The lecture hall of the Department of Architecture, Faculty of Engineering, Universitas Brawijaya, is a room with a large volume of space. The room is close to M.T. Haryono Street, which has relatively dense traffic activity resulting in acoustic disturbance for lecturing activity inside the room. Thus, an improvement in the acoustic quality of the room is very much needed. Due to the high cost required to apply commercialized acoustic panels, this research experimented with coconut coir, corrugated cardboard boxes, and pro foam as acoustic panel alternatives. The simulation of three materials, each has a thickness of 4 inches and a total area of 87.88 m2, with four levels of origami pattern sparseness (Miura Ori, Ron Resch, Water Bomb, and Yoshimura) using Freeform Origami software shows a result of different volumes with convex, concave and flatforms. The convex and concave forms are chosen because both have good sound distribution qualities. The simulation is continued with SketchUp software on alternatives of four origami patterns to determine the effect on the reverberation time inside the room. The results show that the Yoshimura origami pattern achieves the best performance. It reduces the room reverberation time becomes 0.86 seconds.
