description: In this 21st century, the world of science, technology and education in the international arena is experiencing very rapid development, so that students are required to prepare themselves for the advancement of the world of education. Especially in chemistry learning which studies many phenomena in the environment around students including problems related to chemical concepts. Thus, this study aims to determine the development, feasibility and response of students to the development of PBL-based e-LKPD on high school chemistry laboratory wastewater treatment.  This e-LKPD development uses the ADDIE model, namely Analyse, Design, Develop, Implement, Evaluate. Data collection techniques were obtained from a learner needs analysis questionnaire, validation sheet, learner response questionnaire and learner activity implementation sheet. Assessment was carried out at the validation stage using 5 media expert validators and 5 material expert validators with the Aikens value calculation index. Based on the results of material validation obtained 0.83 and media validation 0.84. The results of the assessment on both aspects of validation can be stated that the PBL-based e-LKPD on high school chemistry laboratory wastewater treatment is valid and feasible to use. The results of the student response questionnaire obtained a percentage value of 90% in the “Very Good” category and it can be stated that the e-LKPD media is very feasible to use in learning chemistry regarding high school chemistry laboratory wastewater treatment.
