Abstract

Telah dilakukan penelitian untuk menentukan profil pencemaran sungai Batang Arau daerah Lubuk Begalung Kota Padang. Pengambilan sampel dilakukan pada bulan September 2015 pada 8 titik dengan jarak antara titik adalah 500 meter pada dua waktu yang berbeda yaitu pagi dan sore hari. Ada 4parameter yang diukur yaitu kandungan logam berat Cu dan Zn, konduktivitas listrik, pH dan temperatur. Hasil penelitian menunjukkan bahwa rata-rata kandungan logam berat Cu pada pagi hari adalah 0,034 mg/l dan pada sore hari adalah 0,039 mg/l, rata-rata kandungan logam berat Zn pada pagi hari adalah 0,055 mg/l dan pada sore hari adalah 0,062 mg/l. Rata-rata konduktivitas listrik air sungai pada pagi hari adalah 235,5 μS/cm dan pada sore hari adalah 468 μS/cm. Rata–rata pH air sungai pada pagi hari adalah 7,03 dan pada sore hari 7,08. Temperatur rata-rata air sungai pada pagi hari adalah 29,3°C dan pada sore hari adalah 30,05°C. Jadi ditinjau dari kandungan logam berat Cu dan Zn, konduktivitas listrik dan temperatur, maka sungai Batang Arau daerah Lubuk Begalung kota Padang dapat dikatakan sudah tercemar, karena parameter tersebut berada di atas nilai standar baku mutu air sungai menurut Peraturan Pemerintah Republik Indonesia Nomor 82 Tahun 2001.

Kata kunci: konduktivitas listrik, logam berat, pH, temperatur
