Penelitian ini menggunakan metode Multicriteria Evaluation (MCE) bagi pengambil keputusan dalam menentukan bobot dan metode yang sesuai serta menggunakan Weighted Linear Combination (WLC) dalam menganalisis daerah rawan banjir. Hasil penelitian menunjukkan bahwa Kecamatan Teluk Ambon memiliki wilayah terluas pada setiap kelas kerawanan banjir di Kota Ambon dibandingkan dengan kecamatan lainnya, hal ini dikarenakan kecamatan tersebut merupakan yang terbesar di Kota Ambon. Sedangkan luas lahan pemukiman yang tersebar pada kawasan kelas kerawanan tinggi memiliki persentase luas paling besar yaitu 2.222,06 ha. Sebaran permukiman pada kelas kerawanan sedang seluas 2.214,67 ha yang tersebar di lima kecamatan di Kota Ambon. Sedangkan kawasan terbangun yang berada pada tingkat kerawanan sedang adalah 0,39 ha.

Hasil dari penelitian ini menunjukan terjadinya pembentukan awan-awan konvektif di atas Pulau Madura bagian Timur yang bergerak menuju wilayah Bangkalan di Pulau Madura bagian Barat dengan suhu puncak awan mencapai -58 oC. Pada tanggal 17 Oktober 2021, wilayah Madura berada dalam periode transisi, terlihat dari angin dominannya masih dipengaruhi oleh monsun Australia dan mulai menguatnya monsun Asia. Hal ini memicu terbentuknya shearline di wilayah Madura dan sekitarnya. Selain itu, suhu permukaan laut di sekitar wilayah Madura cukup panas, sehingga meningkatkan penguapan dan memicu labilitas udara yang kuat. Kondisi ini memicu terbentuknya awan konvektif yang menyebabkan terjadinya angin kencang di wilayah tersebut.Strong winds above 25 knots can cause damage, for example, infrastructure and fallen trees. This study aims to determine the dynamics of the atmosphere during strong winds in the Bangkalan, Madura October 17, 2021. The method used was a descriptive analysis of weather variables and satellite imagery of Himawari-8 using the Sataid application. The results indicate the formation of convective clouds over the eastern part of Madura that moves towards the Bangkalan area on the western part of Madura, cloud peak temperatures reaching -58oC. On October 17, 2021, the Madura region is in a transition period, as can be seen from the dominant winds that are still influenced by the Australian monsoon also the Asian monsoon is starting to strengthen. The monsoon triggers the formation of a shearline in Madura and surrounding areas. Furthermore, the sea surface temperature around the Madura area is quite hot, thereby increasing evaporation and triggering strong air lability. This condition triggers the formation of convective clouds that cause strong winds.","PeriodicalId":204573,"journal":{"name":"Jurnal Geografi : Media Informasi Pengembangan dan Profesi Kegeografian","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132078658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
