SUMMARY
The lack of self-regulated learning of a learner in a series of learning activities often hurts the achievement of their learning outcomes. It is necessary to provide a learning environment that supports an increase in one's self-regulated learning, which is through the application of blended learning. This study aims to look the effectiveness of the application of blended learning using the Moodle LMS in improving Polytechnic students’ self-regulated learning. This study applies a quantitative approach through the pre-experiment method and uses a One-Group Pretest-Posttest research design. This study compares the results of pretest and posttest on experimental class students after applying blended learning using the Moodle LMS. The research instrument analyzed was in the form of a non-test instrument which was arranged in a questionnaire. Statistical tests on research data were processed using SPSS 26 software. Wilcoxon nonparametric test results on questionnaire data gave results in the form of a significance value of 0.00 < 0.05 and the average N-gain value showed a value of 0.64. Through the results of statistical tests that have been carried out, it can be concluded that the application of learning with the blended learning model using the Moodle LMS has implications for increasing self-regulated learning for Polytechnic students with moderate effectiveness criteria.
