Abstract

Nickel laterite is a rare mineral, but it is widely found in Indonesia, and its deposits are on the surface. The processing of laterite nickel must consider sustainability from economic, social, and environmental aspects by integrating basic molecular principles. This research was conducted to obtain a scientist^s conception of nickel extraction from laterite using ionic liquids and presented as a consequence map for teaching and learning. The method used is a qualitative method of descriptive content analysis. The examined categories and options will be presented according to two expert opinions in content analysis. Arrangements have been made in conformity with expert opinion. Questionable data are discussed holistically against content analysis. The results showed that laterite nickel content for teaching and learning could be analyzed through a descriptive approach. The scientists^ conceptions include definition, electronic configurations, properties, abundance, production processes, recycling, use of ionic liquids in nickel deposition, and applications. The concept map illustrates the potential desirable and undesirable consequences of nickel metal. Through qualitative content analysis, it is proven that nickel deposition can be carried out at a rate of ionic liquids deposition that can integrate sustainability principles from economic, social, and environmental aspects. Material development can be presented through experiments on the topic of transition metals. Further development of this research is expected to be used to obtain other alternative solvents that are environmentally friendly. Concept- and sequence- map (consequence-map) can be used to develop teaching materials.
