Abstract
Air tanah merupakan sumber daya yang vital bagi kehidupan, terutama sebagai sumber utama pemenuhan kebutuhan air bersih bagi masyarakat. Namun, peningkatan aktivitas penduduk, perkembangan permukiman, serta aktivitas industri di berbagai wilayah telah menyebabkan potensi pencemaran air tanah semakin meningkat. Kecamatan Baleendah, sebagai salah satu wilayah dengan pertumbuhan penduduk yang pesat dan beragamnya aktivitas manusia, menghadapi risiko penurunan kualitas air tanah akibat pencemaran. Oleh karena itu, penilaian kerentanan pencemaran air tanah menjadi langkah penting untuk mengidentifikasi area-area yang berpotensi tinggi mengalami pencemaran. Penelitian ini bertujuan untuk menganalisis kerentanan pencemaran air tanah potensial dan aktual serta mencari hubungan dan pengaruh pada setiap pemodelan dan faktor penyebabnya di Kecamatan Baleendah menggunakan metode DRASTIC dan pemanfaatan Sistem Informasi Geografis (SIG). Analisis ini mempertimbangkan tujuh parameter utama, yaitu kedalaman muka air tanah, imbuhan air tanah, litologi akuifer, tekstur tanah, topografi, zona tidak jenuh, dan konduktivitas hidraulik. Hasil penelitian menunjukkan bahwa kerentanan pencemaran air tanah potensial memiliki nilai berkisar antara 41 hingga 157, dengan empat kelas kerentanan: rendah (1195,937 ha), sedang (325,84 ha), tinggi (984,494 ha), dan sangat tinggi (1565,373 ha). Distribusi kerentanan potensial dipengaruhi oleh kedalaman muka air tanah, jenis zona tidak jenuh, dan konduktivitas hidraulik sebagai parameter dominan. Sementara itu, kerentanan aktual memiliki nilai antara 51 hingga 197, dengan distribusi kelas kerentanan rendah (1038,816 ha), sedang (958,7918 ha), tinggi (879,5839 ha), dan sangat tinggi (1194,478 ha). Analisis korelasi menggunakan metode Spearman menunjukkan hubungan signifikan antara kerentanan potensial DRASTIC dan modifikasi dengan nilai signifikansi regresi sebesar 0,001. Korelasi ini mengindikasikan bahwa perubahan penggunaan lahan berimplikasi pada peningkatan kerentanan aktual terhadap pencemaran. Selain itu, penelitian ini menunjukkan bahwa aktivitas manusia, seperti urbanisasi dan alih fungsi lahan, berperan besar dalam meningkatkan kerentanan pencemaran air tanah. Groundwater is a vital resource for life, especially as the main source that provides clean water for the community. However, increasing population activity, organizational development, and industrial activities in various regions have caused the potential for air pollution to increase. Baleendah District, as one of the areas with rapid population growth and various human activities, faces the risk of declining groundwater quality due to pollution. Therefore, assessing the vulnerability of groundwater pollution is an important step to identify areas with high potential for pollution. This study aims to analyze air pollution vulnerability, potential and actual, and to find the relationship and influence on each modeling and causal factors in Baleendah District using the DRASTIC method and the use of Geographic Information Systems (GIS). This analysis considers seven main parameters, namely groundwater depth, groundwater recharge, aquifer lithology, soil texture, topography, unsaturated zones, and hydraulic conductivity. The results showed that the potential soil air pollution vulnerability had values ranging from 41 to 157, with four vulnerability classes: low (1195.937 ha), moderate (325.84 ha), high (984.494 ha), and very high (1565.84 ha). 373 ha). The distribution of potential vulnerability is influenced by the depth of the groundwater table, the type of unsaturated zone, and hydraulic conductivity as dominant parameters. Meanwhile, the actual vulnerability had values ranging from 51 to 197, with the distribution of low (1038.816 ha), moderate (958.7918 ha), high (879.5839 ha), and very high (1194.478 ha) vulnerability classes. Correlation analysis using the Spearman method showed a significant relationship between the potential DRASTIC vulnerability and modification with a regression significance value of 0.001. This correlation indicates that changes in land use have implications for increasing actual vulnerability to pollution. In addition, this study shows that human activities, such as urbanization and land conversion, play a major role in increasing the potential for soil air pollution.
