Mismatch Analysis of Elementary School Desk and Chair Using Monte Carlo Simulation

Abstract

In this paper, we analyze the mismatch between the desk and chair key characteristics and pupil’s anthropometric data. Samples were taken from public elementary schools in six regions (Surakarta, Sukoharjo, Sragen, Karanganyar, Boyolali, and Klaten) of Central Java Indonesia. Mismatch comparisons are made among existing desk and chair, Indonesia National Standard (SNI) dimensions, and the dimensions from pupil’s anthropometric data. Monte Carlo simulation method is used to find the smallest mismatch among the anthropometric percentiles data. From the analysis of simulation result using Crystal Ball software, seat width and under desk clearance have the lowest mismatch. The seat height and desk height from desk and chair dimensions from pupil’s anthropometric data have the lowest mismatch comparing to the existing and SNI desk and chair dimensions.
