Abstract
In the flood management, one way to reduce the volume of flood is by using polder system. This system is implemented by The Government of DKI Jakarta Province with retention ponds in some area. To keep its function, some routine maintenance with appropriate budget of each polder are running, but there are some conditions which give impact to the polder functions and services. There are many aspects that contributed in the decreasing of polder service capability. In other hand, Water Resources Agency of DKI Jakarta Province, who is responsible for the maintenance of those polders, does not have any guideline to evaluate the polder service and correlate it with appropriate maintenance budget. This research analyzed seven selected polders in DKI Jakarta with 41 various variables and indicators that used to evaluate polder services, which are 4 technical variables (Tx) with 17 indicators (tx) and 5 non-technical variables (NTx) with 15 indicators (ntx). As the result of this research, evaluating the polder services are more precisely by using 36 various variables and indicators, which are 4 technical variables with 15 indicators and 5 non-technical variables with 12 indicators. These variables and indicators then could be used to evaluate the polder-s service.
