Perhaps you should try some spelling variations:
dan keserasian » dan kesehatan
persada dunia » pertama dunia, perang dunia, pesta dunia
mari belajar » hasil belajar
belajar di » belajar dan
al persada » atlas persada
saat dewi » sang dewi
sari dewi » sri dewi

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 di ((saat dewi) OR (sari dewi)) ri ) OR ( dan keserasian al persada dunia dan ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mari belajar di ((saat dewi) OR (sari dewi)) ri ) or ( dan keserasian al persada dunia dan ))~".
• Adding a wildcard symbol may retrieve word variants: (( mari belajar di ((saat dewi) OR (sari dewi)) ri ) or ( dan keserasian al persada dunia dan ))*.
