Perhaps you should try some spelling variations:
mari belajar » hasil belajar
seri belajar » teori belajar, cara belajar
belajar anak » belajar dan
anak semut » anak semua, anak sejuta, anak sehat
dan tini » dan kini, dan dini, dan tip
r anwar » c anwar, ari anwar, drs anwar
usia di » usia dini, dunia di, mulia di

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 ((r anwar) OR (m anwar)) usia di ) OR ( seri belajar anak semut dan tini ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mari belajar ((r anwar) OR (m anwar)) usia di ) or ( seri belajar anak semut dan tini ))~".
• Adding a wildcard symbol may retrieve word variants: (( mari belajar ((r anwar) OR (m anwar)) usia di ) or ( seri belajar anak semut dan tini ))*.
