Application of the crystallographic tiling to increase competitiveness of the sand sediments

Abstract

Mount Merapi eruption in 2010 resulted in the environmental damage and disruption of socio-economic life of the society. Post-eruption cold lava floods carry the volcanic sedimentary materials in the form of sand and stone are very abundant. Unfortunately, the abundance of these natural resources is exploited at low prices. The problem is how to manage the sedimentation to have high economic value. The adaptation efforts to manage this sediment need to be done to immediately restore the social economic slump of society. The sediment management model that can improve economic value and competitiveness needs to be done by maintaining the sustainability of its natural resources. This article contains the results of research on the application of crystallographic tiling to improve the economic value and competitiveness of sand sediments. Three types of sediment-based products are successfully made of tiles, rosters, and paving.
