The direction of the Qiblah is the direction of a place (location) to the Ka'bah in the Grand Mosque, Mecca with the closest distance. The purpose of "closest distance" here because the earth is round, so that the direction of Qiblah somewhere is actually more than one. For example, the direction of the direction of the city of Yogyakarta is two, namely facing northwest and southeast east. But the one used is northwest because it is the closest direction to the south east direction.
The formula of thisab direction Qibla, there are several models, namely:
North-North direction
Cotan B = sin⁡ a. cotan b: sin⁡ C - cos ⁡a.cotan C
Or
Cotan B = sin a. cotan b / sin ⁡C - cos⁡ a .cotan C
Or
Tan P = tan⁡ b. cos⁡ C Cotan B = cotan C.sin (a-P) / (Sin P
Or
Tan 1/2 (A B) = COS 1/2 (a-b) / COS 1/2 (a B)). cotton 1/2 C Tan 1/2 (A B) = SIN 1/2 (a-b) / SIN 1/2 (a B)). cotton 1/2 C B = 1/2 (A B) - 1/2 (A-B)
Or
Tan B = cos∅.⁡ tan⁡ 21 ° 25 ': sin⁡C - sin∅⁡: tan⁡C
With the above formula, it takes 3 elements:
"A" is the distance between the north pole to the latitudes that pass through the place / city which is calculated the direction of the Qibla, so that it can be formulated:
a = 90 ° - ∅ city ybs
"B" is the distance between the north pole to the latitude through the Ka'bah (∅ = 21 ° 25'21,04 ") so that it can be formulated:
b = 90 ° -21 ° 25'21,04 "
This side of b is fixed, ie 68 ° 34'38,96 "
"C" is the longitude distance, ie the distance between the longitude of the place calculated the direction of the Qibla with the longitude of the Ka'bah (39 ° 50 '), so for the location of Indonesia can be formulated:
C = α-39 ° 50 '
Example of Qibla direction calculation
Here is one example of calculating the direction of Qibla A location with known:
Ka'ba:
Latitude (∅) = 21 ° 25'21,04 "(LU)
Longitude (α) = 39 ° 49'34,4 "(BT)
Location A:
Latitude (∅) = -07 ° 28 '(LS)
Longitude (α) = 110 ° 00 '(BT)
Element Calculation
a = 90 ° - -07 ° 28 '= 97 ° 28'
b = 90 ° -21 ° 25'04 "= 68 ° 34'38,96"
C = 110 ° 00'- 39 ° 49'34,4 "
After knowing the elements, then calculate the direction of Qibla. This example uses the first formula:
Cotan B = sin⁡ a .cotan b: sin⁡ C-cos⁡ a.cotan C
Sehinnga obtained results:
Cotan B = 0.460385961
Tan B = 2.17209056
B = 65 ° 16'45,55 "(U-B) = 24 ° 43'14,45" (B-U)
The conclusion of the calculation, it can be seen that the direction of A's location Qibla is 65 ° 16'45.55 "from the north (parallel) to the west or 24 ° 43'14.45" from west to north.
