Perhaps you should try some spelling variations:
belajar bidang » belajar dan
mari belajar » hasil belajar
bahaya dasar » bahasa dasar, budaya dasar, bahaya asap
bidang sain » bidang sains, bidang air, bidang sarana
sain dr » sain di, sains di
asia al » asia ala, asna al, adiba al

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( mari belajar bidang sain dr drs ) or ( bahaya dasar anak ((asia al) OR (asma al)) dani ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( mari belajar bidang sain dr drs ) OR ( bahaya dasar anak ((asia al) OR (asma al)) dani ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mari belajar bidang sain dr drs ) or ( bahaya dasar anak ((asia al) OR (asma al)) dani ))*".
