Development of Chemistry Comics as Alternative Learning Media on Electrolyte and Non Electrolyte Solution for Grade X SMA

This study aims to produce a media as alternative learning media of chemistry comic on the material Electrolyte and Non Electrolyte for grade X of SMA and determine of the validity and practicality of resulting media. The type of research used research and development (Research and Development / R&D). The development model used 4-D (Four D Models), consisting of four stages, namely define (pendefenisian), design (perancangan), develop (pengembangan) and desiminate (penyebaran). This research determines the level of validity and practicality of the developed chemistry comic media. The media of chemistry comic was validated by two chemistry lecturers from FMIPA UNP and two chemistry teachers from SMAN 2 Payakumbuh. Determination of the practicality level of chemistry comic media by three chemistry teachers from SMAN 2 Payakumbuh and 27 students of Class X MIPA 1 SMAN 2 Payakumbuh. The instrument used was a questionnaire of validity and practicality. The results of the validity questionnaire analysis obtained a very high level of media validity with a kappa moment value of 0.85. While the practicality analysis results based on the teacher and student response questionnaire received kappa moment values of 0.93 and 0.88 respectively, with a very high practicality category. It can be concluded that the chemistry comics made can be used as learning media on Electrolyte and Non-Electrolyte Solution material for grade X SMA.
