Penentuan Kualitas Air Muara Sungai Batang Arau Melalui Pengujian Total Dissolved Solid (TDS), Total Suspended Solid (TSS), dan Kandungan Logam Berat

Penelitian ini bertujuan untuk menentukan konsentrasi logam berat, suhu, pH, konduktivitas listrik, total padatan terlarut (TDS) dan tersuspensi (TSS) pada sampel air muara Sungai Batang Arau. Nilai berat diukur menggunakan alat inductively coupled plasma (ICP), suhu termometer, pH meter, listrik konduktiviti TDS TSS ditentukan metode gravimerti. Dari hasil penelitian diperoleh nilai rata-rata sebesar 28,52 ?. 6,76. 176,43 µS/cm. 1040,5 ppm. Berdasarkan PP. No. 82 Tahun 2001 di batang Arau telah melebihi standar baku mutu kelas II yaitu 1000 mg/l. 204,9 ppm, juga 50 kosentrasi Cd, Cu, Hg yang ditetapkan 2001. didapatkan dapat disimpulkan bahwa kualitas terjadi pencemaran. This study aims to determine the concentration of heavy metals, temperature, electrical conductivity, totally dissolved solids and suspended in estuary samples River. The value metal was measured using an temperature a thermometer, conductivity were determined gravimerity method. From results study, average 28.52. is 6.76. 176.43 S/cm. 1040.5 Based on at River has exceeded class water quality standard, which 204.9 also PP standard. that equal values metals have standards set by obtained, it can be concluded been polluted.
