totally agree. 'turn around to the left/ right' sounds very odd and contradictory.
the best i can come up with here is 'turn sharp left/ right'.
that is, when you are making a turn that almost, but not quite, doubles back towards where you had been driving from.
otherwise, it's simply 'turn left/ right', 'turn around' or 'make/ do a u-turn' depending on what the indonesian actually means...
