The stall beside the entrance to Matahari supermarket (inside next to the escalater) has 2 gig + 1 gig free for about Rp 65,000 which lasts 30 days. I think he charges Rp 70,000 for the sim card so about Rp 135,000 for the 1st visit. I think the one outside Bintang Supermarket quoted Rp 50,000 for the card - depends where you are staying.
I'm sure others will know of other good deals to be had.
That was for Telkomsel which has been working fine for the last 6 weeks.
