Nah yg menariknya, sekitar tahun 96-an, pihak BPN pernah membuat system informasi pertanahan (SIP) yang mengaplikasikan system UTM local lagi , disebutnya she UTM-3, dimana pembagian zona nya tidak per 6 degree, tapi per 3 degree. Dengan demikian antara instansi yg satu dengan yg lainnya pun masih belum seragam.
