Abstract
Tummy time exercise involves positioning the baby on their stomach, allowing them to
support their body weight. The purpose of this study was to determine the effect of
tummy time exercise on gross motor skills in babies aged 3-6 months. This research
design employed analytics using a One-Group Pretest-Posttest Design approach. The
population consisted of 43 babies aged 3-6 months at the Integrated Health Service Post,
known as Posyandu, in Arjowilangun Village, Malang Regency. The sampling
technique was a total sampling. The time of intervention was 2 weeks. Data analysis
employed the Wilcoxon Signed Ranks Test. Before giving tummy time exercise
intervention, most respondents had normal gross motor skills (97.7%), and a small
proportion had delayed gross motor skills (2.3%). After intervention, all respondents
had advanced gross motor skills (100%). Based on the results of the Wilcoxon Signed
Rank Test, there was a significant influence on gross motor skills in babies aged 3-6
months before and after the intervention, as indicated by a p-value of 0.000 and a
calculated z-value of -6.487. In conclusion, tummy time exercises can significantly
increase gross motor skills in babies aged 3-6 months. Parents should apply tummy time
exercises to babies regularly to promote the development of gross motor skills in babies
aged 3-6 months, enabling them to achieve gross motor milestones more quickly.
