<![CDATA[This study aims to analyze the effectiveness of mindfulness based on deep breathing techniques in improving emotional regulation abilities among university students who often face academic and social pressures. A total of 12 students in Samarinda were divided into two groups: experimental and control. The experimental group underwent a mindfulness training based on deep breathing for five consecutive days, with each session lasting 30 minutes. The study employed a pretest-posttest control group design, using the Emotion Regulation Questionnaire (ERQ) as the instrument. Statistical analysis showed a significant improvement in emotional regulation in the experimental group before and after the intervention (t = -3.824, p = 0.012). Additionally, the experimental group showed a significant difference compared to the control group (t = -2.398, p = 0.037), with a mean difference of -8.333. These findings confirm that mindfulness training based on deep breathing is effective in enhancing emotional regulation in students, and can help them manage academic and social pressures more adaptively ABSTRAK Penelitian ini bertujuan untuk menganalisis efektivitas mindfulness berbasis deep breathing dalam meningkatkan kemampuan regulasi emosi mahasiswa yang sering menghadapi tekanan akademik dan sosial.
