Abstract: Polders were one of the construction that built to minimize the impact of flood, because polders have pond to create a room for water as one of the method in flood risk management. Polders usually build in low land area where water could not flow by gravity with components inside of it, which are pond, pumps, water gate and trash racks. Many cities in Indonesia has already build polders to manage the flood in an area, such as DKI Jakarta, Semarang, Bandung, East Kalimantan and others. To maintain those polder’s function, need an effort and government’s consistency to regulate activity and maintenance cost of each polder. Guideline to find out the service index of those polder are not yet available. This guideline will become important to make prioritize of managing polders. This research analyze technical and non-technical indicators would give impacts to polder’s function and formulate the service of polder system for assessment purposes. As points of this research, eight polders in DKI Jakarta which have complete components were chosen for modelling. The result of this research are technical component are mostly effected to polder system operating than non- technical component. Its proportion are 53% technical aspect and 47% non-technical aspect.
