description: In several areas in Indonesia, it is often found that community groundwater and river water during the dry or rainy season does not meet the quality standards for safe drinking water, and in certain locations the water is even unfit for consumption because it is turbid and mixed with mud. Clean water is very important for human life. This research aims to create a water purification tool using coagulation and adsorption methods, determine the effect of these two methods, develop LKPD, carry out feasibility tests and determine students' responses to the media being developed.This research uses the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The water purification tool and learning worksheet developed were tested on 30 class XI students. Validity tests were carried out on the water purification equipment and LKPD based on the assessment of material experts, media experts and student responses. The LKPD research instrument for water purification using the coagulation and adsorption method is a validation sheet using a Likert scale which includes content feasibility aspects, presentation feasibility aspects, linguistic aspects, green chemistry aspects and graphic aspects. Aspects of suitability of the tool, practical aspects of the tool, and aspects of usefulness. The research results based on expert assessment obtained a percentage of 0.92% for the appropriateness aspect of the content, 0.90% for the presentation aspect, 0.91 for thelinguistic aspect, and 0.92% for the green chemistry aspect, 0.94 for the graphic aspect. Meanwhile, student responses received an overall average percentage of 82% with the "very good" category. Thus, it can be concluded that the water purification tool and LKPD for water purification using the coagulation and adsorption method are declared valid and suitable for use in the learning process.
