The natural environment is not just a place for humans to live, but a place where there is a synergistic contact of life between humans and nature, both of which influence each other. which is expected to have a positive impact and can produce actualized productivity in environmentally literate human behavior. This study itself aims to determine environmental care programs through hydroponic plants that are integrated with social studies learning using a project-based learning model to develop ecological intelligence of STKIP Bina Mutiara Sukabumi students. This study used a quantitative approach with a quasi-experimental pretest-posttest one group test design method. The number of research subjects was 20 students of PGSD STKIP Bina Mutiara Sukabumi. The instruments used were a questionnaire for the statement of ecological intelligence indicators and an ecological intelligence questionnaire with the stages of the Project Based Learning (PjBL) learning model. The research data from questionnaire 1 shows the average score at pretest 50 and 73 at posttest and on the Ecological Intelligence instrument with its PjBL Stages obtained an average score of 37.75 at pretest and 52.2 at posttest, with each significance value 0.000 <0.05 then Ho is rejected, or there is an influence of the Project Based Learning (PjBL) learning model through hydroponic plants which is integrated with the implementation of social studies learning courses in elementary schools on the ecological intelligence of PGSD STKIP Bina Mutiara Sukabumi students.
