Usages of stempel
Surat izin itu belum sah kalau belum ada stempel dari kantor fakultas.
That permission letter is not valid yet if it does not have a stamp from the faculty office.
Begitu kelas selesai, saya langsung mengirim foto stempel itu ke pembimbing supaya proposal cepat dibaca.
As soon as the class ends, I immediately send a photo of that stamp to my advisor so the proposal is read quickly.
