In the previous studies, we used 20 different percentage compositions for the plastic waste, rice husks, and sawdust added with cement adhesive. The best results were found in 30% plastic waste composition and 70% sawdust with Portland cement adhesive. In this composition, the result obtained is a sound absorption value of 0.468 s [1]. This study continues previous research, which includes analyzing the comfort of a prototype house with the best mix in previous studies. The method used is a sound absorption chorus test using research instruments such as microphones, real-time analyzers, and the INSUL application. This study aimed to determine whether the bricks made with the same mixing ratio have the same value when used in the house model and to determine the absorption value. This study found that the absorption value of the plastic waste bricks used for house prototyping walls has good absorption with a reverberation time of T 30 =0.468 seconds; the temperature inside the room is 30.8°C with a humidity of 54%, while at the same time the temperature outside is 37°C with a humidity of 57%.

Introduction The main theme of this research is waste utilization, specifically plastic waste, which is an inorganic waste that is difficult to decompose [2]. One component of buildings is the walls necessary as a space boundary in all parts building. Typical wall materials use mud brick or cement brick that requires a binder and finishing plaster specs on the outer surface [3]. Cement brick tends to only serve as a barrier but does not have a function as a sound or heat absorber. This research is a continuation of earlier research reported in two different papers. The first publication [4] focuses on research conducted into the production of composite bricks designed to meet the requirements of thermal insulation. A second paper [1] is produced as a result of this research, and it addresses testing the capability of the acoustic properties of the composite brick material that was developed. This study attempts to investigate the acoustic absorption in a one-to-one size building with walls built of a plastic waste brick composite after it has been occupied (inhabited). Noise is a collection of distracting and undesired sounds that diminish hearing. If the noise exceeds the continuous exposure threshold for humans, it can interfere with personal comfort and could cause hearing loss [6]. Consistent with Decree Number 48 of 1996 of the Minister of the Environment regarding the standard noise level, the noise threshold in residential areas is 55 dB at all times (there is no difference between day and night).
