Abstract

Riau Province has a vast palm plantation of 2,399,172 hectares (Statistics of Riau Province (BPS), 2014). Potency of dry waste of palm oil stem can reach 89.479.518,912 tons/year. Fiber can be used as an added material to make building materials such as brick. The purpose of this research is to find variation of mixture of brick-fiber maker with additional material of palm oil stem fiber to value of compressive strength and water absorption according to SNI quality standard. This research uses experimental method. The conclusion is jobmix brick-fiber which composition of cement 2,7168 kg; 8,1510 kg of concrete sand; and urug sand 5,4342 kg; water 0,1000 lt; fiber 1% (0,0272 kg), 3% fiber (0,815 kg), fiber 5% (0,1358 kg). Brick-fiber Dumai with average compressive strength value on 1%, 3% and 5% fiber additions were 110,80 kg/cm2; 79,30 kg/cm2 and 57,57 kg/cm2. Brick-fiber Pekanbaru has an average compressive strength value on the addition of fiber 1%, 3% and 5% respectively is 77,13 kg/cm2; 66,26 kg/cm2 and 67,89 kg/cm2. The absorption of brick-fiber water from Dumai is lower than 3,00%; 3,60% and 4,10% on the addition of fiber 1%, 3% and 5%. Absorption of brickfiber water of Pekanbaru for the addition of fiber 1%, 3% and 5% respectively 4,20%; 6,10%; and 5,70%. The finding of this research is that the value of compressive strength and water absorption of Dumai brick-fiber is better than Pekanbaru brick-fiber.
