Abstract

Abstrak-Verifikasi metode pengujian Coliform dalam Air Mineral secara penyaringan membran yang mengacu pada SNI 3554 : 2015 Cara Uji Air Minum Dalam Kemasan telah dilakukan di Laboratorium Uji Baristand Industri Surabaya dan didapatkan nilai Presisi pada sampel dengan penambahan cemaran sebesar 10 koloni/ml sebesar 0.000, sampel dengan penambahan cemaran sebesar 100 koloni/ml sebesar 0.000, sampel dengan penambahan cemaran sebesar 500 koloni/ml sebesar 0.0699, sampel dengan penambahan cemaran sebesar 700 koloni/ml sebesar 0.0467, sampel dengan penambahan cemaran sebesar 1000 koloni/ml sebesar 0.000, Nilai Recovery pada sampel dengan penambahan cemaran sebesar 10 koloni/ml sebesar 85.03%, sampel dengan penambahan cemaran sebesar 100 koloni/ml sebesar 100.85%, sampel dengan penambahan cemaran sebesar 500 koloni/ml sebesar 99.22%, sampel dengan penambahan cemaran sebesar 700 koloni/ml sebesar 99.41%, sampel dengan penambahan cemaran sebesar 1000 koloni/ml sebesar 104.80%. Nilai linearitas sebesar 0.994. Hasil verifikasi tersebut telah memenuhi syarat keberterimaan sehingga metode tersebut dapat diterapkan di Labaoratorium Uji Baristand Industri Surabaya Kata kunci-air mineral; Verifikasi metode; Coliform Abstract-Verification of Coliform testing method in Mineral Water by membrane filter that refers to SNI 3554: 2015 Cara Uji Air Minum Dalam Kemasan has been carried out at the Testing Laboratory of Baristand Industri Surabaya and obtained a Precision value on the sample with the addition of contamination of 10 cfu / ml of 0,000, samples with addition of contamination by 100 cfu / ml by 0,000, samples with addition of contamination by 500 cfu / ml by 0.0699, samples with addition of contamination by 700 cfu / ml by 0.0467, samples with addition of contamination by 1000 cfu / ml by 0,000, Recovery Value in samples with the addition of contaminants by 10 cfu / ml by 85.03%, samples with the addition of contamination by 100 cfu / ml by 100.85%, samples with the addition of contamination by 500 cfu / the ml by 99.22%, samples with the addition of contamination by 700 cfu / ml by 99.41% , samples with the addition of contamination of 1000 cfu / ml by 104.80%. The value of linearity is 0.994. The verification results have met acceptance requirements so that the method can be applied in the Baristand Industri Surabaya Test Laboratory
