Spent Bleaching Earth (SBE) is one of the problems that triggers soil damage due to its fairly common use but minimal utilization of this waste. SBE is waste resulting from Crude Palm Oil (CPO) filtering. CPO during initial processing has a color that tends to be dark, so it requires bleaching powder (Fresh Spent Bleaching Earth) to filter the oil. The remainder of this filtering is known as SBE. If this waste is allowed to accumulate for too long, it has the potential to cause damage to the soil and the surrounding environment, even land fires due to the oil content in it. Therefore, in the form of utilizing and reducing environmentally damaging waste, innovation is needed, such as using this waste into the concrete mix. The process of making this concrete will be the same as concrete in general but using a different mix so that this waste can be optimally utilized. Based on the test results obtained, SBE has the potential to be one of the recommendations for concrete mixtures that are applied to seawater because the compressive strength increases as the concrete ages by 36.2% at 28 days. Whereas in fresh water the compressive strength value tends to decrease by 15.9%. So based on testing, SBE is more suitable for use in seawater environments than freshwater.

Bleaching Earth is a material used to refine palm oil to make it brighter in color as we currently consume.However, due to this, the accumulation of Bleaching Earth is increasingly uncontrolled and continues to accumulate.Previously, this research had been carried out but had not found a major impact on concrete durability. Especially incoastal areas which are often exposed to high chloride ions and have the potential to damage concrete. This research aimsto create a material that can modify the properties of concrete to have better durability by modifying Spent BleachingEarth using seashells. This research uses a cylinder measuring 150 x 300 mm with a various admixture. In this research, 3(three) stabilization fraction models were tried, namely Fraction A with 60% SBE and 40% Seashells, fraction B with50% SBE and 50% Seashells, and fraction C with 40% SBE and 60% Seashells. The research showed that fraction Bshowed compressive strength reaching 22,85 MPa and Fraction C showed compressive strength up to 29,44 MPa at 28days. Meanwhile, Fraction A experienced a decrease in compressive strength, reaching only 20,64 MPa compared tonormal concrete of 21,90 MPa at 28 days. This could be caused by many things, so further research is needed regardingthe stabilization of these two materials. Based on the research, it can be concluded that Fraction C can be arecommendation because it has higher strength than other fractions and needs to be tested in aggressive environments,especially in coastal areas
