Abstract

Coconut fiber is lignocellulose contained materials can be obtained easily and used as one of raw materials alternatif of coconut fiber, coconut shell which consist of fiber located between inner hard shell, consist of about 35% from total weight of mature coconut. Beside easy to find, cheap, fiber coconut often be used because the making process is easy and much found at all area in Timor Leste. Also, bricks are material which easy to find and easy to make. Beside bricks, in the wall laying cannot be separated from the adhesive composer between bricks that is mortar. Mortar mix that is used in general consist of various comparison between cement: sand. The research want to know the influence of coconut fiber percentage 0%, 1%, 2.5% and 5% that is used in the mortar mix composition 1:15 with cement water factor of 0.7 toward cube compressive strength, flexural tensile strength, and brick laying. With horizontal, vertical and diagonal compressive direction of mortar. It was obtained that the wall laying. From the obtained results, the cube compressive strength of coconut fiber of 5.76 MPa, 3.30 MPa and 1.36 MPa while the without coconut fiber of 3.84 MPa. And also for the flexural tensile strength of 1.704 MPa, 1.659 MPa, 1.217 MPa, compared without coconut fiber of 1.212 MPa. The compressive strength test results of wall for horizontal direction of 0.9303 MPa, 0.9008 MPa and 0.044 MPa with strain of 0.0299, 0.0372 and 0.0344 compared without fiber of 0.8415 MPa with strain of 0.014, 0.0220 and 0.030 while without coconut fiber of 0.944 MPa with strain of 0.0224.
