Abstract


Fields survey showed that multi-function auditorium design was done without involving acoustic expert. In this case, acoustic condition is not proper that cannot perform a good acoustic quality (Reverberation Time and Early Decay Time), as a result audiences are disturbed by over reverberation and echoes. The results of experimental simulation using the ECOTECT v5.20 program on multi-function auditorium at Petra Christian University showed that utilizing absorptive flexible material and easily adjusted such as baffle on the ceiling with 5% of covered area and drapery on the wall with 25% of covered area can adapt speech character. The dismantling of baffle from ceiling, the opening of drapery from the wall, and the adding of reflective material with 10% of covered area can adapt music character. Besides fulfilling design and acoustic criteria, both acoustic materials can be used practically for they can adapt functional changes and are also easily applied, short period and few labors consuming for implementation, mainly for existing multi-function auditorium.


Abstract in Bahasa Indonesia :

Pengamatan lapangan menunjukkan bahwa perancangan auditorium multi-fungsi seringkali dibuat tanpa melibatkan ahli akustik. Hal ini menyebabkan kondisi akustik tidak memadai sehingga tidak mampu menampilkan kualitas akustik (Reverberation Time dan Early Decay Time) yang baik, akibatnya penikmat merasa terganggu oleh dengung yang berlebihan dan echo. Hasil simulasi eksperimental menggunakan program ECOTECT v5.20, untuk meningkatkan kualitas akustik pada auditorium multi-fungsi Universitas Kristen Petra, menunjukkan bahwa penggunaan bahan absorbtif yang fleksibel dan mudah disesuaikan seperti baffle di plafon seluas 5% dan drapery di dinding seluas 25% mampu mengadaptasi karakter speech. Penurunan baffle dari plafon dan penyingkapan drapery di dinding serta penambahan bahan reflektif seluas 10% mampu mengadaptasi karakter music. Selain memenuhi kriteria desain dan akustik, kedua bahan akustik di atas dapat dipergunakan dengan praktis karena mampu nmengadaptasi perubahan fungsi, memudahkan dalam pengerjaan, menghemat waktu dan tenaga kerja dalam pemasangan, terutama pada auditorium multi-fungsi yang sudah ada.

Kata kunci: auditorium multi-fungsi, optimasi desain interior, peningkatan kualitas akustik ruang.
