Abstract

The need for E-LKPD is very high while the provision of E-LKPD is still lacking. This can be caused by various factors such as a lack of knowledge and skills of teachers in making E-LKPD, limited access to technology and software to create interactive E-LKPD, and a lack of resources. resources and funds to develop quality E-LKPD.This study aims to produce a mathematics learning tool in the form of Electronic Student Worksheets (E-LKPD) using the Problem Based Learning (PBL) model on material Construct curved side chambers for class IX SMP which are valid and practical. The development of the E-LKPD uses the ADDIE model which consists of five stages, namely the Analysis stage, the Design stage, the Development stage, the Implementation stage, and the Evaluation stage. The research instrument used a validation sheet and a teacher and student response questionnaire with data collection techniques using a Likert scale. The object of research is learning media with E-LKPD on curved side building materials for class IX. The test subjects were 37 students of class IX at SMP Negeri 25 Pekanbaru. The learning media products developed with the E-LKPD were validated by six validators consisting of two Lecturers of the Mathematics Education Study Program, two Lecturers of the Communication Sciences Study Program, two Lecturers of the Indonesian Language Education Study Program. Validation data and practicality data were analyzed by determining the average of each assessment. The results of the validation data analysis by six validators showed an average of 88.60% with the "very valid" criteria. The questionnaire assessment of the teacher's response to the use of learning media obtained an average of 97.5% with the practicality criterion, namely "very practical", and the average student response questionnaire obtained a value of 87.54% with the criteria of "very practical". Thus, it can be concluded that learning media with E-LKPD on curved side geometric shapes have tested their validity and practicality.
