Abstract

The World Cement Association reported in 2024 that global demand for cement continues to rise, despite the material’s non-renewable nature and significant environmental impact, contributing to 8% of total CO₂ emissions. This research explores the use of bagasse fiber as a partial substitute for cement in concrete production to reduce cement consumption, produce eco-friendly concrete, and repurpose sugar industry waste. The study aims to determine the optimal composition of bagasse fiber in precast concrete by evaluating compressive strength. Using a quantitative, experimental method, 30 concrete samples with varying bagasse fiber content—0%, 5%, 10%, 25%, and 30%—were tested for compressive strength, with six samples per variation. Bagasse fiber content was the independent variable, while compressive strength was the dependent variable, measured in accordance with SNI-7394-2008 standards. Results indicated that increasing bagasse fiber content decreased concrete compressive strength. Samples with 30% bagasse fiber achieved 0.62 MPa at 14 days and 0.91 MPa at 28 days, meeting the criteria for lightweight, low-strength concrete (0.35–7.00 MPa) suitable for heat-retaining walls. This study contributes to sustainable construction by reducing bagasse waste and promoting accessible, eco-friendly concrete production for small and medium-sized enterprises.
