KROMIUM (Cr) PADA SEDIMEN DAN PLANKTON PESISIR GUNUNG
ANAK KRAKATAU SECARA SPEKTROFOTOMETRI SERAPAN ATOM
(SSA)
%X Telah dilakukan penentuan kandungan logam berat Tembaga (Cu), Besi (Fe), dan
Kromium (Cr) pada Sedimen dan Plankton Pesisir Gunung Anak Krakatau Secara
Spektrofotmetri Serapan Atom (SSA). Penelitian ini dilakukan untuk mengetahui
pencemaran logam berat diperairan Pesisir Gunung Anak Krakatau. Sampel
diambil dari 2 titik berbeda. Preparasi sampel dilakukan dengan cara destruksi
basah dan dianalisis menggunakan Spektrofotometri Serapan Atom. Hasil analisis
pada sedimen menunjukkan bahwa kadar logam Cu, Fe, dan Cr pada masingmasing
lokasi sebesar (79,224 0,134 ppm; 79,383 0,063 ppm), (152,875
0,031 ppm; 152,837 0,044 ppm), (11,85 ppm; 11,87 0,791 ppm).
Konsentrasi logam Cu dan Fe berada di atas ambang baku mutu dan logam Cr
berada di bawah ambang baku mutu yang ditetapkan National Sediment Quality
Survey USEPA (2004). Hasil Analisis kandungan logam Cu dan Cr pada air
berturut-turut 0,061 ppm dan 0,018 ppm berada diatas baku mutu sedangkan
logam Fe sebesar 1,187 ppm berada di bawah ambang baku mutu yang sudah
ditetapkan oleh Keputusan Kementrian Negara Lingkungan Hidup No. 51 tahun
2004. Hasil analisis kandungan logam Cu dan Cr pada plankton 0,097 ppm dan
0,101 ppm berada diatas baku mutu sedangkan logam Fe sebesar 0,141 ppm
berada dibawah baku mutu standar.

Determination of the content of heavy metals Copper (Cu), Iron (Fe), and
Chromium (Cr) in Sediments and Coastal Plankton Mount of Anak Krakatau by
Atomic Absorption Spectrophotometry (AAS). This research was conducted to
determine heavy metal pollution in the coastal waters of Mount Anak Krakatau.
Samples were taken from 2 different points. Sample preparation was carried out
by wet destruction and analyzed using Atomic Absorption Spectrophotometry.
The results of analysis on the sediments showed that the levels of Cu, Fe, and Cr
metals at each location were (79.224 ? 0.134 ppm; 79.383 ? 0.063 ppm), (152.875
? 0.031 ppm; 152.837 ? 0.044 ppm), (11.85 ? 0.299 ppm; 11.87 ? 0.791 ppm).
The concentrations of Cu and Fe are above the quality standards and Cr is below
the quality standards set by the USEPA National Sediment Quality Survey (2004).
The analysis results for the content of Cu and Cr metals in water were 0.061 ppm
and 0.018 ppm respectively above the quality standard while Fe metal of 1.187
ppm was below the quality standard threshold stipulated by Decree of the State
Ministry of Environment No. 51 of 2004. The results of analysis of the content of
Cu and Cr metals in plankton 0.097 ppm and 0.101 ppm were above the quality
standard while Fe metal of 0.141 ppm was below the quality standard.
