Green Chemistry principle: Ionic Liquids as a material teaching for vocational students

The development of human civilization is characterized by the type of material used by society. The rapid development of material engineering and technology produces a variety of advanced materials such as smart materials, natural materials, chemical materials, nanomaterials, advanced materials, and environmentally friendly materials. Ionic Liquids (ILs) have criteria that are expected to be environmentally friendly because of their Green Chemistry (GC). The vocational syllabus needs to be reconstructed to be able to adapt this material technological progress. The purpose of this study was to determine the opinions of lecturers on the adoption of Ionic Liquid material teaching materials in vocational education in an effort to deal with the use of environmentally friendly materials that are indispensable in the industrial field. The subject of the study was taken through a purposive sampling method. There were 5 lecturers in one of the private polytechnics. Data collection through questionnaires is intended to determine the views of lecturers on ionic fluid material teaching materials and analyze the material requirements to be adopted into the vocational curriculum. The investigation results show that the interest and willingness of the lecturer to study and disseminate reached a score of 80%, this means that the lecturer needed the Ionic Liquid material. However, the teacher's understanding score still needs to be improved, so that it is necessary to design an Ionic Liquid teaching material that is interesting and easy to understand by both lecturers and students. The implications of this study can be used as recommendations in learning to be able to enrich the syllabus by adding Ionic Liquid material teaching material as an indispensable teaching material along with technological advances in industry 4.0.
