| dc.description.abstract | The global issue of solid waste continues to escalate, with UN data indicating that approximately 11.2 billion tons of solid waste are generated annually, most of which originates from human activities. One significant source of this waste is the sugarcane processing industry. In Indonesia, sugarcane production reached 2.49 million tons in 2015, generating approximately 90% bagasse, 5% molasses, and 5% water. This study aims to explore the use of sugarcane bagasse fiber as an additive material in the production of interlocking bricks to improve the mechanical, acoustic, and thermal performance of walls. In 2017, many earthquake-related casualties were caused by collapsing walls rather than the earthquake itself, particularly walls made from conventional heavy bricks. Innovations continue to develop, including the concept of stronger and lighter bricks. This study utilized variations of sugarcane bagasse fiber addition at 0%, 10%, 20%, 30%, 40%, and 50% by weight of cement. The tests conducted included compressive strength (at 28 days) and density for mechanical properties, as well as acoustic and thermal performance tests on interlocking bricks using the optimum composition of sugarcane bagasse fiber. The results showed that the 10% bagasse fiber composition provided the optimum results in terms of compressive strength and density. Moreover, sugarcane bagasse fiber was proven effective in improving thermal performance (by reducing heat) and acoustic performance (by sound absorption). In conclusion, the addition of sugarcane bagasse fiber as a mixing material has great potential not only for reducing industrial waste but also for producing environmentally friendly wall materials capable of reducing heat and dampening excessive noise | en_US |
