Development of Chemical Teaching Materials on Alcohol Compounds with the Context of Making Bioethanol from Cassava Peel (Manihot esculenta) to Build Environmental Literacy

Abstract

This research aims to produce chemical teaching materials regarding alcohol compounds in the context of making bioethanol from cassava peel using the 4STMD method to build environmental literacy. The research method uses Developmental Research (DR) which consists of design, development, and evaluation. The research participants were class XII students from a private high school in Bandung. The research instruments are the optimisation sheet, the four-stage 4STMD instrument, the feasibility instrument, and the understandability instrument. Stage development results design obtain a design for preparing teaching materials; results of stage development using the 4STMD method which consists of four stages, namely selection, structuring, characterisation and didactic reduction. The selection stage produced 17 competency achievement indicators and 16 concept labels. Concept development using 17 international textbooks and 2 high school chemistry books. Environmental literacy as a pedagogical context and making bioethanol from cassava peel as a substance context. In the structuring stage, a concept map, macrostructure and three levels of representation were obtained. In the concept map of the context of making bioethanol, cassava peel is part of making alcohol by biological means. In the characterization stage, 3 texts out of 36 texts were obtained which had to be reduced to didactics. Stage results evaluation. The results of the feasibility test for teaching materials were in the very appropriate category (98.28%) and the comprehensibility test was in the high category (87.05%) and had the potential to build environmental literacy.
