Logam berat Cu dianalisa menggunakan AAS dan pigmen (klorofil dan fikobiliprotein) menggunakan spektrofotometri UV-Vis.Hasil yang didapat menunjukkan bahwa logam berat Cu dengan konsentrasi yang berbeda memberikan pengaruh yang sangat nyata (P<0,01) terhadap kandungan pigmen (klorofil dan fikobiliprotein), BCF dan pengaruh nyata (P<0,05) terhadap laju pertumbuhan P . cruentum. Semakin tinggi logam berat Cu membuat laju pertumbuhan, kandungan pigmen (klorofil dan fikobiliprotein), dan BCF pada P . cruentum semakin menurun.
