Abstract The progress of developing building construction in our country affects the number of diverse building functions resulting in the number of buildings, the acceleration of the desired building, and the demand for higher-quality construction.
Mortar is a mixture consisting of Cement.
Fine Aggregate, and Water.
The adhesive in the mortar can be in the form of clay, lime, or cement.
Fine Aggregate (San.

Introduction The progress of constructing buildings that are developing in our country affects the number of various building functions resulting in the number of buildings, the desired acceleration of buildings, and demands for higher quality construction (Simanjorang & Nawawi, 2.
Mortar combines fine aggregate (San.
, binder (Portland Cement.
Clay.
Lim.
, and water.
The function of the mortar is the binding matrix of the constituent parts of a construction, both structural and non-structural (Umum & al S.
, 1.
The use of mortar for construction is structural, for example, masonry mortar for foundation structures, while for nonstructural purposes, for example, brick masonry mortar for infill walls (Sari.
Wallah, & Windah, 2.
The standard specifications for mortar refer to its compressive strength, namely where the mortar must be able to accept the load (Ali & Walujodjati, 2.
Considering that as a part of mortar construction, it plays an essential role in carrying loads, several factors influence the results of the compressive strength of the mortar, including the type of cement, the amount of How to cite:

Characteristic tests include sieve analysis, specific gravity and absorption, delicate aggregate gradation zone, fineness modulus, moisture content, silt content, organic content, and bulk density of fine aggregate.
Determination of Mixed Proportions Variations Determination of the proportion of the mixture is carried out to obtain data on the compressive strength of the specimens for each variation of the mixture.
Calculation of Mix Formulas The Mix Formula calculation is carried out to determine how much material is needed for the manufacture of the test object by calculating the total volume per proportion and using the data from the expected test results that have been done previously as additional data to calculate the Mix Formula.
Cement Water Factor Test (F.
The cement Water Factor Test (F.
) is carried out to determine the ratio of the proportion between cement and water so that the mixture is not excess water which can result in the compressive strength of the mixture not being maximum.
Test Objects I am making the test object using a square mold of 5 cm x 5 cm x 5 cm with the number of test objects per proportion of the mixture, namely as many as 9 test objects per .
Treatment of Test Objects (Curin.
Treatment of the specimen (Curin.

Treatment of the test object (Curin.
is carried out by immersing the test object in water until the compressive strength test is carried out.
This is done to keep the surface of the specimen constantly moist to ensure the cement hydration process .
