Cilacap is one of the regions in Indonesia in the southern coastal region bordering the Indonesian Ocean. In the coastal areas of Cilacap including Kawunganten district, there are frequent floods due to sea level rise. Tidal flood problem in Cilacap can be overcome by constructing a moveable dam. The selection of moveable dam gateis needed so that it can be work optimally. Data in this study were obtained through a questionnaire and distributed to respondents who were experts in the field of water. There are 5 criteria used to select the type of moveable dam gate, namely material, function, operational and maintenance, cost and location. There are 4 alternatives of moveable dam gatenamely flap gate, radial gate, sliding gate and rubber dam. The results of the questionnaire were then processed using Analytical Hierarchy Process. The results showed that the most important criteria to select the type of moveable dam gate is cost (0.273). The best alternative of moveable dam gate based on all criteria is flap gate (0.291). Movable dam with flap gate became the priority because it is easy to operate and low cost. The best location for moveable dam placement is before Ujungmanik Bridge with a score 0.376.

Cilacap是印度尼西亚南部沿海地区与印度尼西亚洋接壤的地区之一。在包括 Kawunganten 区在内的 Cilacap 沿海地区，由于海平面上升，经常发生洪水。Cilacap 的潮汐洪水问题可以通过建造一个可移动的水坝来解决。需要选择可移动的坝闸，以便它可以最佳地工作。本研究中的数据是通过问卷调查获得的，并分发给水领域专家的受访者。选择活动坝闸的类型有5个标准，即材料、功能、运行和维护、成本和位置。活动坝闸门有翻板闸门、径向闸门、滑动闸门和橡胶坝4种可供选择。然后使用层次分析法处理问卷的结果。结果表明，选择活动坝闸类型的最重要标准是成本（0.273）。基于所有标准的可移动坝闸的最佳替代方案是翻板闸 (0.291)。带翻板闸门的活动坝因其操作方便、成本低而成为优先考虑的因素。可移动大坝放置的最佳位置是在 Ujungmanik 桥之前，得分为 0.376。
