This research investigates how heat treatment influences the physical, mechanical, and chemical characteristics of betung bamboo (Dendrocalamus asper). Two methods of heat treatment are applied: Oil Heat Treatment (OHT) and Air Heat Treatment (AHT), conducted at temperatures of 180°C, 200°C, 220°C, and 240°C, with durations of 1, 2, and 3 h. The study evaluates changes in color, weight, density, equilibrium moisture content (EMC), compressive strength, and crystallinity using X-ray Diffraction (XRD) analysis. Findings reveal that heat treatment causes significant modifications to the bamboo's physical, mechanical, and chemical attributes. Notably, OHT and AHT lead to substantial color changes, reflected in variations of L*, a*, and b* values depending on the temperature and treatment time. Weight and density decrease significantly after heat treatment, especially at 240°C for 3 hours. Additionally, equilibrium moisture content rises following treatment, while compressive strength diminishes. XRD analysis highlights alterations in the crystallinity and crystal size of the bamboo after treatment. In summary, heat treatment impacts the bamboo's characteristics, making it more suitable for industrial use as an improved raw material.
