This study aims to analyze the effect of adding cocopeat and glass powder on the quality of paving blocks based on compressive strength and water absorption at 28 days and to compare the results with SNI 03 0691-1996 standards. The mix variations include a control sample, 1% cocopeat as a partial replacement of fine aggregate, and a combination of 1% cocopeat with 1%, 3%, and 5% glass powder by cement weight. All samples were subjected to 28 days of water curing before testing. The results show that all variations achieved high compressive strength ranging from 32.94 to 36.30 MPa, exceeding the minimum requirement for Grade B according to SNI. However, water absorption values ranged between 7.40% and 8.38%, limiting the quality classification. The control and 1% cocopeat samples are categorized as Grade C, while mixtures containing glass powder fall into Grade D due to slightly higher absorption. Cocopeat increases porosity, while glass powder enhances compressive strength through filler effects and pozzolanic reactions, although it does not significantly reduce water absorption. Overall, these materials show potential as eco-friendly innovations with excellent mechanical performance, but optimization is needed to meet higher standards.
