This study aims to develop an E-LKPD based on argument mapping for waste-handling sub-materials to improve students' argumentation skills. The R&D is used to create the E-LKPD with the ADDIE (Analyze, Design, Development, Implementation & Evaluation) design.-based E-LKPD was Argument mapping implemented at SMAN 04 Bogor for students of class X MIPA 6. The results of expert validation on media and materials. E-LKPD based on argument mapping showed that the results were suitable for use and an expert validation of questions to hone students' argumentation skills. Those are very decent results. The effectiveness of the argument mapping-based E-LKPD is seen from the increase in the level of students' argumentation which is analyzed with the Toulmin Argumentation Pattern (TAP) argumentation level criteria in the posttest is an increase in the percentage of students' argumentation at levels 4 and 5. At the same time, there is a decrease in the percentage level of students' argumentation at level 2, and These 3 things show that argument mapping can improve students' argumentation skills by increasing the N-Gain with a value of 0.61 which is included in the quite effective category because (g) > 0.30.
