The validation has been validated by three chemistry lecturers at UNP, two Payakumbuh SMAN 3 chemistry teachers, and a chemistry teacher of Payakumbuh SMA N 5 schools. Validation of the module using Cohen's Kappa formula. The yield with a kappa moment value of 0.90. Practicality sheets were given to 58 students. The result of the practicality has a very high validity level of 0.90. © Published under licence by IOP Publishing Ltd.
