1) Menghitung Nilai Rs

Nilai untuk bulan Januari

Rs = 0.25 + 0.54 n/N Ra

Rs = 0.25 + 0.54 x

Rs = 7.96 0.51

1.01 7.96

Untuk menghitung bulan-bulan lain digunakan rumus yang sama seperti untuk bulan januari

2) Untuk Menghitung Nilai ed

Untuk nilai bulan januari

ed = ea x Rh

ed = x

ed = %

ed =


3) Untuk Menghitung Nilai f(ed)


f(ed) = 0.34 - 0.44 (ed)0,5

f(ed) = 0.34 - 0.44 0.5

f(ed) =


4) Untuk Menghhitung Nilai f(n/N)


f(n/N) = 0.1 + 0.9 n/N

f(n/N) = 0.1 + 0.9

f(n/N) =


5) Untuk Menghitung Nilai f(u)


f(u) = 0.27 1 + u

f(u) = 0.27 1 +

f(u) =


6) Untuk Menghitung Nilai Rn1


Rn1 = f(t) f(ed) f(n/N)
