Abstract

Abstract. PT. X is a company engaged in the processing of zircon mining materials. In the processing process, it uses a water supply that only comes from groundwater. Groundwater sources at PT. X come from three drilled wells and each well is tested to determine the characteristics of the aquifer and the optimum discharge value. The research was conducted using the method pumping test, Pumping The test is divided into three stages, namely step drawdown test, constant rate test and recovery test. In the stages, the drawdown test and constant rate test groundwater level reduction value is obtained with a certain discharge, while the recovery test obtains the groundwater level recovery value. The results of the pumping test get the optimum discharge value from each well which is 10.6 lt/s for SB-01, 6.2 lt/s for SB-02, and 10.6 lt/s for SB-03, pumping with the optimum discharge into the safe category based on the regional regulation on groundwater damage criteria, West Java Provincial Regulation Number 1 of 2017 concerning the criteria for groundwater damage. Abstrak. PT. X merupakan perusahaan yang bergerak pada bidang pengolahan bahan tambang zircon. dalam proses pengolahannya menggunakan pasokan air yang hanya berasal dari airtanah. Sumber airtanah di PT. X berasal dari tiga sumur bor dan masing-masing sumur tersebut di uji untuk mengetahui bagaimana karakteristik akuifer dan nilai debit optimum. Penelitian dilakukan dengan metode pumping test, Pumping test terbagi menjadi tiga tahap yaitu step drawdown test, constant rate test dan recovery test. Pada tahapan drawdown test dan constant rate test mendapatkan nilai penurunan muka air tanah dengan debit tertentu, sedangkan recovery test mendapatkan nilai pemulihan muka air tanah. Hasil dari pumping test mendapatkan nilai debit optimum dari masingmasing sumur yaitu sebesar 10,6 lt/det untuk SB-01, 6,2 lt/det untuk SB- 02, dan 10,6 lt/det untuk SB-03, pemompaan dengan debit optimum masuk kedalam kategori aman berdasarkan perda kriteria kerusakan muka airtanah Perda Provinsi Jawa Barat nomor 1 tahun 2017 tentang kriteria kerusakan muka airtanah.
