The data analysis techniques used were validity, practicality, and efficacy. The results of this study obtained that from the validation results, the character-loaded sun blog math website media on the material of the two-variable linear equation system achieved a level of validity with highly valid categories with media validity reaching 98.1% and material validity reaching 96.3%. For the results of questionnaire practicality teacher and student responses achieved a level of practicality with very practical criteria was demonstrated with the student response questionnaire achieving a score of 96 % and the teacher administered response questionnaire achieving a score of 88%.
