Analysis of Potential Application of Rainwater Harvesting System in Bedadung River Basin, Jember Regency
Bedadung watershed is one of the largest watersheds in Jember Regency, which is dominated by irrigated rice fields and often experiences floods. The flood can be reduced by increasing recharge with rainwater harvesting technology. The purpose of this study was to identify locations that have the potential to implement various rainwater harvesting in the Bedadung watershed. The work in this study was divided into four main stages: analysis and reclassification of rainwater harvesting criteria, multicollinearity test to find correlations between criteria, AHP method weighting analysis, and mapping of potential rainwater harvesting locations. Eight criteria can be used for site analysis based on the results of the multicollinearity test. The most significant weight of the criteria is elevation, and the smallest weight is land cover. Locations that have the potential for the contour mounds, harvesting rainwater from roofs and agricultural ponds are Kaliwates District, while the type of reservoir has potential in Ambulu District.
