East Kalimantan is an area which rich in natural resources, as a Mahakam sand and local stones. They also have abaca fibre waste to increase the flexural strength of concrete. This material is still underutilized by the people of East Kalimantan. But, they prefer to use materials imported from Palu, Sulawesi, so the unit price of concrete is very expensive. The purpose of this study was to investigate the effect of local Kalimantan material and abaca fibre on the strength of concrete. This research begins with a literature review, then material procurement, and material testing. After that, make a concrete mix design. Make of specimens with a variation of abaca fibre 0%, 0.4%, 0.5% and 0.6%. Then the compression test at the age of 7, 14, 21, and 28 days. The flexural strength testing at the ages of 28 days. From the test results can make analysis and conclusions. From the research results, it indicated that the maximum compressive strength in the addition of abaca fibre 0.0% with the compressive strength 27.31 MPa, and the maximum of flexural strength in the additional of abaca fibre 0.6 % wth flexural strength 3.56 MPa.
