Hi... this is very nice, a map from Indonesian's Capital. And I'm from Sumatra (if you don't know where Sumatra is, just take a look at world2.1-map)
Firstly let me give some little corrections on the name of several regions :
In West Jakarta:
Cengareng>> Ceng
kareng
Note : this is the first place you'll see, if you come to Jakarta, because the Jakarta' International Airport is in Cengkareng.
In South Jakarta:
Lama >> Kebayoran Lama (Old Kebayoran)
Baru >> Kebayoran Baru (New Kebayoran)
I am more familiar with the main roads in Jakarta, while with the borders I'm not so sure. But maybe I can help provide some solutions to the 4-way border-problems.
1. Kemayoran - Cempaka Putih - Kelapa Gading - Pulo Gadung
Kemayoran does not border Pulo Gadung, because from Kemayoran to Pulo Gadung we must go through Cempaka Putih.
2. Setiabudi - Mampang - Tebet - Pancoran
Setiabudi does not border Pancoran, because from Setiabudi to Pancoran we must go trough Tebet.
3. Tebet - Pancoran - Jati Negara - Kramat Jati
Tebet does not border Kramat Jati, because from Tebet to Kramat Jati we must go trough Pancoran
4. Kramat Jati - Makasar - Cipayung - Ciracas
I'm not so familiar with these regions, but the answer we can find here :
