The Setyaki temple is located in the Dieng temple complex, this complex is estimated to be built from the 8th to 9th century and is a complex of Hindu temples. This temple consists of 1 (one) main temple, there are no ancillary temples. However, what’s interesting about this temple is that there are batur-shaped buildings that are similar to dharmasala buildings, located to the west of Candi Setyaki. The nature of the Hinduan is seen from the relief of the deity figures found on the walls of the temple’s body parts. The relief is no longer complete, but it can be seen from the rest of the relief that there is still relief, namely the relief of Kartikeya. In Hinduism, Kartikeya is the god of war and one of the sons of Lord Shiva. Kartikeya has a vehicle in the form of a peacock. Identified as Kartikeya, because the character is depicted driving a peacock.
In addition to the Kartikeya reliefs, the Hindu religious characteristics found in the Setyaki Temple are also strengthened regarding the existence of a character depicted using the attributes of Lord Shiva. Even though it is no longer complete, the character’s attributes are still clear, in the form of camara / kebut lalat.
In addition to the reliefs of the figures mentioned above, this Setyaki Temple also has a quite interesting decoration. The decoration is in the form of animal reliefs, but further research is needed on the meaning of the animal reliefs. The animal relief panel is located in the lower body of the temple.
Candi Setyaki when found the remaining part is only a foot foundation, but the remnants of the building components are still around the temple building. Given these conditions, this temple requires conservation efforts. Efforts made to preserve the Setyaki temple buildings that have been carried out so far include; technical studies, initial environmental arrangements, search and experimental arrangements show that the temple building can be restored. The arrangement of the environment around this temple was first carried out in 2004. The arrangement was to reveal the part of the temple’s foot buried in the ground.
Restoration efforts were then carried out in 2008, namely the demolition of temple buildings and restoration to the foot of the temple and body I. After the activity was carried out the search and arrangement of body parts, the results of these activities formed the basis of the restoration of the body parts of the Setyaki temple in 2010 .
Over time and the occurrence of environmental changes in the Dieng region, especially the environment around the Setyaki Temple. These environmental changes are changes in land use whose use is less concerned with environmental aspects, especially in the hills around the temple complex. The hills around the temple complex are used by the community to grow vegetables. As a result of lack of attention to environmental aspects in land use, it causes erosion when it rains. One of the results of the erosion was in the area around the Setyaki Temple, so that the environment around the temple was covered by mud sediments. This condition also resulted in the emergence of puddles that inundated the Setyaki Temple complex. In addition, the stones that are made possible as part of the temple that were collected in the year were also covered again by the mud sediments. If the environmental arrangement is not carried out immediately, it can threaten the sustainability of Candi Setyaki. Therefore, this became the basis for environmental management activities in Candi Setyaki in 2013.
