Perhaps you should try some spelling variations:
mari belajar » hasil belajar
belajar mata » belajar dan, belajar anak
belajar al » belajar dan, belajar di, belajar anak
abnak usia » anak usia, anak rusia, anak usi
hati umat » bagi umat, hati kiat
al abnak » al abna, al abnaa, al abbas

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( mari belajar al abnak usia dini ) OR ( teori belajar mata ((hati pusat) OR (hati umat)) dini ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mari belajar al abnak usia dini ) or ( teori belajar mata ((hati pusat) OR (hati umat)) dini ))~".
• Adding a wildcard symbol may retrieve word variants: (( mari belajar al abnak usia dini ) or ( teori belajar mata ((hati pusat) OR (hati umat)) dini ))*.
