Abstract :
Deoil Bleaching Earth (DOBE) is included in the waste from processing the oleochemical industry or CPO so that it is included in the category of waste from processing animal/vegetable fat. In this study, the use of deoil bleaching earth aims to be a substitute for cement in mixing concrete. The method used in this test is to make a concrete mixture using SNI 7656:2012 with deoil bleaching earth as a partial cement substitution of 5%, 10%, 50%, and 20%. Concrete that was treated for 7 days, 14 days, 21 days, and 28 days was then tested to get the compressive strength and volume weight of the concrete. From the test results obtained the highest compressive strength value of 10.1 MPa with a variation of 10% deoil bleaching earth. This test shows that the greater the level of deoil bleaching earth in the concrete mixture, the lower the compressive strength value produced.
