c. koefisien Sorensen (quantitative data)

CN =2jN

(aN + bN)

=2 (63)

(181 + 63)

CN = 0,52

d. koefisien Morisita-Horn (quantitative data)

CMH =2 Σ (ani x bni)

(da + db) aN x bN

Σ (ani x bni) = [(21 x 0) + (45 x 29) + (4 x 0) + (2 x 0) + (9 x 32) + (100 x 2)]= (1305 + 288 + 200)= 1793

2 Σ (ani x bni)= 3586

da = Σ ani²

aN²

=Σ (21² + 45² + 4² + 2² + 9² + 100²)

(181)²

=(441 + 2025 + 16 + 4 + 81 + 10000)

(181)²

db = 0,47

Maka,

CMH =2 (1793)

(0,38 + 0,47) 181 x 63

CMH =3586

(0,85) 11403

CMH =3586
