Students of Educational Informatics Engineering of State University of Yogyakarta have frequency and duration of laptop use that is higher than students from other departments have. Laptop
use which does not properly fit with ergonomical standards may lead to specific adverse health
impacts. The purpose of this study was to determine the relationship between duration, frequency, laptop size, and position of laptop use and the musculoskeletal complaints among those students. The research method was survey with cross sectional approach. The research sample
was 86 students from semester IV and VI who were selected by accidental and purposive sampling techniques. The data were collected by using a questionnaire and furthermore were analysed with chi-square and contingency coefficient at 95 % level of confidence. The results show
that only 7,0 % respondents used laptop in low-duration, only 1,1 % used laptop in low-frequency, only 3,5 % used large sized laptop, and only 9,3 % used laptop with good position. There
were 45,3 % of respondents who had moderate musculoskeletal complaints. Parts of the body
which were most complained are neck, shoulders, and waist meanwhile the least ones are elbows and arms. From the statistical analyses it is identified that laptop use position has the
strongest relationship with the disorders (contigency coefficient = 0,348 and p-value = 0,064). It
is advised that information regarding with the correct use of the laptop and the impact of the unergonomical laptop use have to be socialized among the students in order to avoid them from
unwanted health problems risk.
