The aim of this study is to determine the influence of coconut coir fiber on the compressive and flexural strength of paving blocks. The research was carried out using paving blocks with dimensions of 20cm×10cm×6cm, mixed with coir fiber by 0%, 0.1%, 0.2%, and 0.3% by weight. The results showed that no addition of coconut coir fiber resulted in compressive strength of 24.49Mpa, while the addition of 0.1% coconut coir fiber resulted in compressive strength of 25.39Mpa after 7 days. A mixture with no coconut coir fiber resulted in flexural strength of 31.5Mpa while the addition of 0.1% coconut coir fiber gave a flexural strength of 33Mpa in the age of 14 days. The conclusion of this study is that the addition of 0.1% coconut coir fiber in a paving block mixture can increase its compressive and flexural strength.
