CARA PERHITUNGAN 1. Residu yang ada pada berat kertas saring = (berat kertas saring +residu)-berat kertas saring C



=B



-



A



2. (berat kertas saring +residu) setelah pengeringan= (berat kurs+kertas saring+ residu) – (berat kurs) F



=



E



-D



3. Berat residu setelah pengabuan = (berat kertas saring +residu) setelah pengeringan – berat kertas saring yang diabukan H



= F



4. Blanko = Kertas saring awal – berat kertas saring yang diabukan I



=A



-G



5. IDF dan SDF = (C-H-I) /(W)*100 Keterangan :W = berat awal
