| dc.description.abstract | Keberadaan logam timbal (Pb) dalam kecap perlu dilakukan pengawasan mengingat akibat bahayanya logam tersebut jika masuk ke dalam tubuh dengan jumlah berlebih. Menurut SNI 7387:2009 batas kadar timbal yang diperbolehkan dalam kecap adalah sebesar 1,0 mg/kg. Penentuan logam timbal dilakukan menggunakan metode spektrofotometri serapan atom (SSA) melalui proses preparasi metode destruksi basah. Metode destruksi basah dilakukan dengan menggunakan HNO3 65% dan HClO4 60% yang mengacu pada APHA 2023. Sampel yang telah didestruksi kemudian diukur menggunakan spektrofotometer serapan atom nyala Perkin Elmer 300 sebanyak 7 kali. Hasil penelitian menunjukkan nilai Linearitas sebesar 0,999, nilai LD 0,0148 mg/L, nilai LK 0,0447 mg/L, nilai repeatabilitas 2,8328%, nilai %perolehan kembali sebesar 100,35%. Analisis statistika pada uji ketahanan menunjukkan hasil f-hitung < f-tabel dan analisis statistika pada uji ketangguhan menunjukkan hasil t-hitung < t-tabel. Nilai seluruh parameter uji yang didapat ini telah memenuhi persyaratan yang ditentukan. | |
| dc.description.abstract | The Presence of lead (Pb) in soy sauce needs to be monitored due to the harmful effects of this metal when ingested in excessive amounts. According to SNI 7387:2009, the permissible lead content in soy sauce is 1,0 mg/kg. The determination of lead metal is carried out using the atomic absorption spectrophotometry (AAS) method through a wet digestion preparation process. The wet digestion method is performed using 65% HNO3 dan 60% HClO4, referring to APHA 2023. The digested samples are then measured using a Perkin Elmer 300 flame atomic absorption spectrophotometer seven times. The result of the study shows a linearity value of 0.999, LOD of 0.0148 mg/L, LOQ of 0.0447 mg/L, repeatability value of 2.8328%, and a recovery rate of 100.35%. Statistical analysis of the robustness test shows f-calculated < f-table and statistical analysis of the ruggedness shows t-calculated < t-table. The values of all the obtained test parameters meet the specified requirements. | |
