Apparently, the first who pointed out about this "pyramid hill" is a private archeological research group called "Turangga Seta" , which firmly believes in the existence of pyramids in Indonesia and did publish their past findings on several online forums, as well as Facebook group.

However this group has often been ridiculed in the past by the Indonesian scientific community (check my signature as to some reasons why). Here is an illustration published by this group about the pyramid hill. I took the liberty to Photoshop this illustration in order to translate it from Indonesian into English:
