Abstract

the potential to be a composite reinforcement and increase sound absorption through the Chemical Pulping process. This study aims to investigate the alleged influence of the use of matrix type on the strength of sound absorption in chicken feather fiber composites. The research method used is experimental research with the manufacture of composite specimens that vary the volume fraction of composite fibers with various types of matrices. Sound absorption testing using impedance tubes. Data analysis techniques in this study use descriptive data analysis. The results of this test show the effect of using matrix type on increasing the absorption coefficient of SBA composites. The maximum absorption coefficient is found in the SBA-K composite (Chicken Feathers – Kanji).

Abstract

Kenyamanan audial merupakan salah satu faktor dalam perencanaan bangunan, khususnya bangunan ibadah seperti gereja. Dalam mencapai kenyamanan audial ruang, arsitek hanya mengacu pada standar yang telah direkomendasikan oleh para ahli tanpa mengetahui pendapat dari pengguna ruang tersebut. Tujuan penelitian ini adalah untuk mengevaluasi dan menyajikan saran desain agar kenyamanan audial pada ruang gereja bisa tercapai. Metode penelitian kuantitatif dengan menganalisis data secara statistik-deskriptif. Alat Sound Level Meter digunakan untuk mengetahui distribusi tingkat tekanan bunyi dalam ruang gereja dan bising latar belakang yang dapat mengganggu suasana khidmat gereja. Waktu dengung dihitung dengan rumus Sabine, redesain dilakukan dengan simulasi menggunakan program Autodesk Ecotect Analysis 2011, serta kuesioner diolah dengan menggunakan program IBM SPSS Statistics 25. Hasil penelitian menyimpulkan bahwa distribusi tingkat tekanan bunyi telah merata, sedangkan bising latar belakang dan waktu dengung dalam ruang gereja masih melebihi standar. Namun secara keseluruhan, pengguna telah merasa nyaman dengan kondisi audial ruang gereja tersebut. Selanjutnya, jarak dari sumber bunyi dapat mempengaruhi tingkat tekanan bunyi, kebocoran suara dapat mempengaruhi bising latar belakang, serta penggunaan material dan perabot dapat mempengaruhi nilai waktu dengung ruang. Penelitian ini diharapkan dapat menjadi acuan dalam mendesain gereja selanjutnya atau bangunan sejenisnya.

Abstract

Mosque as a place of worship for Muslims demands to provide the maximum comfort for its users to make worship more solemn. In fact, many mosques do not pay attention to the comfort of the room, including the acoustic design. This research was conducted using I-SIMPA software, a software used to perform acoustic simulations involving geometric and acoustic parameters on architectural elements in the room with the aim of analyzing the reverberation level in the Makassar Grand Mosque space. The result obtained from analysis on the first floor shows the lowest reverberation time (RT) for 1.13 seconds at points 5, 6, and 8 at 8000 Hz. Moreover, the highest RT is 4.1 seconds at point 5 at 250 Hz and points 2 and 6 at 500 Hz which is exceeds the standard of recommended RT. On the second floor, The lowest RT is 1.38 seconds at point 1 at 8000 Hz and the highest is 4.86 seconds at point 3 at 1000 Hz. The reverberation time in second floor is longer compared to the first floor due to the volume and shape of the room. Keywords: acoustics performance, accoustic simulation, I-SImpa, Mosque room, reverberation time
