Utilization of Pineapple Leaf Fiber as An Added Material for Environmentally Friendly Earthquake-Resistant Concrete Repair at LPG Lombok-Indonesia Terminal
Concrete is a building material that is often used because it is strong against presses but weak to bending forces. A solution is needed to fix the weakness. To overcome this, this study was conducted to increase the strength of the compressive force and bending force on environmentally friendly earthquake-resistant concrete, as well as reduce the pollution of concrete materials in the Lombok LPG Terminal. This research uses a descriptive qualitative approach starting from literature studies, repair preparation, implementation of improvements, strong press, and strong flexure tests, analysis and discussion, and conclusions. The results showed that the compressive and flexible strength of concrete that was given additional pineapple leaf fiber material with a composition of 15% had a strength greater than normal concrete. In conclusion, the utilization of pineapple leaf fiber in the manufacture of environmentally friendly earthquake-resistant concrete is able to increase the compressive strength and strong bending of concrete.
