ABSTRACT

This research intends to analyze the correlation of factors, variables, and aspects in the modeling of sabo dam capacity. Multiple parameters are influencing the sabo dam capacity modeling. It can be determined by defining and testing the new indicators through statistical validation. Therefore, this approach will always be opened for a new indicator that may be potential to be adopted and qualified by passing the statistical test that may enrich the overview of the capacity modeling. In one of the established models, several sabo dam indicators are grouped in three aspects of physical, regulation and social. These indicators are expected to have a strong interconnection to the capacity of a sabo dam. The capacity itself is not yet included in the sabo dam performance model. The compatibility of the capacity indicator needs to be verified within the mathematical structural model of sabo dam performance. Then, the indicators magnitude is collected and its value is scaled through site survey. The methodology is to construct the structure with the added capacity indicator that is assembled and its interconnection strength is tested within the structural mathematic equation which is connecting every parameter in a specific correlation to describe the modeling in a general overview. The adoption of this model is built up using the previous studies' dataset. The result shows that the capacity indicator adopted the model resulting in compatibility as R²: 95.32% and adjusted R²: 84,41%. By the conclusion, it will simplify and reduce the number of indicators from forty to only nineteen that may simplify in applying real survey to find the actual capacity value of a sabo dam.
