PRIORITAS REHABILITASI LUMBUNG AIR DI KABUPATEN PATI DENGAN MULTIPLE ATTRIBUTE DECISION MAKING

Abstract

Water security has become a global issue, especially in sustainable water resources management. It is closely related to the need for clean water, which is critical, limited, and vulnerable. Some factors that lead to problems in water security are population growth, climate change, and water resources management, which involves many parties and has not been optimized in many places. The Central Java region, especially Pati Regency, is an area that is vulnerable to water security problems, particularly drought. Water granaries in Pati Regency are one of the solutions to overcome drought problems. However, water granaries in Pati Regency have not functioned optimally. Thus, it is necessary to determine the priority order in rehabilitating water granaries using the Multi-Attribute Decision Making (MADM) method. The research was conducted by examining fourteen alternatives influenced by six criteria. The results show that physical infrastructure an important role in determining the priority order of rehabilitation of water granaries in Pati Regency. The results revealed that the Raci water granary was the priority in rehabilitation and had the highest preference value. The SAW method was optimal in determining the priority order of rehabilitation of water granaries in Pati Regency with an RMSE value of 3.648. It is necessary to review the weight of the performance assessment of water granaries to make decisions and follow up on water granary rehabilitation that can be carried out appropriately and beneficially for the community.
