Utilization of Sidoarjo Hot Mud for the Production of Low-Strength Concrete

The idea of this research departs from two problems; Sidoarjo hot mud eruption disaster in Renokenongo Village, Porong District, Sidoarjo Regency which until now requires handling solutions, as well as the increasing need for concrete for the construction of various infrastructures which is increasing – which is accompanied by limited resources. The resources needed for the manufacture of concrete include sand, cement, and split stone. Sand is a material that comes from nature and cannot be renewed, so its abundance is decreasing. This study seeks to actualize the idea of using Sidoarjo (Lusi) hot mud as a substitute for sand for the manufacture of low strength concrete. One of these types of concrete is needed for the construction of domestic sewers. This community service research is a development of previous research conducted by researchers related to the potential of Sidoarjo hot mud for the production of irrigation lining concrete, where a feasibility test of concrete produced has met the criteria for compressive strength of concrete according to national standards.
