Abstract

Curriculum change has become inevitable. Moreover, the very rapid development of science and technology no longer allows the education sector to remain with the existing curriculum, namely the 2013 Curriculum, for an extended period. The implementation of the Merdeka Curriculum must take into account the readiness of educational institutions. Teachers must also prepare themselves for the implementation of the Merdeka Curriculum. Teaching resources available on the Merdeka Mengajar Platform (PMM) are still limited, particularly project-based learning modules. Based on direct observations and questionnaires administered to Grade 10 biology teachers at SMAN 1 Batauga, South Buton, Southeast Sulawesi, it was found that teaching materials—especially project-based learning modules—represent one of the shortcomings in biology learning. The material selected for the development of the biology learning module was ecosystems, as it is well suited to the Project-Based Learning (PjBL) model. This research and development study aim to produce a biology learning module on ecosystem material, specifically the mangrove ecosystem subtopic, based on Project-Based Learning (PjBL) at SMAN 1 Batauga. The results of the research and development of the mangrove ecosystem learning module using the ADDIE model were determined based on validity and practicality tests. The validity test results showed a score of 82%, indicating that the module is feasible for use as teaching material. The practicality test based on teacher questionnaires showed a score of 91%, while the student questionnaire results yielded a score of 84.13%, both of which fall into the very practical category.

The practicality test based on teacher questionnaires showed a score of 91%, while the student questionnaire results yielded a score of 84.13%, both of which fall into the very practical category. The implementation results based on practicality tests through teacher and student questionnaires indicate that the learning module on the mangrove ecosystem subtopic is categorized as very practical.
