This research is a Research and Development study which aims to produce contextual mathematics LKPD products using Banyumasan batik motifs on material transformations in valid grade IX junior high school. The development model in this study uses this 4-D model popularized by Thiagarajan, and Semmel & Semmel which consists of four stages namely Defining (Define), Designing (Design), Development (Develop), and Deployment (Dessiminate). At the stage of development (Develop) has been produced contextual mathematics LKPD using Banyumasan batik motifs on material transformation in class IX junior high school. The validity level of the LKS gets valid criteria with the average value of the three validators being 3.54, the teacher's response to the LKPD gets a good criterion of 4.5 while the student's response to the student worksheet responds well with the a + b option having an average of 61.33%.
