【 摘 要 】

Coconut Shell Powder were obtained from coconut shell that had been discarded and grinded until it become in a form of powder. This study were conducted to determine the chemical and physical properties of coconut shell powder to be used as a filler inside concrete. In order to do that, an experimental setup of X-Ray Fluorescence (XRF), Particle Size Distribution, Scanning Electron Microscopic (SEM), Density, and Specific Gravity were conducted. The coconut shell powder consist mostly carbon (C) and potassium oxide (K2O). The presents of silicon dioxide (SiO2) is crucial in order to be mix with concrete. The size of the coconut shell is ranging from 600μm and below. From all the testing, it is show that the coconut shell powder can be use in mixing with concrete as a filler.
