The Indonesian Traditional Game Museum is a three-story museum with two basements located in Tanah Abang, Jakarta. This museum is located near the Cideng river. This museum is built based on Peraturan Pemerintah Republik Indonesia No. 66 tahun 2015 about museum that has some functions to protect, to develop, to exploit collections, and to be able to communicate the meaning of the collection to the society. One of the collection that has to be preserved is Indonesian games, both means of play, the game itself, as well as knowledge of the game. The final project of the drainage design of the museum aims to obtain a drainage design in accordance with the provisions of the Permen PU No. 12 year 2014. This Final Project includes several stages, namely hydrological analysis, flood analysis using modeling from HEC-RAS, dewatering analysis, and designing drainage facilities and infrastructure. Hydrological analysis is carried out to obtain the distribution of rain which will be used to find certain return period rainfall. The rainfall obtained will be used to design drainage and also as one of the requirements in the analysis of flood peil. Flood discharge with a 25 year return period with outlets in front of the museum is Q = 66.74 m3 / s. Drainage design is carried out by observing the design of museum buildings and existing land use. The channel is designed to have 14 segments connected to two outlets, namely north and south outlets. Drainage channels are made using precast or U-Ditch concrete and culverts with cross sections in several parts. The biggest cross section used is U-Ditch type 60 x 80 x 120. Gutter rain consists of horizontal gutters and upright gutters. The calculation results show that the channel bottom elevation in both outlets is above the river flood level, so there is no need for a sluice gate. As part of maintenance, control boxes will be made at several points of the drainage channel.
