PENGEMBANGAN MEDIA PEMBELAJARAN KIT PRAKTIKUM DALAM MATERI ELEKTROKIMIA YANG BERKAITAN DENGAN JEJAK KARBON UNTUK MENINGKATKAN KOMPETENSI ESDRENI PUSPITAADININGTYASauthorIntegrated Instrument Component (KIT) is a box containing practical equipment in the form of tools and materials containing certain materials. The tools and materials used in KIT are environmentally friendly materials. In addition, KIT is also equipped with a practical manual for instructions on use. The purpose of this study is to develop, determine the feasibility and student response to the Practical KIT in electrochemistry material related to carbon footprints to improve ESD competency. This research method uses a Research and Development design with the ADDIE model (Analyze, Design, Development, Implement, Evaluation). Data collection techniques are carried out through validity tests and limited trials. The validity test to determine the feasibility uses the Aiken V index of 0.87 for the Practical KIT material and media which are validated by 5 validators. A limited trial to determine student responses uses a sample of 1 class XII of high school involving 30 students. The validity results are declared valid with an average value of V for material validity of 0.88 and media validity of 0.89 as well as the results of limited trials with student response results of 84% with a very good category. Therefore, the developed Practical KIT meets the criteria for validity and is suitable for use in learning.L Education (General)LB Theory and practice of educationLB1603 Secondary Education.
