Developing Teaching Material on Report Text of Observation Results Concerning Green Industry as Scientific Awareness for Senior High School Students

Lately, energy sustainability has become an acutely disputed issue, both at national and global scale. To keep up with the phenomenon, students need to accrue their scientific awareness to innovate in the Green Industry corridor. This research is a development research applying a 4D model (Defining, Designing, Developing, and Disseminating). Based on expert validation and empirical validation, the applicability of the teaching materials under development was 92%. On the other hand, based on the calculated results of the results of product tryouts, the applicability was found to reach 91%. The effectiveness, as found in test using Paired Sample T-Test, generated the value of t = 12.465 with a significance level of 0.000 (p <0.05), corroborated with a mean difference of 3.0625. The posttest mean was 84.7188 with SD 2.96468, while the pretest mean was 81.6563 with SD 3.16849.
