Aplikasi Persamaan Regresi Linier untuk Memprediksi Kebutuhan Kapur Tohor dan Biaya Netralisasi Air Asam Tambang
Application of Linear Regression Equation to Predict Quicklime Needs and Acid Mine Water Neutralization Costs
Abstract
Abstract
Acid mine drainage has the potential to pollute water bodies. One method of acid mine drainage treatment is neutralization using quicklime. This study aims to plan the dose of quicklime and estimate the cost of neutralizing acid mine drainage using a linear regression equation. Acid mine drainage samples were obtained from PT Bukit Asam. Neutralization experiments were carried out on a laboratory scale using variable doses of quicklime: 0.0759, 0.0971, 0.1460, 0.2965, and 0.3877 g/L. The results showed that the acid mine drainage samples contained parameters of pH 3.6, TSS 87 mg/L, Fe 1.1239 mg/L, and Mn 3.8333 mg/L. Neutralization of acid mine drainage using quicklime at a dose of 0.1460-0.2965 g/L was able to increase pH by 33-153% and decrease TSS by 2-94%, Fe by 24-87%, and Mn by 14-43%. The linear regression equation obtained is y = 13.707x + 4.103, where x is the dose of quicklime (g/L) and y is pH. Calculations using the linear regression equation produce a dose requirement of quicklime of 0.1383–0.3572 g/L to produce acid mine water with a pH of 6-9. Meanwhile, processing acid mine water with a discharge of 86,400 m³/day requires quicklime of 11,949-30,862.08 kg/day and costs of Rp10,156,650.00–26,232,700.00/day.

Abstrak
Air asam tambang berpotensi mencemari badan air. Salah satu metode pengolahan air asam tambang adalah netralisasi menggunakan kapur tohor. Penelitian ini bertujuan untuk merencanakan dosis kapur tohor dan memperkirakan biaya netralisasi air asam tambang menggunakan persamaan regresi linier. Sampel air asam tambang diperoleh dari PT Bukit Asam. Percobaan netralisasi dilakukan dalam skala laboratorium menggunakan variabel dosis kapur tahor : 0,0759; 0,0971; 0,1460; 0,2965; 0,3877 g/L. Hasil penelitian menunjukkan bahwa sampel air asam tambang mengandung parameter pH 3,6; TSS 87 mg/L; Fe 1,1239 mg/L; Mn 3,8333 mg/L. Netralisasi air asam tambang menggunakan kapur tohor dosis 0,1460-0,2965 g/L mampu menaikkan pH 33-153%; menurunkan : TSS 2-94%, Fe 24-87%, dan Mn 14-43%. Persamaan regresi linear yang diperoleh adalah y = 13,707x + 4,103; dengan x adalah dosis kapur tohor (g/L) dan y adalah pH. Perhitungan menggunakan persamaan regresi linear menghasilkan kebutuhan dosis kapur tohor sebesar 0,1383 – 0,3572 g/L untuk menghasilkan air asam tambang pH 6-9. Sedangkan untuk mengolah air asam tambang dengan debit 86.400 m3/hari membutuhkan kapur tohor sebesar 11.949-30.862,08 kg/hari dan biaya Rp 10.156.650,00 – 26.232.700,00/hari.
