Abstract

Kalsium merupakan salah satu mineral penting yang terdapat pada susu segar. Kadar kalsium pada susu segar dapat dianalisa dengan menggunakan metode titrasi kelatometri. Tujuan penelitian ini adalah menentukan nilai ketidakpastian dalam analisis kadar kalsium pada susu segar secara titrasi kelatometri. Hasil identifikasi menunjukkan terdapat tujuh sumber ketidakpastian, yaitu buret yang digunakan untuk titrasi sampel, pipet mohr, recovery, ripitabilitas, linearitas, timbangan dan buret yang digunakan untuk titrasi larutan standar. Sumber ketidakpastian yang berkontribusi paling signifikan adalah recovery. Hasil perhitungan menunjukkan nilai ketidakpastian diperluas relatif kecil, yaitu 5.46 mg/100 mL, atau 3.76% dari kadar kalsium yang teranalisa.
