```									 Perhitungan pH Tanah Setelah Inkubasi

1.   Faktor koreksi (FK)         =

=

Jumlah Kuadrat total (JK total)     =     –
= (5.002 + 4.962 +.............+ 3.692) – 729.28
= 733.48 – 729.28
=4.20
= (14.992 + 15.062 + .......... + 12.982)/3 – 729.28
=
= 2.27
Jumlah kuadrat mi (JK mi)                   =
= (56.712+52.662+52.662)/12 – 729.28
=
= 244.29
Jumlah Kuadrat db (JK db)                   =

= (41.542+41.942+39.672+38.882)/12- 729.28

=

= -181.79
=0.18
Jumlah Kuadran Interaksi (JK.Int)           = JKP-JK(mi)-JK(db)
= 2.27-244.29-0.18
= 0.242

Jumlah Kuadran error (JK error)             = JK total-JKP

= 4.20-2.27
= 1.93
2.   Penentuan derajat bebas
db perlakuan            = mi.db-1

= 3.4-1 = 12-1 = 11

db mi                   = mi-1 = 3-1 = 2

db Db                   = db-1 = 4-1 = 3

db Interaksi (midb)     = (mi-1) (db-1)

= (3-1) (4-1)

= 2x3 =6

db galat                = mi.db (r-1)

= 9 (3-1)

= 9x2

= 18

db total                = (r.mi.db)-1

= (3x3x4)-1

= 36-1

= 35

Kuadrat tengah faktor masa inkubasi (KTmi)    =
Kuadrat tengah factor dosis bokashi (KTdb)    =

Kuadrat tengah interaksi (KT Int)        =

4.   Koefisien keberagaman (KK)

KK =

=          = 0.282

5.   F hitung (F.hit)

F. Hitung perlakuan (F. hit P)           =

F. hitung factor Masa Inkubasi (F.hit mi) =

F. Hitung factor dosis bokashi (F.hit db) =

F. Hitung interaksi (F. hit.Int)         =

Setelah didapat F. Hitung, maka hasilnya dibandingkan dengan F table taraf 5% sehingga
