Abstract

Penelitian untuk menentukan profil pencemaran air sungai di muara Batang Arau kota Padang dari tinjauan fisis dan kimia berdasarkan nilai total padatan terlarut (TDS), konduktivitas listrik (EC), pH, dan kandungan logam berat Pb dan Fe yang telah dilakukan. Sampel air sungai diambil pada 10 lokasi di daerah muara dengan jarak antara lokasi adalah  200 m. Pengambilan sampel juga dilakukan di bagian tengah dan hulu sungai Batang Arau sebagai pembanding. TDS ditentukan dengan metode gravimetry, konduktivitas listrik diukur dengan conductivity meter, pH diukur dengan pH meter dan kosentrasi logam berat ditentukan menggunakan Atomic Absorption Spectroscopy (AAS). Nilai rata-rata TDS di daerah muara adalah 782,5 mg/l. Nilai ini sudah melebihi kadar kontaminasi untuk air minum yaitu 500 mg/l. Nilai rata-rata konduktivitas listrik di daerah muara adalah 172,5 µS/cm. Nilai ini jauh lebih tinggi dari pada nilai konduktivitas listrik air di perairan murni.  Nilai rata-rata pH di daerah muara 6,7, yang tergolong sebagai air netral. Kosentrasi logam berat Fe 0,105 mg/l dan Pb 0,005 mg/l. Kedua nilai ini masih berada di bawah ambang baku mutu air. Dari hasil yang didapatkan dapat disimpulkan bahwa kualitas air di muara Batang Arau masih dalam kondisi normal.
