Abstract

Chemistry learning can be achieved by providing learning resources that are able to provide motivation to students, so that they can understand the material regularly and systematically. These student activities can be designed well and directed in Student Worksheets (LKPD). The aim of this research is to examine the validity of student worksheets (LKPD) based on discovery learning on the material of analyzing the trajectory of changes in pH of several indicators extracted from natural ingredients. The type of research used is development research or Research And Development (R&D) according to Sugiyono. The results of this research show that the LKPD developed is very valid, with the average value of the three material expert validators in stage 1 validation being 71.14% and stage 2 validation increasing to 100% and the average percentage value of the three media expert validators in stage 1 was 88.88% and 100% in validation stage 2. This shows that the LKPD developed is suitable for use in the field
