Abstrak

Penelitian ini bertujuan untuk menilai kualitas air Sungai Pesouha dan mengetahui parameter kunci penyumbang pencemaran di Sungai Pesouha dengan menggunakan beberapa jenis analisis. Analisis nilai IP (Indeks Pencemaran) berkisar dari 0,617 hingga 2,47 yang menunjukkan status kualitas air Sungai Pesouha dari kondisi baik hingga pencemaran ringan. Selain itu, hasil analisis Indeks Kualitas Air (IKA-INA) berkisar dari 79,2 (cukup baik) hingga 90,93 (sangat baik). Analisis korelasi Cr6+ dan besi (Fe) dalam air sebesar 0,91; TSS dan Cr6+ sebesar 0,85; TSS dan Fe sebesar 0,86; TSS dan IP sebesar 0,68; Cr6+ dan IP sebesar 0,72; serta Fe dan IP sebesar 0,6. Analisis regresi dengan menggunakan kromium heksavalen (Cr6+) sebagai variabel bebas (X) dan nilai IP (Indeks Pencemaran) sebagai variabel terikat (Y), diperoleh nilai multiple R sebesar 0,722 yang menjelaskan bahwa korelasi antara X dengan Y termasuk dalam kategori kuat. Nilai Adjusted R2 mempunyai nilai sebesar 0,46 artinya X dapat menjelaskan Y, dalam hal ini parameter Cr6+ dapat menjelaskan Y atau Indeks Pencemaran sebesar 46% dan sisanya dipengaruhi oleh faktor lain. Persamaan regresi yang terbentuk adalah Y = (-0,099) + (0,12)X artinya jika nilai X = 0 maka nilai Y sebesar (-0,99) dengan pengaruh positif antar parameter.
