  1. PenentuanKadar GlukosadalamUrine secaraTitrimetri Oleh: Kelompok 3 1. SitiNursiami (43014100xx) 2. SitiMunawaroh (4301410008) 3. HeliviaElvandari (4301410013) UniversitasNegeri Semarang 2012

  2. Memahamiprosedurdanprinsipdasaranalisiskadarglukosadalam urine Tujuan Terampil melakukan analisis kadar glukosa dalam urine menggunakan metode titrimetri

  3. Harganormal glukosadalam urine per24 jam sebesar 0,5 sampai 1,0 gram LatarBelakang • Banyakterkandungdalmgulatebu, buah, madu, urine dandarah Glukosa • Gula yang dapatmereduksilarutanfehling, tollens • Kadar glukosadalam urine dapatdicaridenganmenggunakanmetodetitrimetri

  4. 10 ml CuSO4 +10 ml larutansignette+5 ml kaliumferrosianida 5% Cara kerja Larutan(dititrasi) Glukosa 5% Urine + glukosa (2:1) Zatkompleks Zatkompleks

  5. Data pengamatan

  6. Analisis data Hasiltitrasiglukosa0.5% = 3.93mL Hasiltitrasicampuran urine glukosa0.5% = 9.0mL Beratglukosa0.5% = 0.5 gr/100 mL x 3.93 mL = 0.01967 gr Beratglukosadalamcampuran urine glukosa (2:1) Volume glukosa0.5% = (1/3) x 9.0 mL x (0.5 gr/100 mL) =0.015 gr Volume urine saja = 9.0 mL – ((1/3) x 9.0 mL) = 6.0 mL Jadikadarglukosadalam urine sebagaipenitir = = (beratglukosa – beratglukosadalamcampuran)x 100%/volume urine saja = (0.01967 – 0.015)/6.0 x 100% = 0.067%
