The Relationship Between Risk Factors in Dam Maintenance Work and Dam Maintenance Performance

Abstract

Dam maintenance is a crucial aspect of water infrastructure management to ensure its continued functionality in flood control, clean water supply, and irrigation. A number of dam failures, such as those at Situ Gintung and Cisadane Dam, demonstrate the importance of a risk-based maintenance strategy to reduce the impact of dam failures on society and the environment. This study aims to analyze the relationship between risk factors in dam maintenance work and the resulting maintenance performance. This study uses a mixed-method approach, with archive analysis to identify the main risk factors in five aspects (working methods, labor, equipment, materials, and the environment) as well as a survey of 30 professionals in the field of dam maintenance to evaluate their frequency and impact. Data analysis was carried out through Kendall Tau correlation test, factor analysis, linear regression, and multicollinearity test to determine the significant influence of risk factors on maintenance performance. The results showed that of the 38 risk variables identified, 31 were categorized as high risk, with 19 main categories having a significant impact on dam maintenance. The most influential risk factors are work method errors, labor limitations, and environmental factors such as sedimentation and erosion. Regression analysis shows that these risk factors explain 53.9% of the variability in dam maintenance performance. The implications of this study emphasize the need for the implementation of data-based risk mitigation systems, increased supervision, and strengthening of labor capacity to ensure the effectiveness of dam maintenance on an ongoing basis.
