PENGUKURAN KADAR TOTAL DISSOLVE SOLID (TDS) DAN TOTAL SUSPENDED SOLID (TSS) PADA AIR LAUT DI PERAIRAN TELUK LAMPUNG
ABSTRAK INDONESIA Penelitian tentang pengukuran kadar Total Dissolve Solid (TDS) dan Total Suspended Solid (TSS) pada air laut telah dilakukan di sekitar perairan Teluk Lampung. Konsentrasi Total Dissolve Solid (TDS) dan Total Suspended Solid (TSS) ditentukan menggunakan metode gravimetri dengan parameter validasi metode yaitu presisi. Hasil penelitian menunjukkan konsentrasi Total Dissolve Solid (TDS) berada pada rentang 27.868 ppm sampai dengan 36.642 ppm. Konsentrasi Total Suspended Solid (TSS) berada pada rentang 64 ppm sampai dengan 118 ppm, berdasarkan Keputusan Menteri Lingkungan Hidup Tahun 2004, baku mutu konsentrasi Total Suspended Solid (TSS) yaitu pada rentang 23,77-80,07 ppm, hasil analisis menunjukan kadar Total Suspended Solid (TSS) telah melebihi baku mutu. Validasi metode pada penentuan kadar Total Suspended Solid (TSS) pada air laut menunjukan presisi dengan nilai relatif standar deviasi (RSD) berada pada rentang1,4- 13 %. Sedangkan validasi metode pada penentuan kadar Total Dissolve Solid (TDS) pada air laut menunjukkan presisi dengan nilai relatif standar deviasi (RSD) berada pada rentang 2,3–24 %.

ABSTRAK INGGRIS The research of the concentration measurement Total Dissolve Solid (TDS) and Total Suspended Solid (TSS) sea have already done in Teluk Lampung waters. The concentration of Total Dissolve Solid (TDS) and Total Suspended Solid (TSS) is decided by using gravimetric method with parameter validity method, precicition. The result of this research shows that the concentration of Total Dissolve Solid (TDS) the ranges 27.868 ppm to 36.642 ppm while the concentration of Total Suspended Solid (TSS) the ranges 64 ppm to 118 ppm. Based on Decree of the Environment Minister 2004, the standart quality of concentration Total Suspended Solid (TSS) the ranges 23,77 ppm to 80,07 ppm. The result shows that the degree exceed standard quality. Validity method in determining degree of Total Suspended Solid (TSS) of the sea water shows that precicition with Relative Standard Deviation (RSD) rangesfrom 1,4% to 13% while validity method in determining degreee of Total Dissolve Solid (TDS) of the sea water shows that preciciton with Relative Standard Deviation (RSD) ranges from 2,3% to 24%.
