SOAL UJIAN KE 2
Di ketahui data-data sebagai berikut  :          
Lintang Mesjid                                    :           -2° 18’ 27.35” LS
Bujur Mesjid                                       :           109° 37° 50.54° BT
Lintang Ka’bah                                   :           21° 25’ 21.04” LU
Bujur Ka’bah                                      :           39° 49’ 34.33” BT

Atau
1 : Tan 93° 26’ 13” x Tan 92° 18’ 27.35” x Cos - 84° 40’ 53.62” = Shift Cos = °’”
C-P = 82° 3’ 34.03”

T = (( C-P + P ) : 15 ) + 12 – EOT + Kwd

T = (( 82° 3’ 34.03” + - 84° 40’ 53.62” ) : 15 ) + 12 - - 0° 9’ 53” + 0° 41’ 28.63” = °’”
