Analysis of the Influence of Priority Scale Criteria on Improving Drainage Function in Serang City with DPUPR Performance as an Intervening Variable
Downloads
The rapid population growth and urban development in Serang City have significantly increased the incidence of flooding, highlighting the importance of improving urban drainage systems. This research analyzes the influence of priority scale criteria—technical, economic, inundation, socio-cultural, and environmental—on the enhancement of drainage functions in Serang City, with the performance of the Public Works and Housing Agency (DPUPR) as an intervening variable. The study uses a quantitative approach with data collected through expert validation and public surveys, analyzed using Structural Equation Modeling-Partial Least Square (SEM-PLS) and multiple linear regression. The findings reveal that the technical and inundation criteria have the most significant direct influence on drainage function improvement. Moreover, the performance of DPUPR mediates the relationship between priority criteria and the success of drainage improvements. The study proposes alternative strategies based on dominant influencing factors, providing a practical reference for urban infrastructure planning and flood mitigation efforts in Serang City.
