STUDI EVALUASI & PERBAIKAN SISTEM DRAINASE DI POLDER JATI PINGGIR KANAL BANJIR BARAT DKI JAKARTA
Abstract
Abstrak : Polder Jati Pinggir sebagian besar terletak di Kelurahan Petamburan yang merupakan pemukiman padat. Disamping permasalahan sampah, banjir tersebut juga disebabkan oleh sistem drainase yang mengalami penurunan fungsi dan kondisi fisik bangunan, seperti adanya penutupan saluran drainase di beberapa lokasi. Maksud dari studi ini adalah untuk mencari alternatif penanganan banjir yang terbaik melalui pendekatan parameter hidrologi dan hidrolika di Polder Jati Pinggir. Tahapan penelitian pada studi ini adalah Pembentukan Zona, Pembentukan Sistem Pengaliran, Evaluasi Kapasitas Saluran, Penentuan Kebutuhan Perbaikan, Alternatif Penambahan Kapasitas Pompa, Alternatif Sumur Resapan.
Hasil penelitian menunjukkan bahwa kapasitas eksisting di beberapa ruas saluran tidak dapat menampung debit rencana sehingga perlu dilakukan penanganan banjir dengan peningkatan kapasitas saluran dan penambahan kapasitas pompa.

Abstract : Part of Jati Pinggir Polder is located in Petamburan Village where is as a crowded resident. Flooded every year is caused by the condition of garbage which is piled in drainage channel. In addition, the flood is caused by the decreasing of drainage system function and structure physical condition such as the sedimentation and there are some covering of drainage channel in some locations. This study intends to find the alternative of accurate flood handling therough the approach of hydrologic and hydraulic parameter in Jati Pinggir Polder. The steps of research are as follow: zona forming, flow system forming, evaluation of channel capacity, determination of imoprovement demand, alternative of adding the pump capacity and penetration well. Results shows that some sections of drainage channel have the existing capacity under planned capacity and increase pump capacity.
