Abstract
Bamboo is a tall grass in the form of jointed wood which belongs to the Poace subfamily group with its main constituent components in the form of cellulose, hemicellulose, and lignin connected by covalent bonds. Bamboo has several advantages, namely fast growth rate, high elasticity, easy to shape and cheap. However, bamboo has flammable properties, and to overcome this, it is necessary to engineer fire-resistant bamboo, one of which is using ionic liquids. The purpose of this research is to obtain a concept map and TLS (teaching learning sequence) from scientists^ conceptions of engineering refractory bamboo using ionic liquids. This study uses a qualitative content analysis method whose stages include literature collection (textbooks, review articles and research articles), descriptive analysis, category selection, and material evaluation. This research will produce 5 sequences of learning materials, namely bamboo, the main components of bamboo, the weakness of bamboo, ionic liquids, and chemical bonds. The topic of refractory bamboo engineering integrates chemical bonding materials (covalent bonds and ionic bonds) and polymers. This topic also applies the principles of green chemistry through the use of ionic liquids as a solution to prevent the combustibility of bamboo. The results of this research in the form of concept maps and TLS will be used in the development of teaching materials and didactic designs.
