Abstract

ABSTRACTSpecial areas have a closed drainage system (existing drainage) when it rains there are still lots of puddles or runoff from the drainage that is not able to accommodate rainwater when it rains continuously, such as the incident in 2019 the Ancol Dreamland Park area could not accommodate rainwater. for a long time so that the Dream Park area flooded. The purpose of this study was to determine the planned rainfall, flood discharge, channel dimensions, and increase the water catchment area in the Ancol Dreamland Park area. The method used is by using Geopore ITB material. The results of this study showed that Q hydrology < Q Hydraulics Daily rain height plans for return periods of 2, 5, 10, 25, 50, and 100 years are 177.78 mm, 339.07 mm, 478.83 mm, 695.42 mm, 887.36 mm, 1107.69 mm and changes flow coefficient of 0.47 m3/s with channel dimensions 90 x 100 cm. to increase the water catchment area there are 13 channels throughout the Ancol Dreamland Park. So it can be concluded that flood control is carried out with 3 alternatives, namely changing channel dimensions, planning to change the flow coefficient, changing channel dimensions and geopore planning. Keywords: Drainage System, Geopori  ITB

Abstract

ABSTRAKTaman Impian Jaya Ancol yang terletak di pesisir pantai Jakarta Utara yang mempunyai magnet luar biasa terhadap masyarakat yang ingin menikmati keindahan pantai, namun disisi lain ada kendala yang dihadapi yaitu mengenai penyerapan air hujan dan aliran di wilayah pantai, pada tahun 2019 kawasan Taman impian sempat terkena dampak banjir yang melumpuhkan kegiatan wisata, akibat hujan yang mengguyur kawasan tersebut cukup lama.  Dengan demikian, perlu adanya perencanaan sistem drainase berkelanjutan yaitu merupakan sistem drainase yang bertujuan untuk mengurangi permasalahan yang ditimbulkan oleh adanya limpasan air hujan pada permukaan, untuk mengetahui hal tersebut dilakukan analisa drainase eksisting serta mengumpulkan data data yang berkaitan dengan kondisi wilayah dimaksud. Metode penelitian meliputi data intensitas curah hujan, menghitung kala ulang 10 tahun, 25 tahun, membuat skema drainase, mencari koefisien pengaliran serta mengetahui debit dan dimensi saluran sehingga dalam menerapkan perencanaan yang akan dilakukan berpijak pada kondisi lapangan yang sesuai dengan kajian. Berdasarkan kajian yang telah dilakukan, diperoleh model dan pembaharuan sistem pada kawasan Taman Impian Jaya Ancol dengan menggunakan material Geopori ITB untuk memperkecil koefisien aliran (C) dengan merubah perkerasan jalan dan paving dengan memanfaatkan material Geopori ITB yang sedang di kembangkan dan bisa diterapkan di kawasan Taman Impian Jaya Ancol.Kata Kunci: drainase berkelanjutan, geopori ITB, koefisien aliran.ABSTRACTTaman Impian Jaya Ancol which is located on the coast of North Jakarta which has an extraordinary magnet for people who want to enjoy the beauty of the beach, but on the other hand there are obstacles faced, namely regarding the absorption of rainwater and flow in the coastal area, in 2019 the Taman Impian Jaya area was affected the impact of floods that paralyze tourism activities, due to the rain that flushed the area for quite a long time. Thus, it is necessary to plan a sustainable drainage system, which is a drainage system that aims to reduce the problems caused by the presence of rainwater runoff on the surface, to find out about this, an analysis of the existing drainage and collecting data related to the condition of the area is needed. The research method includes data on rainfall intensity, calculating the flood return period of 10 years, 25 years, making a drainage scheme, looking for the coefficient of flow, and calculating the discharge and dimensions of the channel so that in implementing the planning that will be carried out, it is based on field conditions by the study. Based on the studies that have been carried out, a model and system update was obtained in the Taman Impian Jaya Ancol area using Geopori ITB material to reduce the flow coefficient (C) by changing the road pavement and paving by utilizing Geopori ITB material which is being developed and can be applied.Key words: sustainable drainage, geopori ITB,  flow coefficient.
