Penggunaan Abu Serabut Kelapa Sebagai Substitusi Semen dan Tempurung Kelapa Sebagai Substitusi Agregat Kasar

Abstract

Coconut shell and coconut fiber waste are types of waste generated from the coconut industry, with a significant quantity. The main issue related to this waste is its inefficient handling, which can lead to environmental pollution and health problems. By utilizing coconut shells as a substitute for coarse aggregate in concrete mixtures, we can reduce the amount of waste disposed of and decrease dependence on conventional materials. Additionally, the ash from coconut fibers, produced from burning the fibers, can be used as a substitute for cement. The use of coconut fiber ash not only reduces the use of Portland cement, which has a high environmental impact, but also can improve the mechanical properties and durability of concrete. This research aims to explore the use of coconut shell waste as a substitute for coarse aggregate and coconut fiber ash as a substitute for cement in concrete mixtures. With the increasing demand for construction materials and the environmental impact of conventional materials, the utilization of agricultural waste such as coconut shells and fibers presents an attractive alternative. The experimental methods used include testing the physical and mechanical characteristics of the concrete mixture, as well as analyzing the variation in substitution proportions. Previous studies have shown the potential of coconut waste in enhancing concrete properties, both in terms of compressive strength and environmental resistance. The results of this research are expected to contribute to the development of sustainable construction technology and waste reduction, as well as promote the use of environmentally friendly materials in the building industry.
