ABSTRAK
Coconut shell ash is waste generated from the process of burning coconut shells from the coconut shell industry. Coconut shell ash has the potential to be developed as a partial substitute for cement in the manufacture of mortar because coconut shell ash contains silica which can react with lime to produce CSH which is like cement so as to increase the compressive strength of the mortar. This study aims to determine the effect of adding coconut shell ash on the compressive strength of mortar. Before making the specimens, property tests were carried out on fine aggregate and coconut shell ash in the laboratory and the composition of the mortar mix was planned according to SNI 03-6882-2002. The test object is cube-shaped with a size of 5 cm x 5 cm x 5 cm with a total of 5 samples for each variation, and the mortar is tested after 28 days old. The variations used in this study used a ratio of cement and sand 1PC: 2PS, 1PC: 3PS, 1PS: 4PC, 1PC: 5PS with a mixture of 0%, 3%, 6%, 9% and 12% coconut shell ash. From the results of the mortar compressive strength test at 28 days, mortar with a ratio of cement and sand 1PC: 4PS and 1PC: 5PS has decreased from normal mortar, while the compressive strength value at a ratio of cement and sand 1PC: 2PS has increased compressive strength in coconut shell ash mixture as much as 3% with a compressive strength value of 17.36 MPa, and at a ratio of cement and sand 1PC: 3PS there was also an increase in compressive strength in the coconut shell ash mixture by as much as 3% with a compressive strength value of 12.8 MPa. From this value it can be concluded that the addition of coconut shell ash to certain mixture variations increases the compressive strength.
