Analysis of Qibla Direction Determination Algorithm in Android Application KESAN
Keywords:
qibla direction, KESAN, Spherical Trigonometry, Planar TriangleAbstract
Many applications on android smartphones contain features to worship for Muslims. Of the various applications on the Play store, KESAN, which stands for Sovereignty of Santri, has features that can be said to be complete. These features consist of determining mandatory worship such as five-time prayers to sunnah worship. In addition, KESAN has features such as prayer, Salawat and Quran. One of the interesting features to study is the qibla direction feature. This article discusses the algorithms used in the KESAN application on Android. The research was raised with field research methods and qualitative approaches. In order to get data, the sources used are the KESAN application, interviews and observations in the field. The results of this study found that the application of KESAN uses the planar triangle method in determining the direction of the Qibla. In addition, in its application, this application is connected to the compass on the gadget so that the direction indicated is the magnetic direction of the Earth. In coding formulation, magnetic declination correction is not included. Therefore, the qibla direction shown by the application is far from accurate.
