Wine making is not common in my country so it's difficult to buy wine ingredient especially Diammonium Phosphate (DAP) as yeast nutrient. After look in local shop, there's a shop selling Monoammonium Phosphate (MAP). Can we use it as yeast nutrient in wine making? Is there any journal or research that claim MAP safe to use as yeast nutrient?

Monoammonium phosphate and diammonium phosphate contain all the same chemical compounds (phosphate ions, ammonium ions, and hydrogen ions), the major difference is that MAP has a second hydrogen in place of the ammonium.
So, if you buy food grade stuff, it should be totally safe to consume, however, pH is determined by those hydrogen ions, so your wine may end up being more acidic. I'm not sure on this last part (you could calculate it with the Ka of H2PO4 vs HPO4). If you don't have other options, it's worth a shot.
