This research was conducted to utilize durian peel waste as a useful material by maximizing its application to reduce environmental pollution and create commercial value. From this study, the idea emerged to process durian peel waste, which is rich in fibers, into a reinforcement material for composites. A composite is a material composed of two or more constituent materials. Composite materials consist of two elements: filler (fiber) and binder (matrix). The filler serves to improve the strength, stiffness, and elasticity of the material, while the binder functions to protect the reinforcement.

In the first year of research, several important outcomes were obtained, including: (1) the composition of composite concrete material reinforced with durian peel fibers; (2) mechanical properties in the form of compressive strength and splitting tensile strength of the composite concrete; (3) the design and production of road markings; (4) methods of measuring crack initiation in road markings using an airgun compressor; and (5) the response of road markings to impact loads using ANSYS software.

The results obtained in the second year were simulations of road markings reinforced with spiral steel bars using ANSYS software, showing stresses of 6.5 MPa on the X-axis, 8.4 MPa on the Y-axis, and 1.7 MPa on the Z-axis, with an equivalent stress of 9.40 MPa. In addition, high-velocity impact tests with variations in distances of 30, 40, and 50 cm indicated that cracking only occurred after seven trials. Therefore, the results of this research have the potential for mass production through collaboration with industrial partners.
