Perhaps you should try some spelling variations:
pelaksanaan kuliah » pelaksanaan sekolah, pelaksanaan ibadah, pelaksanaan tugas
dan pelaksanaan » dan pelaksanaannya, dalam pelaksanaan, pedoman pelaksanaan
kuliah siswa » mulia siswa, karimah siswa, kalam siswa
seri belajar » teori belajar, mari belajar, cara belajar
dunia 1 » dunia 4
sman 2 » sman 1, sman 3, sman 4
sma 2 » sma n, smp 2, sma 1

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: (( dan pelaksanaan kuliah siswa ((sma 2) OR (sman 2)) ) OR ( seri belajar anak _ dunia 1 ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( dan pelaksanaan kuliah siswa ((sma 2) OR (sman 2)) ) or ( seri belajar anak _ dunia 1 ))~".
• Adding a wildcard symbol may retrieve word variants: (( dan pelaksanaan kuliah siswa ((sma 2) OR (sman 2)) ) or ( seri belajar anak _ dunia 1 ))*.
