PEMANTAUAN KUALITAS LINGKUNGAN DI SEMENANJUNG MURIA PENENTUAN LOGAM BERAT DALAM CUPLIKAN PANTAI DENGAN AANI ANALISIS AKTIVASI NEUTRON INSTRUMENTAL

ABSTRAK

Telah dilakukan penelitian mengenai kualitas lingkungan di Semenanjung Muria Jepara Jawa Tengah ditinjau dari kandungan logam berat Hg Cd Cu As Cr dan Co dalam cuplikan air laut sedimen ikan dan alga coklat. Kandungan logam berat dianalisa dengan analisis aktivasi neutron instrumental AANI dimana cuplikan terlebih dulu ditembak dengan neutron sebelum dicacah menggunakan spektrometer gamma. Hasil analisis menunjukkan bahwa logam berat yang dapat terdeteksi adalah Hg Cd As Cr dan Co. Kadar logam Hg Cd dan Cr dalam cuplikan air laut serta logam Hg dalam cuplikan alga coklat telah melebihi baku mutu yang berlaku dan besarnya nilai faktor distribusi untuk sedimen 04793-34711610 dan faktor bioakumulasi untuk alga coklat 03871-885869 menunjukkan bahwa telah terjadi pencemaran di Semenanjung Muria Jepara Jawa Tengah. Uji Anova menunjukkan bahwa terdapat pengaruh lokasi pengambilan cuplikan terhadap kadar logam Hg Cd Cr dan Co dalam cuplikan air laut serta logam Cd Cr dan Co dalam cuplikan sedimen. Terdapat perbedaan kadar logam berat Cd Cr dan Co antar jenis ikan dan terdapat perbedaan kadar logam berat Hg Cd As Cr dan Co antar jenis alga coklat.


ABSTRACT

Research of environment quality in Muria Peninsula Jepara Central Java have been done observed from heavy metals content in sea water Sediment fish and brown algae. Presence of heavy metal can analized by instrumental neutron activation analysis INAA which a sample the first is bombarded with neutron before analyzed with gamma spectrometer. Result of analysis refer that presence of Hg Cd As Cr and Co in ocean sample. The heavy metal value of Hg Cd and Cr in sea water and Hg in brown algae have been more than threshold value and also high amount of distribution factor of sediment 04793- 34711610 and bioaccumulation factor of brown algae 03871- 885869 introducing which have been polluted in Muria Peninsula Jepara Central Java. Anova Method apear of a different for heavy metal value of Hg Cd Cr and Co each removal sample of sea water location. A different for heavy metal value of Cd Cr and Co each removal sample of sediment location. A different for heavy metal value of Cd Cr and Co each of fish species. A different for heavy metal value of Hg Cd As Cr and Co each of brown algae species.
