Abstract

The use of bricks as a building material is more profitable than the use of bricks because bricks are easier and faster to install. Temperature resistance (heat) is one that affects the quality of bricks. One way to increase the heat resistance (temperature) of adobe bricks is to add a mixture of its manufacture, one of which is rice husk. Rice husk has the potential to increase heat resistance because it contains silica. Rice husk waste is mostly obtained from agriculture in the community, but the use of rice husk waste in bricks is still very less.. This study aims to analyze the temperature damping on adobe bricks with a mixture of rice husks. The method used is an experimental approach that begins with a survey of rice husk waste locations and sampling of rice husks at the Pegayut rice mill. The next stage was carried out experimentally in the laboratory. The bricks used were mixed with rice husk variations of 0.1, 0.2 and 0.3 of the composition used for cement. Research has been carried out to determine the attenuation of heat in bricks by placing a heating device on one side of the bricks and then measuring the temperature and on the other side after varying the time from 0 minutes to 15 minutes with with a time span of 5 minutes each. The results of the study showed that the greatest temperature attenuation was in bricks with a mixture of 30% rice husk at 5 minutes the damping time was 75.025 o C, 10 minutes at 79.282 o C and 15 minutes at 82.275 o C. Based on the factorial analysis, the 30% rice husk mixture is the brick with the best temperature damping..
