The use of thermal insulation materials in buildings is an important topic in an effort to increase the efficiency of electrical energy consumption. Natural fiber-based thermal insulation material is an alternative to the synthetic fibers that are widely used today. It is important to know the thermal stability of the materials as the basis for its feasibility as a thermal insulation material. Palm wood (OPW) and ramie fiber (RF) have potential as raw materials for thermal insulation from natural fibers. This study aims to assess the thermal stability of oil palm wood and ramie fibers as raw materials for thermal insulation materials based on natural fibers. Oil palm wood particles and rami fiber were treated before being tested. Oil palm wood is soaked in hot water 1000C for 30 minute and ramie fibers in 5% NaOH solution at the same time. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) tests were carried out to obtain the thermal characteristics of the two raw materials. Tests were carried out for both fibers, untreated and treated. TGA testing resulted in OPW and RF with treatment having better thermal stability than OPW and RF without treatment. OPW and FR with treatment have maximum thermal stability at temperatures of 3770C and 3990C. DSC analysis showed that OPW and FR with treatment produced peak temperatures at 4090C and 4080C respectively. The thermal stability of fibers will increase with treatment compared to untreated fibers.
