Abstract
Kegiatan penambangan material sirtu memberikan dampak positif dan negatif, dampak positifnya adalah bahan galian yang diambil dapat dimanfaatkan untuk memenuhi kebutuhan manusia dalam membangun infrastruktur dan sarana prasarana. Dampak negatif dari kegiatan pertambangan material sirtu adalah terjadinya perubahan tata guna lahan yang mempengaruhi potensi resapan air dan berdampak pada ketersediaan air tanah baik secara kuantitas maupun kualitas. Analisis kerentanan air tanah dilakukan sebagai upaya awal dalam menanggulangi penurunan potensi air tanah yang berpengaruh terhadap penurunan muka air tanah (groundwater level), debit air tanah, penurunan permukaan tanah (surface/land subsidence), dan kualitas air tanah. Penelitian ini dilakukan untuk mengetahui perbandingan hasil analisis kerentanan air tanah akibat kegiatan penambangan dengan menggunakan metode SVV dan DRASTIC. Kedua metode ini digunakan sebagai metode pembobotan dan penilaian. Metode DRASTIC dipengaruhi oleh beberapa faktor yaitu:, curah hujan, , media tanah, konduktivitas hidraulik, kedalaman muka air tanah, topografi (lereng), dan media akuifer, sedangkan metode SVV dipengaruhi oleh beberapa faktor yaitu: ketebalan dari zona tidak jenuh air, nilai recharge atau perkolasi, dan tipe material zona tidak jenuh air. Kedua metode ini diharapkan dapat mengetahui tingkat kerentanan air tanah erosi yang terjadi di daerah penelitian. Kata kunci: kerentanan, airtanah, metode, tambang, drastic, svv. ABSTRACT Sirtu material mining activities have positive and negative impacts, the positive impact is that the extracted mineral material can be utilized to meet human needs in building infrastructure and infrastructure. The negative impact of material mining activities is the occurrence of land-use changes that affect the potential for water catchment and have an impact on the availability of groundwater both in quantity and quality. Groundwater vulnerability analysis is carried out as an initial effort to overcome the reduction in groundwater potential that affects groundwater level, groundwater discharge, surface subsidence, and groundwater quality. This research was conducted to compare the results of groundwater vulnerability analysis due to mining activities using SVV and DRASTIC methods. Both of these methods are used as a method of weighting and valuation. The DRASTIC method is influenced by several factors, namely: rainfall, soil media, hydraulic conductivity, depth of groundwater level, topography (slope), unsaturated zone material, and aquifer media, while the SVV method is influenced by several factors namely: the thickness of unsaturated zone water, recharge or percolation value, and water unsaturated zone type material. Both of these methods are expected to be able to find out the level of erosion groundwater vulnerability that occurred in the study area Keywords : vulnerability, groundwater, methods, mining, drastic.
