But in reality students still tend to be passive in learning and are not accustomed to constructing their own knowledge. The teaching materials used are printed books from erlangga and LKPD from publishers. The absence of LKPD development from educators is due to the limitations of educators in utilizing technology and time constraints in designing attractive LKPD. This resulted in the absence of a valid and practical LKPD. This study aims to create an LKPD based on a valid an Realistic Mathematics Education (RME) teaching methide, for grade XI hight school students. This type of study is a design study using the plomp development model, which includes needs analysis, program analysis, concept analysis, and student analysis. The prototyping phase consists of steps taken in the design of the LKPD. In step 1 of the prototype, a process of self-assessment is performed (self-evaluation). In prototype 2, an expert review was performed, which was then assessed by the experts to obtain a valid prototype. In phase 3 of the prototype, an individual assessment was performed by testing LKPD on 3 students with heterogeneous qualifications. During prototype 4 phase, a small group evaluation was conducted on six students with heterogeneous ability levels, to determine the practicality of the LKPD.
