Subjects and Method: This study was a quasi-experimental, control group pretest-posttest design. The sampling technique used was purposive sampling, and as many as 32 postpartum mothers who experienced fatigue were involved in this study. This study was divided into 2 groups, namely the experimental group with the provision of pilates exercises and lavender aromatherapy, and the control group without treatment as a comparison. The independent variables of this study were pilates exercises and lavender aromatherapy. The dependent variable was postpartum maternal fatigue. The data analysis used is the Wilcoxon test and the Mann-Whitney test. Results: Analysis using the Mann-Whitney statistical test showed significant results with test results (p-value <0.05). From these results, it was found that there was a significant difference in the respondents of the experimental posttest group and the control posttest group. Conclusion: Pilates exercise and lavender aromatherapy have an effect on the level of fatigue reduction in postpartum mothers in the experimental pretest-posttest group in the Andong Health Center work area.
