Abstract:
The mosque building, which is in the alley, sometimes escapes the monitoring of the 
accuracy of the Qibla direction. The difficulty of getting the sun's shadow directly into the mosque is one of the factors so that the instrument used to measure the Qibla only uses makeshift tools or only follows the location of the land used for the building. Such as Baiturrahman and Miftahul Ulum mosques in the Tamansari Village, with the position of building in an alley. The purpose of this  PKM  activity  is  to  assist  the  Mosque  prosperity  Council  (DKM)  in  verifying  the  Qibla direction of their mosque so that Muslims can pray towards the Qibla with the help of an accurate tool. This mentoring activity uses a participatory action research approach so that DKM can utilize the  sun  qibla  and mizwandroid  instruments  in  aligning  the  Qibla  direction  of  the mosque.  The results  of the  mentoring  activities  at  the  Baiturrahman  Mosque  and  Miftahul  Ulum  Mosque, namely the correction of the prayer rows conducted by the DKM of the mosque and the service team, where the difference in Qibla direction deviation is 8 degrees and 5 degrees, respectively. In addition, DKM and the service team have made corrections to the prayers’rows at the imam's place and the first row in each mosque by attaching Qibla direction stickers as a benchmark for the direction of the rows.
