Archaeoastronomy is a multidisciplinary science consisting of astronomy and archaeology that studies the relation between sites, buildings, monuments, or tombs with stellar objects, such as the Sun, Moon, bright stars, and planets. The relation between ancient buildings with stellar objects is known as alignment, which is a projection of the declination of ancient buildings and coincides with stellar objects in the celestial sphere. Archaeoastronomy research in Indonesia is mostly done on ancient buildings called Candi. Previous studies have obtained results the possibility of alignment between the temples in Central Java with the position of stellar objects. Therefore, through this final project, looking for the alignment of temples in East Java with stellar objects and the relation between the orientation of the temples with their function. The alignments are calculated for 16 temples in East Java with azimuth value of each temple. The azimuth value, along with the altitude and latitude values for each temple, was obtained through the Google Earth Program which are converted into the declination value of the temple, then matched with the corrected declination of the stellar object. Based on alignment calculation at the horizon height and at various altitude with a range 0° – 90°, which results in possible alignment with stellar objects, specifically the Sun, Moon, and the Constellation of Orion. A total of 16 temples have a possible alignment with the zenith passage of Sun, lots of 7 temples have a possible alignment with the lunar minor northern standstill of Moon, and lots of 13 temples have a possible alignment with the stars in the Orion’s Belt. In addition, through literature study it is obtained that the orientation of the construction of temples in East Java had no relation with their function, but the choice of orientation was adjusted to the culture and beliefs of each kingdom that built the temple.
