When to go to Jakarta
Since few people go to Jakarta as such, Jakarta season is not the most sensible season for your trip.

If Jakarta becomes your main destination, then it's certainly best to go over the summer, preferably in August when the rainfall is at its lowest. July or September is also a good option.
However, even the rainy season need not be a major detriment to your visit; Jakarta is anything but a city you'll be walking in.
Since you'll spend a good deal of your time inside the sights, in restaurants, or in traffic and the ubiquitous traffic jams, the rain needn't bother you. Just wait for it to pass (very rarely does it rain for long periods at a time) and go out when it's not raining.
