Based on observations made by researchers in class 1 of SDN 74 Kota Bengkulu, children were still found whose environmentally caring character had not yet developed, this was because the habits carried out by the teachers there had not been carried out optimally.

Based on the results of this research, the author can conclude that in the teacher's process of developing children's environmentally caring character through the habituation method there are still habituation steps that have not been carried out by the teacher, namely the teacher still has not reminded children who have forgotten to carry out positive habits in caring for the environment.
