Tropical Park in University of Indonesia (UI)

I visited my friend's campus, University of Indonesia (UI), in Depok, Indonesia. I was mesmerized, as the public parks around the campus were well designed. In my oppinion, University of Indonesia has exemplified some of the best tropical park's design. Its diversity of colour, vegetation, and textures are what makes these public parks enjoyable to see. I even think of, why don't cities in Indonesia design their parks like this? It could be recreational spots for its citizen, giving restorative effects in the midst of their bustling and hustling urban scene. It would be nice also to see people doing activities, gather to discuss, chatting with their friends, doing some yogas, held community gathering or even doing prayer - all take set within this kind of scenery!
