Church worship spaces have complex acoustic requirements because they are used for a range of liturgical activities, from speeches and scripture readings to congregational singing. These conditions demand an acoustic quality that can support clear speech and good musical quality. This activity aims to plan improvements to the acoustic quality of the St. Pius X Church in Karanganyar to meet acoustic comfort standards for worship activities. The methods used include identifying existing conditions, measuring noise levels using a Sound Level Meter, room modeling, and acoustic simulations to analyze parameters such as reverberation time (RT60), Speech Transmission Index (STI), D50, C80, and Lateral Fraction (LF). The analysis results show that the room's initial condition has poor acoustic quality, with an RT60 of around 3 seconds at mid-frequencies and low speech intelligibility. Improvements are made by modifying the room's surface shape, using a combination of absorbent and diffuser materials on the walls and ceiling, and arranging the speaker system. The simulation results show an improvement in the room's acoustic quality, characterized by a reduction in reverberation time, an increase in STI values of 50–65%, an increase in D50 values above 50%, and music quality that meets standards. This planning can improve the room's acoustics, making it better suited for speech and music during liturgical activities.
