Abstract

Soil has high plasticity, expands when air content increases, shrink when conditions are dry. This property causes damage to constructions. So efforts are needed to improve it by increasing the stabilization of the soil itself. In this research, tests were carried out on clay soil originating from the Air Batu area, Banyuasin by adding a variety of mixed materials in the form of Calcium Carbonate (CaCO3) 2%, 4%, 6%, 8%, 10% of the dry weight of the soil and various mixed materials. In the form of optimum Calcium Carbonate (CaCO3) + Magnesium Carbonate (MgCl2) varying from 2%, 4%, 6%, 8%. Testing was carried out in two stages, namely, fascial properties testing which included air content testing, consistency limits, sieve analysis, hydrometer and specific gravity, then mechanical properties testing which included compaction testing, CBR (California Bearing Ratio), the research results showed that the addition of calcium carbonate (CaCO₃) has an effect on stabilizing clay soils. If the percentage of added calcium carbonate (CaCO₃) is greater, the value of the optimum water content will decrease further, while the addition of magnesium chloride (MgCl₂) to the soil is not suitable for stabilizing the soil.

Abstract

Flood disasters represent a serious threat to communities in various regions of Indonesia. One effort to anticipate floods is by conducting community outreach regarding established guidelines for early warning and emergency response. The early warning guidelines include early warning systems, risk identification, communication and education, preparedness training, and evaluation of lessons learned. This community service activity aims to provide knowledge to the community and to remind them to remain concerned about their surrounding environment in order to prevent flood disasters. The method used by the research team was to conduct field counseling by gathering several residents of RT 053, Bukit Lama Subdistrict. The counseling delivered material on early emergency response to flood disasters. This community service activity is expected to be implemented by residents when floods occur in residential areas, thereby significantly reducing potential losses.
