Halo teman! I think the verb "to have" is translated different in Indonesian.
The possible translations for "You have rice." would be:
Anda / Anda sekalian / Kamu / Kalian + miliki / memiliki / punya / mempunyai + nasi / beras / padi.
Note: "nasi" is used for cooked rice, "beras" is used for uncooked rice, "padi" can be used for plants, plantations, unmilled rice.
Selamat belajar! :)
