DETERMINING HEIGHT BASED ON HAND LENGTH IN TOBA BATAK TRIBE STUDENTS

Abstract

Indonesia is famous for being a maritime country or the largest archipelagic country in the world that has a diversity of terrain. Geologically, Indonesia is the meeting area of 3 large tectonic plates, namely the Indo-Australian plate, Eurasia, and the Pacific plate. The Indo-Australian plate collides with the Eurasian plate off the coasts of Sumatra, Java and Nusa Tenggara, while with the Pacific north of Irian and North Maluku. This geographical location can be the cause of various natural disasters such as volcanic eruptions, earthquakes, tsunamis, and so on. Not only natural disasters, crime cases also bring fatalities. According to data reported by the Central Statistics Agency, in 2022 there were 372,965 cases of crime, often found bodies in a state of decay, heavy damage or in the form of body pieces that sometimes only left a few parts of the body to be examined and identified. Methods: This research is an analytical research with a cross-sectional design, with the aim of finding the relationship between the free variable (hand length) and the dependent variable (height) in the Batak ethnicity.
Results: right and left hand length in males and females had a significant relationship with a p-value < 0.005 (p = 0.001), with a correlation rate varying from moderate to very strong r = 0.557 – 0.876
Conclusion: hand length has a relationship with height with a moderate to very strong correlation so that hand length can be used as a good predictor of height.
