Abstract
Masjid merupakan sarana ibadah utama bagi umat muslim yang membutuhkan kejelasan suara yang baik. Kejelasan suara membutuhkan kualitas akustik ruang dana tau sistem tata suara yang baik. Peningkatan kualitas kejelasan suara dapat dilakukan dengan perbaikan kualitas lingkungan akustik serta pemilihan dan penempatan speaker yang tepat. Perbaikan diawali dengan analisa kondisi akustik ruang masjid menggunakan parameter waktu dengung (RT60). Clarity dan Definition. Berdasarkan hasil pengukuran diperoleh nilai RT60 sebesar 2.24 detik, C50 sebesar -1.98 dB dan D50 sebesar 27%. Nilai waktu dengung belum mencapai nilai yang direkomendasikan yaitu 1.9 detik, sedangkan C50 menunjukkan kualitas ruang akustik sedang serta D50 yang menunjukkan kualitas akustik ruang yang buruk. Dengan kondisi ruang tersebut, dilakukan perbaikan kualitas akustikruang masjid dengan melakukan penambahan pemasangan karpet di lantai 1, sehingga diperoleh nilai waktudengung sebesar 1.84 detik. Hasil ini digunakan sebagai dasar simulasi pemasangan speaker dengan kondisi ruang terisi setengah penuh dan penuh. Simulasi dengan kondisi ruang setengah menghasilkan nilai terbaik %Alcons sebesar 6.46% dan STI sebesar 0.606 untuk pemasangan speaker F2000. Sedangkan hasil simulasi dengan kondisi penuh menghasilkan nilai rerata terbaik % Alcons sebesar 6.07% dan STI sebesar 0.617 dengan pemasangan speaker BS1030 di bagian depan lantai 2 dan F2000 di bagian belakang. Hasil yang lebih merata ketika menggunakan speaker F2000 baik di bagian depan maupun belakang ruang lantai 2 dengan rerata %Alcons 6.08% dan STI 0.616.

Masjid is the main place of worship for Muslims who need a good sound intelligibility. The sound intelligibility requires good room acoustic and or sound system quality. The improvement of speech intelligibility can be done with the improvement of acoustic quality as well as the selection and placement of the right speaker. Repair begun with an analysis of the masjid acoustics conditions using the parameters of the reverberation time (RT60), Clarity (C50) and Definition (D50). Based on the measurement results obtained RT60 value of 2.24 seconds, C50 of -1.98 dB and D50 at 27%. Reverberation time had not reached the recommended value of 1.9 seconds, while the C50 indicated the poor quality of the acoustic and D50 indicated a bad room acoustic quality. With the condition of the room, the improvements of the quality of room-acoustic of the mosque was done by adding carpet on the first floor, to obtain the reverberation time of 1.84 seconds. These result was used as the basis for the speaker placement simulation with the condition of the half-full and full room. The simulation of half-full room consition was resulting the best value % Alcons at 6.46% and STI for 0.606 with the speaker installation of F2000. While the results of the simulation with full conditions resulted the best average value %Alcons at 6.07% and STI at 6.17 with the installation of BS1030 speaker at the front of the 2nd floor and F2000 at the rear. More distributed value was resulted when using the F2000 speakers in the front and rear of the second floor room with the average %Alcons 6.08 and 0.616 for STI.
