@ mimpimanis...would love to receive that or other storys by PM when its not suitable for an open forum, hehehe. if it's not much trouble ok.
Alright...which 'zone' your land is, can be found in your sertipikat/buku Tanah (Landcertificate)...there's a piece in it which says " Surat Ukur" (Letter of Size, How big the land is) on that there's written Keadaan Tanah : ????????? . The ??????? can be for example Tanah Perumahan - Residential, or for example Tanah Pertanian - agricultural.. On the next page you find a little sketch of the land, like location and neighboring landowners is on it.
BTW, the zoning is also mentioned on the paper one uses to pay tax..
Some extra 'unasked' info...the numbers on the bottom of the first page of the Certificate, are numbers you can use (the Notaris if PPAT) to check if there's anything 'wrong' with the land in question.
Don't know what you mean Spicyayam with " What it is referred to as on the title cerificate"
