Tingkat Risiko Bencana Banjir di Kota Bandar Lampung dan Upaya Pengurangannya Berbasis Penataan Ruang

Abstract

In the past ten years (2010-2019), Bandar Lampung has experienced 26 disasters, and 14 of them were floods. The flood that occurred in the city of Bandar Lampung is a serious problem, because in recent years the city of Bandar Lampung has always been hit by floods during the rainy season. Therefore, the purpose of this study is to identify the level of risk of flooding in the city of Bandar Lampung and to recommend spatial-based reduction efforts. This study uses a combination analysis approach between qualitative and quantitative analysis. The level of flood risk identified in this study is calculated based on Regulation of the Head of BNPB Number 2 of 2012 concerning General Guidelines for Disaster Risk Assessment. From the research results, it is known that Bandar Lampung City has three classes of flood risk, namely low, medium and high risk. The area classified as low risk is 11,460.96 ha or about 62.37% of the total area of Bandar Lampung City. Meanwhile, the area classified as high risk is 3,781.12 ha or about 20.58% of the total area of Bandar Lampung City. The main factors affecting the risk level of floods are hazard, vulnerability and capacity. To reduce the risk of floods in Bandar Lampung, effective efforts are needed through spatial planning, spatial use and spatial use control.
