Abstract

Bricks are bricks made from a mixture of hydraulic adhesives added with fine aggregate and water without any other additives and have a cross-sectional area of ​​the holes of more than 25% of the cross-section of the bricks and the contents of the holes of more than 25% of the contents of the bricks. The purpose of this final project is to design a brick making machine using compressor pressure, design the selection of body materials and frames made of U iron, the main driver is the compressor and the wind work system from the compressor is channeled to the modified car tire pressure tube (tiptop tube) and then assembling the components, namely the frame, car tire pressure tubes (tiptop tubes), brick molds and brick dough container. The final design of the design of the brick making tool uses compressor pressure, namely the brick printing tool is driven by air pressure on the compressor which is connected to a car tire pressure tube (tiptop tube) then will press the mold and produce bricks according to the number of castings.

Abstract

Noise is the occurrence of unwanted sounds including irregular sounds and sounds emitted by transportation and industry, so that in the long term it can disturb and endanger work concentration. The purpose of making this silencer test equipment is to determine the level of sound that can be heard properly. .Methodology used: In an impedance tube, two microphones are placed at one end of the impedance tube and a sound source is placed on the other side. Two microphones were placed between them which were used to measure differences in the acoustic impedance of the sound field produced. The results of the research carried out were the creation of a sound dampening device. This research was carried out in three stages, namely the stage of making sound dampening equipment. In this study, two types of specimens were used, namely from wood powder waste and cigarette butt waste with a thickness of 1 cm with a frequency used of 500 Hz, (wood dust = 0.0164. Cigarette butts = 0.0164) 1000 Hz (wood dust = 0 .0097, cigarette butts = 0.0114) and 1500 Hz.(wood dust = 0.0107, cigarette butts = 0.0139
