Rimba in this case is the Asian rainforest area of Burgers Zoo, featuring Sun Bear, Binturong, Hog Deer, Brow-antlered Deer, Reeves' Muntjac, Banteng, Southern Pig-tailed Macaque, Siamang, Salvator Monitor, Reticulated Python, Spectacled (Dusky) Langur, Gabriella's (Buff-cheeked Gibbon) and Sumatran Tiger (don't think I've missed anything there!).
The actual name 'rimba' is a Malay word, meaning 'forest' I believe.
