Abstract
Height measurement is one among other means to monitor the growth and development of children. Height measurement is carried out in various parts of the world for this purpose. This study wanted to find out how growth in height and neuro-muscular reaction time --NMRT of female students, especially in the Tengger Mountains area, Pasuruan; and the coastal area of Kenjeran, Surabaya. Both have different contrast environments. Measurements were made on 273 female students aged 10, 11, 12, and 13 years. Height was measured using a standardized anthropometer. The NMRT was measured using a ruler that is dropped suddenly and must be captured by the female students. t-tests was carried out on these measurements to determine whether they have significant differences. The results showed that there were significant differences in height at ages 11, 12, and 13 years. Significant differences in NMRT occurred at 12 and 13 years of age. We conclude that growth on female students in Tengger and Kenjeran differed significantly in height and NMRT, but the significance of these differences began at different ages. The NMRT differs more slowly. It is suspected that the quality of life in the Tengger Mountains area is not as good as the Kenjeran Coastal area, but it we need to study further.
