LANDSLIDE DISASTER RISK ZONING IN THE AREA OF MOUNT BROMO SLOPE-PASURUAN

PERMANA, SANDY RIZA  ( 3606100039 )




ABSTRAK

Kawasan yang berada di lereng Gunung Bromo Kabupaten Pasuruan memiliki potensi timbulnya sejumlah bencana tanah longsor beserta dampak negatif yang ditimbulkannya mengindikasikan kurangnya mitigasi bencana berupa kewaspadaan dan kesiapan dalam menghadapi ancaman bahaya. Karena kondisi daerah yang berpotensi dan rawan terkena dampak maka perlu untuk mengkaji tingkat risiko bencana tanah longsor sebagai upaya untuk memposisikan masyarakat dan daerah yang bersangkutan pada tingkatan risiko yang berbeda. Penelitian ini bertujuan untuk merumuskan penentuan zonasi risiko bencana tanah longsor di lereng Gunung Bromo Pasuruan. Tahapan analisis yang dilakukan yang pertama yaitu mengidentifikasi faktor-faktor pemicu terjadinya bahaya longsor dan faktor-faktor serta indicator yang secara signifikan berpengaruh terhadap kerentanan dengan menggunakan analisis delphie kemudian dilakukan pembobotan dengan analisis AHP kedua mengidentifikasi karakteristik dan zonasi bahaya hazard tanah longsor dengan menggunakan analisis overlay ketiga menentukan zonasi kerentanan vulnerability bencana tanah longsor dengan menggunakan analisa overlay weight sum dan yang terakhir menentukan zonasi risiko risk dari bencana tanah longsor dengan menggunakan analisis map algebra overlay sebagai upaya mitigasi bencana. Dari hasil analisis karakteristik bahaya hazard kawasan longsor dan kerentanan vulnerability bencana diketahui zonasi risikorisk bencana tanah longsor yang diketahui dari variabel ancaman hazard dan kerentanan vulnerebility. Berdasarkan hasil kajian pustaka dan analisis map algebra overlay didapatkan lima kategori yaitu zona risiko sangat tinggi Area terdampak zona risiko tinggi zona risiko sedang zona risiko rendah dan zona risiko sangat rendah untuk masing-masing kelurahandesa di Kawasan Rawan Longsor.


ABSTRACT

The area which located on the slopes of Mount Bromo Pasuruan has the potential emergence of a number of landslides and the resulting negative impact indicating a lack of awareness of disaster mitigation and preparedness in facing the threat of danger. Because local conditions are potentially affected and vulnerable it is necessary to assess the level of landslide disaster risk as an attempt to position the respective communities and regions in different levels of risk. This study aims to formulate the landslide determination of hazard risk zoning on the slopes of Mount Bromo Pasuruan. First to identify the factors that trigger the occurrence of landslide hazard and the factors and indicators that significantly affect the vulnerability by using analysis Delphie then be weighted by AHP analysis second both identifying and zoning characteristics danger hazard by a landslide using overlay analysis the thirds decide zoning vulnerability vulnerability landslides using overlay analysis of weight-sum and the last determining the risk zone risk of landslides using algebra map overlay analysis as disaster mitigation efforts. From the results of hazard characteristics analysis hazard area of landslides and susceptibility vulnerability zoning known by disaster risks risk of known landslides of variable threat hazard and vulnerability vulnerebility. Based on literature review and results of algebra map overlay analysis there are five categories very high risk zone area affected high risk zone the zone of moderate risk low risk zone and the very low risk zone for each of the villages in Avalanche Prone Regions
