Here is the table of Possessive Pronoun in Indonesia
MY ----> SAYA (formal) / -KU (informal)
example : Buku saya/bukuku
YOUR ---> ANDA ( formal) / -MU (informal)
example : Komputer Anda/Komputermu
HER,HIS, IT --> -NYA
example : rumahnya
OUR ---> KAMI/KITA
example : apel kami
THEIR ---> MEREKA
example : orang tua mereka
BUT, there is another 2 ways, which in English is equal as "MINE, YOURS, HIS, HER, IT, OURS, THEIRS"
PUNYA/MILIK (-KU,-MU,-NYA,-KAMI,-MEREKA)
How to use?
--> THIS BOOK IS MINE --> BUKU INI MILIKKU/PUNYAKU
--> THIS APPLE IS YOURS --> BUKU INI MILIKMU/PUNYAMU/PUNYA ANDA
So, Indonesia has 2 ways in describing the "possession" but you can use based in a context and the structure of the sentence itself.
Hope it will help :)
