Abstract: Mortar is a building material consisting of a mixture of cement: sand and water with different percentages. Shear force/strength is an important element of the mechanical properties of the mortar. The purpose of this research is to create a multifunctional shear strength test tool that helps to obtain the shear strength of various building materials, where the building materials are mortar and concrete, as well as wood used for molding/begesting. If the finished object, for example: paving, brick and hebel brick and others. In the trial process of the multifunctional shear strength test equipment/running multifunctional shear strength test equipment, the test objects are in the form of rectangular paving and hexagonal paving. Mortar Mixture 1 PC: 5 PS, in the form of rectangular paving material which is formed into a Test Sample with a total of 12 PC samples. And in implementation it failed so that the number of samples = 9 PCs. , from the results of the Test Execution, Shear Strength with the equation Y = - 0.1792 X2 + 5.5733 X + 2.0228 and its correlation R2 = 0.9779. And 1 PC Mortar mixture: 4PS + Split Mixture of shell shards as exposure in the form of hexagon paving, with a total sample = 7 PCs. obtained Shear Strength with the equation: Y= - Ln (X) +55.782 and the correlation R2= 0.9639. So it should be in teaching and learning activities need to be supported with adequate laboratory equipment facilities. Considering that Polytechnic graduates are prepared to become ready-to-use staff, they need to be supported by various skills. Specifically, majors in civil engineering include being able to operate related workshop equipment. laboratory testing equipment. One of the several tests in the building materials laboratory is the Shear Strength test so that on this occasion a Multi- function Shear Strength Test tool will be created so that students can not only imagine it from the instructor, but need to understand and be skilled in operating the Shear Strength testing equipment as a provision for work later Keywords: Creating Multi-function Shear Strength Test Equipment, Research, learning.
