ABSTRAK

Wilayah yang paling parah terkena bencana banjir luapan Bengawan Solo di Kab. Lamongan adalah Kec. Laren. Untuk mengurangi dampak kerugian yang terjadi maka penelitian ini merumuskan prioritas lokasi mitigasi bencana banjir di Kec. laren Kab. Lamongan. Dalam mencapai tujuan studi dilakukan identifikasi karakteristik ancaman bahaya hazard kerentanan vulnerability merumuskan zonasi risiko dan merumuskan prioritas lokasi mitigasi bencana banjir di wilayah studi Kec. Laren. Identifikasi karakteristik ancaman bahaya banjir dilakukan dengan analisis raster calculator dari variabel durasi genangan dan kedalaman genangan. Kemudian analisis scoring Likert scale untuk mendapatkan variabel-variabel kerentanan yang signifikan. Analisis ini juga digunakan dalam membobotkan variabel-variabel kerentanan. Analisis overlay weighted sum dilakukan dengan variabel-variabel kerentanan yang signifikan untuk mengidentifikasi karakteristik kerentanan bencana banjir. Zonasi risiko bencana banjir dianalisis dengan metode Raster Calculator memperhatikan fungsi risiko dipengaruhi oleh ancaman bahaya dan kerentanan. Kemudian hasil zonasi risiko tinggi dianalysis intersect untuk menunjukkan lokasi prioritas bagi upaya mitigasi. Karakteristik ancaman bahaya kerentanan dan zonasi risiko bencana banjir diklasifikasi ke dalam 5 kelashirarki. Risiko bencana banjir yang tertinggi berada pada Desa Centini dan Desa Tejoasri menyusul Desa Bulutigo Desa Mojoasem dan Desa Pesanggrahan. Sedangkan tingkat risiko yang paling rendah berada pada wilayah Desa Dateng Desa Karangtawar Desa Bulubrangsi Desa Gelap Desa Laren Desa Gampangsejati dan desa Godog.


ABSTRACT

The severest region that suffers from flood disaster of Bengawan Solo in Lamongan regency is Laren district. In order to reduce the impact of occurring loss determination of location priority of flood disaster mitigation based on risk zoning is needed. In order to reach the study aims this study performed characteristic identification of hazard and vulnerability risk zoning determination and location priority for mitigation determination. Characteristic identification of hazard analysis performed through raster calculator analysis of pool duration and depth. Further Likert scoring analysis performed due to obtain significant factors of vulnerability related to the study area. The analysis is performed also to determine weighting value of each significant vulnerability factors. Following overlay weighted sum analysis performed to indentify characteristic of vulnerability through weight value of significant factors obtained previously. Risk zoning of the flood disaster then determined through raster calculator regarding te function of risk equal with hazard times vulnerability.then after intersect analysis performed to determined the location priority of flood disaster mitigation in study area. Characteristics of hazard vulnerability and risk are classified into 5 classhierarchy. The highest flood disaster risk lies in village of Centini and Tejoasri then follows by Bulutigo Mojoasem Pesanggrahan. In the other hands the lowest flood disaster risk lies in village of Dateng Karangtawar Bulubrangsi Gelap Laren Gampangsejati and Godog.
