This study aims to develop a Problem-Based Learning (PBL)-based Student Worksheet (LKPD) on corrosion material to enhance student motivation and learning outcomes. The development follows the ADDIE model: Analysis, Design, Development, Implementation, and Evaluation. Validation involved two experts, and trials were conducted with 30 students in class XII MIA 1 at SMAN 19 Gowa. Effectiveness was measured through motivation questionnaires and learning tests, while practicality was assessed through observation and response questionnaires. Results showed that the LKPD was highly valid, practical, and effective. Learning implementation was fully achieved, with positive responses from teachers and students. Student motivation and learning outcomes significantly improved, indicating that the developed LKPD is feasible as alternative teaching material.
