KAJIAN OPERASIONAL SISTEM POLDER UNTUK PENANGANAN BANJIR DAN ROB DI KAWASAN GENUK SEMARANG

Abstract

<p>The Kaligawe Genuk area is the main route for the North Coast (Pantura) of Java.<br />The area is the gateway to the city of Semarang from the east direction. Since 2005,<br />this area has frequently had floods caused by tides (tidal floods) and rainfall. The<br />Central Government, supported by the Semarang City Government, built the Kali<br />Tenggang and Sringin Polder systems from 2016 to 2019. In terms of capacity, this<br />system is not yet perfect for dealing with floods, and it requires efforts so that the<br />system can be operated optimally. This study activity aims to simulate rainfall flow<br />rate, the pump capacity, and the retention pond. The simulation results will become<br />the basis for the development of the polder system operational manual. The<br />implementation method collects secondary rainfall data, reviewing the condition of<br />a catchment area, retention pond, and pump station. Focus group discussion with<br />stakeholders done in the Kaligawe Genuk area. The location of the activity is more<br />focused on the Kali Sringin area. This study produces tables and graphs of pump<br />capacity simulation, retention ponds, and an operational manual for the Sringin<br />Polder system. It is hoped that this guideline will become the basis for the polder<br />system's sustainable operations.</p>
