Perhitungan Analisis Proksimat Daun Desmodium rensonii

Penetapan kadar serat kasar

Diketahui :

Bobot sampel (x) = 1,0028     g

Bobot sampel + Crusible + Glasswool (oven 105 ^oC) (y) = 19,7448   g

Bobot sampel + Crusible + Glasswool (tanur 550 ^oC) (z) = 19,5487   g

Perhitungan :

Kadar SK = y - z  X 100 %

                        x

Kadar SK = 19,7448 – 19,5487 X 100 %

                             1,0028

                  = 27,111%

Penetapan kadar protein kasar

Diketahui :

Berat sampel (z) = 0,5053 g

Volume titrasi blanko (x) = 0,3 ml

Volume titrasi sampel (y) = 9,6 ml

Perhitungan :

Kadar protein kasar = (x – y) X 0,1 X 0,014 X 6,25 X 100%

                                                            z

Kadar protein kasar = (9,6 – 0,3) X 0,1 X 0,014 X 6,25) X 100%                                                                                                                    0,5053 

                                =  16,104%

Kadar protein kasar (dalam BK) =       100       X  kadar protein kasar

                                                              DMDW

                                                   =  ___100     X 16,104%

   92,464

                                                   = 17,416%

Kadar Ekstrak Eter

	I	II	III
Berat sampel (x)	0,5433	0,5227	0,5006
Berat kertas saring+sampel oven 105°C sebelum ekstraksi (y)	0,9525	0,9820	0,9120
Berat kertas saring+sampel oven 105°C setelah ekstraksi (z)	0,9410	0,9262	0,9029

Perhitungan :

Kadar ekstrak eter I              = y1 – z1  X 100 %

                                                      x1

                                                = 0,9525 – 0,9410 X 100 %

                                                              0,5433

                                                = 2,116%

Kadar ekstrak eter II             = y2 – z2  X 100 %

                                                       x2

                                                = 0,9820 – 0,9262 X 100 %

                                                              0,5227

                                                = 10,675%

Kadar ekstrak eter III            = y3 – z3  X 100 %

                                                      x3

                                                = 0,9120 – 0,9029 X 100 %

                                                             0,5006

                                                = 1,817%

Kadar ekstrak eter rata sampai rata = kadar ekstrak eter (I+II+III) X 100%

                                                                                        3

                                                            = 5,265%

Kadar Ekstrak Tanpa Nitrogen

ETN = 100 %  - ( kadar air+kadar abu+kadar serat kasar+kadar protein+kadar ekstrak eter)

         = 100 %  -  (7,536% + 9,275% + 27,111% + 17,416%+5,265)

         = 32,642%
