geometries in a flexible manner, while simultaneously considering the room acoustic conditions. This method can be used as an alternative to design buildings with high complexity, one of which is a mosque. In Indonesia, there is no research on parametric design methods for achieving the optimum acoustic condition of mosque spaces, by considering variations in the pyramid ceilings geometry and the ceiling material type. In this case, it is necessary to consider the fulfillment of acoustic condition of the mosque, while still giving the perception of magnificent, with a reasonably good sound clarity. As a case study, in this final project, a square plan mosque building was modeled with Rhinoceros 3D software and its acoustic simulation were simulated with Grasshopper and Pachyderm plug-ins. This study considered three design input variables: the ceiling's length and width or area of truncated pyramid ceiling and the ceiling material's absorption coefficient. The variables were varied to obtain the maximum possible RT, D50, and STI values within the criteria range for each outcome variable. The correlation between the variable area of the peak of the pyramid ceiling and the coefficient of the primary ceiling material is of minimal value and mutual freedom. RT, D50, and STI are particularly sensitive to changes in the coefficient of the primary ceiling material compared to the area of the peak of the truncated pyramid. There is uncertainty in the distribution of acoustic parameter values with respect to changes in ceiling material, especially in the reverberation time parameter (RT), while for STI and D50, the distribution tends to be evenly distributed. Optimization was carried out by two methods: fair-weighted scoring and Pareto front. The solution set based on the second part of the optimization method resulted in a geometric design recommendation of the pyramid ceiling with the acoustic conditions of the space being met. There are five sets of optimum solutions recommended for ceilings with acoustical tile material in the scenarios with open door and one set of optimum solutions in the scenarios with closed door. As for other materials, such as concrete and wood, additional treatment is needed to meet the desired acoustic requirements.
