to supplement previous answers, i'd like to add that sentence (1) is structurally correct and the meaning is perfectly understandable. however it does not comply with standard bahasa indonesia (indonesian) grammar. sentence (2) is structurally correct, totally comprehensible, and adheres to the standard grammar. use sentence (2) if you are in the formal occassion (e.g. writing official letter, company meeting, etc) and in colloquial occassion or even artwork like poet, sentence (2) sounds better.
