Ionic liquids have superior properties compared with other solvents because they are environmentally friendly/green agents/renewable and are predicted to have the potential to improve the mechanical properties of bamboo. This study aims to examine the mechanical properties of bamboo with the application of ionic liquids and internal potential planning ESD learning at universities. This study used two kinds of ionic liquids: choline chloride-oxalic acid and choline chloride-ZnCl2. Testing the mechanical properties of bamboo using ASTM D-638 for tensile tests and ASTM D-790 for flexural and compression tests. The results found that the tensile, bending, and compression strengths for bamboo without ionic liquid treatment for each test are 0.0290 kN/mm², 0.1458 MPa, and 0.0587 kN/mm², respectively. For bamboo with a choline chloride-oxalic acid coating, the tensile, bending, and compression strengths are 0.1037 kN/mm², 0.2370 MPa, and 0.0609 kN/mm² respectively. For bamboo with a choline chloride-ZnCl2 coating, the tensile, bending, and compression strengths are 0.0737 kN/mm², 0.3191 MPa, and 0.0736 kN/mm² respectively. To understand the context-specific requirements for ESD integration in education, data was collected using open-ended questions. The results indicated the necessity to integrate ESD into chemistry education further, specifically emphasizing ionic liquids and their potential role in sustainable practices like bamboo processing. The use of ionic liquids in improving mechanical properties for ESD-loaded learning offers new insights into the potential of these compounds in understanding the mechanisms involved in the learning and knowledge process. © 2024 Published by ISRES.
