It depends on the word. Bahasa is spelled as بهاس , using ه . That would be the default for most words. However some (not all) Arabic-origin words will be spelled with ح for example haram (حرام) and halal (حلال).
By the way, I've moved this thread to the Indonesian/Malaysian forum.
Please correct my mistakes in any language.
