ABSTRACT
Jakarta's mangrove ecosystem is rapidly degrading due to human activities, underscoring the urgent need for targeted educational interventions aligned with the Sustainable Development Goals (SDGs). This study develops a project-based learning workbook for seventh-grade students in North Jakarta, addressing SDG 4 (Quality Education), SDG 13 (Climate Action), SDG 14 (Life Below Water), and SDG 15 (Life on Land). Designed using the ADDIE instructional model, the workbook integrates ecological content with structured learning to enhance students’ understanding of mangrove conservation while fostering critical thinking. Given mangroves’ role as carbon sinks and coastal protectors, the study supports SDG 13 by emphasising climate resilience. It also reinforces SDG 14 through marine ecosystem conservation and SDG 15 by promoting sustainable land management. Findings indicate that structured ecological education significantly improves students’ environmental awareness and attitudes. Expert validation confirms the workbook's effectiveness in cultivating proactive environmental stewardship, demonstrating education's pivotal role in driving sustainability.
