Sizing System for Indonesian Policewomen’s Body Armour

Abstract

Existing body armour sizes are focused on male users, as they are the majority of the population. The personal equipment of female and male soldiers should be separated because these groups have different sizes and matches. In other words, body armour design should correspond with user anthropometry. Good body armour must fit properly and be comfortable for the users. To solve this problem, this study develops a new sizing system. The study’s subjects were 150 with 20-to-30-year-old policewomen working in the Regional Police Department of Special Region of Yogyakarta. Data collection was performed with the simple random sampling method. Two statistical analysis methods, Principle Component Analysis (PCA) and clustering, were used to assist with the assessment of data. Analysis of the subjects indicated 15 size groups for body armour in three larger groups: S (VS, S, N, L and VL), M (VS, S, N, L and VL), and T (VS, S, N, L and VL). All size groups were validated using Euclidean distance, with an accuracy result of 66.67%.
