Abstract

Telah dilakukan penelitian untuk mengetahui karakteristik air lindi di Tempat Pembuangan Akhir (TPA) sampah Air Dingin Kota Padang. Pengambilan sampel air lindi dilakukan pada 6 titik lokasi, yaitu sebelum masuk kolam kendali, di kolam kendali, setelah keluar dari kolam kendali dan sungai. Karakteristik air lindi ditentukan dari beberapa parameter yaitu Total Dissolved Solid (TDS), konduktivitas listrik, pH, suhu, Chemical Oxygen Demand (COD), Biology Oxygen Demand (BOD) dan kandungan logam berat. Air lindi pada TPA memiliki nilai COD dan BOD serta kandungan logam berat Pb yang cukup tinggi dan telah melebihi nilai baku mutu pada beberapa titik tertentu (sebelum kolam, di dalam kolam dan setelah keluar dari kolam kendali). Untuk parameter suhu dan kandungan logam berat Cu dan Fe nilainya masih berada jauh di bawah baku mutu untuk semua titik sampel. Nilai parameter air lindi antara bak kendali berfluktuasi, dan ada yang justru jadi lebih tinggi setelah melewati proses pada kolam kendali seperti pada parameter konduktivitas listrik, TDS, pH dan kandungan logam berat Pb, Cu dan Fe. Dari hasil tersebut maka dapat diketahui bahwa fungsi kolam kendali air lindi yang ada di TPA Air Dingin masih kurang efektif.
