Determination of direction can be conducted with Method Stick of Istiwa and Astronomical Geodesy assumed earth as ball. Method Stick of Istiwa is technique determination of simple direction ,but have high accuracy storey;level, that is seen Phenomenon of Transit Especial of Above Sun of Makkah town, recognized also with term of Istiwa ' Azam ( Especial Istiwa). Istiwa ' Azam or of Istiwa Especial or especial transit is sun position moment reside in precisely in Zenith dot ( precise above head) a location where this event only happened in area among 23,5º Paralel North and 23,5º Paralel South. Especial Istiwa that happened in Makkah town can be exploited by clan of Muslimin in nations about different Arab specially time at the most 5 hours to determine direction by presisi use sun shadow technique. Istiwa ' Azam in Makkah is happened twice in one year, that is on 28 Mei at 12.18 Time’s Makkah and 16 July at 12.27 Time’s Makkah.
