Abstract
The land use change from agricultural to industrial city took place in Karawang. Besides land conversion, transfer in water usage also increased for industrial needs. This is caused by poor water management in terms of distribution and control of water usage, mainly in the industrial and agricultural sectors. The area of irrigated land was reduced from 97,037 ha (2009) to 90,062 ha (2017), while the amount of dry land increased from 22,063 ha (2009) to 46,299 ha (2017). It showed that the lack of irrigation water management has an impact on the reduction of productive paddy fields. Therefore this research aims to formulate an action plan of water irrigation management. The study was conducted in West Telukjambe District, Karawang Regency. The method used stakeholder analysis and system dynamics modeling. Data obtained from observation and interview data, irrigated land area, and the amount of irrigation water availability. The results showed the overlapping and missing roles of several stakeholders in charge of irrigation water management in West Telukjambe. Model simulations showed the increasing of irrigation serving area for additional management performance of each stakeholder. Therefore, integrated management of irrigation systems needed to control the distribution and water irrigation efficient.
