This study aims to evaluate the characteristics of pumice as a substitute aggregate material for producing lighter, more economical, and environmentally friendly geo-paving. The research method includes literature review and laboratory testing focused on bulk density and mechanical performance of pumice-based paving blocks with three composition variations: 20%, 40%, and 60%. The results indicate that pumice from Pemepek Village has an average density of 0.72 g/cm³ and can reduce paving weight by 15–45% compared to conventional paving, although compressive strength decreases as pumice content increases. Overall, compositions containing 20–40% pumice are considered the most optimal in delivering well-performing paving blocks with higher ecological and economic value.
