To reduce the negative impact of scientific and technological advances on the environment, great participation from the community is required. Starting from the goal then SMP Negeri 1 Tegowanu create Adiwiyata School program, to instill the importance of saving the environment to learners. Learning Model of Science and Technology Society (STS) is a learning approach based on constructivism theory, which emphasizes on the ability to build their own knowledge obtained by students by analyzing the events that occur in society due to technological progress. STM learning model is very appropriately applied to learning KD 7.3 on predicting the effect of human population density on the environment and KD 7.4. apply human role in environmental management to overcome pollution and environmental damage. In the learning process both cycle I and second cycle teachers use STS learning model, by exposing students to the events occurring in the environment due to the density of human population, for example with regard to water supply, availability of land, and limited employment.
