Hi pam,
Not much you can do around the airport except golf. You should go to the city.
I assume you'll use AA to KK frm Jkt - traffic in jakarta is not too bad if you arrive on saturday; there's few places you can reach within 1 hour from airport + 2 hours waiting time - so, you'll have 4 hours for fun.
Here's some choices:
- shopping cheap garment at mangga dua
- Ancol dream land / fantasy world / sea world- but you have far better at home.
- old port sunda kelapa
- visit big malls (Taman Anggrek mall, ciputra, pacific place, ect.)
- visit several museums - can be interesting but typically not well maintain.
Indonesia Miniature parks is nice but probably a bit too far from airport.
Or let me know if you have any specific preference.
But on working hours; traffic in Jakarta very unpredictable - you may spend 3-4 hours or even more for roundtrip to those places.
I'll be in jakarta for 2 weeks mid of July
