Abstract :
Coconut (Cocos nucifera L.) is tropical native plants and can be found throughout Indonesia, so that the plant can also cause negative such as piles of organic waste in the form of coconut husk ash and coconut shells. This study aimed to determine the utilization of such waste in the form of ash to reduce some of the use of cement in the manufacture of bricks with percentage of coconut husk ash and the number of different cycles of concrete additive. This study was conducted at Concrete Laboratory, Faculty of Engineering Universitas Sumatera Utara from April to June 2017. This study used a complete 2 factorial randomized design. The first factor is the composition of the coconut husk ash which consists of 3 levels, that is: 0%, 2.5%, 5% and the second factor is the combustion temperature of coconut husk ash which consists of 2 levels, that is: 700oC and 900oC. The result showed that the brick in the treatment of A1B2 (2,5% level at 900oC) is the best treatment for the compressive strength and absorption parameter with a compressive strength value of 14 MPa and the absorption of 0.92%, for the initial setting time and final setting time parameter contained in the treatment A2B2 with an initial setting time value of 84.8 minutes and a final setting time of 94 minutes.
