Abstract
Air tanah merupakan salah satu sumber air yang banyak dimanfaatkan oleh manusia. Meningkatnya jumlah penduduk di wilayah Sub DAS Metro mengakibatkan terjadinya perubahan tata guna lahan, seperti pemukiman dan industri. Hal tersebut dapat menyebabkan air tanah menjadi lebih rentan terhadap pencemaran, sehingga berpengaruh pada kondisi kualitas air tanah. Dengan demikian, dilakukan analisis kerentanan air tanah untuk mengetahui tingkat kerentanan air tanah di wilayah Sub DAS Metro. Analisis kerentanan air tanah pada penelitian ini dilakukan dengan menggunakan metode modifikasi DRASTIC-LU. Parameter yang digunakan, yaitu Depth to Water Table (D), Net Recharge (R), Aquifer Media (A), Soil Media (S), Topography (T), Impact of Vadose Zone (I), Hydraulic Conductivity (C), dan Land Use (LU). Masing-masing parameter memiliki nilai bobot yang menunjukkan seberapa besar pengaruh terhadap kerentanan air tanah serta nilai peringkat yang dibagi ke dalam beberapa kelas. Sehingga, tingkat kerentanan air tanah dapat diketahui dengan menghitung nilai indeks. Berdasarkan hasil analisis, dapat diketahui bahwa nilai indeks kerentanan intrinsik dengan metode DRASTIC di wilayah Sub DAS Metro memiliki rentang nilai sebesar 98 – 114 yang termasuk ke dalam kategori tingkat kerentanan rendah. Sedangkan nilai indeks kerentanan intrinsik dan spesifik dengan metode DRASTIC-LU di wilayah Sub DAS Metro memiliki rentang nilai sebesar 133 – 159 yang termasuk ke dalam lima kategori, yaitu tingkat kerentanan sangat rendah (26,95%), tingkat kerentanan rendah (6,91%), tingkat kerentanan sedang (35,21%), tingkat kerentanan tinggi (27,33%), dan tingkat kerentanan sangat tinggi (3,59%).
English Abstract
Groundwater is one of the water sources that is widely utilized by humans. The increasing population in the Metro Subwatershed area has resulted in land use changes, such as settlements and industries. This can cause groundwater to become more vulnerable to pollution, thus affecting the condition of groundwater quality. Thus, a groundwater vulnerability analysis was conducted to determine the level of groundwater vulnerability in the Metro Subwatershed area. Groundwater vulnerability analysis in this study was conducted using the modified DRASTIC-LU method. The parameters used are Depth to Water Table (D), Net Recharge (R), Aquifer Media (A), Soil Media (S), Topography (T), Impact of Vadose Zone (I), Hydraulic Conductivity (C), and Land Use (LU). Each parameter has a weight value that indicates how much influence it has on groundwater vulnerability and a ranking value that is divided into several classes. Thus, the level of groundwater vulnerability can be determined by calculating the index value. Based on the results of the analysis, it can be seen that the value of the intrinsic vulnerability index using the DRASTIC method in the Metro Subwatershed area has a value range of 98 - 114 which is included in the low vulnerability level category. While the value of the intrinsic and specific vulnerability index with the DRASTIC-LU method in the Metro Subwatershed area has a value range of 133 - 159 which is included in five categories, namely very low vulnerability level (26.95%), low vulnerability level (6.91%), moderate vulnerability level (35.21%), high vulnerability level (27.33%), and very high vulnerability level (3.59%).
