        abstract = {Learning in SMK has not touched much material that is appropriate to the vocational field. Vocational mathematics,
especially on matrix material, has not shown the range of applied mathematics material based on initial observations
of electronic books. This results in them not having the ability to meet the requirements because the material provided
does not help students make connections with their world. This study aims to realize mathematics teaching materials
based on applied mathematics on matrix materials that are valid, practical, and effective. The research method used
is the Research and Development (R\&D) ADDIE model with 5 stages. The research was conducted at SMKN 1 South
Tangerang. The research instrument includes a material expert and media expert validation sheet, a questionnaire on
the practicality of teaching materials by the teacher, and a student response questionnaire to teaching materials. Based
on the research, the results of the validation of teaching materials by material experts and media experts with an
average percentage of 84.12\% (Very Eligible), teacher responses with a percentage of 88.70\% (Very Good), and
student responses to teaching materials with an average percentage average 74.10\% (Good). These findings explain
that mathematics teaching materials based on applied mathematics on matrix materials are valid, practical, and
effectively used. Validity is assessed by experts with aspects determined by BSNP, practical depending on the
teacher's opinion, and effective is determined by student experience with responses to teaching materials.},
