@Fargusno might not exactly be the no. 1 best (One of the exhibit in Gembira Loka is arguably better), could've need more foliage and water to the moat. But I agree that the bears have access to a large roaming space, grass floor, and a large shelter in the back.
@Fargusno there are cooperation between Ancol and Bandung Zoological Garden in the past, when SeaWorld sent their crocodiles to Bandung. Though I doubt breedings are in Ancol's mind regarding the bears, I can see them trying to get another bear when the original one passed on.
