| dc.description.abstract | Mengacu pada SNI ISO/IEC 17025:2017 laboratorium harus memiliki prosedur untuk memantau keabsahan hasil pengujian secara sistematik dan seluruh personel yang terlibat dalam kegiatan laboratorium harus memiliki kompetensi. Penelitian ini bertujuan untuk memverifikasi kinerja personel dalam penentuan total asam tertitrasi dengan mengevaluasi tingkat presisi hasil pengujian yang diperoleh dari masing-masing analis. Hasil penelitian menunjukkan bahwa seluruh sampel bersifat homogen, namun lama penyimpanan memengaruhi hasil total asam pada saus sambal dan madu, sedangkan minuman teh rasa berry tetap stabil. Evaluasi presisi menunjukkan adanya analis yang belum memenuhi kriteria presisi serta perbedaan signifikan antaranalis pada saus sambal dan madu, tetapi tidak pada minuman teh rasa berry. | |
| dc.description.abstract | According to SNI ISO/IEC 17025:2017, laboratories are required to establish procedures for systematically monitoring the validity of test results, and all personnel involved in laboratory activities must demonstrate competence. This study aimed to verify personnel performance in the determination of total titratable acidity (TTA) by evaluating the precision of test results obtained from each analyst. The results showed that all samples were homogeneous however storage duration affected the total titratable acidity of chili sauce and honey, whereas the berry-flavored tea beverage remained stable. The precision evaluation indicated that some analysts did not meet the required precision criteria, and significant differences among analysts were observed for chili sauce and honey, but not for the berry-flavored tea beverage. | |
