The Incidence of Computer Vision Syndrome toward Rubber Tyred Gantry Operator in Container Surabaya Terminal

The use of Visual Display Terminal (VDT) in addition to providing benefits to facilitate the work also can have an impact on health, one of which is the eye health problems. On the eye syndrome experienced by workers during VDT work with for a long time called Computer Vision Syndrome (CVS). Factors associated with the occurrence of CVS were age, years of service, long break interrupted VDT use, distance to the VDT, high monitor to eye with a horizontal line. This research is to identify the major risk of the relationship between ages, years of service, long break interrupted VDT use, distance eyes to VDT, high monitor to eye with a horizontal line on the operator Rubber Tyred Gantry (RTG) to CVS incidents in Surabaya Container Terminal. This study is an observational study using cross sectional design. The total respondent amounted to 34 people. This study was population study. All RTG operator was taken as respondent. Data were collected through an interview guide (interview), Body Map Nordic questionnaires and medical examinations. Data were analyzed with descriptive statistics, correlation and binary logistic regression analysis. The results showed that 58.8 % of respondents experienced CVS. Statistical analysis of the risk factors found associated with the variable age CVS odds ratio =14 (95 %CI=2, 37-82, 71), variable working time odds ratio =11 (95 %CI=2, 51-56, 09), the old variable break interrupted VDT use odds ratio =7 (95 %CI= 1, 29-41, 65), the variable distance to the VDT odds ratio =16 (95 %CI = 1, 73-145, 78), high variable monitor to eye horizontal line odds ratio =4 (95 %CI = 0, 55-23, 24). The variable distance to the VDT is the most risk factors for experiencing incidents CVS on RTG operator at Container Surabaya terminal.
