Page "Comparison of Malaysian and Indonesian" Paragraph 9

Indonesia abandoned the spelling dj ( for the consonant at the beginning of the word ' Jakarta ') to conform to the j already in use in Malaysia, while the old Indonesian j for the semivowel at the beginning of the English ' young ', was replaced with y as in Malaysia.

Likewise, the velar fricative which occurs in many Arabic loanwords, which used to be written ' ch ' in Indonesian, became kh in both languages.
