Where does 'Pengiran' come from?

When I posted about Sultan Majid who died in China, there were three comments:-(1) Bro, the son of Sultan Abdul Majid Hassan is actually called Hsia-wang which means "Raja Kecil". His sister, Puteri Ratna Dewi, was married to Hwang Sinpeng (Awang Sinpeng or Ong Sum Ping)who was later bestowed with the title Pengiran Maharaja Lela. Again, the word Pengiran, I heard from somewhere is a chinese word
