Abstract

'retail di lakukan Evaluasi KinedaMetoda Analisis Pengaktifan Neutron dengan tujuan untuk validasi data haSil analisis pada. penenhian kadar unsur kelumit dalam air sedimen. Evaluasi moliputi uji kestabilan alat„ cacah latai Figure of. .Merit (POW Critical Level (Lc),iDetection Limit (LD), Determination Limit (La) can uji kiialitas has i . Hasil evaluasi memperlihatkan bahwa alat dalam keadaan stabil dengan cacah latar berkisar 0,0037 hingg4 0,1806 cps dan Kemampuan alat ukur atau Figure of Merit (,rq.)21.4) bodcisar 0,0045 hingga 0,1732 cletik. Hasil analisis yang diperoleh diatas Criticca Levie (LO, dengan sebesar 0,07 hingga 16,42 ppb.

Uji klial if hasil men:tpunyli angka p:myimpaugan sebesar 15,17% hingga Iebih bestir 50% dan hasil analisis sebesar 0,01% hingga 99,00%. Evaluation of the Neutron Activation Analysis (1VAA) methods performance has been done. The objective of this study is to validate the data from these analysis on the determination of the trace element concentration in the waters and sediments. This evaluation covering test of devices stability, background counting, Figure of Merit (F0.4, Critical Level (Lc), Detection Limit (LD), Determination Limit (Lc) and test of quality result. Result show that device in stabil condition have background counting about 0,0037 to 0,1806 cps, Figure of Merit (FOli4) about to 0,0045 to 0,1732 sekon. The data result analysis above Critical Level (La), In Lc about 0,07 to 16,42 ppb. Detection Limit (LD) about 0,14 to 32,93 ppb in significant 95% expect Fig obtained LD 1,26 ppb. Determination Limit (LQ) about 0,44 to 100,10 ppb. Test of quality result show that of standardized difference about 15,17% to above 50% and Precision result analysis about
