To partially reduce the use of cement, pozzolans from Lapindo mud are used as additives in mortar. Lapindo mud pozzolan was chosen in order to reduce the amount of mud that continues to increase and there is no solution. The research method used was an experimental method conducted at the Laboratory of Materials, Yogyakarta University of Technology for material testing, and for compressive and shear strength testing conducted at the Civil Engineering Laboratory of Yogyakarta State University. Tests carried out in this study are compressive strength tests for cube mortars totalling 3 test specimens, normal masonry mortar totalling 3 test specimens, and shear strength tests for masonry mortar with pozzolan 5%, 10%, and 15% which also made 3 test specimens for each percentage. The conclusion of this research is that the cube mortar has a compressive value of 8.35 MPa, normal masonry mortar is 0.27 MPa. For the results of the average shear strength of mortar with the addition of 5% Lapindo mud the shear strength dropped to 0.20 MPa, for the addition of 10% Lapindo mud the average shear strength rose to 0.32 MPa, then to the addition of Lapindo mud 15% the average shear strength increased to 0.29 Mpa. Thus, it can be concluded that the maximum average shear is at a percentage of 10%, which is 0.32 MPa, which is 0.05 MPa, or 18.5% higher than the normal masonry mortar without the addition of Lapindo mud pozzolan. Keywords: mortar, Lapindo mud, shear strength
