PENENTUAN INDEKS KERENTANAN AIRTANAH PESISIR JAWA DI WILAYAH SELAT SUNDA DENGAN MENGGUNAKAN METODE GALDIT
Abstract
Kerentanan airtanah pesisir merupakan salah satu isu yang sangat penting dalam perkembangan pembangunan saat ini. Antisipasi dan upaya mengurangi dampak negatif kualitas airtanah wilayah pesisir akibat faktor antropogenik dan perubahan iklim, memerlukan upaya penentuan indikasi daerah yang memiliki kerentanan tinggi. Upaya pembobotan diperlukan berdasarkan faktor-faktor yang paling penting dalam memahami kerentanan airtanah wilayah pesisir. Metode GALDIT merupakan salahsatu sistem peringkat numerik untuk menilainya. Tiga komponen penting dari sistem ini adalah kriteria bobot, rentang data dan peringkatnya. Fokus dari penelitian ini adalah pada penerapan dan metode GALDIT untuk mengakses kerentanan airtanah pesisir di wilayah Pulau Jawa sepanjang Selat Sunda. Kesimpulannya, metode ini perlu diintegrasikan dengan faktor kerentanan lokal dan dibandingkan dengan metode lainnya agar dapat diaplikasikan dengan lebih akurat.
Groundwater coastal vulnerability is one of the most important issues in the human development today. Anticipation to mitigate negative impacts of groundwater coastal quality due to climate change impacts and anthropogenic activities, required to indicate the zonation with high vulnerability index. The GALDIT method is a one of numerical rating system for assessing the susceptibility of groundwater coastal vulnerability. Three important parts of this system were weighting criteria, range of data and ratings. The focus of this research is to applied GALDIT method to access groundwater coastal vulnerability in Jawa Island along the Sunda Strait. In conclusion, this method needs to be integrated with local vulnerability factors and compared with other methods to be applied more accurately.
