Abstract
Tugas akhir ini bertujuan mengevaluasi kinerja akustik ruang masjid berplafon tajug agar memenuhi standar kriteria akustik ruang dan studi pengaruh perubahan geometri plafon. Penelitian dilakukan pada Masjid As-Sakinah dan Masjid Darul Hikmah. Untuk mencapai tujuan tersebut dilakukan pengukuran akustik menggunakan SLM (Sound Level Meter) sebagai dasar untuk melakukan evaluasi. Hasil pengukuran menunjukkan Background Noise pada Masjid As Sakinah bernilai 41.896 dB dan Masjid Darul Hikmah 41.12 dB; Noise Criteria sebesar 36.12 dB pada Masjid As-Sakinah dan 35.15 dB pada Masjid Darul Hikamh; dan waktu dengung bernilai 1.83 detik pada Masjid As-Sakinah dan 2.84 detik pada Masjid Darul Hikmah. Setelah dilakukan perbaikan, waktu dengung menjadi 1,16 detik pada Masjid As-Sakinah dan 1,27 detik pada Masjid Darul Hikmah. Nilai tersebut sudah memenuhi kriteria akustik yang baik menurut Ribeiro. Dan hasil perubahan geometri menunjukkan, penambahan luasan plafon 30% bisa menurunkan waktu dengung Masjid As-Sakinah menjadi 1,64 detik dan C50 menjadi -3,21, begitu juga pada Masjid Darul Hikmah waktu dengung menjadi 1,25 detik dan C50 menjadi -1,73. Hasil tersebut lebih baik dari kondisi eksisting.
=================================================================
This final project was conducted with the aim to evaluate room acoustic performance in mosque with tajug ceiling form to be in accordance with standards and study the effect of changing the geometry of the ceiling. The research was conducted at As-Sakinah Mosque and Darul Hikmah Mosque.. To achieve these objectives, direct acoustic measurements are made using SLM (Sound Level Meter) which is the basis for evaluation. The measurement results show that background noise at As-Sakinah Mosques 41,896 dB and 41.12 dB at Darul Hikmah Mosque; Noise Criteria is 36.12 dB at As-Sakinah Mosque and 35.15 dB at Darul Hikmah Mosque; And the reverberation time of both mosques is worth, 1.83 seconds at As-Sakinah Mosque and 2.84 seconds Darul Hikmah Mosque. After repairs, the reverberation time becomes 1.16 seconds at As-Sakinah Moosque and 1.27 seconds at Darul Hikmah Mosque. That value already meets good acoustic criteria according to Ribeiro. And the result of the geometry change shows the addition of 30% ceiling can reduce the reverberation time to 1.64 seconds and 1.25 seconds, C50 becomes -3.21 and -1.73. The result is better than the existing condition.
