Development of an interactive e-module of integrated science with the Connected type on energy topic for Junior High School (SMP) aims to develop an interactive e-module of integrated science that includes biology, physics, and chemistry concepts an interrelate unity in energy topics. That expected to strengthen the student concept knowledge. The Research and Development (R & D) design with the Plomp model was employed. Collection data procedures used validation sheets and user responses questionnaires by the validator team, teachers, and students. Assessments involved material substance, learning design, display (visual communication), and software utilization. Data analysis results showed the validation percentage from the material and media experts are 94.99% and 96.96%, with very valid criteria. Through the teacher's responses, obtain 95.00% (very good practicality criteria). The 92.45% on the one and one test and 92.71% on the small group test, both on very interesting criteria from students. Its means, the interactive e-module has been valid and suitable for use in the learning process.

Efforts to improve the quality of Integrated Science learning for junior high schools in the era of globalization that are following the challenges of 21st-century education can be done through the use of connected type interactive e-modules. The study was conducted to determine the effectiveness of the e-module on students' mastery of energy concepts. The research method used is a descriptive quantitative quasi-experimental type with a matching-only pretest-posttest control group design. The research was conducted in one of the public junior high schools in Bangkinang with a purposive sampling technique. Data were collected using research instruments in the form of mastery of concepts in energy material. Data analysis was performed using pre-requisite test, statistical test (different test; t-test), and N-Gain test. The results obtained show that the use of the connected type of integrated science interactive e-module can improve students' mastery of concepts on energy material in the experimental class with the medium category.
