"Saya mengirim surat ke anak-anak yang tinggal di perbatasan Jakarta."

Translation: I send a letter to children who live on the border of Jakarta.

[donny309620]

"near the border of Jakarta" should also be acceptable

[8enP1jip]

Should be "Who live on the border of Jakarta"

[NudibranchsRcool]

Agree
Also "on the border of" "at the border" or even "within the border" could work as well.

Reminder:

• The prefix pe- and the affix -an are used to form nouns

• Perbatasan means border

• The root is batas (verb) which means to limit

• Other words with this root: keterbatasan (limitations), batasan (boundary)
