Something like a hill station or viewpoint overlooking the city where you can get all your Instagram photos. Some also come to admire the sunsets.

Green Valley Tourist Park and Animal Park
Kind of second-rate amusement/water/zoological park in that animal and amusement upkeep isn't exactly optimal and the water is sometimes dirty. And you have to pay additional fees for certain attractions such as the water park and elephant rides after paying the general admission fee. Has ropes course, bumper cars, sun bears and deer on display, etc.
Botanical garden with waterway and some sandstone formations.
Overlook and coffee drinking respite. The view is a bit underwhelming, perhaps if the city were a little more attractive...
Iconic Bandar Lampung monument in roundabout.
Gita Persada Butterfly Park
This park has about 160 species of butterflies. It has photo spots, a cafe, and a museum describing butterflies.
Deer feeding area.
